The DNA sequence is a code with instruction to assemble amino acids which then form proteins.

DNA is a hereditary material  which is present in human beings as well as all other living organisms.  Every cell which is present in an organism's body has DNA  which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.

Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.

DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule  and a phosphate group. A base, phosphate  sugar are together called as nucleotides.

Answer:

planetesimals

Explanation:

:)

The small bodies that formed the planets after the solar system began to form are called planetesimals; this is the third option, as the planetesimals are essentially small, rocky or icy bodies that formed in the early stages of the solar system's formation.

They were the building blocks that eventually collided and merged to form larger bodies, such as planets and moons. Terrestrial planets, like Earth, Mercury, Venus, and Mars, are formed from the accretion of these planetesimals. The planetesimals collided and stuck together, growing larger and larger until they became the solid, rocky planets we know today. Dwarf planets, on the other hand, are also small bodies in our solar system, but they did not clear their orbits of other debris, which is one of the criteria used to distinguish a planet from a dwarf planet.

Hence, the small bodies that formed the planets after the solar system began to form are called planetesimals, which is the third option.

Answer:

ADP converts to ATP

Explanation:

An electron transport chain is a series of complexes that transfer electrons from electron carriers such as NADH and NADPH to electron acceptors, such as oxygen, through reduction and oxidation reactions that occur simultaneously. It couples the transfer of protons (hydrogen ions) across a membrane which enhances synthesis of ATP from ADP and inorganic phosphate.

Nitrogen is an element vital to all life processes on Earth.  To appreciate the importance of nitrogen in our biosphere, simply realize nitrogen comprises 78% of the atmosphere, and is embedded in every living tissue!   It is a component of amino acids, proteins and nucleic acids.   With the exception of carbon, nitrogen is the most universal element of life  Put simply: Life could not exists without nitrogen.  Aside from organic development, nitrogenous compounds are also required by some organisms for metabolic functions and respiration.  Nitrogen exists in many states.  In its most common gaseous state of N2, nitrogen forms very strong covalent bonds that can only be broken when great force or energy is applied (e.g. seismic event or lightening), or by particular bacteria species which use nitrogenous compounds for metabolism.  The fact is various bacteria are critical to every step of the nitrogen cycle.  It is these bacteria and their specific roles that are of particular interest to reefkeepers. It is never fully "completed." There is no end to the nitrogen cycle; Matter can neither be created or destroyed, and nitrogen is no different.

Answer:

Great amounts of energy are released in the core of a star as lighter elements combine and form heavier elements during the process of nuclear fusion.

Explanation:

Final answer:

The process where energy is released in a star's core through the combining of lighter elements is known as nuclear fusion, a crucial process for the energy and synthesis of heavier elements in stars.

Explanation:

The process through which great amounts of energy are released in the core of a star as lighter elements combine to form heavier elements is known as nuclear fusion. During nuclear fusion, energy is released as light atoms fuse together; this is especially true for elements like hydrogen and helium. This process occurs in stars like our Sun, where hydrogen nuclei combine under immense gravitational pressure to form helium, releasing a significant amount of energy. In the lifecycle of stars much more massive than the Sun, nuclear fusion continues until the core is primarily iron-nickel, after which no more energy can be produced through fusion because any reaction involving iron is endothermic. The cessation of energy production due to fusion leads to the gravitational collapse of the star, ultimately resulting in a supernova, where elements heavier than iron are produced and scattered into space.

The correct answer is B. are produced. NADH atoms are produced as an overall result of the citric acid cycle. NAD+ is reduced to NADH, which is then used in the electron transport chain for ATP production.

During the citric acid cycle, a crucial part of cellular respiration, NAD+ is reduced to NADH. This process involves the transfer of electrons to NAD+, forming NADH, which then carries these electrons to the electron transport chain for ATP production.

To give further context, the electrons added to NAD+ during the cycle are crucial in producing ATP, as these reduced forms, NADH, and FADH2, play significant roles in energy production. They are subsequently used in the electron transport chain to generate ATP, which is vital for cellular activities.

The factors that effect the speed of sound are not random effects based on a whim but exact scientific principles that effect the speed of sound.  The exact number 1,126 feet per second is taken in some precise conditions:  in dry air at 68% Fahrenheit.  In other words in the most “average” conditions possible.  Therefore a great average, but it is variable.

Here are the factors that effect the speed of sound:

♦  Medium

Medium has a huge effect of the speed of sound.  When most people discuss the “speed of sound” they are talking about the propagation of sound waves through the medium of “Air”.  For anyone who has gone underwater and listen to people talking above it is likely that one would notice the muted an “odd” way that voices sound underwater.  This is because the “medium” of water greatly bends, distorts and changes the speed of sound wave.

There is a whole aspect of science that measure and defines the effect of different mediums (gaseous and liquid) on the speed of sound.  This is called Fluid Dynamics.  Underwater communication is possible if you understand how this wave propagation as well as another important factor (pressure).

Because of elasticity of materials sound will, as a rule of thumb, generally travel faster in solids than in liquids and faster in liquids than in gases.

♦  Temperature

Temperature has a large effect on the speed of sound.  Not as much as the “Medium” does, but far more than anything else.  Temperature affects the speed of sound because temperature can affect the “elastic” qualities of different mediums.  At the very basics lower temperatures will decrease the speed of sound while higher temperatures will increase the speed of sound, all other factors being equal.

♦  Pressure

Pressure is the final factor that has a significant impact on the speed of sound.  The effect of pressure on the speed of sound is due to the materials inertial properties.  In short, the more pressure that is applied to the material or medium the denser it becomes and the greater the “inertia” becomes.  This makes any interactions between particles slower.  Therefore the speed of sound throughout the medium is slowed due to the greater pressure.

Explanation:

Answer:

When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.

So it is reversible reaction.

Explanation:

Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.

In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.

When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.

So it is reversible reaction.

Answer:

This is a reversible reaction because you can boil the water to make water vapor and when the water vapor is cooled down, it ill turn back into its original liquid, water. This occurs because of hydrogen bonding between water molecules.

Answer:

Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.

Explanation:

when there is a higher concentration of water inside the cell, water will begin to move out of the cell, eventually creating a hypertonic solution in which the cell shrivels and shrinks.

Final answer:

When a cell shrinks and shrivels due to osmosis, it means that water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.

Explanation:

Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. When a cell shrinks and shrivels due to osmosis, it means that water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell. Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic.

Answer:

Black

Explanation:

It is only possible to correctly visualize the color of a body due to the reflection that the light present in the environment. If there is no light and the environment is dark, no light will be reflected and we will see the body in black.

in other words, we can say that color is not a particular feature of the object, but rather a feature that depends on the light that illuminates the environment in which that object is.

When light hits a red shirt, that shirt absorbs all the colors present in the ray of light, except for the red light that is reflected in all directions. Without light in the room, there is no reflection, so the shirt is black.

A red shirt will appear black in a room that is entirely dark, because color perception is reliant upon light. When there is no light to reflect off the shirt, we can't observe any color, hence the shirt appears black.

If a red shirt is in a room where all the lights have been turned off and the room is entirely in the dark, the shirt will appear to have the color black. This is because color perception in humans is dependent on light. Whenever we see colors, we're observing the wavelengths of light that an object reflects. Red objects, for example, absorb all colors of light except for red, which they reflect. However, when there is no light in a room, there are no light wavelengths to be reflected and hence, no color can be observed. Therefore, the shirt would appear black, the color we associate with the absence of light.

Answer:

C

Explanation:

Answer:

a. Location A

Explanation:

Region A, shown in the graph above, will show cooler summers and warmer winters because it is located close to the ocean. This is because water has a high amount of latent heat, which requires a large amount of energy for the water to evaporate. This allows the heat exchange between the environment and the water to be carried out without changing the temperature.

As a result, regions close to bodies of water have great stability in their temperatures, presenting colder summers and warmer winters.

Answer:

Earthquake prediction involves the scientific field of of seismology.

Explanation:

Answer:

Earthquake prediction

Explanation:

The nature of predicting when an earthquake will occur is known as earthquake prediction. Despite countless research into earthquake prediction, it has not been scientifically possible to develop a completely safe method for predicting earthquake, even though some researchers have announced possible forms, none have been confirmed in practice.

Because of the difficulties, all advances in earthquake prediction are centered on earthquake monitoring rather than forecasting. Despite the seismograms and some work with high-precision GPS equipment that can see plate offsets, it is difficult to assess where a break will occur. Studies have also sought to monitor cracks, but there is no prediction of equipment that points out where the quakes will occur.

Natural gasses are gasses formed deep beneath the Earth's surface that are used to fuel things like cars and motercycles. They are considered as Fossil Fuels.

They are formed when natural materials such as decomposing plant and animal matter are exposed to intense heat and pressure underground for over millions of years through this prosses they transform. natural gasses are not found in equal amounts all around the globe this is because each environment has different heat temperatures, ground height, some might not have as much plant life or animal life there for a place like a marsh or swamp will probably have more considering it's mostly warm in these areas and there's a lot of wild life liveing there.

In 2019 the US used 31 trillion cubic feet of natural gasses, in 2016 the US consumed 731,071,000 Tons of coal, and in 2017 the US used 7.28 billion barrels of petroleum products this is because they want CO2.

CO2 is in Natural gas so when it burns it's releasing what it's made up of along with the CO2. It is made up of CO2 materials while it also gets rid of the oxegen.

Natural Gasses produce 117lbs. per MBtu(Million British thermal unit), Coal produces 200lbs. per MBtu, and Oil produces 160lbs. per MBtu. this is how it is used.

Solar, Wind, and Hydroelectric are all Renewable and considered Carbon-free energy scourses. Nuclear power is also considered carbon-free because it does not burn like coal. Wind and Solar can be available everywhere, hydroelectric would only be near water and solar might not be very efficient in places that don't get a lot of sunlight so they have nucular because it powers a LOT of places it powers up to 10.7% of all the energy.

I would not consider it clean but I would say it's one of the cleaner options. It still produces a considerable amount of CO2 into the atmosphere and the process for getting a hold of it probably also has some downfalls to the environment. This procces keeps the envorioment clean and keeps the world more safe.

CO2 destroys the envoroiment and takes the homes of animals and plants. People need to use claener ways to help the enviroment they can do this by useing clean energy sorces, and learn about the history of the energy scources, and how much is used.

what phrase are you talking about?

An irregular galaxy is one that lacks the defined shape of spiral or elliptical galaxies, often has active star formation, and contains both young and old stars. They can be reshaped by gravitational forces or collisions, and historical observations show that they were more common in the past.

Phrases that describe an irregular galaxy include not having regular shapes like spiral or elliptical galaxies, typically possessing lower masses and luminosities compared to spiral galaxies, appearing disorganized, and often experiencing relatively intense star formation activity. Irregular galaxies contain a mix of young population I stars and old population II stars, highlighting their diverse age range. These galaxies can be subjected to deformation by gravitational interactions with more massive galaxies or collisions with other galaxies, leading to their irregular shapes. The majority of galaxies are irregular, and the Large and Small Magellanic Clouds are examples of such irregular galaxies. In the distant past, irregular galaxies were more common and frequently interacting, as seen in deep field observations like the Hubble Ultra Deep Field.

The plastic baggie was permeable to Iodine.

Explanation:

The plastic bag is a good example of the cell membrane as it is semipermeable.  Experiments show that a plastic bag is semipermeable. Take corn starch nin a plastic bag and dissolve it in water. Now take a beaker with water and add Iodine indicator. The colour changes to brown.

Place the plastic bag inside the beaker. After some time the colour of the starch solution turns blue from white. But the solution in the beaker is of the same colour.This shows that the plastic bag has numerous tiny holes and thus acts like a semipermeable membrane allowing Iodine to pass through it. Apparently it retains the large starch molecules from passing out.

Answer:

Answer is B.

nitrogen (78.10%), oxygen (20.90%) - this combination of gases dominate the Earth’s atmosphere.

Explanation:

The atmosphere of earth is a gaseous layer which surrounds the earth. It  protects the life on earth by absorbing harmful ultraviolet radiation, reducing temperature extremes, maintaining the existence of  liquid water on the earth's surface and warming the surface. The atmosphere consists of many gases including some pollutants and greenhouse gases. Nitrogen is the gas present in the atmosphere most abundantly while Oxygen and Argon take the second and third place. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc. There are five layers of atmosphere. Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere ,which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Stratosphere (12 to 50 km) is the second layer where jet aircraft and weather balloons fly. It contains the ozone layer that absorbs harmful radiation from the sun.  Mesosphere (50 to 80 km) is the third highest layer and the coldest part of the atmosphere where most meteors burn up upon entering in to the atmosphere. The fourth layer is thermosphere (80 to 700 km) where the International Space Station orbits earth and the space shuttles flew. Exosphere (700 to 10,000 km) is the outermost layer where the atmosphere merges into outer space. Most of the satellites orbiting earth are found here.

It is necessary for our breathing. cellular respiration take place effectively in the presence of oxygen and produced more ATP.

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Answer:

The DNA is made up of two strands which are joined through the hydrogen bonds present in the nucleotides. There are 4 nucleotides which make up the DNA. Adenine of one strand pairs with thymine of the other strand. Cytosine of one strand pairs with guanine of the other strand. These bonds keep the DNA double helix intact. Information stored in the DNA is unique due to the sequence of pairing of these nucleotides.

The DNA encodes information through the proper sequencing of the nucleotides. These DNA messages encode for certain types of proteins.

The chemical structure of DNA, with its double-helix shape and specific base pairing properties, allows it to store and transmit heritable information in cells.

The chemical structure of DNA makes it possible to be the primary source of heritable information in cells. DNA is composed of two strands that are connected by nucleotides, which are made up of a sugar, a phosphate group, and a nitrogenous base. The sequence of these nitrogenous bases along the DNA molecule carries the genetic information that is passed on to offspring.

The complementary pairing of nitrogenous bases allows DNA to replicate itself during cell division, ensuring that the heritable information is faithfully passed on. For example, adenine on one strand always pairs with thymine on the other strand, while guanine always pairs with cytosine. This base pairing rules ensures the accuracy of DNA replication.

Overall, the double-helix structure of DNA and its specific base pairing properties allow it to store and transmit heritable information, making it the primary source of genetic material in cells.
