What structure in fish allows for oxygen to be filtered out of water.

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.  

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.

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.

Answer:

The correct option is B) Photosynthesis.

Explanation:

Photosynthesis can be described as a process in which plants convert carbon dioxide and water into oxygen and glucose by using light energy from the Sun. Photosynthesis is a process that occurs in plants, some algae and cyanobacteria. Hence, option B is correct.

Other options like option C are false because, during aerobic respiration, oxygen is utilized instead of being produced. The process of respiration is opposite to the process of photosynthesis.

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.

BECAUSE BOTH THE ORGANISMS EXTRACT NUTRIENT FROM THE AVAILABLE RESOURCES.

B. Neither organism can extract nutrients from available resources.

Explanation:

The organisms without cell and the with the cell can effectively get their nutrients from the available resources in the environment.

The autotrophic prokaryotes they obtain energy from the process of photosynthesis and chemosynthesis, the chenosynthesis prokaryotes is the responsible for chemosynthesis process,  in this process the energy is extracted in the form of the oidation of inorganic compounds .

In Eukaryotas the energy sources obtained in the form of the sunlight.

Final answer:

Both prokaryotic and eukaryotic cells can extract nutrients from available resources, despite differences in cellular structure such as the presence or absence of a nucleus.

Explanation:

The answer to the question is based on an understanding of cell theory and cellular structures in different types of organisms. The cell theory states that all living organisms are composed of cells, and these cells are the basic unit of life. Additionally, it states that new cells arise from existing cells. Both prokaryotic and eukaryotic cells are capable of extracting nutrients from available resources, despite the presence or absence of a nucleus. Prokaryotic cells, which lack a nucleus, manage cellular processes in different ways than eukaryotic cells, which possess a nucleus; however, both types are equipped to obtain and process nutrients necessary for survival.

Answer:

It combine with hydrogen and two electrons form water.

It is necessary for our breathing.

Explanation:

Oxygen during cellular respiration is very important.

It combine with hydrogen and two electrons form water.

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:

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.

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:

Microbial control agents can be described as agents which will inhibit or prevent the growth of microbes. Hence, they will prevent the damages caused by microbes.

Microbial control agents can either inhibit the growth of microbes. In this way, the population of the microbes will not expand and hence, the effect of the microbe on a host will be controlled.

Other microbial control agents kill the microbes and hence, control the effect of microbes.

Microbial control agents affect microbes by inhibiting cell wall synthesis, protein synthesis, DNA replication, transcription, damaging cytoplasmic membranes, and disrupting metabolic pathways.

Microbial control agents, such as antibiotics and disinfectants, exert their effects on bacteria through various mechanisms. These agents can target and damage critical bacterial structures and macromolecules, leading to the inhibition or death of the microbial cells. Here are six different ways in which these chemical agents can affect bacteria:

The effectiveness of these agents varies among different bacteria, with some species being naturally resistant or developing resistance over time. Gram-positive bacteria and Gram-negative bacteria may respond differently to various control agents due to structural differences in their cell walls.

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.

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.

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:

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.

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.
