Answer:

Cells convert energy stored in ATP into kinetic energy. - third choice

Answer: Option C

Explanation:

The energy that is stored in ATP can be used to derive the various processes of the body.

The third bond in the ATP is loosely bonded with the molecules which is broken down to allow more stronger bonds to form and provide energy for the cellular processes.

Through the process of cellular respiration the bonds are broken releasing the potential energy of the molecules in the form of kinetic energy that is used by the cells to do work.

Answer:

The rock on the right is foliated.

Explanation:

From the look, we can easily name the two rocks. These rocks are common metamorphic rocks. The rock on the right is a slate while the one on the left is quartzite.

From close observation, the slate is foliated and has a uniquely layered pattern. Foliation is a leaf-like appearance of metamorphic rocks and it is a result of metamorphic changes in a rock.

The protolith of quartzite is mostly sandstones which is a sedimentary rock.

The protolith of slate is also a sedimentary rock which are fined grained such as mudstone.

Pancreas

Explanation:

The pancreas controls body temperature, water level, and carbon dioxide level.

The cardiovascular, integumentary, breathing and muscular systems work collectively to help the frame hold a solid inner temperature. If frame temperature rises, blood vessels in the pores and skin dilate, permitting more blood to go with the flow near the skin's floor.

Hypothalamus is a segment of your mind that controls thermoregulation. while it senses your internal temperature turning too low or excessive, it sends indicators in your muscle groups, organs, glands, and worrying machine.

Answer:

Potential energy is gaining all the way to the top of the hill due to the increase of height (gravitational pull) on the skateboarder. At the top of the hill potential energy will reach its highest point. Then going down kinetic energy increases as potential energy decreases.

Explanation:

Answer : The potential energy and kinetic energy are always in flux. At the top of the hill, potential energy is at its highest and kinetic energy is at its lowest because the skateboarder stops for just a moment before being pulled down the hill by the force of gravity. At the bottom of the hill, kinetic energy is the highest because the skateboarder reaches maximum speed

A trace gas, carbon dioxide is necessary for photosynthesis. Nitrogen is the most prevalent gas in the atmosphere and is a key component of proteins and DNA.

Why is photosynthesis so important?

It is important because photosynthetic is the process through which plants use sunlight to change oxygen into carbon dioxide. Animals need oxygen to survive, whereas plants clean the air by taking harmful carbon dioxide out of it.

Why does photosynthesis occur?

The Sun Light energy triggers a chemical reaction that disassembles the water and carbon dioxide molecules and reassembles them to form glucose and oxygen gas. After the sugar is created, the mitochondria convert it into energy.

D. Electrons are more attracted to one of the atoms involved in a bond.

Electrons are more attracted to one of the atoms involved in a bond.

Polar molecules arise while atoms do not percentage electrons similarly in a covalent bond. A dipole bureaucracy, with part of the molecule carrying a slightly positive rate and the other part wearing a slightly bad price. This takes place whilst there may be a distinction among the electronegativity values of each atom.

Polar molecules occur when there may be an electronegativity distinction between the bonded atoms. Nonpolar molecules arise while electrons are shared similarly among atoms of a diatomic molecule or when polar bonds in a bigger molecule cancel each other out.

Answer:

Option D

Explanation:

In the general process of producing vaccines for any viral diseases, the viruses are cultivated in any carrier animal such as hen and then these virus fluids are extracted from the body of the test species. The virus in the virus solutions are inactivated (killed) and the virus solution i.e antigen is cleaned , purified  and tested to make vaccines for influenza virus.

Hence, option D is correct

Final answer:

Influenza vaccines are made from live weakened viruses, killed or inactivated viruses, or molecular subunits of the virus to build immunity and prevent the flu. They typically provoke an immune response without causing disease.

Explanation:

Vaccines for Influenza

Vaccines for influenza are primarily designed for prevention and are an essential tool in controlling viral diseases by building immunity. The influenza vaccines can be made from several different materials, including live weakened viruses, killed or inactivated viruses, and molecular subunits of the virus. These different types of vaccines work by stimulating the body's immune system to recognize and fight off the virus should the person become exposed to the actual virus in the future.

Influenza vaccines that use live weakened viruses are often called live attenuated influenza vaccines (LAIV). They contain a version of the virus that has been modified so that it cannot cause illness in healthy individuals. However, there's a very low risk that this type of vaccine could revert back to a harmful form. The inactivated influenza vaccines (IIV) contain viruses that have been killed and cannot cause the flu. Subunit vaccines, which include recombinant influenza vaccines (RIV), contain only pieces of the flu virus — generally protein subunits — that are enough to provoke a protective immune response without risking the introduction of live or killed viruses.

One example of vaccine production for flu includes growing influenza virus particles in chicken eggs, which are then harvested and chemically treated to render them noninfectious. These particles are purified and used to make the vaccine, which is administered by injection.

The types of immune cells that circulate in the body and provide immunity by producing antibodies are known as B cells. Thus, the correct option is D.

An Antibody may be defined as a type of protein that is synthesized by the plasma cells of B lymphocytes in response to specific antigens. It is a Y-shaped molecule with diverse forms.

B lymphocyte is one of the main types of lymphocytes that are classified under white blood cells which are the essential part of an immune system. B cells are further classified into plasma cells and memory cells. Plasma cells are responsible for the formation of antibodies that provides adaptive immunity.

Therefore, the types of immune cells that circulate in the body and provide immunity by producing antibodies are known as B cells. Thus, the correct option is D.

Because there are several factors that determine weight loss or gain and reducing calorific intake is just one of them (for reducing weight loss). Other factors that should be considered is exercise. Doing regular exercise ensures that the metabolic rate of the body is increased so much of the calories are burned even after intake. Having a lower metabolic rate can result to increased weight gain even with low calorie intake.

Answer:

(D). RNAi allows scientists to turn off one gene specifically to study its effect.

Explanation:

RNAi (RNA interference) can be defined as a process, which involves inhibition of gene expression by degrading the targeted mRNA molecules. This technique is widely used in laboratories to study the functions of different genes by targeting them.

For this, a dsRNA molecule is formed having a sequence complementary to target gene and introduced into the cell or organism. This RNA is recognized as exogenous RNA and triggers activation of RNAi pathway.

RNAi pathway leads to a significant decrease in expression of a target gene. Hence, physiological role of the targeted gene product can be check by studying the effect of decrease in its expression.

Thus, the correct answer is option (D).

Answer:

Friction

Explanation:

The efficiency of a machine depends upon the percentage ratio of output work to the input work. More the difference between the input and output work, lesser will be the efficiency of the machine. In real machines, the output is always less than the input because a lot of work is consumed against friction, resulting in reduced output.

The formula for efficiency is:

Efficiency= ( Output work/Input work) x 100%

Since the output will always be lesser than the input, the ratio of output/input will always be lesser than 1 and, therefore, the efficiency will always be lesser than 100%

Explanation:

Because nothing is eating the zooplankton then they will increase and the paddle fish will decrease because they are being hunted... Hope this helps!!!

Answer:

Option B, The population of paddlefish will decrease, while the population of zooplankton will increase.

Explanation:

Since, it is given that humans living around the river started  hunting the paddlefish thus their population will definitely decrease. As the number of paddlefish decreases the extent to which they feed on zooplanktons will also decrease. Thus, the population of zooplanktons will increase with no or limited disturbance.

Population of lamprey  which feed on paddlefish will start decreasing as their food i.e paddlefish has started declining.

Thus, option B is the correct answer.

The Sun is not burning through combustion with oxygen but operates through nuclear fusion, which allows it to emit energy for billions of years, unlike combustion which would only sustain it for a very short period.

The Sun does not burn in the way that we think of materials burning on Earth, such as wood or coal. In a combustion reaction, a substance reacts with oxygen to release energy in the form of heat and light. However, the Sun operates through a different process known as nuclear fusion, where hydrogen nuclei combine to form helium, releasing immense amounts of energy in the process.

Assuming the Sun was made entirely of oxygen and combustion was possible, when an oxygen atom combusts, it would release an electron-volt of energy. But given the chemical bond energy typical of combustion reactions (about 1 eV), the Sun would have a very short lifespan, far shorter than what we observe. Even if the Sun were made of the best anthracite coal and oxygen, it could only sustain its current level of heat output for less than 1500 years given the huge amount of energy it emits.

Therefore, it is not combustion that powers the Sun, but rather the process of nuclear fusion, which is capable of producing the Sun's energy for billions of years.
