Answer:
RNA Polymerase
Explanation: General transcription factors position RNA polymerase at the start of a protein-coding sequence and then release the polymerase to transcribe the mRNA. Activators enhance the interaction between RNA polymerase and a particular promoter, encouraging the expression of the gene.
explain how redox reactions are involved in energy exchanges
Answer:
In redox reactions, energy is released when an electron loses potential energy as a result of the transfer. Electrons have more potential energy when they are associated with less electronegative atoms (such as C or H), and less potential energy when they are associated with a more electronegative atom (such as O).

Answer:
protein, speed up, active site, substrate, reusable, shape, denaturation
Explanation:
The biological molecule _protein usually makes up enzymes. Enzymes are used to _speed _up the rate of a reaction within an organism. Each enzyme has a special shape called an _active _site where a _substrate binds to break down into different products.
The enzyme can keep breaking down millions of substrates because it is _reuable If an enzyme’s environment changes, it will not work effectively because the _shape of the active site changes. This change is called _denaturation.
Fill in the blanks.
The biological molecule is a numerous substance that makes up the cells and living organisms. Has a wide range of sizes and structures. The enzyme is a substance that performed the works of a catalyst in living and regulates the chemical reactions.
Hence the answer protein, speed up, active site, substrate, reusable, shape, denaturation.
The biological molecules that makeup up the enzymes are known as protein, helps to speed up, the rate of the reactions within the organisms, and lead to the special shape known as an active site. There a substrate binds the break down into various products.The enzyme can be broken down into millions of parts and due to they are able to reusable and can change their shapes, the change in the enzymes is called denaturation.Learn more about the fill-in-the-blank.

How does galaxy composition typically relate to the age of the stars in the galaxy? (1 point)
Star aging emits gas and dust, so galaxies with the youngest stars typically have the lowest proportions of dust and gas.
Star formation and the presence of young stars is common across galaxies, regardless of the proportions of dust and gas present.
Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.
O Star formation consumes dust and gas, so galaxies where stars are oldest typically consist of higher proportions of dust and gas than other galaxies.
H
Galaxy composition typically relate to the age of the stars in the galaxy
through Stars being able to form from dust and gas, so galaxies with
younger stars typically consist of higher proportions of dust and gas than
other galaxies.
Components of a StarDustGasThe age of stars are usually determined through the amount of gas and dust
present in them. Stars burn gas to emit light and the younger ones have
more proportion of gas present than the older ones. The older ones have
less proportions due to more gas being burned over time.
The stated facts therefore makes option C the most appropriate.

Answer:
the birds would either have two choices. they can eithe starve or they could adapt and eat the rice. they eventually would adapt if they wanted to stay alive and thrive or they would simply become extinct
Explanation:
If all of the bird types in this activity flew to an island where no birds had been before and the only food available was rice then they either starve or adapt and eat the rice.
What is adaptation?An adaptation can be defined as the heritable behavioral, morphological, or physiological trait which has evolved through the process of natural selection of a species, and maintains or increases the fitness of an organism of a species under a given set of environmental conditions and time.
In this activity, if all of the bird types flew to an island where no birds had been before and the only food available was rice then they either starve or they could adapt and eat the rice.

what is the specific function of the structure labeled f?
Answer:
The muscle spindle indicated by F functions as a proprioceptor that is responsive to changes in the length of the surrounding muscle.
Explanation:
The specific function of the structure labeled f is proprioceptor that is responsive to changes in the length of the surrounding muscle.
What is the function of the muscle spindle?The muscle spindle is activated whenever the weight of the body, tending to bend the knees, stretches the muscles. Stimuli are sent to the spinal cord and through the motor nerve and the muscles contract to counteract the action of gravity.
The Muscle spindle is a proprioceptive sensory receptor spindle composed of muscle bundle fibers. Its main function is to signal changes in the length of the muscle on which it is located. Muscle Spindles are structures responsible for mechanical myo-integrity and regulation of muscle contraction/distension.

4. How would having a high blood viscosity affect your ability to climb stairs? Explain your answer interms of homeostasis of oxygen/carbon dioxide levels
Having a high blood viscosity will slow down ability to climb stairs. This is
because high blood viscosity is associated with high blood pressure.
The binding of oxygen to the blood is reduced in a blood with high viscosity
as there is difficulty in the transport of blood for oxygenation due to its
higher density. This allows fro accumulation of carbon dioxide in the blood
which is harmful to body cells.
High blood viscosity will therefore reduce one's ability to climb stairs and
perform other activities.

Explanation:
Tanya planted seedlings in her garden over the weekend. The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart. Tanya has a measuring tape that has values in centimeters. As we know 1 meter = 100 centimeters . Therefore, 0.2 meter = 0.2 × 100 = 20 centimeters. So Tanya need to be planted 20 centimeters apart.
Quick question: did I do this correctly?
1. Why does the angle of the sun at noon seem to change at different months throughout the year?
2. How does this create seasons?
Answer:
1. The earth orbit is slightly elliptical, and the earth axis is tilted by roughly 23.5° to the orbit. These to factors combine to make the an analemma. But in the winter, When the Earth is on the other side of orbit, the Earth's north pole is tipped away from the Sun, so at noon the sun doesn't get as high.
2. The earth's spin axis is tilted with respect to it's orbital planet. This is what causes the season. When the earth's axis points towards the sun. it is summer for that hemispheres. Midway between these two times in spring and autumn, the spin axis of earth points 90 degrees away from the Sun.
what would happen to the carrying capacity of the ecosystem & why
Q-a volcano covers an area with 2 feet of lava
Answer:
The carrying capacity would shoot downward.
Explanation:
The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).
Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).
