Answer:
a products is a substance that is formed as the result of a chemical reaction here is the chemical equation A+B = C+D. hope this helps
Explanation:
Answer:
c.Both the mass of the objects and the distance between them
Explanation:
The Law of Universal Gravitation states that the force of gravitational pull between objects is directly proportional to the product of the mass of both objects and indirectly proportional to the square of the distance between them.
This means that as the product of the masses increases, the force increases. On the other hand, as the distance between the objects increases, the force decreases.
It can be computed with the formula:
Where:
F = Gravitational force
M₁ = Mass of object 1
M₂ = Mass of object 2
r = distance between the center of the masses
G = gravitational constant (this is a fixed number so the pull is not dependent on this)
Answer:
meiosis is for reproduction and mitosis is for growth and repair
Explanation:
Answer:
This is a pretty complex question with multiple parts to it. I will try to answer them and give a short explanation.
1. Steroid hormones are synthesized in the same cells where they function: False. Steroid hormones are produced in the adrenal glands, in the different portions of the gland. Each of them will go to different cells and produce their effects by directly binding to receptors on the cell´s nucleus, they do not stay to interact with the membrane of the cell.
2. Estrogen is a gonadocorticoid: True. Estrogen is primarily produced as a gonadocorticoid by the adrenal glands. They are part of the group of hormones that stimulate maturation of female body parts and maintenance of pregnancy when this happens. It also helps in the ovulation process.
3. Glucocorticoid receptors are membrane bound: False. Like all steroids, glucocorticoids, cross the plasma membrane and act directly on DNA by binding to receptors that cross into the nucleus itself.
4. Glucocorticoid receptors have a nuclear localization signal that is hidden until a glucocorticoid is bound: True. These receptors, known as GR´s (Glucocorticoid receptors) tend to be present in the cytoplasm and activate once a glucocorticoid crosses the membrane. These receptors will increase in number and carry the hormone towards the nucleus, where they will affect the DNA directly.
5. Two glucocorticoid receptors function as a homodimer: True. This is found the research done on how GR´s work to produce their effect. There has been research that shows they can work as heterodimers, but essentially, they work as homodimers.
6. Glucocorticoid receptors bind to GRE elements which are present on newly synthesized mRNAs. False. Essentially, and most simply, because glucocorticoids affect DNA, and the receptors will bind with DNA, not RNA.
