Epinephrine causes the enzyme glycogen phosphorylase to break down glycogen within a cell. Epinephrine performs this task on int

act cells, meaning cells that have a membrane (not just cell contents placed in a medium). What does this fact reveal

Answer:

The fact that it reveals is that:

Epinephrine binds to the receptor tyrosine kinase on the cell membrane and does not act on glycogen phosphorylase.

Explanation:

In cellular respiration, epinephrine is a neurotransmitter and a plasma membrane hormone receptor.  It is not a lipid-derived hormone, but rather an amino acid-derived hormone. As a result, they are unable to pass through the plasma membrane of cells. They bind to receptors on the outer surface of the plasma membrane through plasma membrane hormone receptors (receptor's tyrosine kinase of the cell membrane) because they are lipid insoluble hormones.

Unlike steroid hormones, lipid insoluble hormones (epinephrine) do not directly influence glycogen phosphorylase or the target cell because they cannot enter the cell and operate directly on DNA. The activation of a signaling pathway occurs when these hormones attach to a cell surface receptor; this activates intracellular activity and performs the hormone's specific effects. Nothing crosses through the cell membrane in this fashion; the hormone that binds at the cell's surface stays at the cell's surface, while the intracellular component stays within the cell.

Which nonmetallic mineral is used as a building material and also in the manufacture of steel?
kvv77 [185]
Limestone.

It is a sedimentary rock composed of calcite and aragonite. It is used as a building material mainly because it is easily available and easy to work with.

Limestone is used in the manufacture of steel as it is the primary raw material that helps to remove impurities from the iron ore and produces waste matter  that has low melting point and viscosity

A group of organisms that belong to the same species and live in the same place
faltersainse [42]
This can be identified as a population. In a population, the organisms are the same species and they have to live in the same area. For example, the population of cities are the head count of the species of human in that one area.

What are some possible consequences of a mutation? Give a specific example for each consequence you list.
Tju [1.3M]
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations<span> occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.
</span>

A single germ line mutation can have a range of effects:

<span><span>No change occurs in phenotype.
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span><span>Small change occurs in phenotype.
A single mutation caused this cat's ears to curl backwards slightly.</span><span>Big change occurs in phenotype.
Some really important phenotypic changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.</span></span>

What causes gene flow? (a p e x)
horsena [70]

Answer:

  i hope this helps!   :)

Explanation:

gene flow is a movement of the genes in or out of population. This movement can be caused by the migration of organisms that reproduce in the populations. Or the movements of the gametes
