Answer:

The correct answer is  a. can be activated by the release of epinephrine.

Explanation:

Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

In which layer of the sun does nuclear fusion occur? Explain how the nuclear fusion is created
Aleksandr-060686 [28]

A large cloud of gas (hydrogen) and dust a nebula begins to collapse

The collapsing cloud begins to spin

The spinning collapsing cloud flattens into a rotating disk

Material in the disk begins to accumulate in the center

As the material coalesces in center, it becomes dense, compresses, and heats up.

More and more material coalesces to form a protostar.

The protostar continuse to accomulate material from the surronding disk and grow.

Eventually, the protostar becomes massive enough, dense enough and hot enough to cause the process of  nuclear fusion to begin.

Nuclear Fussion isotops of hydrogen atoms (deuterium, tritium) combine to form helium atoms, energy, and subatomic particles.

Once nuclear fusion begins the protostar's “ignition” to nuclear fusion creates a solar wind that drives remaining gas and dust to the outer parts of the disk.

Then the young star stops accumulating material.

Explain the concept of growth using these terms: differentiate, meristem, elongation, and vascular cambium.
egoroff_w [7]

Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.

hope this helped luv :)
