Answer:

c) degree of myelination of the axon

Explanation:

Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.

Factors that determines the rate of conduction velocity are:

  • axon diameter-larger diameter axons have a higher conduction velocity
  • sheeth-a myelin sheath increases the rate of impulse propagatio

Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.

Answer:

root hairs → 1. absorbs water and nutrients from the soil

vascular tissue → 2. consists of xylem and phloem

chloroplast → 3. the site of photosynthesis inside the cell

stem → 4. holds the leaves up high into the sunlight

leaf → 5. acts like an umbrella to absorb light  

terminal bud → 6. the growing part of the stem

taproot → 7. roots that reach deep into the ground

Explanation:

I have been able to match each term to its correct description.

From the above, we will discover that these are parts of a plant. These parts of the plant enable the plant to carry out photosynthesis and to exist.

The root hairs of the plant absorbs water and nutrients from the soil. When such are absorbed, the vascular tissues help to transport them.

The vascular tissue consists of the xylem and phloem. They  transport fluid and nutrients inside the plant. The vascular tissue is associated with two meristems which are the vascular cambium and the cork cambium. It is at the chloroplast that photosynthesis occur; where light energy is converted to chemical energy.

The stem holds the leaves firmly in order to project it to the sunlight. The leaf absorb sunlight which is needed for photosynthesis. The terminal bud is actually the part of the stem that is growing out. Taproot reach deep down the ground in search of water for the plant.

Dab most likely inhibits which reaction?a. phosphorylation of glucose. phosphorolysis of glycogen. export of lactate from cellsd
Pie

Dab most likely inhibits phosphorolysis of glycogen reaction.

<h3>What is phosphorolysis?</h3>
  • Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
  • It's comparable to hydrolysis.
  • A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
  • It's comparable to hydrolysis.
  • Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
  • The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
  • The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
  • It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.

Fill in the blank ____________________ is the closeness of a measurement to the actual value being measured. (1. Point)
Dahasolnce [82]
<span>Accuracy is the concept being studied here. Compared to precision, accuracy concerns how close to actually being "right" a value or measurement is. Precision, conversely, concerns how exact a measurement is (when using significant figures, decimal places, powers, or similar).</span>
