Biology

Amanda [17]3 years ago

Primary Growth 
The root system also has an apical meristem, known as the root apical meristem<span>. This acts in much the same way as the shoot apical meristem, causing extension growth. The main difference is this growth goes down into the ground, and roots, not leaves and branches, come from the root apical meristem. 
</span>Secondary Growth
<span>The width of a plant, or its girth, is called </span>secondary growth<span> and it arises from the </span>lateral meristems<span> in stems and roots. As with apical meristems, lateral meristems are regions of high cell division activity. However, the cells they make grow outward rather than upward or downward. Eudicots use lateral meristems to add to their width; monocots, however, do not experience secondary growth.</span>

Primary reinforcers are related to secondary reinforcers in which of the following ways?
LuckyWell [14K]
You didn't provide us with any possible ways? Primary reinforcers are, however, types of reinforcers where they immediately elicit a reward or reward-like behavior once they are applied in a situation. An example would be apple juice. 

Secondary reinforcers on the other hand need to be associated with something for them to become reinforcers or they provide rewards in a non-direct way. An example would be money.

This is the main relationship between them.

According to the fossil record found in these sedimentary layers, what conclusion can be drawn about the movement of life to lan
timofeeve [1]

The correct answer is: B) As land plants became more complex, animal life did as well.

This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.

So, plants were one of the earliest organisms to leave the water and colonize land.

Compared to unmyelinated axons, myelinated axons?
Furkat [3]

Answer:

A. Conduct impulses faster.

Explanation:

Myelinated axons are called that way due to the myelin sheath that surrounds them. Myelin has an insulation property so electrical impulses cannot travel through it, except on certain sites called Nodes of Ranvier. In order for electrical impulses to be conducted on myelinated axons they must "jump" from one Node of Ranvier to the next, and thus conduction is faster. This is called saltatory conduction.
