Answer:columnar describes cell shape.

Simple describe the number of layers

Explanation: epithelial tissues are one of the four major tissues of the body.the others being nervous, muscular, connective tissues.

Epithelial tissues are made up of thin cells that cover the external and internal surface of the body.

The cells may form one layer or more and they occur in several shapes.if they form one layer ,it is called simple.if they form several layers,it is called stratified.

Some are called pseudo-stratified because the cells occur with varying lengths and give the impression of stratified but they are actually made up of one layer.

Simple columnar epithelium is a single layer of tall, closely packed cells. They possess cellular extensions ,such as microvilli in the small intestine, or the cilia in the female reproductive tract.

Negative feedback occurs when the output of a pathway ____________ input to the pathway. Feedback loops are used extensively to
Sveta_85 [38]

Answer:

Inhibits

Explanation:

Some mechanisms are essential for maintaining homeostasis in the human body. One of the most used mechanisms by our body is the negative feedback system. It causes a negative change from the initial change. As mentioned in the question, this often happens in the hypolamo-pituitary axis, such as when the adrenal cortex produces cortisol, this same cortisol inhibits the adenohypophysis and hypothalamus. It's also important to mention that deregulation in this process can lead to an undue chronic increase in cortisol and can lead to diseases such as anxiety disorder.

According to the theory of island biogeography, which of the following is not an island ecosystem?
den301095 [7]
<span>The correct answer is b. The open ocean. The definition of an island ecosystem does not have anything to do with water, but simply refers to an ecosystem that exists as a microcosm within a far larger, separate ecosystem. The ocean has lots of separate island ecosystems within it, but it itself cannot be referred to as one.</span>

How can the random distribution of alleles result in a predictable ratio?
levacccp [35]
Phenotypically and genotypically there are only two different ratios. If you think of a Punett square... 

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>
