Explanation:
The circular rings of smooth muscles, that can contract to regulate the movement of the smooth muscles that can contract to regulate the movement of food through the gastrointestinal tract are known as sphincter muscles.
These two layers are outer layer and inner layer. The outer layer is longitudinal and the inner layer is circular. They contract rhythmically to squeeze food.

Infectious are more easily spread nowadays becuse of an increased population. The more the population increases, the bigger the advantage an infectious disease has. As of right now, because everyone is wearing masks, their immune systems are being weakened. Another reason for this is because of the increase in chemicals in our foods, which are now being transferred to our bodies. All of the medications people are taking also have an affect on the spread of disease; it gives diseases a chance to mutate.
Calico cats are predominantly female because they’re colouring is related to the X chromosome.
- Two X chromosomes are needed for a cat to have that distinctive tri-colour coat.
- If a cat has an XX pair, she will be female.
- Male cats have an XY chromosome pair, so they can’t be Calicos.

Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
<h3>WHAT IS MEIOSIS?</h3>
Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.
Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.
Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.
Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
