Answer:

1. Many vertebrates have teeth, and chewing (mastication) breaks up food into small particles, expanding its surface and mixes it with fluid secretions, which makes it possible to digest. Teeth are located in the mouth of animals, where the digestive process initiates.

2. The stomach, which resembles a bag-like shape, can either fold up when empty and expand like a balloon when it fills up with food. By doing this, the area of activity of the gastric juice is expanded, increasing the efficiency of the digestion. Food enters the stomach from the esophagus.

3. The villi and microvilli present in the epithelial wall of the small intestine, are fingerlike projections that greatly enhance the surface area of the small intestine. In humans, this surface area is 300 square meters and it is over this large surface that the products of digestion are absorbed.

rodikova [14]

Cancerous growths are clonal in origin because of cancer cells originate from a single cell that has accumulated genetic changes during cell division.

The human body contains several billion cells. Cells are the teeny, tiny building blocks of our tissues and organs. Every one of us was once a single cell. That cell divided into two new cells after internal replication.

Cells become abnormal when the DNA, which holds the instructions needed for cells to operate, is damaged. The cells they make after that will not be similar to healthy ones. Along with having a variety of appearances, they might also possess different traits. The medical word for this kind of abnormal cell proliferation in body tissue, including skin, is dysplasia. As long as there aren't many abnormal cells and our immune system controls them, we won't get sick from them.

Sometimes these cells can vanish on their own. Only when these cells continue to change and start to divide erratically, leading to lumps or growths, does one of the more than 200 diseases recognized as cancer become apparent. These kinds of growths are tumors.

The complete question is:

Cancerous growths are clonal in origin because of cancer cells __________.

multiple choice questions.

(A). can invade healthy tissues originating from a single cell that has accumulated genetic changes during cell division

(B) can migrate to other areas of the body and form secondary tumors at the new sites

(C) can form a tumor that is localized only at one site

Gelneren [198K]

Answer:

Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome.
