A cladogram is a type of graph that shows how closely related different types of organisms are in an evolutionary context. It resembles a tree, with various organisms being placed at the end of each branch. If two organisms have a close common branch, they are more closely related than those who have more distant branches. Since DNA, or corresponding protein sequences are more similar in closely related species, and more different in more distant species, a biologist can use those sequences to numerically determine how closely related three species are.

A beaker contains two solutions of salt dissolved in water. The two solutions have different concentrations (measured by molarit
mihalych1998 [28]

Answer:

c) There will be a net movement of salt from side B to side A

Explanation:

According to the given information, the solution at side A is hypotonic to the solution at side B. The separating membrane is permeable to salt and would allow the movement of salt from the hypertonic side B to the hypotonic side A. Transport of substances down their concentration gradient is a passive movement and occurs from the region of higher concentration of the substance to that of its lower concentration.

cancerous growths are clonal in origin because cancer cells . multiple choice question. can invade healthy tissues originate fro
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
