I Organisms can be dassified based on homology, which is shared characteristics inherited from a common ancestor. In the past, homologies were based on studies of anatomical structures and patterns of embryonic development. In more recent years, the use of molecular biology techniques has allowed homologies to be compared at the level of nucleotide sequences. Nucleotide sequence comparisons are possible because all organisms share which of the following?​

Answers

Answer 1

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.

Answers

Answer:

A

Explanation:

A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.

The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.

The correct option is A.

A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.

CELL:

Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism.

Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells.

Similar cells perform similar functions while dissimilar cells perform dissimilar functions.

Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.

Give SOME EXAMPLES OF NATURAL CYCLE CHECKPOINTS .

Answers

Answer:

For example, delays in mitosis are often ascribed to 'activation' of the mitotic checkpoint, a descriptor that fails to recognize that the checkpoint by definition is active as the cell starts mitosis. Conversely, the completion of mitosis in the presence of misaligned chromosomes is often automatically interpreted to indicate a defective checkpoint, even though in the absence of critical testing alternative interpretations are equally likely. In this article, we define the critical characteristics of checkpoints and illustrate how confusion generated by the inconsistent use of terminology may impede progress by fostering claims that mean very different things to different researchers. We will illustrate our points with examples from the checkpoint that controls progression through mitosis

Explanation:

Answer:

Below

Explanation:

G1 checkpoint, also known as the Start or restriction checkpoint or Major Checkpoint; the G2/M checkpoint; and the metaphase-to-anaphase transition, also known as the spindle checkpoint.
