The key evolutionary development of animals seen for the first time in sponges is that of  Multicellularity.
Multicellularity means having or consisting of many cells or more than one cell to perform all vital functions. Sponge is a member of the phylum Porifera. It is a simple animal with any cells, but no mouth, muscles, heart or brain. It is any primitive multicellular aquatic animal that constitute the phylum stated above.

The key evolutionary development of animals seen for the first time in sponges is that of Multicellularity.    A Multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions.  Sponges do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system  supports all these functions.

AURORKA [14]

Answer:

Part A....B

Part B....C

Explanation:

It should be understood that Mice are always first used to clinical test especially for drugs or other things that are supposed to be for human use, this is because Mice and human genetic disorders have arisen from conserved and related evolutionary processes. Therefore, when the clinical trial or test produces a positive result in the Mice, it is almost certain that the result will be the same in human.

Now in part B. When the result result is different, it might be because of the differences in anatomy and physiology might hide or change development and symptoms of disease. And that is the reason why, the result of a particular drug differs from person to person.

Complete question: The chart shows the movement of a ball after several seconds.

Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?

a. Column A should be “Time,” and Column B should be “Position.”

b. Column A should be “Position,” and Column B should be “Time.”

c. Column A should be “Velocity,” and Column B should be “Speed.”

d. Column A should be “Speed,” and Column B should be “Velocity.”

Answer:

Column A should be "Time," and Column B should be  "Position"

Explanation:

In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.

Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".

Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.

Option C) and D) are not possible, as both of them are variables that depend on time.

Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.

Explanation:

The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.

The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.

MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.

The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.
