Nesterboy [21]3 years ago
5 0
Sponges have cellular-level organization, meaning that that their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues and bodies are a sort of loose aggregation of different kinds of cells. This is the simplest kind of cellular organization found among parazoans

Is the following statement true or false? Explain your
Marrrta [24]

Answer:

False.

Explanation:

Cell membrane is made of the lipids and proteins with the attached moieties of carbohydrates. The plasma membrane is the selectively permeable membrane that allows the diffusion of some selected particles only.

The transport along the cell membrane depends on the size and the hydrophobicity of the molecule. The size of oxygen is although higher than magnesium but to its highly hydrophobic nature it can easily pass through the plasma membrane as compared with the magnesium. The oxygen diffuses out faster than magnesium.

Thus, the answer is false.

nalin [4]

Answer:

A

Explanation:

From what I know this could be wrong, but in the four stages of natural selection, the first step is overproduction, the second step is adaptation, and the third step is competition or survival of the fittest. This means that only the organisms with the best adaptations for their surroundings will survive. COULD BE WRONG SORRY IF IT IS

Answer:

As a result of the Hershey and Chase experiments, scientists believe

that the “transforming principle” is DNA.

Explanation:

Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.
