Given what we know, we can confirm that Ostia are important to sponges because they pull water into the sponge through the beating of their flagella.

<h3>What are Sponges?</h3>

A sponge is an aquatic multicellular organism.
Morphologically, they are very simple organisms, lacking complex structures.
One structure that they do possess is the Ostia.
The Ostia are a series of pores located throughout the body of the sponge.
They serve to draw in water through the beating of multiple flagella.

Therefore, we can confirm that since the Ostia of the sponge are used to pull water into the sponge through the beating of their flagella, the correct answer would be option D.

Answer:

a. bottleneck effect.

Explanation:

A bottleneck effect occurs when some adverse environmental conditions such as typhoons and famine reduce the population size considerably. The allele frequencies of the population are changed. As the population grows again, the gene pool has different allele frequencies than the original population. During population growth, some harmful alleles may become more abundant resulting in a rare disease such as achromatopsia. Therefore, the given population represents the bottleneck effect.

How does light intensity affect the rate of photosynthesis?

Mazyrski [523]

If all other resources are in adequate supply, then the light intensity will increase the rate of photosynthesis. To balance it out, other things then usually start becoming short in supply, so things often don't change.

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.

Kruka [31]

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.
