Answer:

The correct answer is C. the size of the algae population .

Explanation:

An ecosystem is made up of biotic and abiotic factors. Biotic factors are the living components of an ecosystem that impact the ecosystem and abiotic factors are the non- living components that have their own impact on the ecosystem.

So according to the definition of biotic factor algae is the biotic factor in this question because algae is a living component of the ecosystem that influences the ecosystem by providing food to the corals.  

So by providing food algae supports the coral's ecosystem and coral provides a home to algae to grow. In the ecosystem, both biotic and abiotic factors interact with each other.

So the correct answer is C. the size of the algae population.

The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.

A) The Dura mater

B) The arachnoid mater

C) The pia mater

The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.

The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.

The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.

tatiyna

Answer:

The correct answer will be- Non-Mendelian inheritance (incomplete dominance)

Explanation:

Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.

In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.

Cross

RR (red) x rr (white) = Rr (pink)

Thus, incomplete dominance is the correct answer.
