Answer:

c. specialised cells

Explanation:

Sponges are invertebrates that belong to phylum Porifera. Most of them live in marine environment. They do not have true tissues or organs but specialised cells that perform specific functions for example porocytes, amoebocytes, pinacocytes and choanocytes. Porocytes control the water amount entering inside the sponge pores and choanocytes control the water movement inside the sponge body.

Sponges consume food via phagocytosis. They reproduce both asexually and sexually. They are sessile i.e. immobile.

How does polygenic inheritance differ from mendelian inheritance
Luba_88 [7]

Answer:

Mainly, the number of genes that control traits.

Explanation:

Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.

Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.

Mendelian inheritance would assume that the offspring would either be fair or dark only.

Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.

Hope you understood it.
