The outer layer of the onion cell, which is a plant cell, contains cellulose, however, the human skin cell (which is an animal cell) does not contain cellulose in it. The plant cells have a rigid cell wall present around the cell membrane, which protects the cell from the outer environment and keeps it rigid. This cell wall of the plant cells is composed of the cellulose. The animal cells have no cell wall present around them, and thus, contain no cellulose.

Hence, the correct answer is 'it contains cellulose'.

What are the chances that a kitten born would have a DIFFERENT genotype than the sister's cat Moo?
Strike441 [17]

A kitten born will have genotype different from sister because the concentration of gene expressed is different in all kittens as it is a phenomenon of codominance.

Explanation:

The moo cat is black and white bicolour cat.

The cat has white colour fur which is combined with some other colour as black.

White colour in cat has white spotting gene that prevents the patches over cat's body.

SS genotype results in large concentration of white colour.

Ss results in medium concentration of white colour.

ss results in black or other dark colurs with very meager or no white colour on skin.

The resultant colour appearance of skin in cats is due to codominance. The colour of the skin depends on the concentration of gene and protein expressed. So, the sister moo cats can have diffrent genotype and different level of white colour patches on the skin and genotype of SS,Ss or ss can be there in sister kittens.

Discuss the ecological importance of the dark phase​
Sergio [31]

Answer:

In the dark phase (which takes place in the stroma), the ribulose bisphosphate added to the carbon dioxide gas (CO2) in the air results in the production of organic compounds, principally carbohydrates or sugars, whose molecules contain carbon, hydrogen, and oxygen.
