Answer:

You do need to switch your answers.

Explanation:

In animal cells, the cell membrane pinches together in the middle of the cell to cut in half or divide the cytoplasm.

In plant cells, the cell wall of a plant cell is rigid, it does not pinch in like the more flexible cell membrane in animal cells. It has a structure called a cell plate that forms across the middle of the cell.

Hope this helps! Have a nice day!

Which molecule is the final electron acceptor for electrons from photosystem I? a. Oxygen b. Chlorophyll in photosystem II c. Ca
Mumz [18]

The molecule which is the final electron acceptor for electrons from photosystem I is (d) NADP⁺.

Photosystem I is the protein complex involved in the process of photosynthesis. It captures the light energy to mediate the transfer of electrons from a series of electron transporters. It is involved in non-cyclic as well as cyclic photophosphorylation.

NADP⁺ is the Nicotinamide Adenine Dinucleotide Phosphate. It acts as a coenzyme. It is an important constituent in various anabolic reactions like Calvin cycle, lipid and nucleic acid syntheses, etc. The oxidized form of NADP⁺ is NADPH. It is present in organisms of almost all kinds.

In guinea pigs coat color is determined by a single gene with two alleles. A guinea pig from a true-breeding black strain is mat
OLga [1]

Answer:

1/3 of black F2 progeny will be homozygous.

Explanation:

Here, BB = black coat color = true breeding dominant black strain

bb = white coat color =  true breeding recessive white strain

When true breeding black and white guinea pigs are mated to give F1 progeny:

BB X bb = Bb ( all black guinea pigs )

When two of the F1 guinea pigs are mated to give F2 progeny:

Bb X Bb = BB, Bb, Bb, bb

F2 progeny has 3/4 progeny as black (BB and Bb) . Out of them 1/3 are homozygous and 2/3 are heterozygous.

Hence, 1/3 of black F2 progeny will be homozygous.

Which structure has the least effect on the ability of a virus to infect and replicate in a host cell?
AleksAgata [21]
The answer is an envelope.

A virus is an infectious agent that can replicate only inside a host cell. When it is outside the cell, it consists of genetic material coated with protein capsid. Some viruses also have an envelope which covers capsid. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.
