The correct option is A.
Scientists had discovered that some animals, such as Elysia chlorotica has the capacity to photosynthesize. The animal usually incorporate chloroplast into its cell from the algae which it feeds on. The chloroplast enable it to make proteins which are essential for photosynthesis.

The right answer is A. Some carry out photosynthesis...

The sea slug, Elysia chlorotica, is the first discovered animal able to use photosynthesis to produce energy. This photosynthesis is performed by the chloroplasts of its main food source, the seaweed Vaucheria litorea. They are sequestered by the digestive epithelium of the slug for several months according to a phenomenon of kleptoplasty, continuing their function of carrying out photosynthesis.

However, the chloroplasts of Vaucheria litorea have transferred a large part of their genes required for photosynthesis to the nucleus of the cells of this alga during evolution. Photosynthesis is nevertheless maintained in the sea slug thanks to the transfer of a gene necessary for photosynthesis from the kernel of the seaweed to the genotype of the slug.

The amygdala is most used in times of fear, as well as for olfactory processing such as smell and pheromones, and emotional memory storage. It is located within the temporal lobes of the brain, where it receives sensory input and send signals to various parts of the brain including hypothalamus, the trigeminal nerve, and the ventral tegmental area.

In which of the following ways is DNA replication different from DNA transcription? (4 points)

Margarita [4]

Answer:

<h3>Transcription copies the DNA into RNA, while replication makes another copy of DNA. Both processes involve the generation of a new molecule of nucleic acids, either DNA or RNA; however, the function of each process is very different, with one involved in gene expression and the other involved in cell division.</h3>

Explanation:

So,my answer is,transcription happens outside the nucleus,and replication happens inside the nucleus.

mote1985 [20]

Answer:

Explanation:

This is a stroke and the site of injury is the left side of the brain, this occur when the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes.

A stroke occurs if their sudden bleeding in the left side of the brain, the right of the body will be affected, producing some of the following: numbness and weakness of the right arm and leg Speech problems (inability to form words). Amongst other symptoms.

The left side of the brain is responsible for controlling the right side of the body.

Stroke may occurs at any age and strock risk increase with age

How does a lyric virus kill the cells that it infects

Aleksandr [31]

Answer:

This may help!

Explanation:

In the lytic cycle, a phage acts like a typical virus: it hijacks its host cell and uses the cell's resources to make lots of new phages, causing the cell to lyse (burst) and die in the process. Entry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium.

This substitution score matrix called _____ is derived from protein families that are characterized by blocks of conserved amino

Naily [24]

Answer:

BLOSUM

Explanation:

A substitution matrix is a matrix used in bioinformatics (and also in computational biology) to determine/estimate the rate at which one character -which is specified by a nucleotide sequence in nucleic acid alignments or by one amino acid in protein alignments-, changed to another character during the course of the evolution. The BLOcks SUbstitution Matrix (popularly known as BLOSUM) is a substitution matrix used to score one amino acid for another in a protein alignment. The BLOSUM substitution matrix is particularly useful to compare evolutionarily conserved regions between protein sequences and thus score their alignments, where each entry is indicated by a similarity score between two amino acids.
