Which modification is crucial in preparing an mRNA strand for proper translation? removal of introns and the splicing together of exons joining of ribosomal subunits to form a ribosomal complex removal of exons and the splicing together of introns addition of a poly-A tail addition of a poly-U tail

Answers

Answer 1

Answer: Removal of introns and the splicing together of exons.

Introns are regions of the DNA code that do not code for amino acids; therefore, they need to be removed before the mRNA strand is translated. Exons are the parts of the strand that do code for proteins, so they need to be pieced together once the introns are removed.

As a result of the absence of plants in the meadow, the rabbit population will probably

Answers

are there any multiple choices?
anyways, without the multiple choices, the answer will probably be; decrease.
Explanation: a meadow is a field or pasture; a piece of land covered or cultivated with grass, usually near a river.
Rabbits need lots of water and vegetables, so a meadow is usually the best habitat for them.
When the meadow is ruined (plants decrease), their habitat is ruined, causing them (the rabbits) to slowly decrease.
They could decrease as a result of their death, as a result of their migration to a different and more suitable place, or as a result of both. Usually, though, it is both, since when animals start to die, their species start to move away from that location.
hope this helped! brainliest? pls! :)

What does the right hemisphere of the brain control?

Answers

Answer:

The right hemisphere controls the left side of the body and our creativity.

Explanation:

The right hemisphere coordinates the left side of the body, and performs tasks that have do with creativity and the arts.

The left side of the brain is responsible for controlling the right side of the body and controls the way we think logically.

Final answer:

The right hemisphere of the brain primarily controls the left side of the body and is often associated with spatial and nonverbal reasoning. It's important to note, however, that the brain functions as a whole unit and most functions are distributed globally around the cerebrum.

Explanation:

The right hemisphere of the brain primarily controls the left side of the body. It plays a significant role in spatial and nonverbal reasoning, arousal, negative emotions, and pitch perception. Language processing, a task typically associated with the left hemisphere, can cross over to the right hemisphere via the corpus callosum, which bridges the two hemispheres together.

While the left hemisphere tends to be dominant in language functions in about 95% of the population, it must be noted that the brain functions as a whole and most of its functions are globally distributed. Misconceptions of people being 'right-brained' or 'left-brained' oversimplify the complex nature of the cerebral hemispheres.

In certain cases of intractable epilepsy, the corpus callosum is surgically severed as a treatment option, resulting in 'split-brain' patients. These patients highlight the roles of the individual hemispheres as we observe their behaviors and abilities post-surgery.
