A cell can only respond to signals from other cells, not from the physical environment. receptor activation. The ability of a specific tissue or organ to respond to the presence of a hormone is dependent on: the presence of the appropriate receptors on the cells of the target tissue or organ.

8_murik_8 [283]

Answer:

The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done

Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.

Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.

Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.

Which areas of the brain undergo major growth spurts during middle childhood?

djverab [1.8K]

sensory and motor areas undergo major growth spurts during middle childhood.

The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
The brain is driven by the motor system, which also drives sensory stimulation and feedback.
These abilities must advance and grow in order to support behavior and academic learning.
Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.
