Answer:
Translation
Explanation:
Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.
The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.
Hence, according to this question, the process occuring at B according to this image is TRANSLATION.
<span>Only one sperm normally fuses
with an egg because if more than one sperm fuses, through a process
called polyspermy, development of the zygote usually stops.
</span>
<span>Fertilization of one egg by
two sperm is possible, but the resulting zygote is almost never viable
because such a zygote would have three sets of chromosomes instead of
the normal two. This condition, called triploidy, is usually
incompatible with life. Those rare triploid infants that do survive to
term have severe and multiple birth defects and rarely live more than a
few days. </span>
Answer: 1
Homeostasis in terms of temperature within the human body is achieved by reaction to stimulation from the environment. For example, in cold temperatures our bodies shiver to get warm.
