Explanation:
Alternative splicing of RNA produces many mRNA strands from primary RNA transcript. When alternative splicing of RNA occurs, all the introns and some exons are removed. The removal of these exons produces different mRNA strands which are then translated into diffident kinds of proteins. Alternative splicing of RNA can highly increase the number of new produced proteins from same gene.
Answer: it is where cellular respiration occurs
Explanation:
Answer:
deuterostomes
Explanation:
During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.
Semen creates a(n)<u>alkaline </u>environment for sperm to safely travel through both the male and female reproductive tracts.
In the field of biology, semen can be described as a white, slippery fluid that is released from the male reproductory organ. Semen is also referred to as the seminal fluid.
The semen of males carries the sperm cells which are required for the fertilization of the female egg. The conditions should be favorable for the process of fertilization to occur.
The natural atmosphere of the vagina of a female is acidic in nature. The sperms need a neutral environment for survival. Hence, the semen is produced alkaline in nature to prolong the lifetime of sperm cells. The alkalinity of the semen neutralizes the acidity of the vagina.
