Most sperm cells die in the vagina when entering the female's body because Most sperm cells die in the vagina when entering the
taurus [48]

Answer:

of the low pH of the vagina.

Explanation:

The pH of the vagina is maintained at highly acidic levels to prevent the germ buildup. The range of vaginal pH is around 3.8 to 4.5. The very low pH of the vagina creates a hostile environment for sperms and most of the sperms are killed as they enter the vagina due to the acidic pH.

Apart from supplementing the sperms with energy, cervical mucus serves to protect the sperms from the hostile conditions of the vagina. The cervical mucus has an alkaline pH at or near the ovulation to protect sperms from acidic pH of the vagina and to facilitate fertilization.

If round seeds is dominant to wrinkled seeds in peas, what type of stem will the offspring of a round seed plant and a wrinkled
Phoenix [80]

Since the round seed gene is the dominant gene, it follows that, a cross between  a round seed plant and a wrinkled seed plant will lead to only round seed offspring.

<h3>What is genetics?</h3>

Genetics is the science that studies the patterns of inheritance. The unit of inheritance located in the chromosome is called the gene.

Since the gene for having round seeds is dominant over the gene for having wrinkeled seeds, a cross between  a round seed plant and a wrinkled seed plant will lead to only round seed offspring.

Describe the steps in transcription that require complementary base pairing.
nalin [4]

Answer:

Explanation:

Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.

During transcription, the code present in DNA gets transcribed into the code in mRNA.  (messenger RNA)

RNA even though is a single stranded shows base pairing.

The pre-mRNA gets created from the DNA.

DNA has two strands, one of these strands acts as coding and another non coding strand.

The DNA shows base pairing with AGTC.   [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]

Whereas mRNA base pairing with AGUC.  [ U- Uracil ]

Here in mRNA, instead of thymine, uracil gets paired.

According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.

The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.

The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
