Semen creates a(n)__________ environment for sperm to safely travel through both the male and female reproductive tracts.
Assoli18 [71]

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.

You are given two true-breeding groups of rabbits. The first group has floppy ears and white coat color. The second group has st
malfutka [58]

Answer:

Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance

Explanation:

Let the allele for floppy ears be "F" and the allele for straight ears be "f"

And Let the allele for black coat color be "B" and the color for white coat color be "b"

Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)

The 16 offspring have genotype FfBb

Phenotype of 16 offspring is Floppy ears and grey coat

Ff represents the floppy ear , thus "F" is dominant over "f"

Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.

Hence, option E is correct

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Alina [70]

Answer:

I so I am also a bit confused, but I hope this could answer your question!

Explanation:

The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine.  The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.

The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.

This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.
