Answer:
d. Simple Columnar Epithelia
Explanation:
The simple columnar epithelium is an epithelial tissue that has a single layer of nonciliated cells. The cells look like columns and have oval nuclei near their base. This type of epithelial tissue has microvilli at the apical surface of their columnar epithelial cells. These microvilli are the fingerlike cytoplasmic projections that serve to increase the surface area for absorption.
Simple columnar epithelium makes the linings of the gastrointestinal tract, specifically from the stomach to anus where they live the cavities of these organs.
Answer:
The correct answer is - a reduced expression of alpha, beta, and omega subunits of RNA polymerase.
Explanation:
Sigma subunit of RNA polymerase is the subunit that the holoenzyme, the other part of the enzyme, identifies and attaches with the specific DNA site called promotors that is responsible for coding the alpha, beta, and omega subunits of this enzyme.
As it is given that there is a deletion in the sigma subunit due to mutation that results in decreased the sigma factor's binding affinity to the promoter region. That ultimately leads to less or unable to bind properly to the promoter and the level of gene expression to fall or be reduced.
Let's work this out with a punnett square:
So if we have a white eye female and this trait is sex-linked, what will be her genotype?
Since the male is red-eyed and this trait is sex-linked, what will be his genotype?
After that, we can set up the punnett square together
Answer;
Deep fascia
Explanation;
-Deep fascia is a layer of dense connective tissue which can surround individual muscles, and also surround groups of muscles to separate into fascial compartments.
-It is a dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the body. It is in the form of a fibrous sheet which invests the body beneath the superficial fascia.
