Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
a plant cell has a large centralised vacuole containing cell sap and has a cell wall and an animal cell contains centrioles while a plant cell does not. a plant cell contains chloroplast while an animal cell does not
The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
Answer: B. Linoleic acid
Explanation:
Linoleic acid is an essential fatty acid. It is a polyunsaturated fatty acid for humans. It is a colorless or white colored oil. It is typically insoluble in water. It cannot be found deficient in the human body as humans obtain it in the form of different kind of food items like vegetable oils, seeds, eggs, meat and nuts. Thus it is abundantly consumed in the diet.
