In a flock of sheep there are animals with brown fleece and brown eyes and others with white fleece and blue eyes. There are no animals with white fleece and brown eyes or with brown fleece and blue eyes. What can you conclude about the genes for fleece color and eye color
Answer:
In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby's eye color is determined by the parents' eye color and whether the parents' genes are dominant genes or recessive genes.
A lamb inherits 2 genes for color, one from each parent. This color gene causes the pigment named eumelanin to be produced in the cells of the wool follicles. This pigment produces the basic black or brown color of the Icelandic sheep.

Explanation:
If 30% of the bases in a particular DNA molecule are guanine (G), what percentage of the bases would be thymine (T)? Explain your reasoning.
Answer:
20%
Explanation:
There are four bases in DNA: guanine (G), cytosine (C), adenine (A), and thymine (T). They all have to add up to 100%. In DNA, guanine pairs with cytosine and adenine pairs with thymine.
If guanine is 30%, cytosine is also 30%.
30% + 30% = 60%
Now subtract from 100%.
100% - 60% = 40%
Thymine and Adenine make up 40% of the DNA. Now divide by 2 since there are two nitrogenous bases.
40% ÷ 2 = 20%
Guanine is 30%, Cytosine is 30%, Adenine is 20%, and Thymine is 20% for a total of 100% of the DNA.

Which of the following statements are true? Multiple Choice Muscles work in antagonistic pairs because if one muscle pushes during contraction, the opposing muscle across the joint must pull. Muscles work in antagonistic pairs because muscles lengthen during contraction. Muscles work in antagonistic pairs because tendons lengthen during contraction. Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax.
Answer
if one muscle shorten during contraction the opposing muscle across the joint must relax
The true statement among the statements above is that Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax.
For better understanding, we have to know why muscle works in antagonistic pair and the reason for this pairing.
As the name implies, Antagonistic pairs is when muscles are set down or grouped in pairs. that is when a muscle tightens or shortens (contrast) and pulls, the other muscle will then be in a relaxed state so as to allow movement.
There is a great need or importance for antagonistic pairs in muscles. That is Muscles do perform its role in an antagonistic pairs because they can only reduce (shorten)making or taking the movement in one direction. There is also the need for another muscle that shortens in order to lead/make movement go in the opposite direction.
Example of this antagonistic muscle pairs is commonly found in insects where their exoskeleton in the hind leg of the insect gives room for the muscles to work in antagonistic pairs, also the tibia flexes and others.
therefore, we can conclusively say that the statement that Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax is true.

A person cannot produce several types of proteases. Name the problem this specific person probably has and explain why.
Answer:
The person have excess amount of proteases and when this happen, the person will protein breakdown in the body or lack of protein in the body which can affect most of the organs in the body.
Explanation:
Under normal conditions in the body, blood and body tissues have a specific potent enzyme called proteases. Protease help in the breakdown of protein in the body and play important roles in defending or fight against incoming infections and inflammatory processes in the body .There is need for thslese proteases to be regulated or control because overactivity can lead to protein destruction which will lead damage of different body organs. In order to control this, blood and other tissues in the body posses enzymes with protease inhibitory activity, these enzymes help to prevent its from undergoing excessive action and potentially harmful effects.

A diploid human cell normally has 23 pairs of homologous chromosomes, but as a woman ages, the chances of nondisjunction increase. Imagine that a gamete is produced that received two copies of chromosome 21 due to nondisjunction during meiosis II. If the gamete is fertilized with a normal sperm, the embryo's cells will contain _______ chromosomes.
47 chromosomes instead of 46 because there are 3 chromosomes in pair 21. This is called Down syndrome, described most recently by Lejune in 1958
If the gamete is fertilized with a normal sperm, the embryo's cells will contain 47 chromosomes. The correct option is B.
What is nondisjunction?Nondisjunction refers to the phenomenon of unequal separation in meiosis.
If a haploid gamete has a missing chromosome due to nondisjunction, the diploid zygote it forms with another gamete will have only one copy of that chromosome from the other parent, a condition known as monosomy.
Nondisjunction occurs when the separation fails, causing both sister chromatids or homologous chromosomes to be drawn to one pole of the cell.
Mitotic nondisjunction can occur when topoisomerase II, condensin, or separase are inactivated.
Because pair 21 contains three chromosomes, there are 47 chromosomes rather than 46.
Thus, the correct option is B.

Merkel cells are epithelial cells found around hair follicles which are capable of sensing gentle touch sensations such as, for example, tactile discrimination and environmental exploration. Tactile corpuscles are a class of nerve ending required for mediating sensitivity to light touch sensations. The lamellar corpuscles are another class of nerve ending capable of sensing deep touch sensations and vibrations. Finally, nociceptors are somatic sensory receptors capable of sensing noxious (damaging) stimuli.
1. Light-touch receptor located at the epidermal-dermal border: Tactile corpuscles (D)
Light-touch sensors called tactile corpuscles, sometimes referred to as Meissner's corpuscles, are situated near the epidermal-dermal boundary. They are located in the papillary layer of the dermis's dermal papillae, which are tiny, finger-like projections.
Particularly dense populations of tactile corpuscles can be seen in skin regions like the lips, palms, and fingertips that are sensitive to gentle touch.
