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.
Which of the following mutations is NOT a point mutation? A. Silent mutation B. Nonsense mutation C. Missense mutation D. Insertion mutation
the answer is Insertion mutation :)
(search up "types of mutations")
Point mutation is the alteration of the single nucleotide base in the sequence. Insertion mutation is not a type of point mutation. Thus, option D is correct.
What is point mutation?A point mutation is a modification and change in the base of the genetic sequence. In this type of mutation, only a single nucleotide base is altered. Point mutations are categorized as transition mutations and transversion mutations.
Silent, Nonsense, and missense are the transversion type of point mutation. In this mutation, the purines get altered by pyrimidines and vice versa. On the other hand, insertion mutation is the frameshift mutation.
Therefore, insertion is not a type of point mutation.

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 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.

The Center for Disease Control and Prevention recommended that men infected with Zika virus delay planned pregnancies. What is the recommended length of time for delayed conception for men afflicted with Zika virus?
Answer:
This should be 6 months
Explanation:
Generally ZiKa disease is caused by Zika virus,It is transmitted by Aedes mosquito as vector.It symptoms(rashes,fever,joint pains) are mild in the first week,but very severe in pregnant women.Men who visited then endemic region are advised to delay intercourse for 3 months,while those who were infected were recommended to abstain from sex for 6 months,
This is because the virus has been found in the semen longer than other body fluids.it has been found in infected semen for 180 days after healing.
In infected pregnant women,this can be transmitted to the fetus,causing microcephaly in the unborn child,Protection against mosquito bites is best way of prevention.
In exposed lady the period of abstinence should be 2 months.
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.

4. nociceptors
Explanation:
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.

Which sustainable practice is paired correctly with its impact on the environment? Using bamboo results in an increased use of forest trees. Practicing contour plowing results in a need for more land. Setting irrigation systems to run longer results in a reduction of water use. Building more wind farms results in a reduction of fossil fuel use.
Hey there! I'm happy to help!
Using bamboo results in an increased use of forest trees. Bamboo is a grass, not a tree. I don't see how using more bamboo would increase your usage of trees. This option is incorrect.
Contour plowing is when your plow around the contour lines (which are basically like elevation lines) of a hill or slope. This actually reduces soil erosion and lasting effects of natural storms and disasters, so it does not result in a need for more land. This option is incorrect.
Setting irrigation systems to run longer results in a reduction of water use. Irrigation is a system of watering, so you need water for it. It would not reduce water use. This option is incorrect.
Building more wind farms results in a reduction of fossil fuel use. If you are getting your power from renewable resources like the wind or the sun, you will not need to use as many fossil fuels, and this would reduce their use. This option is correct.
Have a wonderful day!
The practices that aid in economic, human and ecological dynamism and health is called sustainable practices. This procedure helps in conservatively preserving the limited sources.
The correct pairing is:
Option D. Constructing more wind farms results in a decrease in fossil fuel usage.
The practices can be explained as:
Using too many bamboos will result in the degradation of lands and increased soil erosion. It will not affect the usage of other forest trees.The method of agriculture practice in which the ploughing is done near the contour lines is called contour ploughing and does not need much land also helps in reducing soil erosion and disasters.The irrigation system conserves water and is a beneficial technique of watering the agricultural lands with an efficient amount of water.Wind energy generates more energy and power which is a renewable source compared to fossil fuels and reduces the use of petrol, diesel and coal.Therefore, option D is correct.
