Explanation:
Huntington's disease is an autosomal dominant trait. Given the pedigree below, if individual IV-4 has three children with a normal woman, what is probability that they would have at least one child with the disorder
Answer:
The answer to the given question is =7/8
Explanation:
In autosomal dominant traits, one copy of the affected gene is enough to cause the disease. Let ’A’ be the affected gene, ‘a’ be the non affected gene. Since IV-4’s parents are a couple of affected and non-affected. So, he has the genes Aa, i.e. a single affected gene.
A a
a aA aa
a aA aa
Number of children affected=[tex]\frac{1}{2}[/tex]
Number child affected out of three = [tex](\frac {1}{2}) ^{3}[/tex]
At least one child affected out of three = 1-P (number of children affected out of 3 )
= [tex]1-(1/2)^{3}[/tex]
= [tex]\frac{7}{8}[/tex]
So, the answer to the given question is 7/8

g You have made a transgene that expresses green fluorescent protein (GFP) in spermatogonia only. If you are examining a transverse section of the testes where would you expect to find GFP positive (GFP) cells
Answer:
The correct answer is - Associated with the Sertoli cells in the seminiferous tubule.
Explanation:
Interstitial cells are found between seminiferous tubules and Each spermatogonial cell undergoes the process of spermatogenesis process and produces sperms in the lumen of seminiferous tubules.
This could be possible only due to GFP gene expresses only in spermatogonia, we can expect to find GFP + cells associated with the Sertoli cells in the seminiferous tubules.
Therefore, Spermatogonia are associated with Sertoli cells in the seminiferous tubules of the testis.
One of the distinguishing characteristics of nervous tissue is how difficult it is to repair damage to nervous tissue. Explain factors limit neurogenesis in the CNS of adults, why is it so hard to repair a damaged nerve
Answer:
Inhibitory influences from neuroglia, and the absence of growth-stimulating cues.
Explanation:
Neurogenesis in adults is limited by Inhibitory influences from neuroglia, mainly from oligodendrocytes, and the absence of growth-stimulating cues that are present during fetal development. It is so hard to repair a damaged nerve because nerve cell like other cells can't divide and increase in number, they can't renew themselves. Due to no division, the nerve cells does not increase in number and therefore can't repair themselves.

- Roots are the only organs in a plant that need water.?
Answer:
No
Explanation:
But they are the only part of plants that absorb water
No roots are not the only organs in a plant that needs water.
What are roots of plant?
Roots are organs of higher plants that absorbs water and mineral ions from soil. Two main type of root system is observed in plants: Tap root system and Fibrous root system. Tap root systems are found in dicotyledonous angiosperms (such as pea) and gymnosperms (such as pine) whereas Fibrous root system is mostly observed monocotyledonous angiosperms (such as wheat or rice).
The three main primary function of the roots are:
1. They anchor the plant to the soil.
2. Absorb water and mineral ions from the soil to be later used by the plant.
3. It acts as food reserve.

2.Write two differences between the nutrition in amoeba and human beings.
3.Fungus can be harmful and useful. Give an example showing both of these traits of fungus.
Answer:
Similarity:
Amoeba and human beings require the same nutrients like carbohydrates, proteins, and fats for their growth and survival.
Difference:
1. Mode of Nutrition:
Amoeba is unicellular and microscopic, which makes it an organism that uses the Holozoic mode of nutrition. It ingests food through its cell membrane and feeds on other tiny organisms like bacteria, algae, and protozoans. On the other hand, human beings are multicellular organisms and use saprophytic and holozoic modes of nutrition. They ingest complex food materials that are broken down into simpler nutrients.
Fred loves La Paz, Bolivia so much that he decides to stay there for a couple years. All of the following changes could be considered a compensatory mechanism in response to the chronically decreased oxygen content EXCEPT
a. an increase in amount of circulating red blood cells.
b. an increase in oxygen extraction by perfused cells.
c. an increase in hemoglobin’s affinity for oxygen.
d. a decrease in heart rate.
Answer:
d. a decrease in heart rate.
Explanation:
As the altitude rises, the number of oxygen molecules in the air decreases. Lower oxygen levels at high altitudes stimulate the release of erythropoietin (EPO), which is associated with the increased red blood cells, i.e., it enables more oxygen molecules to be transported to cells and tissues. Moreover, at high latitudes, the increased hemoglobin (Hb)–oxygen affinity helps to safeguard arterial O2 saturation and thus mitigates the effects of low oxygen concentration in arterial blood (arterial hypoxemia). Finally, oxygen extraction depends on an appropriate supply of oxygen in the blood vessels. An increased oxygen extraction occurs when there is an inadequate circulating blood volume or when the number of red blood cells decreases below the normal levels.
Which of these methods that aids in the movement of ions or molecules across a cell membrane requires the use of energy which is supplied by ATP molecules?A. Osmosis.B. Reverse diffusion.C. Passive transport.D. Active transport.E. Facilitated diffusion.
Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.

B. the increased expression of a particular trait when a hybrid species is formed.
C. the expression of one gene masking the effects of another gene.
D. quantitative traits that diminish or intensify a particular phenotype.
E. the influence of environment on the expression of a particular genotype.
Answer:
the influence of environment on the expression of a particular genotype.
Explanation:
In genetics, we define penetrance as the proportion of individuals in a given population carrying a particular gene/allele which leads to the expression of the particular trait associated with that gene/allele.
Expressivity is defined as the degree of expression of a given phenotype by individuals who possess a particular genotype. Expressivity shows the extent of variation in expression of genes by individuals having a particular genotype.
Both penetrance and expressivity has to do with the influence of environment on the expression of a particular genotype.
