Answer:
The correct answer is - 12%
Explanation:
Given:
Mean of the population - 0.52
Narrow sense heritability or h^2 - 0.6
The expected response of selection or R = ?
Solution:
The average oil content in the selected individuals - 0.7, 0.71, 0.72, 0.73, 0.74
And, the mean of these selected individuals = (0.7 + 0.71 + 0.72 + 0.73 + 0.74) / 5
= 0.72
Formula:
S = Average of selected individuals - Average of population
= 0.72 - 0.52
= 0.20
R = h^2 x S
R = 0.6 x 0.2
= 0.12
= 12%
Thus, the correct answer is - 12%

What is the result of a mutation during meiosis
Answer:
There's a change in the DNA sequence
Explanation:
If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population. Mutations are the sole source of genetic variability that can occur in asexual reproduction. But the effects of mutations can vary widely, from being beneficial, to having no effect, to having lethal consequences, and every possibility in between.

Give the common name of a eukaryotic microbe that is unicellular, walled, nonphotosynthetic, nonmotile, and bud-forming.
Answer:
Yeast
Explanation:
The correct answer would be yeast.
Yeast belongs to the fungi kingdom. Organisms in the fungi kingdom are generally eukaryotic in that their cells contain a nucleus and membrane-bound organelles such as mitochondrion. Fungal cells lack chlorophyll and are therefore nonphotosynthetic. They are also nonmotile
While fungi exhibit different body forms in terms of body complexity, the only unicellular form is yeast. The organism possesses all the attributes of fungi highlighted above, has a cell wall made largely of chitin, and reproduces through budding.
Answer: Yeast.
Explanation:
Yeasts are eukaryotic organisms, more precisely microscopic fungi that do not form filamentous networks (hyphae), classified as ascomycetes or basidiomycetes and are predominantly unicellular in their life cycle. The cell wall of yeasts is composed of complex "B"-glucan polysaccharides, mannoproteins and chitin. Also, yeast are non-motile organisms when they grownon a solid media.
They usually reproduce asexually by budding or bipartition and by having sexual stages that are not attached to a sporocarp (fruiting body). During asexual reproduction, a new bud emerges from the mother yeast when suitable conditions are met, after which the bud separates from the mother upon reaching adult size. In the case that they reproduce sexually, this occurs by means of ascospores or basidiospores. In conditions of nutrient scarcity, yeasts that are able to reproduce sexually will form ascospores.
Yeasts are important because of their ability to carry out the decomposition by fermentation (predominantly alcoholic) of various organic compounds, mainly sugars or carbohydrates, producing different substances. Therefore, they do not photosynthesize to obtain energy, since they do not possess chlorophyll (pigment responsible for capturing solar energy for photosynthesis).

At her initial evaluation, Ms. Jones reports that she has lost 25 pounds over the past eight months despite an increase in her appetite. She complains of extreme fatigue, heart palpitations and irritability. Clinical observations reveal a protrusion of the eyeballs and hand tremors. You suspect that she might have:
a. hypothyroidism
b. diabetes mellitus
c. hypopituitarism
d. hyperthyroidism
Answer:
d. hyperthyroidism
Explanation:
Hyperthyroidism is a condition that occurs when the thyroid gland in our body secretes too much of the thyroxin hormone. Thyroid gland is a butterfly shaped gland that is located in our neck and it produces the hormone called thyroxin. Excess production of thyroxin leads to a condition named hyperthyroidism.
A person's metabolism increases when he or she is suffering from hyperthyroidism. One's weight is lost but the appetite increases. Other symptoms are extreme fatigue, irritability, heart palpitations, sweating and puffy eyes.
Thus in the context, Ms. Jones is suspect to have hyperthyroidism as she she is showing all the above symptoms.

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.
Answer:
This question is incomplete as it lacks statements, the statements and the answers are as follows:
occurs in organisms that sexually reproduce - MEIOSIS
occurs during growth and development - MITOSIS
the DNA is replicated - MITOSIS AND MEIOSIS
occurs in all organisms - MITOSIS
the number of chromosomes remains the same - MITOSIS
the number of chromosomes reduces by half - MEIOSIS
Explanation:
Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.
The following are characteristics of the two division processes based on this question:
MITOSIS:
- It occurs during growth and development of an organism.
- it involves DNA replication
- it occurs in all organisms since every living organism undergoes growth and development.
- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n
MEIOSIS:
- It occurs only in organisms that sexually reproduce.
- it also involves the replication of DNA
- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.
High altitude adaptation is a complex physiological process that involves an increase in both the number of Hb molecules per erythrocyte and the total number of erythrocytes. It normally requires several weeks to complete. However, even after one day at high altitude, there is a significant degree of adaptation. This effect results from a rapid increase in the erythrocyte BPG concentration.
a. Try to do this without looking at the graphs. If oxygen-binding curves for both high altitude adapted hemoglobin and normal, unadapted Hb were plotted together, would the curve for high altitude adapted Hb be to the left of, to the right of or the same as the curve for unadapted Hb? Explain.
b. Is the oxygen binding affinity of high-altitude adapted Hb higher, lower, or the same as that of unadapted Hb? Explain.
Answer:
a. To the right
b. higher
Explanation:
From the information given:
a.
The oxygen-adsorption curve of the elevated high altitude modified the hemoglobin and this will move to the right because there is a reduced amount of oxygen available at high altitude, as well as an increase in carbon dioxide and H+ ion concentration, temperature, and all of which raise pH and shifts the curve towards the right.
b.
As there is a low relative partial pressure of oxygen at high altitude, the oxygen-binding attraction of high altitude adaptable hemoglobin is greater and higher than that of unadapted hemoglobin under pulmonary oxygen loading. This is important to optimize the oxygen concentration levels in blood circulation and blood tissues.

Consider the spread of the following emerging infectious diseases, using the chain of infection: E. coli O157:H7, Lyme disease, Ebola virus, hantavirus, influenza, tuberculosis, vCJD. For each disease, explain how the chain of infection can be interrupted?
Answer:
If one link is stop working.
Explanation:
There are six points at which the chain of infection can be broken or interrupted and a germ can be stopped from infecting another people. The six links are the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. If one of the link is broken or interrupted, no infection occurs in the body of an individual because all the links are attached to each other in the form of chain which can stop working if one of it stop working.
