Which of the following is a disadvantage of using biopower?A. It requires mass production of crops.
B. It is readily available in most places.
C. It produces net-zero emissions.
D. It is biodegradable

Answers

Answer:

A. It requires mass production of crops.

Explanation:

Of all the options the only one that represents a disadvantage is that biopower requires mass production of crops because it could cause loss of biodiversity, degradation of soil quality, soil erosion, food toxicity (due to pesticide residues) and pollution ( use of fossil fuels for agrichemical manufacture, farm machinery and long-distance distribution).

The fact that it is readily available in most places, produces net-zero emissions and is biodegradable are all advantages.

I hope you find this information useful and interesting! Good luck!

Explanation:

A genetics researcher finds that a form of human albinism in a certain population is controlled by the recessive allele, a, for the absence of skin pigment and the completely dominant allele, A, for presence of skin pigment. If the recessive allele occurs in 30% of this population, what percent of the population has skin pigment but also carries the recessive allele?21 percent
42 percent
91 percent
51 percent

Answers

Answer:

Option A

Percent of the population that has skin pigment but also carries the recessive allele is $21\n$ percent

Explanation:

As per hardy-weinberg equation,

$p^2+q^2+2pq = 1\n$ ------------- Eq(A)

where

$p^2= \n$ frequency of the homozygous genotype (dominant)

$q^2= \n$ frequency of the homozygous genotype (recessive)

$pq= \n$ frequency of the heterozygous genotype (recessive)

Also, sum of the allele frequencies at the locus is equal to one.

Thus, $p + q = 1\n$ ------------- Eq(B)

Here frequency of recessive allele i.e $q = 30\n$ %

Substituting this in equation B, we get

$p + 0.3 = 1\np = 1-0.3\np= 0.7\n$

frequency of dominant allele i.e $q = 70\n$ %

Substituting the value of frequency of both dominant and recessive allele in equation A, we get

$(0.3^2) + (0.7^2) + 2pq = 1\npq = (1-0.3^2-0.7^2)/(2) \npq = (0.42)/(2) \npq = 0.21\n$

Thus, percent of the population that has skin pigment but also carries the recessive allele is $21\n$ percent

The correct answer will be 42%

The majority of the protein inside a red blood cell (erythrocyte) is:a. albumin
b. hemoglobin
c. fibrinogen
d. immunoglobulin
e. porphyrin

Answers

Answer: Hemoglobin

Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.

When cells respond to an extra cellular signal , they convert the incoming information from one form to another. This process is called signal a. induction
b. interference
c. transduction
d. transformation

Answers

Answer:

The process is called signal transduction

Explanation:

Signal transduction entails the binding of a ligand or extracellular signal to a receptor and this gives rise to a biochemical cascade of reactions, interactions forming networks and this elicit cellular responses. These responses may include, post translational modifications, changes in gene transcription and translation.

Answer:

The process is called signal transduction.

Explanation:

Signal transduction is the process by which chemical or physical signal is transfered from outside of the cell to the interior of the cell thereby transforming the information from one form to another form to ensure adequate response. Signal transduction depend on receptors protein.

There are three stages of signal transduction and they are;

1. Receptor or protein present at the cell surface detect signals.

2. Transduction, change in receptors enhance changes in the cell.

3. Response, the cell respond to the signal.
