Answer:

1-Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli.

2-They also don't reproduce independently but must replicate by invading living cells.

Viruses are considered non living since they are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy.

If the frequency of an allele is 0.75, how many copies of this allele should be in a population of 300 diploid individuals?
Ray Of Light [21]

I have provided the options below:

a. 150

b. 225

c. 300

d. 450

e. 75

Answer:

150

Explanation:

Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.

Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2

Allelic frequency = 0.75.

Therefore, the percentage of the allele in the population would be given by

0.75^2 = 0.5625 = 56%.

And the total number of individuals with this allele in the population:

number of individuals = 56×300÷100

= 168 or

150 nearest figure.

Polydactyly is an autosomal dominant trait in which affected individuals have more than five fingers and/or toes. If a pedigree
bija089 [108]

Answer:

Reduced penetrance or incomplete penetrance

Explanation:

Penetrance refers to the extend which a certain gene or set of genes is expressed in a population.

It can be complete where there is expression of the gene in a population having it.

Whereas, in reduced penetrance is where the mutation is not expressed in every individual in the population having it.

For instance polydactyly exhibits reduced penetrance since the parents had the mutation it was not expressed it came to be expressed on their pedigree.

The binding of a compound to an enzyme is observed to slow down or stop the rate of the reaction catalyzed by the enzyme. Increa
Setler79 [48]

Answer:

The correct answer is A the compound is a competitive inhibitor

Explanation:

Competitive inhibitor competes with the substrate to bind to the active site of the target enzyme and after binding to the active site the inhibitor slow down or stop the reaction catalyzed by that enzyme.

          Competitive inhibitor basically effects the Km value of the enzyme thus decreasing the activity of the later.

           Increasing the substrate concentration displace the inhibitor from the enzyme"s active site thus reducing the inhibitory effects of the later thus increasing the activity of the enzyme.

Erythrocytes do not carry out aerobic respiration; thus, they do not consume any of the oxygen they are transporting.
photoshop1234 [79]
False
Erythrocytes also known as Red Blood cells carry oit aerobic respiration; thus, they consume any of the oxygen they are transporting. They transport oxygen and takes away carbon dioxide from the cells. It contains a pigment called haemoglobin that helps in this process......
