Answer:

Basically, most   antibiotic drugs  are not  effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of  diameter of the  bacterial growth . <u>This is because the diameter   is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a  measure  of how effective  it  can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control  the bacteria, While  a large diameter is an indication of low effectiveness of the drug.

Based on this analogy, penicillin with wide usage for control  of bacteria growth  with  diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm  or 6mm depending on   type of bacterial.

Therefore, the least 3mm  diameter presented by penicillin is an indication that , antibiotic drugs  are not effective enough, and further research need to be done to control growth of bacteria and therefore its   pathogenic  effects.

If the frequency of the recessive allele for a gene is 0.3, calculate the expected frequency of heterozygotes in the next genera
Kisachek [45]
Q = recessive allele frequency = 0.3, and thus in H-W equilibrium there are ONLY two alleles, q (recessive) and
p (dominant). Therefore all of the p and q present for this gene in a population must account for 100% of this gene's alleles. And 100% = 1.00.
So p, the dominant allele frequency, must be equal to 1 - q --> p = 1 - q
p = 1 - 0.3 = 0.7.
Since heterozygotes are a combination of the p and q, we must again look at the frequencies of each genotype: p + q = 1, then (p+q)^2 = 1^2
So multiplying out (p+q)(p+q) = 1, we get: p^2+2pq+q^2 = 1 (all genotypes), where p^2 = frequency of homozygous dominant individuals, 2pq = frequency of heterozygous individuals, and q^2 = frequency of homozygous recessive individuals.
Therefore if the population is in H-W equilibrium, then the expected frequency of heterozygous individuals = 2pq = 2(0.7)(0.3)
2pq = 2(0.21) = 0.42, or 42% of the population.
Hope that helps you to understand how to solve population genetics problems!

6. what is the approximate weight in kd of the band that is unique to crab muscle protein and is not found in abundance in fish?
xenn [34]

75Kda is the approximate weight of the band that is unique to crab muscle protein and is not found in abundance in fish.

An incredibly complex, naturally occurring molecule known as a protein is made up of amino acid residues connected by peptide bonds. All living things contain proteins, which are the building blocks of numerous vital biological substances like enzymes, hormones, and antibodies.

Lack of protein can result in muscle mass loss, which reduces strength, makes it more difficult to maintain balance, and slows metabolism. When your cells don't receive enough oxygen, it can also cause anemia, which makes you exhausted.

While an excess of amino acids is often eliminated, an excess of protein is typically retained as fat. Over time, this may result in weight gain, especially if you try to boost your protein consumption while consuming too many calories.
