In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What is the frequency of individuals that are homozygous for this allele?.
Here, given-
homozygous alleles 'a' have a frequency of 0.3.
Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.
The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.
Calculation-
[tex]p + q= 1\\0.3 + q= 1\\q= 1- 0.3\\q= 0.7\\[/tex]
Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-
[tex]p^{2} + 2pq + q^{2} = 1\\Here,\\p^{2}= dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2}= recessive homozygous frequency\\[/tex]
Thus, the individuals homozygous for the allele can be calculated by-
[tex]q^{2} = (0.7)^{2} \\q^{2}= 0.49[/tex]

The correct sequence for the phases of the human cell cycle, starting with a newly divided cell, is?
Starting with a newly divided cell, the correct sequence for the human cell cycle phases are interphase followed by mitosis and then cytokinesis.
Interphase of the cell cycle does not involve any cell division. It is a period of growth and replication of the nuclear DNA. The cell prepares for the division in this stage. Interphase is further divided into the G1, S and G2 phases. Mitosis is the next phase of the cell cycle which involves the division of the cell in order to form daughter cells. Mitosis is further divided into the prophase, metaphase, anaphase and the telophase. Cytokinesis marks the end of the mitosis and this is where the cell actually separates to produce two daughter cells.

What type of trait in mendel's studies could vanish in one generation and reappear in the next generation?
Recessive traits often seem to disappear because two recessive alleles are needed to produce the recessive phenotype. They can skip a generation and then reappear if an individual inherits two copies of the recessive gene. Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations.
Recessive traits disappear because recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools and natural selection can only see the phenotype, not the genotype. While harmful recessive alleles will be selected against and it's almost impossible for recessive alleles to completely disappear from a gene pool.

The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.
What is antibiotic?Antibiotics from the key class of glycopeptides can stop this process. Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate. The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.
