in what ways can overpopulation be beneficial to differential reproductive success?
Answer:
Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.
Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

Which of the following is TRUE about alleles? Which of the following is TRUE about alleles? The phenotype of the individual will always indicate with certainty the alleles of the individual. An individual will only carry one version of an allele. Alleles come in two forms, the good form and the bad form. Individuals carry both forms of each allele. An allele is a variant form of a gene.
Answer:
An allele is a variant form of a gene.
The phenotype of the individual will always indicate with certainty the alleles of the individual
Explanation:
An allele is the alternate form of a gene example is allele A, allele a
While writing the genotype of an individual the allele is always seen, it usually written in pairs example is AA , Aa, aa, SS
The phenotype of an individual will reveal the allele such person have example is an individual with the sickle cell having allele s through the appearance of such individual one could know if such person posses the allele.

Describe the immediate effect of the neurotoxin on the number of action potentials in a postsynaptic neuron. Predict whether the maximum membrane potential of the postsynaptic neuron will increase, decrease, or stay the same.
Answer:
Inhibit control over ions.
Explanation:
The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

What are proteins?Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
Moreover, proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
Therefore, a molecule made up of amino acids. Proteins are needed for the body to function properly. They are the basis of body structures, such as skin and hair, and of other substances such as enzymes, cytokines, and antibodies.

Explanation:
14. a science student claims that a substitution mutation is less likely to affect gene function than an insertion or deletion mutation. use logical reasoning and evaluate this claim.
Because insertions and deletions produce a frame-shift that modifies the interpretation of following codons, they are frequently more detrimental than substitutions that modify only one amino acid.
What is a mutation?A alteration in the DNA sequence of an organism is referred to as a mutation. Errors in the replication of DNA during the process of cell division, exposure to mutagens, or viral infections are all potential causes of mutations.
Base substitutions, deletions, and insertions are the three different kinds of DNA mutations that can occur.
Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, as a result, alters the entire amino acid sequence that follows the mutation, insertions and deletions are typically more harmful than substitutions, in which only one amino acid is changed. This is because frame-shifts change the reading of subsequent codons.

Answer:
use of transgenic crops
Explanation:
Since transgenic crops are genetically modified, the pros are that: there is more crop yield, increased nutrients, etc.
The use of transgenic crops is most likely to be used by agricultural industries. Hence, option A is correct.
What are transgenic crops?Crops that have undergone genetic engineering techniques to alter their DNA are referred to as genetically modified crops. Plant genomes can be modified physically or by transferring sequences contained in T-DNA binary vectors using Agrobacterium.
The goal of introducing a gene combination into a plant is to increase its productivity and usefulness. This technique offers benefits like extended shelf life, increased yield, improved quality, pest resistance, heat, cold, and drought tolerance, as well as resistance to a range of biotic and abiotic challenges.
The use of transgenic crops is most likely to be used by agricultural industries. Hence, option A is correct.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. The complete cell cycle requires 24 hours. Match the average duration to the appropriate cell cycle stage in these cells. M phase prophase metaphase telophase 4.8 hours 14.4 minutes 2.4 hours 36 minutes
Answer:
M phase: 4.8 hr
Prophase: 2.4 hr
Prometaphase: 0.72 hr
Metaphase: 0.24 hr
Anaphase: 0.84 hr
Telophase: 0.6 hr
Explanation:
Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:
M phase: 40/200 = 0.2 x 24 hr = 4.8 hr
Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr
Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr
Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr
Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr
Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.
Answer:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
Explanation:
Pulled = P, Horned = p
Wattled = W, no wattle = w
Polled, wattle goats = P_W_
Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.
PpWw x PpWw
Genotypes ratio of the offspring:
P_W_ - 9/16
P_ww - 3/16
ppW_ - 3/16
ppww - 1/16
Phenotype ratio of the offspring:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
(See the attached image for the Punnet's square)
Some alleles of a gene are dominant to others masking the effect this other alleles.
The polled, or no horn, trait (P) is dominant to the horned (p) trait.
Having wattles (W) is dominant to not having wattles (w).
A breeder crosses a polled, wattled male goat with a polled, wattled female goat.
The phenotypic and genotypic ratios would be
Polled and wattled = P_W_ = 9/16Polled with no wattle = P_ww = 3/16horned and wattled = ppW_ = 3/16horned with no wattle = pwpw = 1/16Parent genotype --- polled, wattled male and female goat -- P_W_
As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.
Hence, they are both heterozygotes with PpWw for the traits.
Parent genotypes: PpWw x PpWw
PW Pw pW pw PW Pw pW pw
PW Pw pW pw
PW PPWW PPWw PpWW PpWw
