Hey there! :D

When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".

I hope this helps!

Select the best answer that describes how lionfish are impacting biodiversity in Florida. O Lionfish are consuming large quantit
jolli1 [7]

Answer:

Lionfish are rapidly consuming many smaller fish species along the coast at depths up to 90 meters.

Explanation:

Lionfish is an invasive species that has been successfully established in the Atlantic Ocean. It is a tropical species that lives mostly in reefs and rocks that provide protection. It <u>i</u><u>nhabits waters from the coast to 50 meters deep. </u>

Because of its high densities in the Atlantic, Lionfish is a promoter of ecological, economic, socio-cultural consequences. They only have a few predators and consume a high diversity of prey items. They produce an ecological imbalance in the trophic chains of the marine ecosystem. When competing with native piscivores, they imbalance the dynamics of fish communities in coral reefs and mangroves. The <u>density of young and herbivores fishes has decreased because of their predation by the lionfish</u><u>.</u> By <u>predating on algae eating fishes</u>, they provoke a sharp increase in algae populations, which produces serious damages in the coral reefs, enhancing their mortality. The main consequences of these damages are marine biodiversity loss, water quality decrease, ecosystem recovery difficulty, and impacts on food provisioning for many other ocean species.

The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.

Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.
Irina-Kira [14]

<u> Allele frequencies to change from one generation to the next.-</u>

<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>

  • Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
  • When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.

Why do allele frequencies change from one generation to the next?

Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.

No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.

What are 5 factors that cause changes in allele frequency?

  • A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
  • These include natural selection, gene flow, genetic drift, and mutation.
