<h2>Dinoflagellates thrive in bahia fosforescente</h2>

Explanation:

  • Dinoflagellate, are one-celled aquatic organisms having two dissimilar flagella.
  • It has a characteristics of both plants and animals.
  • Most of the dinoflagellates are marine, but some live in freshwater habitats.
  • Bahia fosforescente is one of the phosphorescent bays where millions of glowing marine dwellers such as dinoflagellates cause the lake to glow a bright blue in night.
  • Dinoflagellates has the characteristics of Bioluminescence which they use it as a defense mechanism.
  • During night, due to the bioluminescence of dinoflagellates,water can have an appearance of sparkling light.
  • Dinoflagellates takes their nutrients from marine organisms, thus they grow or develop well in bahia fosforescente.

A population of 150 individuals has an allele frequency of 0.2 for the dominant allele (H) and a frequency of 0.8 for the recess
Amanda [17]
Hardy-Weinberg Equation (HW) states that following certain biological tenets or requirements, the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimel. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = genotype frequency of homozygous dominant individuals, 2pq = genotype frequency of heterozygous individuals, and q^2 = genotype frequency of homozygous recessive individuals.
The problem states that Ptotal = 150 individuals, H frequency (p) = 0.2, and h frequency (q) = 0.8.
So homozygous dominant individuals (HH) = p^2 = (0.2)^2 = 0.04 or 4% of 150 --> 6 people
Heterozygous individuals (Hh) = 2pq = 2(0.2)(0.8) = 0.32 or 32% of 150
--> 48 people
And homozygous recessive individuals (hh) = q^2 = (0.8)^2 = 0.64 = 64% of 150 --> 96 people
Hope that helps you to understand how to solve these types of population genetics problems!

4. Which of the following statements best describes how the traits of an organism are determined
butalik [34]

Answer Choices:

DNA provides the energy needed for an organism to grow and function

DNA is copied into mRNA, which controls cellular functions

DNA codes for proteins, which allow an organism to grow and function

DNA unzips and each strand codes for a different amino acid

Answer:

DNA codes for proteins, which allow an organism to grow and function

Explanation:

DNA provides the energy needed for an organism to grow and function  - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.

DNA is copied into mRNA, which controls cellular functions  - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.

DNA codes for proteins, which allow an organism to grow and function  - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>

DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid
