An endangered species of wildflower has been reduced to a single small population in a mountain meadow. An early spring blizzard

buries and kills all but three of the remaining plants, one of which has a rare allele. The resulting evolutionary change in the population is an example of:

Answer:

Parallel Evolution

Explanation:

It is because only three members are normal while one of them has a rare recessive allele. Due to parallel evolution, the recessive allele will now  become common as the other previously distinguished dominant alleles and now all the traits will be in a uniform equilibrium according to Hardy-Weinberg Theorem.

Answer:

Bottleneck/ genetic drift

Explanation:

Bottleneck can be described as a situation whereby a  population of an organism is negatively affected through some certain events such as uncontrollable hunting of the specie,  destruction of habitat or environmental circumstances or disaster, and results to a reduction of the population.

Bottleneck is known to be a type of genetic drift, and its effect drastically reduces the population size of an organism. It also brings about a random change in the frequency of the alleles, which can be described as an evolutionary change.

In this case, what caused a reduction and evolutionary change of species of wildflower to mountain meadow is bottleneck.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
klasskru [66]

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells etc. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its complementary
Zanzabum

Answer: See attached picture.

Explanation:

DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.

The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.

<u>What distinguishes one polynucleotide from another is the nitrogenous base</u>, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.

The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.

A recessive allele does not affect the phenotype of a heterozygous person.
Effectus [21]

Answer: A. true

Explanation: The phenotype is the physical characteristics of a person. So, if a person has brown eyes, which may be a characteristic that is dominant, then they would have a genotype of BB or Bb. The reason why Bb, heterozygous, is not a different color is because the recessive b does not affect the dominant B allele.

Hope this helps!!!
