When it comes to population evolution and genetics, we cannot fail to cite the Hardy-Weinberg principle which emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a particular population, the frequencies genotypic proportions will remain constant.

The five requirements for a population to be in Hardy-Weinberg equilibrium are:

Large-scale breeding population: For a population to be in Hardy-Weinberg equilibrium, it is important that this population is large, as small populations favor genetic drift (unanticipated fluctuations in allele frequencies from one generation to another).
Random mating: In order for the Hardy-Weinberg equilibrium to occur, it is necessary that the mating occur at random, with no preference for certain groups within the population. In this case, we say that the population is in panmixia, that is, they all mate at random.
No mutations: Mutations alter the total alleles present in a population (gene pool). Therefore, in a Hardy-Weinberg equilibrium population, no mutations should occur.
No gene flow: When there is gene flow due to migration or immigration of individuals, some genes may be included or excluded from the population. Thus, in an equilibrium situation, no gene flow occurs.
Lack of natural selection: For a population to be in Hardy-Weinberg equilibrium, natural selection must not be acting on it. If natural selection acts, some genotypes will be selected, modifying the allelic frequencies of the population.

You have been asked to lead a research team to observe gorillas in their natural environment, collect DNA samples, and analyze h

defon

Answer:

As i am asked to lead a research team to observe gorillas in their natural environment I will prefer a team having persons expert in having knowledge of forest in which we are doing research on gorillas. They must be experience in working with gorillas and familiar with their nature.

My team should have a person who know to use the tranquilizer gun because to collect the DNA sample gorilla needs to be tranquilized. My team should have one veterinary doctor who can examine the animal and take the DNA sample.

People with Good communication skills, observation skills and critical thinking skills are required in the team to successfully complete the research.

A pure breeding tall pea plant was crossed to dwarf plant. What will be frequency of dwarf plants in F2?

Temka [501]

Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.

A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits.
True breeding organisms are those that share the same genes for the desired traits and are genetically comparable.
These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.
The other allele, referred to as the recessive one, has no effect.

According to the given cross:

TT X tt (parents)

Tt Tt Tt Tt (offspring) all tall

Hence the percentage of dwarf individuals is 0.

In a population, when the birthdate becomes higher than the death rate, the populations growth rate

Marrrta [24]

Answer:

if birth rate become higher than the death rate then the population will increase surely, cuz there are more people who add up to form a population but it's decline rate is lesser.

Cell drinking; cell eating. Both are modeled here and are examples of A) osmosis. B) diffusion. C) endocytosis. Eliminate D) fac

N76 [4]

Answer;

-Endocytosis

Explanation;

-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell

-Phagocytosis: endocytosis of large solid particles (“cell eating”)

-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)

-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell

-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
