In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals (RR), 257 brown sided individuals (Re) and 557 tan-sided individuals orr). Calculate the following:_______.
a. What is the allele frequency of the Rallele (o)?
b. What is the allele frequency of the rallele (a)?
Migration season comes and 200 of the red-sided individuals leave the nosulation before mating occurs.
c. After migration season what is the new allele frequency of the Rallele (0)?
d. After migration season, what is the new allele frequency of the rallelelo?
e. Which mechanism of evolution (natural selection, genetic drift, or gene flow) caused the allele frequencies to change?

Answers

Answer 1

Answer:

a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1049 / 2420 = 0.433

b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1371 / 2420 = 0.567

c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 649 / 2020 = 0.321

d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 1371 / 2020 = 0.679

e) migration is gene flow  

Explanation:

Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).

A student noticed that when a dog is cut, the dog periodically licks its wounds. Usually
after a few days, the wound begins to heal without ever showing
signs of infection. The
following steps outline the student's line of reasoning:
1. I wonder why the dog's wound doesn't become infected.
2. The dog's saliva must prevent the growth of infection-causing bacteria.
3. I'll obtain a bacterial culture and grow the same kind of bacteria in two identical
culture dishes. Once the bacteria start growing, I'll add dog saliva to only one of the
dishes and leave the other alone. I'll cover both dishes. Then I'll observe what
happens each day for a week.
4. Even after adding the dog saliva to one of the dishes, the bacteria continued to grow
in both dishes over the course of the week. However, the bacteria in the treated dish
grew more slowly than the bacteria in the untreated dish.
5. I think I'll try something else. I'll start with two identical culture dishes, as before, and
use the same kind of bacteria in each dish, but this time I'll treat one dish with dog
saliva before I add the bacteria. I'll observe what happens each day for a week. 12.

Answers

Answer:prophase

Explanation:

Telophase, the fifth and final stage of mitosis, occurs when a parent cell's replicated genetic material is split into two identical daughter cells.

What is mitosis?Mitosis is a stage of the cell cycle during which replicated chromosomes are separated into two new nuclei. Mitosis results in the formation of genetically identical cells with the same number of chromosomes. As a result, mitosis exists as also referred to as equational division. Mitosis is the division of a single cell into two identical daughter cells (cell division). Mitosis is a nuclear division process that occurs in eukaryotic cells when a parent cell divides to produce two identical daughter cells. Mitosis is the separation of the duplicated genetic material carried in the nucleus during cell division.

The two structural classifications are projection neurons and local inter-neurons.
Function classifications are made up of two subcategories: excitatory and inhibitory.
Histological classification includes bipolar, unipolar, and multipolar.
Classifications using a combination of structural, functional, and neurotransmitter type provide the most robust and useful description.
Classification by neurotransmitter type alone provides the most useful description.
A. I only
B. III only
C. I, II, and V only
D. I, II, III, IV, and V
E. I, III, and IV

Answers

Answer:

The correct answer is option D. I, II, III, IV, and V

Explanation:

Neurons are the nerve cells that transmit the information in the form of nerve impulses throughout the body. Neurons are an important part of the body and nervous system as neurons control the movement, any other functions of the body. Classification of neurons is presented on different ways such as structural basis, on the basis of functions, histologically, or on the basis of neurotransmitters used by neurons.

Histological classification - bipolar, unipolar, and multipolar.

Function classifications - excitatory and inhibitory.

structural classification - projection neurons and local interneurons.

All type of classification together makes a robust and very useful description of the neurons.

Answers

Answer:

C (Gene Mutation)

Explanation:

Edge. 2020

Genetic mutation is most likely to cause differences in the population. Therefore, option "C" is correct.

What is a genetic mutation?

A prominent change in the sequence of the DNA is known as a genetic mutation. Mutation can be useful and nonsense. Mutation can alter the function of the DNA gene. To understand the genetic mutations, the sequence of the DNA should be known.

The types of genetic mutations are frameshift mutation, insertion and deletion mutation, translocation mutation, and substitution mutation. Albinism can be genetically transferred to the offspring. Both parents should carry the gene responsible for the albinism in oculocutaneous albinism.

Therefore, Albinism occurs when both parents contribute homozygous genes to offspring.

Photosynthesis is the process through which plants prepare their own food in the presence of sunlight in the chloroplast of the cell.

What is Photosynthesis?

Photosynthesis is the process of transformation of energy from solar energy (radiation) into chemical energy. The chemical energy is present in the form of chemical bonds present in the glucose molecule (carbohydrate).

The process of photosynthesis is commonly written as:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This means that the reactants in the process are six molecules of carbon dioxide and six water molecules, are converted by the light energy (radiation) captured by chlorophyll into a sugar molecule (carbohydrate) and six oxygen molecules, as the products.

A rock sitting on the surface of the Earth is pushed down deep into the Earth over time and is exposed to tremendous heat and pressure over time. Although the rock does not melt, it does change into a new type of rock. How would the new rock be classified? Igneous Igneous Magma Magma Metamorphic Metamorphic Sedimentary

Answers

Answer:Metamorphic

Explanation:

Sedimentary rock is from sand or gravel. Igneous rock is melted rock. Metamorphic rock is rock that has been exposed to high pressure and heat but did not melt

Metamorphism refers to the change in structure and mineral composition of rocks when exposed to extreme temperatures and pressure. The correct option is metamorphic rocks.

What are metamorphic rocks?

Metamorphic rocks are one of the three types of rocks, product of subduction events, melting and transformation.

What is metamorphism?

Metamorphism provokes several changes in an original preexisting rock concerning its structure and mineral composition. The main factors causing these changes are temperature and pressure.

These physic-chemical processes usually occur in deepness and are related to plates movement and subduction processes.

The rising sharped temperature might be caused by magma injection or by a deep placement of the original rock in a subduction zone.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation

According to the metamorphism processes, there are different kinds of metamorphic rocks.

The correct option is metamorphic rocks.

The cell membrane (plasma membrane) is describe as a highly selective
barrier composed of alipid bi-layer. This structure plays an important role
in moving molecules across the cell membrane in order for the cell to
maintain homeostasis. If the cell is unable to take in the materials it needs
or remove vwhat it does not need, the cell may die. This inability of cells to
maintain homeostasis may cause sickness or even death of an organism.
Why is it important that the cell membrane is highly selective?
O So that the cell wall is stabilized and maintains its rigidity.
O To prevent certain ions and molecules from entering or exiting the celI.
O So that proteins and lipids can attach to the membrane where needed.
O To allow movement of materials in and out of the cel.
