Provide a detailed explanation of why meiosis is important in creating genetic variation in a population. Include details on how daughter cells receive genetic information and how they differ from parent cells.

Answers

Answer 1

Answer:

The correct answer is - crossing over, mutations caused during crossing over, and independent assortment.

Explanation:

Meiosis is important as it helps that all organisms form via sexual reproduction contains the correct number of chromosomes in the offspring. Meiosis also produces genetic variation in various ways that are crossing over, mutations caused during crossing over, and independent assortment.

Independent assortment helps in getting half number of chromosomes. In meiosis, crossing over takes place in prophase 1 which results in recombination by an exchange in the arms of chromosomes.

An adaptation is __________.
A. an individual's attempt to conform to its environmentthe cause of natural selectiona trait that gives rise to a new species
B. All of the listed responses are correct.
C. a trait that gives an organism
D. a reproductive advantage in the current environment

Answers

Answer:

The correct answer is - D. a reproductive advantage in the current environment.

Explanation:

Evolutionary adaptations are the adjustments and alteration of the physical structures of the organisms or their traits according to the environment change and it is hereditary. These adjustments or changes help in improving its ability to survive and reproduce and increase its number to pass the genes.

In other words, Evolutionary adaptations are characteristics or traits that are hereditary and enhance an organism's ability to survive and reproduce in a particular environment.

Which of the following describes research that would be considered basic science? A. A professor at a university is observing the mating behavior of freshwater fish, B. A dairy farmer is designing a new machine for milking cows. c. Park rangers are trying to find out why a group of elm trees died. D. Doctors in a hospital are developing a new surgical technique.​

Answers

Answer:

C. But be careful. This question is poorly conceived. Anything could be the answer.

Explanation:

A B and D are all specific to the disciple they are involved in.

That only lets you choose C. You could argue that a physicist or an electrical engineer would not be particularly interested in the death of some elm trees, and I think I would agree with you.

But what other choice to you have?

While the professor is tracking the fresh water fish, how is that benefiting mankind? What is he learning that is universally applicable. I wouldn't choose A.

B is an advance in technology. It might make the dairy farmer's life a whole lot easier, but I don't think it would have very effect on anyone else. Not B.

D: Again this benefits surgeons but again it is technology. I don't think it universally benefits all of humanity except those who are going to be operated on.

So I'll stick with C. People die. So do trees and all vegetation. I'd pick C, but I don't think there is a clear cut answer. Sometimes you get questions that you think the answer resides only in the head of the person writing the question. This is one of them.

How do mountains play a role in precipitation patterns?
a. As water vapor condenses,the air gets warmer b.it changes the amount of rain received c.it changes the direction of the wind d.as vapor condenses,it depends rain or snow on windward slopes

Answers

Answer:

a. As vapor condenses, it depends (specifically; leads to) rain or snow on the windward slope

Explanation:

The orographic effect which is the changes in masses of air as  it moves along the mountain sides, up or down is the way the mountains have an effect on the climate

The orographic effect of mountains can be analyzed based on either the windward side, (which is the side that faces the incoming wind), or the leeward side (which is the opposite side of the mountain)

The moist and warm air from the oceans and other large water bodies are carried by wind onto the mountains where the moist wind is directed upward by the obstructing mountain wall.

As the elevation of the warm moist wind increases along the mountain, the cooler temperatures at the high altitudes forces the air to cool down, until the dew point is reached, which leads to precipitation of rain or snow.

A bacterial isolate is subcultured to two blood agar plates, one of which is incubated in an anaerobic jar, and the other is incubated on a shelf in the incubator. After incubation, growth is observed on the plate from the anaerobic jar, but there is no growth on the plate incubated on the incubator shelf. Based on these results, how would this organism be categorized

Answers

Answer: obligate anaerobe

Explanation: This experiment established that a bacterial isolate is subcultured into same medium in two different plates, but one is placed in an aerobic condition (i.e., presence of oxygen) while the other in an anaerobic condition (i.e., absence of oxygen), and the result shows that there was no growth on the plate incubated on the incubator shelf, whereas there was growth on the plate conditioned anaerobically.

This simply translates that the bacterium does not need oxygen to grow i.e., It’s an anaerobe. Moreso, assuming it grows on the two plates we would say it's a facultative anaerobe.

Thus, since it growth was only established on the plate with anaerobic condition, it's an obligate anaerobic bacterium.

what is the female reproductive system cell

Answers

Answer:

Egg

Explanation:

Reproductive system is the system of an organism encompassed with the function of giving rise to new offsprings. In sexual reproduction, which involves two organisms, one of the organisms is usually a MALE while the other is a FEMALE.

In most sexually reproducing organisms, the female reproductive system undergoes a division called MEIOSIS to produce a sex cell or gamete called EGG CELL. This egg cell gets fertilized by the sperm cell produced by the male to form a zygote. Hence, EGG CELL is the female reproductive system cell.

1) What is the control group? 2) What is the experimental group? 3) What is the independent (manipulated) variable? 4) What is the dependent (responding) variable? 5) What should Tina's conclusion be?

Answers

Complete question:

Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.

1) What is the control group?

2) What is the experimental group?

3) What is the independent (manipulated) variable?

4) What is the dependent (responding) variable?

5) What should Tina's conclusion be?

Answer:

Individuals from test 1Individuals from test 2CaffeineHeart rateTina´s hypothesis is correct. Caffeine increases the heart rate of an earthworm.  

Explanation:

During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.  

The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.

The experimental group is the one affected by the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.  

Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.   Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually represented using the letter Y.  Controlled variable: Refers to the variables that have no influence on the results. These variables do not affect the change in the dependent variable values.  

1) What is the control group?

Individuals from test 1 compose the control group. They are not affected by the treatment. Tina just uses them to measure the normal heart rate and to compare them with individuals from test 2.

2) What is the experimental group?

Individuals from Test 2 compose the experimental group. They are affected by the treatment. Tina drops caffeine on their skin to see how it affects the worms.

3) What is the independent (manipulated) variable?

Caffeine is the independent variable. Tina manipulates the number of drops she places on the worm´s skins.

4) What is the dependent (responding) variable?

Heart rate is the dependent variable. Tina evaluates how the heart rate changes in individuals with or without caffeine.

5) What should Tina's conclusion be?

Caffeine increases the heart rate of an earthworm. It changes from 50 to 68 bpm. Tina´s hypothesis is correct.

The most muscular pump in the heart is the: *
septum
left atrium
left ventricle
right atrium
right ventricle

Answers

Answer:

The heart has four chambers and four main blood vessels that either bring blood to the heart, or carry blood away.

The four chambers are the right atrium and right ventricle and the left atrium and left ventricle. The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs. The aorta is the body's largest artery. It carries oxygen-rich blood from the left ventricle to the rest of the body.

Beneath the tough fibrous coating of the heart, you can see it beating.

Inside the chambers are a series of one-way valves. These keep the blood flowing in one direction.

Dye injected into the superior vena cava, will pass through all the heart's chambers during one cardiac cycle.

Blood first enters the heart's right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle.

When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.

In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.

From there, blood is forced through the mitral valve into the left ventricle. This is the muscular pump that sends blood out to the rest of the body.

When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta.

The aorta and its branches carries the blood to all the body's tissues.

Why is price discrimination not positive under perfect market conditions ​

Answers

Answer:

[u9gbvolgj;t9ug7yh

Explanation:

ft7odt8ugde86rfgef

Price discrimination is impossible in a market with perfect competition, and the average total cost (ATC) curve is identical to the marginal cost curve (MC).

What is price discrimination?

Price discrimination is a sales strategy in which the seller charges different prices for the same item or service oriented on what the seller believes the customer will agree to.

In sheer price discrimination, the seller charges each customer the highest possible price.

Price discrimination occurs when various prices are charged to different customers.

This is not feasible in a perfectly competitive market because there are numerous firms competing for the price; however, it is possible in a monopoly because people have no other place to buy.

In a monopoly, price discrimination is the practice of charging different prices for a product.

Monopolies typically have greater control over providers than regular sellers, allowing them to significantly influence the selling prices of the suppliers.

Thus, due to this, price discrimination is not positive even under perfect market conditions .
