This diagram summarizes sexual reproduction. Explain why meiosis rather than mitosis must be used to form the gametes needed for sexual reproduction.

Answers

Answer:

Please fine the explanation below.

Explanation:

Meiosis and mitosis are the two types of cellular division that occurs in living organisms. However, meiosis is used strictly for sexual reproduction (to produce gametes) while mitosis is used for growth and repair. Meiosis is the process by which four daughter cells with a reduced number of chromosomes are produced.

Unlike meiosis, Mitosis produces two daughter cells with the same number of chromosome as parent cell. Meiosis must be used to form the gametes needed for sexual reproduction because it REDUCES THE CHROMOSOME NUMBER IN THE GAMETES BY HALF. THIS ALLOWS THAT WHEN TWO OF THE GAMETES (MALE AND FEMALE) COMBINE DURING FERTILIZATION, AN ORGANISM WITH CORRECT NUMBER OF CHROMOSOME WILL BE PRODUCED.

what would happen if glycolysis stopped happening in a cell?

A. lactic acid would build up in the cell
B. the curbs cycle could but function
C. ATP molecules would be produced
D. anaerobic respiration would begin

Answers

Answer:

Glycolysis must occur before ATP is produced, regardless of whether it is fermentation or the citric acid cycle that follows. Because hexokinase is involved in this preliminary step, if its activity were stopped, the cell could not continue to produce ATP by either pathway.

In humans and other multicellular organisms, which substance plays a central role as an
energy source?
water
fats
O carbohydrates
proteins

Answers

Explanation:

Carbohydrates are the main energy source of the human diet. 

Fats are also a source of energy but fats are the slowest source of energy.

In humans and other multicellular organisms Carbohydrates plays central role as an energy source.

Carbohydrates are the nutrients most frequently used as an energy source, as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body.

What are the Carbohydrates?

A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1.

Carbohydrate is a synonym of saccharide, a group that includes sugars, starch, and cellulose.

The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Importance of Carbohydrates:

- Serves as energy store and structural and structural components.

- Backbone of genetic material RNA

- Central to nutrition and found in variety of natural and processed foods.

Cereals, potatoes, fruits, and sugars are rich in carbohydrates.

Fats as an Energy Source:

Fat is an important component of a diet designed to fuel exercise. Fat provides the main fuel source for long-duration, low- to moderate-intensity exercise.

Fat to fuel exercise has three key parts:

Digestion: Fat is slow to digest and be converted into a usable form of energy. This process can take up to six hours.

Transportation: After the body breaks down fat, it needs time to transport it to the working muscles before it can be used as energy.

Conversion: Converting stored body fat into energy takes a great deal of oxygen, which requires decreased exercise intensity.

Protein as an energy source:

Protein is what is known as a macronutrient and  is responsible for a large portion of the body's energy supplies.

Only a small amount of protein is directly converted into energy, because it isn't stored away in the body like carbohydrates and fats.

Protein isn't the ideal source for energy but present it in the diet is crucial to maintain high energy levels.

Protein also helps in maintaining muscle mass, which in turn supports a healthy metabolism rate.

Which form of active transport is being shown below?

Answers

Answer:

Sodium-Potassium pump, Exocytosis, and Endocytosis are forms of active transport.

Explanation:

We can say the transport is active transport if there is energy used in the transportation of molecules from one place to another. Active transport is a type of transport in which energy is used in the form of ATP for the movement of molecules from one place to another. Forms of active transport are Sodium-Potassium pump, Exocytosis, and Endocytosis. in Exocytosis, cells transport molecules out of the cell by using energy while in Endocytosis, cells absorb molecules from outside by using energy. In Sodium-Potassium pump, the Sodium and Potassium ions are transported by using energy.

Describe budding in yeast plants.

Answers

Answer:

yeast cells produce asexually by asymmetric division process called budding,in yeast budding usually occurs during the abundant supply of nutrition

Most yeasts reproduce asexually by the asymmetric division process which is called budding. It First produces a small protuberance on the parent cell that grows to a full size and forms a bud. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell. In yeast, budding usually occurs during the abundant supply of nutrition. In this process of reproduction, a small bud arises as an outgrowth of the parent body. ... The newly created bud divides and grows into a new cell.

How do pH and temperature effect enzyme activity?

Answers

Explanation:

Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.

What is generalist species

Answers

A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources. A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however.

example:

Raccoons are an example of a generalist species. They can live in a wide variety of environments, including forests, mountains, and large cities, which they do throughout North America. Raccoons are omnivores and can feast on everything from fruit and nuts to insects, frogs, eggs, and human trash.

Red fruits (T-) is dominant to tangerine fruits (tt), and smooth leaf (H-) is dominant to hair leaf (hh). Suppose the recombination frequency between these genes is 16%. You take a pure-breeding plant with red fruits and smooth leaves and cross it with a pure-breeding plant with tangerine fruits and hairy leaves. You perform a test-cross with the F1 generation and produce 500 offspring. What is the approximate number of offspring for each possible phenotype?

A. 40 red, smooth; 40 tangerine, hairy; 210 red, hairy; 210 tangerine, smooth

B. 40 red, smooth; 40 tangerine, hairy; 40 red, hairy; 40 tangerine, smooth

C. 42 red, smooth; 42 tangerine, hairy; 8 red, hairy; 8 tangerine, smooth

D. 84 red, smooth; 84 tangerine, hairy; 16 red, hairy; 16 tangerine, smooth

E. 210 red, smooth; 210 tangerine, hairy; 40 red, hairy; 40 tangerine, smooth

When you perform a three-point test cross to determine the linkage between three genes, you found that distance between the three genes were 16 and 8 map units. Of 1000 progeny produced in the test cross, you observe 7 double recombinants. What is the interference?

A.
0.547

B.
0.453

C.
0.16

D.
0.08

E.
0.0128

Answers

Answer:

1. E. 210 red, smooth; 210 tangerine, hairy; 40 red, hairy; 40 tangerine, smooth

2. B. 0.453

Explanation:

1. Recombination frequency = 16 %  

100 % _____ 500 offspring

16 % ______ X = 80 of the offspring will be recombinant (i.e., 40 red, hairy + 40 tangerine, smooth), while the remainder progeny (420) will have the parental genotypes >> 210 red, smooth and 210 tangerine, hairy (i.e., 210 + 210 = 420).

2. Expected double recombinants = 0.16 x 0.08 x 1000 = 12.8  

Coefficient of coincidence (c) = 7/12.8 = 0,546875

Coefficient of interference (CI) = 1 - c >>

CI = 1 - 0,546875 = 0.453125
