In sexual reproduction, how many genes does an offspring receive for each trait? ​

Answers

Answer 1

Answer:

__________

Explanation:

In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent.

Answer 2

Answer:

Each parents gives of half of the genes acquired by the offspring. 46 chromosomes or 23 pairs.

Explanation:

". Each gamete contains half the number of chromosomes, or genetic material, of the organism. So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body. A basic human body cell contains 46 chromosomes, but the egg and sperm only contain half that number, or 23 chromosomes. Why? Well, when an egg and a sperm come together, which is a process called fertilization, they contribute 23 chromosomes each. Add 23 and 23 together, and you get one happy 46-chromosome-containing fertilized egg that can now develop into a new human.

Meiosis

Gametes are produced by a type of cell division known as meiosis. It's meiosis that reduces the number of chromosomes in the cell down to 23. It's also meiosis that makes gametes genetically different from one another. After the cell division takes place, each sperm and each egg has its own unique genetic makeup. In other words, meiosis can be thanked for giving Junior his cute mismatched ears. "

Answer:

The details that could be included in a biography of Frida Kahlo are:

1. a description of the first self-portrait Kahlo painted

3. an account of the accident in which Kahlo was seriously injured  

6. an example of how Kahlo influenced artists who came after her

Explanation:

Frida Kahlo was a Mexican painter.  She was born in Coyoacan, which at that time was a small bus stop on the outskirts of Mexico City. Her father was a painter and photographer of German-Jewish origin.

Kahlo began painting after a serious traffic accident in 1925. Her lifelong pain after the accident was the subject of many of her images. In addition to personal experiences, she also describes how hard life women lived. She was also influenced by the culture of the Mexican indigenous people, and portrayed them in bright colors, with a mixture of realism and symbolism.

In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?

Answers

Answer:

Three different genotypes and two different  colors

Explanation:

Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.

hope this helps!

The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b).

If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb.

BB - black offspringBb - black offspringbb - white offspring

Therefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

DNA gyrase is an VERY important bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase categorized to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. The mechanism by which gyrase is able to influence the topological state of DNA molecules is of inherent interest from an enzymological standpoint.  Much attention has been focused on DNA gyrase as the intracellular target of a number of antibacterial agents as a paradigm for other DNA topoisomerases.  Current knowledge concerning DNA gyrase by addressing a wide range of aspects of the study of this enzyme.  I hope this makes sense to you!

what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’

Answers

Answer:

1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.

2. It contaminated the soil, making it difficult for plants to grow.

Explanation:

As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;

1. The already contaminated water was made worse after it was used to quench the flames from coke.

2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.

The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.

Also, it contaminated the soil also it is difficult for growing the plants.

The problem of reusing contaminated water:

Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2


Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.

Answers

In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.

c. Photosynthesis uses light energy to convert carbon dioxide and oxygen to glucose and water.
d. Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.

Answers

Answer:- D

Photosynthesis used light energy to convert carbon dioxide and water into glucose and oxygen

The statement that best describes photosynthesis is statement d. As it converts carbon dioxide to glucose and oxygen.

Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.During photosynthesis, plants, algae, and some bacteria convert light energy into chemical energy, stored in the bonds of glucose molecules.

The process involves the absorption of light by pigments called chlorophyll, which are present in the chloroplasts of plant cells and other photosynthetic organisms. Chlorophyll uses the light energy to drive the conversion of carbon dioxide and water into glucose and oxygen in a process called the Calvin cycle.

Thus, the correct option is statement D.

What is circulatory system? Name its main organs. A few years ago, a popular clothing store ran TV ads with people doing some amazing dancing. The dancers leaped high in the air and did flips over each other's backs. They were doing the Lindy Hop. The Lindy Hop has a long and interesting history. The Lindy Hop started in 1926 at the Savoy Ballroom in the Harlem neighborhood of New York City. It's a type of swing dance that grew from the earlier swing dances, the Breakaway and the Charleston. It's fast, fun, and full of spectacular moves. The Breakaway was renamed the Lindy Hop in 1927 in honor of Charles Lindbergh's famous flight across the Atlantic Ocean. As Lindy Hoppers tried to outperform each other, they invented new moves. In fact, the dance was banned from the main dance floor at the Savoy because the dancing took up too much space. But soon everyone wanted to dance the Lindy, so the owners of the club moved it to the main dance floor. The dance took off, and the famous back-to-back move was invented in which the woman flips over the man's back. After World War II (19391945), jazz music developed from swing into bebop that people no longer danced to. But in the 1980s, the Lindy Hop had a revival. Now there are Lindy Hop dance clubs in many cities in the United States and Europe. Read this essay and type the topic and thesis statement in the space provided.
