O galactic cannibalism
O gravitational lensing
O globular cluster
O irregular galaxy meeting

Answers

Answer 1

Galactic cannibalism is referred when one galaxy collides with another.

what is galactic cannibalism?

Galactic cannibalism is the process by which a big galaxy combines with a companion through tidal gravitational interactions, creating a larger, frequently irregular galaxy.

In a new study, researchers channelled their inner Indiana Jones to demonstrate that the Milky Way, our home galaxy, once gobbled up five smaller galaxies.

That will help scientists comprehend how the Milky Way and Andromeda will engage with other, tiny, nearby galaxies and how, eventually, they will merge and join after billions of years in our portion of the cosmos.

Therefore, Option A is correct.

why do veins have valves

Answers

Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.

An experiment was conducted to demonstrate the passage of glucose and starch across a selectively permeable membrane that allows monomers but not polymers to diffuse through.

Glucose and starch powders were mixed in 10 ml of water and poured into a cellulose bag, which was then sealed at both ends and placed in a beaker of water. After 30 minutes, the presence of glucose in the beaker was recorded with a testing paper, which turns green if glucose is present. The presence of starch was recorded by adding a few drops of iodine, which causes the solution to turn violet if starch is present.

A beaker filled with 100 milliliters of distilled water. A bag filled with 10 milliliters of water and a solution of 2 percent glucose and 2 percent starch is placed in the beaker of water.

Which statement best describes the expected result?

A) The testing paper will turn green and the solution will turn violet.
B) The testing paper will turn green and the solution will not turn violet.
C) The testing paper will not turn green and the solution will turn violet.
D) The testing paper will not turn green and the solution will not turn violet.

Answers

Answer:

B

Explanation:

because if you read the first paragraph, the membrane will only allow monomers not polymers. glucose is a monomer and starch is a polymer. so the membrane will only take glucose and the color for glucose therefore the color is only green.

How is transcription similar to replication and how is it different?

Answers

Answer:

Transcription and replication are important processes that occur in cells but have distinct differences.

Similarities between transcription and replication:

1. Both transcription and replication involve the synthesis of nucleic acids. In replication, DNA is copied to produce an identical DNA molecule, while in transcription, DNA is used as a template to produce RNA.

2. Both processes occur in the nucleus of eukaryotic cells, although replication also occurs in the cytoplasm of prokaryotic cells.

Differences between transcription and replication:

1. Template: In replication, the entire DNA molecule serves as the template for copying. However, in transcription, only a specific DNA segment, called a gene, serves as the template for synthesizing an RNA molecule.

2. Product: Replication results in the production of an identical DNA molecule, while transcription produces an RNA molecule that is complementary to the DNA template.

3. Enzymes involved: Replication requires the involvement of multiple enzymes, including DNA polymerase, helicase, and ligase. Transcription, on the other hand, involves RNA polymerase, which catalyzes the synthesis of RNA from the DNA template.

4. Base pairing: During replication, DNA bases pair with their complementary bases (A with T and C with G) to produce an exact copy. In transcription, RNA bases pair with complementary DNA bases (A with U and C with G), resulting in an RNA molecule complementary to the template DNA strand.

Overall, while transcription and replication involve the synthesis of nucleic acids, they differ in terms of their templates, products, enzymes involved, and base pairing patterns. These processes are essential for cell function and crucial in genetic information transfer and maintenance.

He is either not carrying the gene for RP or the RP gene has mutated.

Explanation:

RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.

The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.

In developing countries with high population rates, at which trophic level do people generally thrive?

Answers

In developing countries with high population rates, people generally thrive at a trophic level of 2.2.

Trophic levels are the positions that feed in a food chain or web. The population size diminishes as you move up the trophic levels of an environment.

Numerous consumers consume food at various trophic levels. When people eat plants like vegetables, they are the primary consumers. When they eat cows, they are incidental consumers. When they eat fillets, they are secondary consumers.

Higher trophic levels typically have fewer creatures since there is less energy there. At higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic-level creatures is known as biomass.

Joe has blonde hair. Joe's father has brown hair. Joe's mother also has brown hair. Joe's father and Joe's mother want to have another child. What is the probability that the child will have brown hair? Support your reasoning with a Punnett Square.

Answers

Answer:

Assuming a single gene determines that hair color with two alleles (brown and blonde), and that both parents are heterozygous (Bb) for this gene, the Punnett square would look like this:

see attachment:

So, there is a 75% chance that the child will have brown hair (either BB or Bb), and a 25% chance that the child will have blonde hair (bb).

This calculation is based on the principles of Mendelian genetics, which state that each parent contributes one allele to their child for each gene and that the dominant allele (B) masks the recessive allele (b) in a heterozygous individual (Bb).

Therefore, based on the given information, the probability that Joe's father and mother will have a child with brown hair is 75%, and the probability that the child will have blonde hair is 25%.

The density of gas particles in a section of Earth's atmosphere decreases. Which of the following is the most likely explanation for this event?
The air pressure in that section of Earth's atmosphere decreased.
The air pressure in that section of Earth's atmosphere increased.
The total number of gas particles in Earth's atmosphere decreased.
O The total number of gas particles in Earth's atmosphere increased.

Answers

The most likely explanation for the decrease in the density of gas particles in a section of Earth's atmosphere is that the air pressure in that section of the atmosphere decreased.

Density is defined as mass per unit volume. In the case of a gas, density is directly related to the number of gas particles (molecules or atoms) present in a given volume. When the air pressure decreases, it means that there are fewer gas particles exerting force per unit area. As a result, the density of gas particles in that section of the atmosphere decreases.

Air pressure is the force exerted by the gas particles on the walls of the container or the surroundings. It is influenced by several factors, including temperature, altitude, and the presence of other gases. Changes in these factors can cause fluctuations in air pressure. For example, if there is a decrease in temperature, the gas particles lose kinetic energy, which leads to decreased pressure and density.

It is important to note that the total number of gas particles in Earth's atmosphere does not necessarily change significantly over short periods of time. The atmosphere is composed of a vast number of gas molecules, and while there may be variations due to natural processes, such as volcanic eruptions or biological activities, these changes are relatively small compared to the overall composition of the atmosphere.

Therefore, the most likely explanation for the decrease in density of gas particles in a section of Earth's atmosphere is a decrease in air pressure, which can occur due to various factors such as weather systems, changes in altitude, or movement of air masses.
