Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?

Answers

Answer 1

Answer:

Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.

Explanation:

Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.

In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

Use the scenario to answer the following question. A forest ecosystem is home to mountain lions, coyotes, bobcats and deer. The deer eat grass. The mountain tions, coyotes, and babcats eat deer. Hunters began killing large numbers of mountain lions, coyotes, and bobcats. About twenty years later, the deer population had largely increased. The teacher asked the students to explain why the population of deer had a large increase in population size. Which student's argument MOST accurately explains the increase in the deer population? A Student 4: The deer population increased because with fewer mountain lions, coyotes, and babcats there was less competition within the deer population. B. Student 1The number of deer increased because deer populations are always increasing, even when there are mountain lions, coyotes, and bobcats preying on them. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat. D Student 2: The number of deer increased because without mountain , coyotes, and bobcats, the deer longer and had more offspring that also lived longer,

Answers

Answer:

A. student 4

Explanation:

The population of deer increase because with fewer mountain lions, coyotes and bobcats there was less competition within the deer population

The correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."

What is food chain?

The food chain describes the feeding relationships that exists in nature. Now this ecosystem has the food chain; grass ---> Deer ----> babcats ---> coyotes  ----> mountain lions.

Now we are also told that the mountain lions eat the the bobcats and the hunters are killing the mountain lions, coyotes, and bobcats, the predators of the deer hence been removed hence the deer population multiplies.

Therefore, the correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."

The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. The tufts have hooks at the tips and barbs along their length that lock and interlink with the ant’s setae, small hairs that cover the body of the ant. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it. As the ant attempts to remove the tufts, it entangles itself more, becoming immobilized.Which two systems most directly interact in the fuzzy millipede’s defense against ants?

Answers

Answer:

Genetic diversity has decreased due to inbreeding due to dwindling population size.

Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.

What are the causes of inbreeding in Cheetahs?

Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.

Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.

Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.

Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

¿Qué sucede si una célula se encuentra en la fase G0 del ciclo celular? ¿qué células nunca salen de esta fase?

Answers

Answer:

las células en fase G0 no se dividen. Un ejemplo de células en fase G0 son las neuronas y las células del músculo de corazón

Explanation:

El ciclo celular es una serie de eventos asociados al crecimiento y división de una célula. El ciclo celular consta de una fase de crecimiento o 'interfase' (la cual a su vez se divide en 3 fases: la fase G1, S y G2) y la fase de división celular (la cual a su vez se divide en mitosis y citocinesis). Sin embargo, hay células que no entran en fase G1 y en lugar de ello se dirigen a un estadio celular conocido como fase G0. La fase G0 es una es un estadio en el cual se encuentran células maduras que no se dividen hasta recibir un estímulo/señal que dispare la entrada de la célula en fase G1, donde la célula sintetiza los ARN mensajeros y proteínas necesarios para las etapas celulares posteriores que conducen a la división celular. Las células en fase G0 no crecen, pero poseen un metabolismo activo. Ejemplos de células en fase G0 incluyen las neuronas, células musculares poli-nucleadas, hepatocitos, etc. (es decir, células maduras y post-mitóticas que son incapaces de reproducirse).

Pollutants concentrated in the northern part of the Gulf of Mexico often create a dead zone. A dead zone is an area of an aquatic ecosystem that does not have enough oxygen to support sea life. Some of the chemicals that cause the Gulf dead zone come from as far away as Montana. Use this information and what you know of United States geography to select the statement that BEST explains how pollutants from Montana have an impact in the Gulf of Mexico.

Answers

Answer and Explanation:

Hello. You did not present the answer options, but we can say that Montana pollutants have an impact on the Gulf of Mexico, due to the Mississippi River. That's because Montana and the Mississippi River are in the same hydrographic basin, which causes Montana pollutants to reach the Mississippi River, which takes these pollutants to the Gulf of Mexico, as the Mississippi River flows into the Gulf of Mexico.

Therefore, we can say that Montana pollutants are easily taken to the Gulf of Mexico and this impacts marine life in an influential way.

The correct answer is - C. the arrows from the Earth's surface to the atmosphere and from the atmosphere to the Earth's surface.

Explanation:

Interaction between radiation and greenhouse gases can be demonstrated or represented by a model which shows how the radiation from different sources of the earth's surface is released in the atmosphere and how the radiation comes to the earth's surface from the atmosphere of the earth.

The radiation trapped by the greenhouse gases and more infrared radiation will be absorbed and emitted back toward Earth's surface, which affects and show more greenhouse effect.

Which of the following is a result of continental drift?

It causes climate change, which puts selective pressure on organisms.
It results in intentional introduction of invasive species, leading to competition.
It causes the buildup of atmospheric carbon, leading to climate change.
It results in habitat fragmentation, due to construction of new buildings.

Answers

I think the answer would be B but none of them are great. Continental drift is the gradual movement of our land masses. Knowing this we can eliminate option D because it identifies buildings as a cause. A and C both discuss climate change which is not a product of continents moving. The elimination leaves option B however because these changes would occur gradually, it is unlikely that species would become invasive.
