If there is a mutation in a zygote, where is it likely to be found in the fetus?A: The mutation will show up in any fetal cells formed by mitosis but not in those formed by meiosis.

B: The mutation will only be in the one cell that was the original zygote and the other cells of the fetus will not have it.

C: The mutation will occur in all the cells of the fetus since they all formed by mitosis from the zygote.

D: The mutation will only be found in the types of cells in the fetus that are formed by meiosis.

Answers

Answer 1
Answer: The correct answer is C.
The zygote is a single fertilized egg cell that the embryo develops from.
This one cell possesses one copy of DNA that is going to be passed to all other cells in the embryo because all other cells of the embryo develop through mitotic divisions of the zygote.
Therefore, if a mutation happens in the zygote DNA, all of the cells in the embryo are going to have it as well.

What are the possible negatives of being a marine biologist?

Answers

Answer: There are negatives and I will describe them

Explanation:

There can be problems such as climate change in which can affect on what days we are allowed to go into the water. You always have to travel so you won’t be home much which can impact on your loved ones. This can get very frustrating when you’re finding yourself lost and when you are supposed to be finding something but you have already discovered it.

Final answer:

When taking about negatives of being a marine biologist, they faces challenges including shifts in marine populations due to increased ocean temperatures, dealing with the aftermaths of oil spills which harm marine ecosystems, and the regulation and monitoring of growing fish populations.

Explanation:

The role of a marine biologist entails a variety of challenges and potential negatives.

First, due to increases in greenhouse gas emissions resulting in increased ocean temperatures, marine biologists may face difficulties in studying and protecting marine species that are drastically affected by these shifts in their environment. They have to observe, study and document these changes which can be physically and mentally exhausting.

Furthermore, marine biologists often have to deal with the aftermaths of environmental degradation such as oil spills. Oil spills reduce the amount of light and oxygen entering the ocean, causing harm to marine life such as phytoplankton and animals.

This creates a stressful and dismal work environment, as the marine biologists try to limit the damage and save as many organisms as possible.

Finally, the decrease in human activities like fishing that lead to rebounds in fish populations actually translates to additional work for a marine biologist.

They have to monitor these fast-growing populations, ensure they do not become invasive and disrupt the marine ecosystem, and study their effects on other marine organisms. This cycle of work is perpetual and can be overwhelming for some.

What makes up all of the living and nonliving things that surround and support you? the atmosphere. the soil. the troposphere. the environment.

Answers

Answer: The environment.

Explanation: The environment consists of both the factors like biotic and abiotic factors. The interaction between these factors defines an environment.

The abiotic factors found in the environment consists of the soil, mountain, water, clouds and other non living parts. The biotic factors of the environment consists of the plants and animals.

Environment consists of both biotic and abiotic factors.
Environment- the conditions that surrounds someone or something. It affects growth, health, progress ,etc.

In which North Carolina ecological region would you most likely grow sweet potatoes ? A.)Piedmont. B.)tidewater. C.)coastal plain. D.)mountains

Answers

Coastal Plain. The soil is sandier and better for sweet potatoes to grow. I asked my dad, who is a biologist and has worked for North Carolina, in all of its regions, for more than twenty years. Hope this helps.
The right answer for the question that is being asked and shown above is that: "D.)mountains." In the mountain areas of North Carolina's ecological region would you most likely grow sweet potatoes. It grows there very well.
