Answer:
Prenatal development
Explanation:
Prenatal development is the phase of growth and development in which a single-celled zygote grows into an embryo followed by the fetus and then a baby in the womb of a lady.
The process of prenatal development is very complicated which is divided into three phases:
1. Germinal phase: during the first two weeks after the conception in which the single-celled zygote develops.
2. Embryonic period: during which the zygote grows into the embryo and lasts from the second week to the eighth week.
3. Fetal period: During which the embryo grows to form a fetus which matures into a baby and is born.
Thus, Prenatal development is the correct answer.
Answer:
Prenatal.
Explanation:
The sexual reproduction may be defined the process of fusion of the male sperm and female ovum that leads to the formation of the zygote. Zygote is diploid in nature.
The prenatal development includes all the stages that are involved in the development of the single cell till the completion of the nine months of the fetus. The development of all organs and the process of the cell specification all occurs in the prenatal development stage.
Thus, the answer is prenatal.

Answer:
Explanation:
To determine the type of microscope used to capture the image of a cell's mitochondrion, you would typically need additional information, such as the features of the microscope and the microscopy technique employed. Microscopes commonly used to visualize cell structures include optical microscopes, electron microscopes, and fluorescence microscopes, each with its own capabilities and applications. If you have more details about the image or the microscope used, I'd be happy to provide further assistance.
example, what would happen if a person sweats
when temperature decreases?
Answer:
Most general problem: Homeostasis would be thrown off.
Explanation:
When a person sweats, they are trying to cool themselves off from a high internal body temperature, sweating when cold can make the person colder and make it even harder for that person to maintain homeostasis without throwing multiple body functions out of sync.
However there is a condition that is associated with Hyperhyrosis (increased sweating) that makes a person sweat when cold: cold sweats, however this is also concerning when a person is cold. But as long as a person has no other symptoms, it is no need for concern.
Other than that, organs can take damage. It would be like the skin going into goose bumps when a person is getting heat stroke, the organs are too hot as is the skin, but it is unable to let any response out to maintain homeostasis.
Cold sweats are also triggered by a fight or flight responce. So the main take away is that the body would not know how to react because Homeostasis has been thrown off.
Positive feedback amplifies changes, so if your body used this to regulate temperature, you would sweat when cold, further lowering your body temperature. This could lead to dangerous situations, such as hypothermia. Normally, the body uses negative feedback to regulate temperature.
If the body used positive feedback to regulate body temperature, it would disrupt the body's homeostasis. Positive feedback amplifies changes rather than counteracting them like negative feedback. So, if you began to sweat when your body temperature decreased, you would lose even more body heat, causing your body temperature to drop further. This could lead to a dangerous situation, such as hypothermia, where your body's temperature falls too low to perform physiological functions correctly.
Normally, body temperature is regulated by negative feedback. When the body gets too warm, it sweats to cool down, and when the body gets too cold, it shivers to produce heat. Thus, flipping this balance would disrupt the body's ability to maintain a stable internal environment.

Answer:
D) omnivores
Explanation:
Clearing a forest to plant corn would have several impacts on the environment. Firstly, it would result in the loss of habitat for a variety of animal and plant species that live in the forest, leading to a reduction in biodiversity.
Corn, also known as maize, is a cereal crop that is widely grown throughout the world. It is a member of the grass family and is primarily used as a food crop for both humans and animals
Secondly, it would lead to soil erosion, as the trees and other vegetation that previously held the soil in place would be removed, and the exposed soil would be more susceptible to erosion by wind and rain.
This would result in a loss of soil fertility, which would require increased use of fertilizers to maintain crop yields.
Additionally, the deforestation would increase carbon emissions, contributing to climate change. The removal of trees would also reduce the ability of the forest to absorb and store carbon dioxide from the atmosphere through photosynthesis.
Finally, clearing the forest would also impact the water cycle, potentially leading to changes in rainfall patterns and the drying up of nearby rivers and streams.
