Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.

Why did Mendel study pea plants?
They reproduce asexually and have one trait that is easy to observe.
They reproduce asexually and have many traits that are easy to observe.
They reproduce sexually and have one trait that is easy to observe.
They reproduce sexually and have many traits that are easy to observe.
Answer:
For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.
Explanation:
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.
Why did Mendel choose pea plants to study?Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.
What was the purpose of the pea plant study?Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.

How does ATP structure relate to its function?
Answer:
The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.

A nebula is composed of dust and gas, but what are the elements in a nebula?
Answer:
the person above has correct
Explanation:
"Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star."

A certain species of fish (A) preys on a smaller species of fish (B). The smaller species of fish mostly consumes seaweed. What would be the effect of overfishing species A? If species A is overfished, then the drop in population of species A will have a(n) (direct, indirect or cascading) effect on the population of species B. The population of species B will increase. A(n) (direct, indirect, or cascading) effect of overfishing would be a drop in seaweed, because the larger population of species B would consume more seaweed.
Answer:
B. The population of species B will increase, A(n) (direct, indirect, or cascading) effect of overfishing would be a drop in seaweed, because the larger population of species B would consume more seaweed.
Explanation:
As population of Fish A is directly dependent on population of fish B and population of fish B is dependent on seaweed. Overfishing of species A will have a direct effect on species B and population of species B will increase as there will be less predator (species A).
Due to overfishing of species A resulting into increase in species B, there will be an indirect drop in the seaweed, because the larger population of species B would consume more seaweed.
Hence, the correct answer is "B".

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.

According to natural selection, individuals that tend to survive are those that have which of the following?
the ability to quickly produce the most offspring
the largest and strongest body structures
the genetic variations that are best suited for their environment
the longest legs and fastest running speeds
Answer:
The genetic variations that are best suited for their enviornment
Explanation:
Those that are not well suited for their environment will die off, leaving only the ones that are suited for it. This species will slowly take hold until the species has adapted and become a completely different one.
Answer:
The genetic variations that are best suited for their environment
Explanation:
This way they may also have a chance to evolve if natural selection kept going until everyone of the species had that trait.

C.) In this case, the bacteria infected humans through a dog.
D.) In this case, the bacteria had been dormant for decades before regenerating.
Answer:
C). In this case, the bacteria infected humans through a dog.

The Colorado Department of Public Health and Environment (CDPHE) in July 2014 witnessed the 'Yersinia pestis' bacteria from the blood of a patient with Pneumonia. It was later noticed that the patient got infected through a dog suffering Hemoptysis. This pneumonic plague case even caused the human-to-human transmission of the bacteria along with the animal-to-human. Thus, option C correctly displays how the plague is a versatile zoonotic disease.
Answer: C
