Answer:
High to low concentration
Explanation:
The process of substances moving across the cell membrane through channel proteins represents a type of diffusion called facilitated diffusion. This type of diffusion does not require energy intake, and for this reason, substances involved in facilitated diffusion always move from areas of high concentration to areas of low concentration, because going the opposite direction would require ATP (energy).

A farmer breeds two chickens from lines that produce many eggs. Why is this an example of artificial selection
Answer:
He's espically breeding the ones that lay more eggs so the chicks that grow later will produce that much eggs too.
Explanation:
In order to ensure that the chicks that grow later would also lay that many eggs, he specifically breeds the ones that lay more.
What is artificial selection?The employment of technologies like artificial insemination and embryo transfer is known as artificial breeding.
By injecting semen right into the uterus, artificial insemination (AI) is accomplished. In an embryo transfer, fertilized eggs from a donor female are given to a recipient female who will later raise the calf.
Due to the numerous advantages it offers, artificial insemination frequently replaces natural mating in many species of animals.
These advantages include improved genetics, enhanced production efficiency, and increased animal and producer safety.
He intentionally breeds the ones that lay more eggs in order to assure that the chicks that grow later will similarly lay that many eggs.
Thus, this is an example of artificial selection.

What is a zygote? And how are they formed? Please be descriptive In your own words
Answer:
A zygote is a eukaryotic cell. It is a fertilized egg cell. It is formed through the fertilization and fusion process between two gametes. A zygote evolves quickly, and begins sub-dividing itself into smaller cells.
Explanation:
Answer:
a cell
Explanation:
To be more specific a zygote is a fertilized cell, that cell will grow into a new animal or plant. The way the cell is formed is by the feralization of two haploid cells.

With bees in decline how is technology helping fill the gap with farmers? PLZZZ HURRY
Answer:
Humans rely heavily on pollinator bees to sustain food production globally. But for decades, the insects’ population has declined, in part because of pesticide use. If the die-off continues, it will have huge economic and public health consequences for people. William Brangham reports on groups that are working on innovative ways to save the world’s jeopardized bee population — or supplement it.

The function of enzyme are enzymes break down foods into smaller molecules in digestion, Enzymes are not changed or used up in the reaction, but speed up the reaction, enzymes lower the activation energy, allowing the reaction to occur more quickly and enzymes have a specific shape that allow them to bind to only one specific. Thus, option A, C, and D are correct.
What are enzymes?Enzymes are the biological catalyst that speed up the chemical reaction that carries out in the body. Enzymes are protein by nature and there are number of enzymes present in our body such as salivary amylase, pepsin, renin, lyases, lygases etc.
The main function of enzyme is to make the metabolism fast as well as speed up the chemical reaction carried out in the body. The best example of enzyme is salivary amylase which is an enzyme and it is present in the saliva and helps in the digestion of food.
Therefore, The function of enzyme are enzymes break down foods into smaller molecules in digestion, Enzymes are not changed or used up in the reaction, but speed up the reaction, enzymes lower the activation energy, allowing the reaction to occur more quickly and enzymes have a specific shape that allow them to bind to only one specific.

What is true about the cell pictured below and how do
you know?
A. It is in prophase because the nucleus and nucleolus are still visible.
B. It is in metaphase because chromosomes are visible.
C. It is in prophase because the spindle fibers are visible.
D. It is in interphase because the nucleus and nucleolus are still visible.
A........................................
In picture show the interphase stage of the cell cycle because it shows the nucleus and nucleolus DNA is enclosed in chromatin, hence option d is correct.
What is interphase?A cell spends most of its time in what is called interphase, in which it grows, replicates its chromosomes, and gets ready for division.
During interphase cells regulate their gene expression to maintain every character inside the cell before division.
The mechanism for regulating gene expression, RNA synthesis, and DNA replication are all included within the interphase nucleus, which also houses the genomic DNA.
Therefore nucleus and nucleolus are visible in interphase where gene expression is regulated, hence option d is correct.
