Answer:
Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.

Why is sunlight necessary for photosynthesis?
Answer:
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

How does the body regulate dopamine
Answer:
Self discipline
Explanation:
Answer:
Inside the brain, dopamine plays important roles in executive functions, motor control, motivation, arousal, reinforcement, and reward, as well as lower-level functions including lactation, sexual gratification, and nausea. The dopaminergic cell groups and pathways make up the dopamine system which is neuromodulatory.
Explanation:
Striatal dopamine release is mediated by vesicular exocytosis. Active zone-like sites are required for rapid and efficient dopamine secretion. Localized dopamine release generates signaling hotspots and is powerfully regulated. Some striatal dopamine release is independent of ascending action potentials.

The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work
Answer:
2754.33% increase
Explanation:
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%
Percent change = 2754.33% increase
Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.
The total increase is 2754.33% increase
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [tex]\frac{[(72500 MW - 2540 MW)}{ 2540 MW }* 100%[/tex]
After solving the equation the percent change = 2754.33% increase.

A species of bird ate many types of seeds, each type coming from a different species
of tree. The birds' beaks varied in size, with some individuals having slightly smaller
beaks and others having slightly larger beaks.
slightly smaller beak
slightly larger beak
A few years went by without much rain, and the only species of tree that survived had
large seeds. Many generations later, almost all the birds had the slightly larger beaks.
How is this best explained?
Answer:
I took this in middle school option 3
Explanation:
Answer:
The bird most likely had to adapt so they had to eat whatever they could. Doing so made their beaks larger, the muscle under neath probably started to grow from all the movement trying to eat the large seeds. LOL i really dont know but it seem reasonable i guess.

What is the function of the structure identified by the red arrow? (2 points)
food capture
mobility
DNA transfer
Protection
Note about the question:
You will find the image in the attached files
Answer:
Protection
Explanation:
The red arrow seems to be pointing to the membrane of bacteria cells. Probably the green structure also includes the cell wall.
Bacteria are a wide group of unicellular prokaryotic microorganisms with a simple structure and sized between 1 to 10 micrometers. These organisms lack a nucleus, nuclear membrane, and organelles. They only present plasmids and ribosomes. They have a cell membrane and a cell wall that protects the cell. Some of them can also show a capsule.
Membranes and cell walls delimitate and protect the cells from different extracellular factors that might damage them. The membrane constitutes a selectively permeable barrier that allows the free pass of only a few substances while it blocks others.

Explanation:
The green algae relate to land plants in the following ways:
They both have chloroplasts.Both have a cell nucleus.Both have a cell wall.Thus, the correct options are A, B, and E.
What are Green algae?Green algae may be defined as a type of eukaryotic organism that has photosynthetic pigments a and b. Such a type of algae also stores carbohydrates as starch.
Green algae mostly live in freshwater environments, ranging from unicellular flagellates to more complex multicellular forms.
Both land plants and green algae have a photosynthetic organelle known as chloroplast. The cell wall of land plants as well as green algae are made up of cellulose, hemicellulose, and pectins.
Both eukaryotic classifications possess a well-defined cell nucleus, nuclear membrane, and other membrane-bound cell organelles.
Therefore, the correct options for this question are A, B, and E.
