How are the graphs of a body chemical controlled by negative feedback and a body chemical controlled by positive feedback similar? How are they different?
Answer:
brainliest plzzzzz
Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.

What is vega? A- Fusing hydrogen at its core B-It has lost its outer shell and only retained hot core that is slowly losing its brightness C- it’s temperature has decreased but it shining brighter than before
Answer: It is fusing hydrogen at its core.
Explanation: Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars.
At its core, it is fusing hydrogen. The explanation is that the centres of main sequence stars fuse hydrogen atoms into helium atoms.
What is Vega?The sun is one of the majority of main sequence stars, which make up about 90% of all stars in the universe.
Astronomers have spent a lot of time studying Vega, which has led to the claim that it is "arguably the next most important star in the sky after the Sun."
Around 12,000 BCE, Vega was the northern pole star; it will be again around the year 13,727 when its declination occurs. The first star other than the Sun whose picture and spectra were captured was Vega.
Therefore, At its core, it is fusing hydrogen. The explanation is that the centres of main sequence stars fuse hydrogen atoms into helium atoms.

The deflection of fluids due to the rotation of earth is the Coriolis effect.
True
False
Answer:
True.
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis. This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
Basically, the effect of the Earth spinning on its axis on winds and currents is that, global winds will move along a curved path and therefore cause ocean currents to curve.
As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises.
Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.
Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.
In conclusion, we can say that the deflection of fluids due to the rotation of earth is the Coriolis effect.

How do volcanic eruptions create rock?
Answer:
Once the Magma has cooled of it will turn into hard solid rock (or if you put cold water on it)
It has also created our different islands that we have today because of volcanoes.
Explanation:
Hope that helps
Answer:
magma is sometimes pushed up toward the surface, notably during volcanic eruptions. As it cools, the magma solidifies in the form of magmatic rocks such as basalt. So the rocks of Earth's crust are constantly being transformed as part of the geological cycle that lasts millions of years.

A food shows many food chains within a community and how they overlap.
Answer:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Answer:
A food web?
Explanation:
Food webs are multiple food chains overlapped. (Usually in the same area)

a researcher proposes a model of an enzyme catalyzed reaction in which reactant is converted to a product. The model is based on the idea that the reactant passes through a transition state within the enzyme substrate complex before the reactant is converted to the product. which of the following statements best helps explain how the enzyme speeds up the reaction ?
Answer:
The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.
Over time, three types of cells derived from this single-celled animal have emerged with specialized functions and they interact as a multicellular organism.
Type 1: Launches the toxin-loaded vesicles. Non-motile
Type 2: Detects the toxin, moves, and hunts the prey.
Type 3: Engulfs the bacteria, breaks them down, and stores the parts. Non-motile
Required:
What organelles do each type have?
Answer:
Golgi bodies, endoplasmic reticulum and lysosomes.
Explanation:
Many vesicles are formed in the Golgi bodies and the endoplasmic reticulum, that is responsible for the transportation of materials from one part of the cell to another. Endoplasmic reticulum is the organelle that launches the toxin-loaded vesicles or in other words it is responsible for detoxification i. e. removal of toxic substances from the cell. Lysosomes is the organelle that act against the microorganisms such as bacteria , virus etc.

Look at metaphase and anaphase. Suggest the purpose of the spindle fibers during mitosis.
Answer:
The spindle fibre is necessary to separate the sister chromatids into opposite sides of the cell.
Please find detailed explanation below
Explanation:
Mitosis is the cell division that produces two daughter cells that are genetically identical to the parent cell. Mitosis occurs in stages viz: prophase, metaphase, anaphase and telophase. The replicated chromosome, aligns at the centre of the cell in the METAPHASE stage and separates into opposite poles in the ANAPHASE stage.
This alignment (at the equator) and separation into opposite pole is possible with the aid of a structure called SPINDLE FIBRES. Spindle is a structure formed from microtubules, which attach to the kinetochores (located in the centromere) of each replicated chromosome to separate them from one another. Hence, the purpose of the spindle fibre during mitotic division is to separate the GENETIC MATERIAL of a parent cell into two daughter cells.

Examination of the amino acid composition of a newly isolated protein indicates the presence of 10 lysines, 5 arginines, and 4 methionines. When the protein is treated with cyanogen bromide, four peptides are obtained. When it is treated with trypsin, 16 peptides are obtained. What do these results suggest regarding the sequence of the protein
Answer:
The protein has a lysine or arginine at it's C-terminal end.
Explanation:
Given isolated protein indicates the presence of 10 lysines, 5 arginines, and 4 methionines. So, sequence of the protein . These results indicate that the sequence of proteins contains lysine or arginine at the end of the C-terminal. Because we have 15 sites that can be separated from trypsin and so it only causes 16 peptides.List the distribution of earths water from the greatest amount to the least amount
