Answer:
A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Explanation:
You just performed 5 cycles and 2 minutes of CPR on an adult. You reassess for a pulse. No pulse is present. What is your next course of action?a. search for an AEDb. call 911 immediatelyc. reinitiate CPRd. none of the above
Answer: The correct answer to the question is option A
SEARCH FOR AN AED.
Explanation: AED stands for Automated External Defibrillator.
It is a machine that is used to re-establish a normal cardiac rythym in cases of cardiac arrest or when the heart stops beating momentarily.
It delivers electric shock via the chest to the heart inorder to stop an an irregular heart rythym and establish an effective one.
From the scenerio in the question,5 cycles and 2minutes of CPR has been done on the victim but no pulse is present, The next best thing to do is to use an AED to shock the victim inorder to re-establish the lost cardiac rythym and pulse respectively.
This is achieved placing the pads on victim, analysis the rythym, move slightly away from the victim to prevent any contact and then shock the victim by pressing the shock button as the AED instructs showing that the rythym presented is a shockable one.

Violet Beauregarde is a character in Charlie and the Chocolate Factory who swelled after eating blueberry gum. What is causing Lisa’s body to swell?
I inferred you are referring to Violet instead.
Answer:
she chews "Gobstoppers" which are not meant for chewing.
Explanation:
Remember, it all started when Violet entered the inventing room and she began to show an interest in gobstoppers, believing them to be similar to gum, even though they were not meant for chewing.
After ignoring the warning from Wonka, she begins chewing the gum which leads her body to swell.
Which phrase describes a lava plateau? O steep-sided mountain O gently sloping mountain hardened magma in a pipe O volcanic material in valleys
Answer:
B. Gently sloping mountain hardened magma in a pipe
Explanation:
A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.
The phrase that describes a lava plateau is "hardened magma in a pipe".
A lava plateau is a large, flat area of land that is formed when lava from a volcanic eruption spreads out over a large area and hardens.
What is magma ?This hardened lava is called "magma", and it typically comes from a "pipe" or vent that connects the Earth's surface to a magma chamber deep beneath the ground. As the lava flows out of the vent, it cools and hardens, creating a flat, solid surface that can stretch for many miles in all directions.
So, the phrase "hardened magma in a pipe" best describes a lava plateau. The other phrases, "steep-sided mountain" and "volcanic material in valleys", describe different types of volcanic landforms.
A steep-sided mountain is a type of volcano that is characterized by a tall, narrow peak and steep slopes. These volcanoes are formed when magma rises up through the Earth's crust and is forced to the surface through a narrow vent.
As the magma erupts, it forms a steep-sided cone-shaped mountain, which can rise to great heights depending on the amount of magma that is ejected.
Volcanic material in valleys is a type of volcanic landform that is characterized by deposits of volcanic ash and other materials that have accumulated in valleys and low-lying areas.
These deposits are usually the result of explosive volcanic eruptions, which can send ash, rocks, and other materials high into the air. As the materials fall back to the ground, they can accumulate in valleys and depressions, forming layers of volcanic material that can be several feet thick.
In summary, while "hardened magma in a pipe" describes a lava plateau, "steep-sided mountain" and "volcanic material in valleys" describe different types of volcanic landforms.

Help me guys please. What is a mutation? What causes mutation?
Answer:
A mutation is a change in a DNA sequence. Mutations are commonly caused by mistakes during DNA replication. However, they can also be caused by ultraviolet radiation, exposure to chemicals called mutagens, and infection by viruses. But, a mutation usually occurs when a nucleotide in the DNA gets changed, causing the nucleotide sequence to be copied incorrectly which leads to the wrong code for a protein. This can sometimes be fatal.

The extensive connective tissue network, which encircles the bases of the pulmonary trunk and aorta and the valves of the heart, is called the ________ of the heart.
[tex] \LARGE{ \bf{ \underline{ \underline{ \color{red}{Answer \: of \: Blank:}}}}}[/tex]
The extensive connective tissue network, which encircles the bases of the pulmonary trunk and aorta and the valves of the heart, is called the Cardiac skeleton of the heart.
Explanation:-The cardiac skeleton consists of four bands of dense connective tissue, called fibrous rings, that surround the base of the pulmonary trunk, aorta, and mitral and tricuspid valves.MayInteresting facts about Human[♥️]!!The average heart is the size of an adult fist.Your heart will beat about 115,000 times each day.The beating sound your heart makes is caused by the opening and closing of its valves.The human heart weighs less than one pound, but a man’s heart is typically two ounces heavier than a woman’s.A woman’s heart beats slightly faster than a man’s.There is such a thing as a broken heart. Symptoms are similar to a heart attack but the cause is usually stress and not heart disease.Laughing is good for your heart.

A bacterial culture is being tested for its ability to reduce nitrate. After incubation and growth of the bacteria in nitrate broth, there is no accumulation of gas in the Durham tube. The test for the presence of nitrite is colorless. When zinc powder is added, a bright red color develops. Interpret these results.
Answer:
All this combination of reactions is summarized in that the bacteria reduced nitrate, that is, they added protons to said compound, giving nitrite as a product.
By promoting the appearance of nitrite and that it increases in its concentrations when the zinc dust is thrown away, it becomes reddish since there was a change in pH, that is, the medium was acidified.
Explanation:
Some bacteria take nitrate as a source and end up generating an oxide reduction reaction that gives nitrite as a product, if this reaction advances in a chain, that is, the nitrite is reduced after the nitrate, the product in the future would be ammonia

what is maeant by sexual reproduction
Answer:
Sexual reproduction is a mode of reproduction involving the fusion of haploid female gamete (egg cell) and haploid male gamete (sperm cell). The fusion of these gametes occurs at fertilization resulting in the formation of a diploid zygote. ... Two major types of sexual reproduction are syngamy and conjugation.
Explanation:
Answer:
The production of a new living beings by intercourse of two different genes is called sexual reproduction.
Explanation:
In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another to produce an organism composed of cells with two sets of chromosomes.
