Answer: That is true. All muscle movements, including both voluntary and involuntary, in the human body go through control that includes the brain. All muscles move on commands from the brain because single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles.

For what length of time was the IT Support department able to close down each weekend during Richard's first month?
Nixon's concerns turned out to be valid. The unemployment rate reached a politically harmful 6 percent by the end of 1970.
In that year, Nixon named Arthur Burns as the head of the Federal Reserve. Burns rapidly established his independence by issuing Nixon a challenge: if Nixon failed to maintain federal spending under $200 billion, Burns would continue to keep the money supply constrained in an effort to combat inflation. Nixon complied with Burns' requests. He put off government employees' salary raises by six months in order to conserve money. One outcome was a nationwide postal employees' strike. Nixon employed the U.S. Army to keep the postal service operating, but in the end, he carved into postal workers' salary demands, erasing some of Burns' budget-balancing requirements.

why the food pyramid is wider at the base and very narrow at the top
Answer:
The wider base stands for foods with little or no solid fats or added sugars. These should be selected more often. The narrower top area stands for foods containing more added sugars and solid fats. The more active you are, the more of these foods can fit into your diet.
Explanation:
A food pyramid can be defined as a graphical representation of a set of dietary guidelines and optimal number of servings from each of the basic food groups, which are to be eaten daily by an individual.
Basically, a food pyramid illustrate the principles of good nutrition and contribute towards a healthy balanced diet.
Foods and drinks that are highly rich in nutrients such as fruits and vegetables are found at the wider base (bottom) of the food pyramid while foods that are high in sugar, cholesterol, salt and fat are placed at the top.
In conclusion, the food pyramid is wider at the base because that is where all the very good and nutritious foods are illustrated while it is very narrow at the top because those are unhealthy foods and drinks for humans.

Why do the cells of the digestive system secrete proteolytic enzymes, such as pepsin, in their inactive forms
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

Which of the following explains how photosynthesis takes place in a plant?
Answer:
D
Explanation:
Carbon dioxide enters through the stomata on the underside of the leaf.
Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.
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).
Oxygen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.
If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?
Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.

How to illustrate the information?Important water qualities like adhesion and cohesion have an impact on how water behaves everywhere, from plant leaves to your own body. In Adhesion, W
water is drawn to other substances, while in cohesion, water is drawn to different types of water.
The force that draws molecules of the same substance together is called the cohesive force. The force that holds molecules of various substances together is known as the adhesive force.
Therefore, the properties of water that explain why it can be so destructive in heavy rains or floods is cohesion and adhesion.

Answer:
D. 3H2O
Explanation:
An atom is the smallest unit of matter that has the characteristics of a chemical element. It consists of protons, neutrons, and electrons - small electrically charged particles.
They make up molecules - electrically neutral groups of two or more atoms connected by chemical bonds. Multiple molecules that consist of two or more different atoms make up a chemical compound.
The chemical compound that has nine atoms is 3H2O. Here, we have three molecules of water. Each molecule consists of three atoms - two hydrogen atoms and one oxygen atom. This means that three of these molecules have a total of nine atoms.

The order of fermentation rate using these substrates is arranged from highest rate to lowest (left to right) Glucose---sucrose---fructose--starch True False
Answer: Its true
Explanation: The order of fermentation rate using these substrates is arranged from highest rate to lowest (left to right) Glucose---sucrose---fructose--starch True False
It is true that the order of fermentation rate using these substrates is arranged from highest rate to lowest Glucose, sucrose, fructose, and finally starch.
What is fermentation?Fermentation is a biological process that involves the action of enzymes to produce chemical changes in organic substrates.
It is narrowly defined in biochemistry as the extraction of energy from carbohydrates in the absence of oxygen.
Fermentation is a chemical process that breaks down molecules such as glucose anaerobically.
Fermentation is a chemical process that breaks down carbohydrates such as starch and glucose anaerobically.
Fermentation has numerous health benefits and is used to make alcoholic beverages, bread, yogurt, apple cider vinegar, and other products.
Fermentation serves many purposes, including adding new flavors and textures to food, extending food shelf life, making some nutrients more easily absorbed by the body, and providing a habitat for probiotics to grow and reproduce.
The fermentation rates for these substrates are listed in the following order: glucose, sucrose, fructose, and finally starch.

What general name is given to tracts that connect the right and left cerebral hemispheres?
An object is subjected to an unbalanced force. What happens to the object
A- The object changes speed or direction.
B- The object continues moving at a constant speed.
C- Nothing changes.
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.
When an object experiences an imbalanced force, the item either alters its speed or its motion's direction.
Option A is the proper response, thus.
What is the second law of Newton?The resultant force exerted on an object is proportional to the rate of change of momentum, according to Newton's Second Law.
Force is equal to the product of an object's mass and acceleration because acceleration is the change in velocity expressed by either a change in speed or a change in direction.
One of two things occurs when an item encounters an imbalanced force: either the object alters its speed or its motion direction.
As a result, choice A is the right response.
