Imagine that Yusef had a diet with absolutely no fat. What impact would this have on his overall health?
OPTIONS:
A.
He would have absolutely no energy.
B.
He would more easily absorb nutrients.
C.
He would be unable to absorb vitamins.
D.
He would have a compromised immune system.
PLEASE NO LINKS
Answer:
A.
Explanation:
In addition to helping you lose weight by using calories on more filling foods, following a low-fat diet can help you ward off serious medical conditions, including heart disease, high cholesterol, and diabetes. The body needs some fat to function properly.
If Yusef had a diet with absolutely no fat then He would have absolutely no energy. Hence A is correct option.
What fat do to your body?Fat aids in the body's absorption of vitamins A, D, and E. These vitamins are only absorbed with the aid of lipids because they are fat-soluble. Body fat is created from any fat that is not utilized by the body's cells or transformed into energy.
According to research, the majority of fat cells in adipose tissue are produced by cells that line the blood vessels. This realization might inspire fresh methods for treating and preventing obesity. Our metabolism, reproduction, and life lengths are all regulated by white adiposity, or fat, tissue.
Hence option A is correct.

Theo mixes cake batter and places it in the oven at 350°F for 45 minutes. Explain what type of reaction baking a cake represents in terms of energy.
Answer:
Baking a cake requires heat to be applied to the batter in order for it to cook and chemically change into cake. The energy or heat applied is absorbed by the ingredients, so this represents an endothermic reaction.
Explanation:
that's the sample answer, hope it helps
The batter needs to be heated in order to cook and chemically transform into a cake when it is baked. An endothermic reaction is taking place because the energy or heat applied is being absorbed by the constituents.
What is energy?The quantitative characteristic that is transferred to a body or a physical system in physics is referred to as energy. It manifests itself as heat and light, as well as the act of doing work. Energy is a resource that is conserved; it can only be changed from one form to another and cannot be created or destroyed, according to the law of conservation of energy. The SI unit of energy measurement is the joule (J).
According to the question, there are various types of reactions two of which are endothermic reactions and exothermic reactions.
In an endothermic lot of energy is absorbed and in opposition to the exothermic reaction lot of energy is released.

Your thumb contains the only saddle joint in the entire body. How would your hand function differently if your thumb contained a pivot joint? What if it contained a ball and socket joint? Describe four consequences of having a different type of joint in the thumb.
P.S. Detailed Response plz
Answer:
The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.
It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.
The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.
When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.
In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.

Measure a pencil, end to end. Draw a sketch of the pencil and show your measurements. If you were to balance the pencil horizontally on your finger, where do you think it would be balanced? Note this on your sketch, and write down your hypothesis (distance from each end) and your prediction.
Now test your hypothesis. Balance the pencil on your finger horizontally. When it is balanced, your finger is at the center of gravity. Note and make a mark where your finger is in relation to each end of the pencil.
Measure from one end of the pencil to where your finger balanced it. Show this on your sketch, and record the data it in your chart.
Repeat steps b-c a second time for the pencil.
Repeat steps a - d using a pen and crayon as well.
What are your results? Compare your results with your hypothesis and then write an explanation in a conclusion. Which item has a center of gravity closer to the actual center that you measure?
Answer:

An astronaut holds a rock 100m above the surface of Planet X. The rock is then thrown upward with a speed of 15m/s, as shown in the figure. The rock reaches the ground 10s after it is thrown. The atmosphere of Planet X has a negligible effect on the rock when it is in free fall. Determine the acceleration due to gravity on Planet X.
The acceleration due to gravity of the planet X is 1 m/s².
The given parameters;

How does that motion change for the object if the forces on the object are unbalanced?
When the forces on the object are unbalanced, the object will move in the direction of the greater force.
What is Newton's first law of motion?Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force and the object will tend to move in the direction of the applied force.
What is Newton's second law of motion?Newton's second law of motion states that the force applied to a body is directly proportional to the acceleration of the body.
F = ma
Unbalanced forces on a bodyIf the net force acting on a body is greater than zero, the body will tend to move in the direction of the greater force.
Thus, when the forces on the object are unbalanced, the object will move in the direction of the greater force.

Answer:
Magnetic field lines are defined to have the direction that a small compass points when placed at a location.

an audi car advertisement states its car can accelerate from a starting velocity of rest to an ending velocity of 70m/s in 35 seconds. what is the car acceleration?
Answer:
279 m/s
Explanation:
Answer:
2m/s^2
Explanation:
A=(u-v)/t
where u=final velocity and v=initial velocity and t=time
therefore u =70 and v=0 because the question said velocity of rest and finally t=35
so, (70-0)/35= 70/35=2

What is 1.0147 rounded to the nearest thousandths place?
Answer:
1.0147 rounded to the nearest thousandths place is 1.015
Answer:
1.015
Explanation:
If you put the number in place value, you have 1 in the ones place, 0 in the tenths place, 1 in the hundreds place, 4 in the thousandths place, and 7 in the ten thousandths place. In order to know how to round 4, you must look at the number directly after it. Since 7 is greater than five, round up to ten. This increases 4 by 1 which would give you the answer 1.015.
