What concept does Hubble's Law most concern?
A. energy lost over time across the universe
B. growing distance between galaxies
C. how stars recycle energy and matter
D. how the universe will eventually end
Hubble's Law most concern with growing distance between galaxies. Thus option B is correct.
What is Hubble's Law ?Hubble’s law refers to the observation in physical cosmology where the movement of galaxies from the Earth at a speed that are proportional to their distance.
The velocity of the galaxy which is called as the redshift.
This laws study physical cosmology and is also known as Hubble-Lemaitre law.
After measuring recession velocity one can determine the distance of the galaxy from us by using Hubble’s equation.
Some limitations are; due to intrinsic motion of galaxies, observed velocity gets influenced and Galaxy orbit due to gravitational movements.
Hubble constant is another unit of measurement, which is used for description of the expansion of the universe. It is 160 km/s per million-light-years.
Thus option B is correct.

C. The muscular walls of the stomach act to churn food back and forth.
D. Small molecules, such as glucose, are absorbed into the blood from the small intestine.
Answer:
Saliva in the mouth acts to moisten and break apart food molecules
An example of mechanical digestion that occurs in the human digestive system is saliva in the mouth acts to moisten and break apart food molecules.
What is mechanical digestion?Mechanical digestion entails physically breaking down food substances into smaller particles so that chemical digestion can proceed more quickly.
Chemical digestion involves digestive enzymes further degrading the molecular structure of ingested compounds into a form that can be absorbed into the bloodstream.
Thus, the correct option is A. Saliva in the mouth acts to moisten and break apart food molecules.

How is Uranus similar to Jupiter?
It has rings.
It has no moons.
It has a rocky surface.
It has methane in its atmosphere
.
Uranus and Jupiter both have rings, both have moons, but they are mostly gas planets, and both have some methane. I think id.k if that helped
Uranus is similar to Jupiter in that it has methane in its atmosphere. Therefore, the correct option is D.
What are Uranus and Jupiter?Both Jupiter and Uranus are planets in our solar system. Jupiter, the largest planet in our solar system, is located five planets from the Sun. Uranus, the third largest planet in our solar system, is located at a distance of seven planets from the Sun.
Both planets are gas giants, with atmospheres composed mostly of hydrogen and helium. Their upper atmospheres also include methane gas, which gives them a blue-green colour. However, there are many differences between Uranus and Jupiter. Although they are much less noticeable than Saturn's rings, Uranus has a system of rings and at least 27 moons. Compared to Jupiter, Uranus is smaller and has less mass.
Therefore, the correct option is D.

A 0.1-kg block of aluminum was heated to a temperature of 80°C. It was then placed into 0.5 kg of water with an initial temperature of 20°C. Which statement best describes the initial interaction between the aluminum block and the water?
Answer:
The aluminum block will transfer heat to the water quickly, by conduction.
Explanation:
Aluminum is an excellent temperature conductor, which means that it can absorb heat very quickly, as well as transfer heat just as quickly. In this case, when the aluminum block is heated to 80ºC, the molecules in that block move quickly and start to collide with each other, releasing heat to the surrounding environment. When this aluminum bar comes in contact with water that has a temperature of 20ºC, the moving molecules of the aluminum bar release heat to the water that heats up, while the aluminum bar loses heat, decreasing its temperature. This temperature transmission will take place until the water and the aluminum bar have the same temperature
The hormone that regulates water reabsorption by the kidneys Group of answer choices only increases water permeability in certain portions of the kidney tubules. increases water permeability throughout the kidney tubules. only decreases water permeability in certain portions of the kidney tubules. decreases water permeability throughout the kidney tubules.
Answer: increases water permeability in certain portions of the kidney tubules.
Explanation:
The proximal convoluted tubule is the site in nephron where selective reabsorption of water and electrolytes like sodium and potassium ions occurs. From there water and other substances are reabsorbed and reenter into the circulation. This cause an increase in blood pressure and blood volume. Only the cells of the proximal convoluted tubule are permeable for this reabsorption process and they are stimulated by a hormone named as aldosterone.

B. Exercise decreases insulin sensitivity in elderly women.
C. Insulin sensitivity is at its highest after 50 minutes.
D. Insulin sensitivity increases as exercise decreases.
Answer:
B. Exercise decreases insulin sensitivity in elderly women.
Explanation:
I got the answer correct in a test.
Exercise decreases insulin sensitivity in elderly women.
What is Insulin?
Your muscle cells are better equipped to use any insulin that is present to take up glucose during and after exercise because their insulin sensitivity has risen.
Whether or not insulin is present, when your muscles contract during activity, your cells can absorb glucose and utilise it as fuel.
Depending on how long you exercise for, among other things, will determine how your physical activity affects your blood sugar levels.
Learn how your blood sugar changes as a result of activity. You can better understand the advantages of exercise by monitoring your blood sugar levels more frequently before and after exercise.
