Answer:
1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.
2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.
Explain how the lymphatic system is adapted for the transportation of the lymph
Answer:
The lymph capillaries feed into larger lymph vessels. The lymph vessels that receive lymph fluid from many capillaries are called collecting vessels. Semilunar valves work together with smooth muscle contractions and skeletal muscle pressure to slowly push the lymph fluid forward while the valves prevent backflow.
What type of reaction does catalase facilitate- synthesis or decomposition? Why?
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
What is catalase?
An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.
Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.
Numerous industrial uses exist for catalase. It is used with other enzymes in the food industry to preserve foods, make particular dishes and beverages, and preserve foodstuffs.
Therefore, Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

Which celestial objects are formed mostly of the elements hydrogen and helium?
gas giantsgas giants , ,
rocky planetsrocky planets , ,
asteroidsasteroids , ,
dwarf planets
with 75% of their mass being hydrogen and 25% helium.
Celestial objects that are formed mostly of the elements hydrogen and helium are gas giants and dwarf planets. Gas giants are large planets, such as Jupiter and Saturn, which are composed primarily of hydrogen and helium.
What is the reason of calling them Jovian planets ?These planets are also known as Jovian planets, and they are much larger than the terrestrial planets, such as Earth, that are made up of rock and metal. Gas giants have no solid surface and are composed mostly of gas and liquid.
Dwarf planets are smaller than gas giants and are made up of a combination of rock and ice. These objects are too small to be considered full-fledged planets, but they still have characteristics of planets such as an atmosphere, moons, and an orbit around the sun.
Although these objects are composed of different materials than gas giants, they still contain significant amounts of hydrogen and helium. In contrast, rocky planets and asteroids are composed of materials such as rock, metal, and ice. Rocky planets, such as Earth, are composed mostly of iron, silicon, magnesium, and other elements
Hence, . Asteroids are small, rocky objects that are found in the asteroid belt between Mars and Jupiter. These objects are composed of rock, metal, and ice, and contain very little hydrogen and helium.

A. More competition for abiotic factors
B. Less competition for biotic factors
C. An increase in the sustainability of an ecosystem
D. A decrease in the sustainability of an ecosystem
Answer:
The correct answer is - C. An increase in the sustainability of an ecosystem.
Explanation:
Biodiversity is the variety of different biological species and populations on the earth or in an ecosystem. Biodiversity helps in maintaining health by providing food and other resources. Higher biodiversity healthier the earth.
Sustainability is the ability to maintain the ecological process and its structure and function in case of external stress for a longer time. The more sustainability of an ecosystem the healthier the ecosystem. The biodiversity of an ecosystem provides sustainability to the ecosystem. An increase in biodiversity will lead to a more sustainable ecosystem.

7. Pedialyte is a beverage which contains the same concentration of ions (K , Cl-, and Na ) as found in the plasma. Gatorade and Powerade mimic (although are not identical to) Pedialyte. Therefore, we might expect that consumption of Pedialyte should not significantly alter the osmolarity of the blood. How would you expect the urine production rate in the Pedialyte group to compare to that of the water group
Answer:
Less urine production.
Explanation:
The urine production rate in the Pedialyte group is lower as compare to that of the water group because the presence of K, Cl-, and Na ions. The precise combination of electrolytes and sugars in Pedialyte helps in restoring fluid levels and the nutrients in the body that are lost through sweating, urinating, or vomiting and diarrhea. We know that the presence of sodium ions regulation water and electrolyte balance in the body so there is less urine produced by taking Pedialyte group.
The urine production rate in the Pedialyte group to compare to that of the water group -
Pedialyte group - decreased
water group - increased.
The rate of urine output is the urine production in a unit of time. The normal range of urine output is 800 to 2,000 milliliters per day if you have a normal fluid intake of about 2 liters per day.
Drinking Pedialyte increases the ion concentration in the plasma that causes hyperosmolarity. This is sensed by the hypothalamus and releases ADH that leads to more fluid absorption in later DCT and collecting tubules that leads to decrease urine output. On the other hand, if you drink water, hypoosmolarity in blood plasma which does not sense by the hypothalamus and does not release ADH, and the urine output is more than the previous case.Thus,
The urine production rate in the Pedialyte group to compare to that of the water group -
Pedialyte group - decreased
water group - increased.

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 125.6 units of niacin and 5,400 units of retinol. She uses two types of commercial pellet food. Food A contains 0.86 units of niacin and 30 units of retinol per gram. Food B contains 0.66 units of niacin and 40 units of retinol per gram. How many grams of each food does she feed this group of rats each day
Answer:
- 100 grams of food A (x)
- 60 grams of food B (y)
Explanation:
According to this question, the group of laboratory rats are being fed a daily diet of:
- 125.6 units of niacin and 5,400 units of retinol
Let x represent the number of grams needed for food A.
Let y represent the number of grams needed for food B.
This means that:
Food A: Niacin = 0.86x, Retinol = 30x
Food B: Niacin = 0.66y, Retinol = 40y
Since there are 125.6 units of niacin fed to the rats in total, then;
0.86x (A) + 0.66y (B) = 125.6
Since there are 5400 units of retinol fed to the rats in total, then;
30x (A) + 40y (B) = 5400
Solving these two equations simultaneously using elimination method:
0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)
30x (A) + 40y (B) = 5400 ............ (eqn 2)
Multiply eqn 1 by 30 and eqn 2 by 0.86
30 × 0.86x + 0.66y = 125.6
0.86 × 30x + 40y = 5400
25.8x + 19.8y = 3768 ............ (eqn 3)
25.8x + 34.4y = 4644 ........... (eqn 4)
Subtract eqn 3 from eqn 4
14.6y = 876
Divide both sides by 14.6
y = 876/14.6
y = 60
Substitute value for y (60) into eqn 2
30x + 40y = 5400
30x + 40(60) = 5400
30x + 2400 = 5400
30x = 5400 - 2400
30x = 3000
x = 3000/30
x = 100
Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).
Describe the different types of traits that exist.What factors can affect these traits?
Answer:
Cardinal traits, central traits, and secondary traits.
Explanation:
There are three types of traits according to the Gordon Allport which organized traits into three levels that is cardinal traits, central traits, and secondary traits. Factors that affect these traits are the environmental factors as well as genetic factors. Some of these traits acquire by an individual through inheritance while on the other hand, other traits can get by the people through the exposure to environment that leads to the presence of that traits.
She is puzzled that the clone does not have an effect, even though she knows, based on available mutants, that loss of the function of this gene causes worms to die as larvae. You look at the sequence of the DNA she used to make the feeding clone and discover that it corresponds to an intron in the gene. What would you say to the student to explain why her experiment did not succeed
Hello. Your question is incomplete, which makes it difficult to answer, but we can consider that the girl's experiment went wrong because she used a DNA sequence that only corresponds to introns that are not capable of encoding amino acids. Therefore, you could explain to the girl that her experiment did not work, because the introns do not encode amino acids, which prevents the clones from developing proteins that are essential for their survival, since the amino acids are the protein-building molecules .
Introns are important for the control of gene expression, but they cannot encode any amino acid, without which the organism cannot survive.
