Answer:
Option -2 Palm oil produces more quantity of oil for a similar amount of land than any other plant is the correct answer.
Explanation:
firstly,
what is palm oil?Edible vegetable oil that is gathered from the mesocarp i.e., the reddish pulp of the fruit of the oil palms is known as palm oil. The oil is used in food manufacturing, making beauty products, and as biofuel.
Palm oil has many advantages that are listed below-
Palm oil is used for preventing aging, cancer, and brain disease and reduces heart disease risk.Oil palm plantation has provided millions of paying jobs and enabled thousands of smallholder farmers to own their land. Palm oil has a long shelf-life and is solid at room temperature, making it an ideal ingredient in a variety of food.Palm oil is used to manufacture sodium lauryl sulfate, which is widely used as a foaming agent(soap) in many body care products for e.g.-soap, detergents, etc.Besides all these positive ways one of the important uses of palm oil farms is that it helps in conserving natural resources.
How do palm oil farms help in conserving natural resources?
Oil palms are significantly more efficient than any other oil-producing crops. A single hectare of land can produce about 4.17 metric tons of sunflower oil, 0.16 tons of ground oil, and 0.39 tons of soybean oil. this means that significantly less land has to clear to meet demands for vegetable oil while other crops require at least five times more land to produce the same volume of oil as oil palms.
Conclusion-Palm oil produces more oil per land area than any other equivalent vegetable oil crops.
hence, the second option that says a similar amount of land produces more oil in the case of palm oil is the correct answer.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because O she did not believe the new formula helped plants grow better than the old formula. O it was necessary to see data from more plants before the conclusion could be accepted. O it was necessary to have tested the fertilizer on different kinds of plants. O she thought he should test additional fertilizer formulas on the same two plants.

Answer:
2. In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
3. Both cellular respiration and fermentation are process that break down food and convert the chemical energy stored in the food to ATP molecules. Both these processes begin with glycolysis and convert glucose to pyruvate. ... Fermentation only uses the latter.
4. Energy is usually absorbed during photosynthesis.
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight(energy source), water and carbon dioxide:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
↑
Sunlight
Sunlight supplies solar energy that is used to converted the chemical species into glucose that stores chemical energy.
Respiration is the reverse of photosynthesis. In this reaction, oxygen gas combines with glucose to produce energy with water and carbon dioxide as by products. The energy stored in photosynthesis is released during respiration.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O ↑ energy

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?
Answer:
Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.
Explanation:
Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.
In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

1-What are some ways in which metamorphosis helps the animals that undergo it?
Answer:
During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. In biology, metamorphosis is the process by which an animal develops continually, after birth or hatching. This involves the change in body structure; both internal and external features, regulated by hormones. Metamorphosis is occasionally accompanied by changes in the animal’s behaviour, physiology and biochemistry.
Explanation:
During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. They change color during metamorphosis as well. The salmon must return to fresh water in order to spawn (breed). Fish that live in the ocean as adults but spawn in fresh water are anadromous. Lampreys go through a period of metamorphosis

Explain how genetic modifications impact crop yield. How will this help feed the world in 2050?
Answer:
The first, which was published in 2014 and included the review of 147 studies, concluded that GM crops have allowed an average increase in agricultural yield by 22 percent and increased farmers' profits by 68 percent, with profit margins even larger in developing countries.Explanation:
An animal that is endothermic and homoeothermic A. uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature B. has its body temperature determined primarily by the environment, but maintains a relatively constant body temperature C. has its body temperature determined primarily by the environment and has a broad range of body temperature variation D. behaviorally regulates its body temperature and has a broad range of body temperature variation E. uses metabolic energy to regulate its body temperature but has a broad range of body temperature variation
Answer: The correct option is A (uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature).
Explanation:
HOMOEOTHERMIC animals are also called endothermic animals. They are the warm blooded animals which uses heat energy generated metabolically to regulate and maintain a relatively constant body temperature. Examples of animals that are endothermic include the birds and mammals.
The temperature which they maintain is deep inside the body and not the skin temperature.
Also the temperature of a body is affected by the heat it gains and losses. The body gains heat mainly:
--> by absorbing it from its surroundings
--> from the heat released during the catabolic reaction that occur all the time in the body cells.
--> by conduction, convection and radiation from the surface of the body
--> through evaporation, especially of sweat and
--> in the air that is exhaled and urine that leaves the body.
Under normal circumstances, the heat the body gains is balanced by the heat it loses. A RISE in body temperature stimulates the following processes to get rid of excess body heat:
--> A decrease in metabolic rate: the body slows down its activities to decrease the metabolic rate. This reduces the heat released by metabolic reactions, hence minimizing heat production within the body.
A FALL in body temperature stimulates the following processes to produce and conserve heat:
--> increasing metabolic rate: The body increases its metabolic rate, especially that of the liver, to produce more heat
