Answer: C
Explanation: A good experiment does everything it can to eliminate confounding, or the influence of external sources on the data being measured. Orange juice could be a factor that plays a role in curing the symptoms, so provide a group with and without orange juice gives you the ability to show that the influence of orange juices didn’t have an effect on the cold, or did, but it gives you a baseline to show the effects of the medicine with and without orange juices.
why are there earthquakes
Answer:
Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake. The earthquake starts at the focus, with slip continuing along the fault. The earthquake is over when the fault stops moving.

Answer:
There should probably be some proof in the information above, but the mass would be lost through excretion, respiration, sweating, and movement
Explanation:
Answer:
Ok, in the diagram it looks like there are arrows pointing to its mouth and its rear end right so my best guess would be that the rabbit eats the food, some of the mass is turned into energy and the rest of it goes out the rear end. I'm assuming they want you to explain how mass is turned into energy and travels throughout the body.

Mitosis maintains chromosomes in each {blank} while meiosis maintains chromosome number in the {blank}.
Answer:
Mitosis maintains chromosomes in each cell division constant, while meiosis maintains chromosome number in half
Explanation:
Mitosis maintains chromosomes in each daughter cell while meiosis maintains chromosome number in the gametes.
What is mitosis and meiosis?Mitosis is the process by which a cell divides into two identical daughter cells, each with the same number and type of chromosomes as the parent cell. During mitosis, the cell's DNA is replicated, and the replicated chromosomes are evenly distributed into the two daughter cells. This ensures that each daughter cell receives a complete set of chromosomes, maintaining chromosome number in the daughter cells.
Meiosis, on the other hand, is the process by which a cell divides into four non-identical daughter cells, known as gametes. During meiosis, the cell's DNA is replicated, and the replicated chromosomes are shuffled through a process called crossing over. This shuffling results in gametes with unique combinations of chromosomes, which helps to maintain chromosome number in the gametes. Gametes, also known as sex cells, are the cells involved in sexual reproduction, and they are important for maintaining chromosome number in offspring.

Answer:
1.A
2.C
3.D
4.C
5.A
Explanation:
1.There are some characteristics that are inherited from your parents, shape of blood cells is one of them. In sexual reproduction, offspring are formed when sperm of male combine with egg of female organism.Therefore, some characteristics comes from male organism and some from female organism. In sexual reproduction, diploid organism is formed because half of genes comes from male and half comes from female.
2.Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents
3.A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredit
4.Mendel made sure to study 30,00 pea plants when he presented his data to the community. Another example is when Mendel painstakingly removed all of the immature anthers from the plant’s flowers before the cross.Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
5.A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant

what types of solute molecules may be moved by facilitated diffiusion
Explanation:
Facilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins.
Construction of a new road system splits a population of a rare snail species into three sub- populations, J, K and L. Each of these populations is reproductively isolated.
The table shows the sizes of the three populations immediately after the building of the road
and again ten years later. DNA analysis was used to find:
p the relative frequency of the dominant allele of a gene
q the relative frequency of the recessive allele of this gene.
The three areas of habitat remained the same as each other over the ten year

Which of the following adaptations helps alpine animals survive the cold winter? a. Reduced lung size b. Low levels of hemoglobin c. Hibernation d. Large legs, ears, and tails.
Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.
Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.
This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).
The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.

Gel electrophoresis allows molecules to migrate along the gel at different rates by using:
Answer:
Agarose gel or Pores in the gel
Explanation:
This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.
So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.
