1. Analyze Less than 20% of the Nahmint and Nanaimo Rivers were stocked with
captive bred salmon. Was there a decrease in egg size in these rivers?
Answers
Answer:
Captive breeding and release programs, widely used to supplement populations of declining species, minimize juvenile mortality to achieve rapid population growth. However, raising animals in benign environments may promote traits that are adaptive in captivity but maladaptive in nature. In chinook salmon, hatchery rearing relaxes natural selection favoring large eggs, allowing fecundity selection to drive exceptionally rapid evolution of small eggs. Trends toward small eggs are also evident in natural populations heavily supplemented by hatcheries, but not in minimally supplemented populations. Unintentional selection in captivity can lead to rapid changes in critical life-history traits that may reduce the success of supplementation or reintroduction programs.

In which situation would water enter a cell through osmosis?
A.The cell is 20% water, and the cell's environment is 80% water,
B.The cell is 50% water, and the cell's environment is 50% water,
C.The cell is 60% water, and the cell's environment is 40% water.
D.The cell is 80% water, and the cell's environment is 20% water.
Answers
Answer:
A
Explanation:
Water enters osmosis when the cell's water is lower than its environment's water. This is known as Hypertonic. B is an equalibrium so nothing special happens there, and C and D are examples of potential bursting of the cell from too much water, known as Hypotonic, so in process of elemination, A would be the answer. Another way of telling that C and D aren't the answer is that if they were really true, both of them would be correct, and there can't be two correct answers.
Water would enter the cell if the cell is 20% water, and the cell's environment is 80% water (Option A).
Osmosis refers to the process of movement of a solvent (e.g., water) from a solution of lower concentration to a solution of higher concentration through a semi-permeable membrane.The osmosis movement tends to balance the final concentrations of solute on the two sides of the membrane.This process (osmosis) is called passive transport because it does not require energy to move water molecules through biological membranes.In conclusion, water would enter the cell if the cell is 20% water, and the cell's environment is 80% water (Option A).

The graduated cylinder has been the laboratory equipment that is used for measurement purposes. The volume of the liquid in the cylinder is 24 mL. Thus, option B is correct.
What is a graduated cylinder?A graduated cylinder is defined as equipment made either of glass or plastic used to measure the substances and chemicals in the laboratory. They are also referred to as mixing cylinders or measuring cylinder that mixes and measures the chemicals.
They measure the volume of the liquids and are made in glass and plastics that look long and cylindrical in shape that is also marked externally with various markings that differ in various units and scales.
The exact quantity or volume of the liquids is measured by looking at the lower meniscus level of the curve formed in the graduated cylinder. Here, the scales are marked as 20, 22, 24, 26, 28, 30, and so on. The lower meniscus of the liquid is at 24 mL.
Therefore, in option B. the volume of liquid is measured to be 24 mL in the graduated cylinder.

Describe the famous experiment related to gravity that Galileo may have preformed. Include the results. Also, state whether the results support the law of gravity. Explain your answer.
Please help me please and thank you Id appreciate it very much.
Answers
According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time,
Answer:
Galileo threw two balls from a tower's summit. They were both the same size and shape, yet one weighed 50 grams and the other weighed 500 grams. As a result, the two balls collided at precisely the same time. This finding backs up Newton's law of gravitation, which states that things with more mass will be subjected to a larger gravitational force. Because the 500-g ball has higher inertia, it takes more force to accelerate it. That force is provided by the stronger gravitational pull, and the two balls descend at the same rate.

which of the following statements about blood is false?

b. red blood cells circulates for about 120 days
C. when red blood cells are destroyed the iron component of hemoglobin is preserved for reuse
Answers
Answer:
a. individuals with type AB blood can only receive a transfusion of type AB blood
Explanation:
Type AB blood can receive transfusion from all the other blood types (A, B, AB and O). This is why, it is considered to be the universal recipient. Thus, this makes choice a false.
On the contrary, the universal donor among the blood types is type O blood. This means that a person with this type of blood can donate to all types of blood because it is compatible. However, it can only receive transfusion from the same blood type O.
Mitosis is a part of interphase in the cell cycle.
true
false
Answers
Answer:
False
Explanation:
Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle.
Mitosis is a part of interphase in the cell cycle. The given statement is False.
What is mitosis?Mitosis is also termed as equational division. It is defined as a type of cell division where the chromosomes are replicated and are equally distributed into two daughter cells.
Mitosis is not a part of interphase in the cell cycle. Interphase is the phase of the cell cycle that occurs between cell divisions, and it includes three sub-phases: G1, S, and G2. During interphase, the cell grows, replicates its DNA, and prepares for cell division.
During mitosis, the replicated chromosomes are separated into two sets and the cell divides into two daughter cells. Mitosis is a critical process for the growth, repair, and maintenance of multicellular organisms. Therefore, the given statement is False.

does a haploid cell for that organism have?
32

16
Explanation:
A diploid is the combination of 2 sets of chromosomes, a haploid would be half which in this case would be 16, We know that 2 haploids make a diploid so if the diploid cell has 32 chromosomes then half of it would be 16 which would be the amount you will find in the haploid, hope that makes sense
The rate of respiration (how fast you breathe) is determined by which amount of gas in the blood? A.Oxygen b.Nitrogen c.Carbon Dioxide d.None of the above
Answers
Answer:
c. Carbon Dioxide
Explanation:
The rate of respiration is determined by the presence of concentration of carbondioxide gas in the blood because in the process of respiration, energy in the form of adenine tri phosphate (ATP) and carbondioxide gas are produced. This ATP is required for performing different activities while carbondioxide gas is a waste product which must be removed from the blood through breathing. If carbondioxide gas is produced quickly so the rate of respiration is also increased in order to remove the gas from the blood.

Explanation:
cell division occurs in two stages division of the nucleus called ___ and division of the cytoplasm called ___
Answers
Cell division occurs in two stages: division of the nucleus called mitosis, and division of the cytoplasm called cytokinesis.
What is cell division?Cell division is the process by which a parent cell divides into two or more daughter cells. The two main types of cell division are mitosis and meiosis. Mitosis is the process by which a cell divides its chromosomes equally between two identical daughter cells, resulting in cells with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, is a type of cell division that reduces the number of chromosomes by half, resulting in cells with half the number of chromosomes as the parent cell. This is important for sexual reproduction, as the chromosomes from each parent combine to form new combinations in the offspring.

2-deoxyglucose poison has its effects during glycolysis, which only produces 2 ATP, while Cyanide takes place during ETC which produces 34. If given the 2-deoxyglucose poison this would stunt the rest of the process very early on, so much so that no ATP could have been produced. So the ATP concentration would have decreased if given the other poison.
