Six white-tailed deer and six sika deer were enclosed in a pasture for observation during an eight-year study in central Texas. White-tailed deer are a native species to central Texas, while
sika deer are a nonnative species to central Texas. White-tailed deer feed on flowering plants and the tips of trees and shrubs but do not eat grass. Sika deer feed on flowering plants, the
tips of trees and shrubs, and grass. All other grazing animals were kept out of the pasture during the study. The number of sika deer more than doubled after the eight years, while the
population of white-tailed deer decreased by 50 percent.

If PCBs escaped into the river in large amounts and entered the lower levels
of the food chain, what would be the likely outcome?
Answers
Answer:
Over time, PCBs would collect in top predators such as salmon, making them unsafe for human consumption.
Explanation:
PCBs last a long time in the environment before breaking down and may find their way into the food chain. Low levels of PCBs can be found in fish, shellfish, meat, poultry, milk, dairy products, and other foods. Since PCBs have not been made since 1977, the levels in the environment have been declining over the past several years. Predators at or near the top of the food chain (e.g. birds, fish) have the highest levels of PCBs in their bodies.

Explain how mutated DNA would produce proteins responsible for sickle cells rather than producing proteins responsible for normal red blood cells
Answers
Answer:
Explanation:
Sickle cell anemia is a result of the point mutation, and in a change in just one nucleotide in a gene for hemoglobin. This mutation will cause the hemoglobin in the red blood cells to distort to a sickle shape when deoxygenated. "The sickle-shaped blood cells clog in the capillaries, cutting off circulation."

Which process connects glycolysis and the citric acid cycle?
lactic acid formation
acetyl CoA formation
electron transport
Krebs cycle
Answers
The process which connects glycolysis and the citric acid cycle is acetyl CoA formation.
GlycolysisGlycolysis is the reaction pathway busy which a glucose molecule is converted to two pyruvate molecules with the production of two net ATP molecules.
Citric acid cycleThis is a cyclic reaction pathway in which a mole of acetyl CoA is oxidized to two molecules of carbon (iv) oxide with the production of the reducing equivalents NADH and FADH2 as well as two ATP molecules.
Acetyl CoA formationThe pyruvate from glycolysis is oxidized to an acetyl CoA molecule by the pyruvate dehydrogenase complex. The acetyl CoA produced then enters the citric acid cycle.
Therefore, the process which connects glycolysis and the citric acid cycle is acetyl CoA formation.

What is the molecule depicted in the figure above and in which organelle would it most likely be created?
A. ATP, the mitochondria
B. ATP, the nucleus
C.ADP, the chloroplast
D. ADP, the ribosome
Answers
Answer:
The answer is A.
Explanation:
ATP, the mitochondria
The molecule depicted in the figure above is ATP and the cell organelle in which it would most likely be created is: the mitochondria.
Cell organelles can be defined as the internal organs that are typically responsible for the performance of various functions (tasks) within the body of a living organism such as an animal, plant, and humans, especially for the survival of the organism.
Some examples of cell organelles found in the body of living organisms include the following:
Nucleus. Cytoplasm. Cell membrane. Chromosome.Endoplasmic reticulum (ER). Golgi apparatus (bodies).Vesicles.Mitochondria.Mitochondria is commonly referred to as the "power house" of a cell because it is saddled with the responsibility of providing and transforming all of the energy required by living organisms in the form of adenosine triphosphate (ATP).
In conclusion, it is very important that energy (ATP) is provided by mitochondria for the survival and optimum performance of a living organism.

What process allows Na+ and K+ to move in and out of the cell simultaneously?
ANSWERS:
A.Simple Diffusion
B.Facilitated Diffusion
C.Active Transport
D.Osmosis
Answers
Answer:
The correct answer is: C. Active Transport.
Explanation:
Because Na+ and K+ are ions, which makes them charged molecules, they can only diffuse through the cell membrane when using specialized protein channels. This is called facilitated diffusion and is a form of passive transport because sodium and potassium move following their gradients, which are made of the difference in concentration between the inside of the cell and the outside of the cell. For example, potassium is highly concentrated inside the cell and poorly concentrated outside the cell, so potassium diffuses from the inside to the outside to even the concentrations.
But the question asks in which process Na+ and K+ move in and out of the cell SIMULTANEOUSLY, so the answer is actually active transport. Active transport is the opposite of passive transport. While passive transport occurs naturally and doesn't need ATP (energy) to happen, active transport needs ATP because it moves molecules AGAINST their gradient. One of the most famous and important structures involved in active transport is the Na+/K+ pump, which consists of a specialized protein using energy to enter 2 potassium ions and take out 3 sodium ions at the same time. This Na+/K+ is fundamental to maintain the gradients, which are important for the correct functioning of many cells.
