Answer: True.
Explanation:
Glycolysis is a process that occurs in the cell cytoplasm, in which a 6-carbon glucose molecule is cleaved into two 3-carbon pyruvate molecules. Two molecules of ATP (Adenosine triphosphate, a molecule that acts as a source of energy to perform biological processes.) and two molecules of NADH are also obtained. It is a metabolic pathway responsible for oxidizing glucose in order to obtain energy for the cell. It consists of a series of consecutive enzymatic reactions, and when pyruvate is obtained, it continues to be used in other metabolic pathways in order to continue delivering energy to the organism. Glycolysis takes place both in the absence and presence of oxygen, so it is defined as an anaerobic process. Therefore, the final destination of the products obtained in glycolysis will depend on the conditions of the environment in which it is found, which will determine the metabolic pathway to be followed (i.e., whether oxygen is available or not). In the absence of oxygen, glucose will not be completely oxidized to carbon dioxide and water, generating fermentative products (lactic acid in animals and ethanol in yeast) producing only two net ATP molecules. In the presence of oxygen, the pyruvate obtained during glycolysis enters the Krebs cycle (to produce energy in usable form as ATP or GTP) and then undergoes oxidative phosphorylation (the process by which ATP is formed as a result of electron transfer from NADH or FADH2 to oxygen via a series of electron transporters) producing a net gain of between 36-38 ATP.

Cigarette smoke contains carbon monoxide. Explain how this
would affect the normal functioning of red blood cells in a person who
smokes cigarettes.
Answer: Carbon Monoxide is a very harmful and toxic gas which is formed from incomplete combustion of carbon.
Explanation: red blood cells contain haemoglobin ,which are responsible for carrying oxygen into our body system. So oxygen combines with haemagoblin to form oxyhaemogoblin in the red blood cells .
so if a person starts to intake cigarettes which contain high amounts of carbon monoxide ,it reduces oxyhaemogoblin formation because it binds very tightly to the haemogoblin .then carboxyhaemogoblin is formed and its permanent so causing reduction in aerobic respiration, and reduction in oxygen transport and causing damages to heart muscles.

How do somatic and inherited mutations differ?
Answer:
Inherited mutations exist in all cells in the body and somatic mutations only exist in the cell type that mutated.
The accumulation of glucose 6-phosphate inside a bacterial cell via phosphorylation of glucose is an example of:
Answer:
group translocation
Explanation:
Group translocation is a specialized type of active transport that moves substances across biological cells. In group translocation, substrates are chemically modified during transport across the cell membrane. An example of group translocation is the phosphotransferase system, which is used by bacteria for sugar uptake using phosphoenolpyruvate as the source of energy. This system removes the phosphate groups from phosphoenolpyruvate and adds these groups to glucose molecules in order to form glucose 6-P.

Answer:
B. Bald eagles are hunted until near extinction, population recovers
Explanation:
A bottleneck effect can arise when the population of a species is drastically reduced by an occurrence. Human activities plays a major role in regard to creating a bottleneck effect in our present day. Human activities such as overhunting result into bottleneck effect. When overhunting reduces the population of a particular species, the few individuals left would have a reduced genetic variation which is not representative of the original population. The few individuals left further reproduces individuals of their kind carrying a genetic composition that is different from the original gene composition of the old population.
The case of the hunting of bald eagles until near extinction before they begin to recover is a perfect case of the bottleneck effect. Only a small proportion of the eagles original population survives. Generic variation reduces. The genetic variation in the new population of the bald eagles will be different from that of the original population.

This table shows the codons found in messenger RNA (attached). Using this information, what sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Val-His-Thr?
A. GUA-CAU-ACC (THIS IS WRONG)
B. GTA-CAT-ACC
C. CAT-GTA-TGG
D. CAU-GUA-UGG
Please explain, I'm very confused about this topic and I want to learn about it. No false answers or you will immediately be reported. Thanks in advance!
Answer:
A
Explanation:
The correct answer would be option A - GUA-CAU-ACC
Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible
For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.
For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.
Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.
Answer:
A
Explanation:
The correct answer would be that the sperms are changing chemical energy to kinetic energy.
In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells. Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.

QER
Answer:
Provide suitable place, making laws and reduce pollution.
Explanation:
Provide suitable place where they can breed without disturbance, making laws to forbit hunting of endangered species and reduce pollution are the different methods that can protect endangered species of animals and plants around the world. For increase in population, suitable environment is required so that they have no predators or other factor that adversely affect their growth. The laws to forbit hunting or killing has also a significant effect on endangered species. Pollution is the main reason for change in the environment that make the environment not suitable for animals and plants.
Because the flow speed in your capillaries is much less than in the aorta, the total cross-section area of the capillaries considered together must be much larger than that of the aorta. Given the flow speeds noted, the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of approximately what diameter
Answer:
Diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm.
Explanation:
The diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm which is the main reason for higher flow speed of the blood in the aorta as well as more blood is transported in the aorta. If the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of aorta then the flow speed of both is similar due to similar area.

What would most likely happen to this ecosystem if all of the gray wolves were removed?
Answer:
D. The fox population would decrease
Explanation:
The food web shows that the gray wolves population are the only population that prey on the moose population. If the gray wolves were removed, the population of moose would increase significantly and would dominate the ecosystem. This means that other herbivores won't be able to compete with the moose population for the forages and vegetation in the ecosystem. The population of the other primary consumers/herbivores will reduce also. By implication, the fox which depend on other smaller preys to feed on would not have much prey to feed on. The ultimate effect of the removal of the gray wolves would lead to a later decrease in the population of the fox
