What is cellular respiration ?
A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.

How is the cell division of cancer cells like these misregulated?
Select all that apply.
Such cells are not inhibited by density.
Such cells can divide in the absence of growth factors.
Such cells skip the G1 phase of the cell cycle.
Such cells do not require anchorage to a surface in order to divide.
Such cells do not respond to signals that normally trigger apoptosis.
Such cells do not need enzymes for DNA replication.
Cancer is due to irregularities in cell division that are caused by mutations in cancerous cells. These mutations inhibit apoptosis and favor cell division. Among the options, the correct ones are 1, 2, 4, and 5.
------------------------------------------
Cancer is the result of irregular cell division.
Its development and progression are closely related to changes in the cell cycle regulator factors.
Cancerous cells
• Divide when they should not do it ⇒ overactivity of the positive cell division regulators.
• Do not stop dividing when they should ⇒ reduction in the activity of cell division inhibitors
• Do not die when they should ⇒ loss of the apoptotic capability
• Leave the area where they are growing ad travel to other parts of the body ⇒ metastasis
Normal cells divide and die during a programmed period.
When a normal cell mutates or suffers from any alterations that can not be repaired, it automatically activates its apoptotic process.
However, cancerous cells lose the capability of dying and their reproductive inhibition, so they keep growing and dividing with no limits.
The unlimited division occurs because mutations in cancerous cells influence the cell cycle by favoring proliferation and inhibiting senescence and apoptosis.
These cells do not depend on external growth factors or other protein signals to divide.
Cancerous cells can release their own growth factor and even influence neighbor cells to produce and release these substances.
Cell division is constant even when there is no space.
Sometimes over multiplication creates tumors that might affect healthy neighbor cells and the tissue itself.
Among the options,
1) Such cells are not inhibited by density. CORRECT
2) Such cells can divide in the absence of growth factors. CORRECT
3) Such cells skip the G1 phase of the cell cycle. INCORRECT
4) Such cells do not require anchorage to a surface in order to divide. CORRECT
5) Such cells do not respond to signals that normally trigger apoptosis. CORRECT
6) Such cells do not need enzymes for DNA replication. INCORRECT

Cancer cells can divide in the absence of growth factors. Cancer cells do not require anchorage to a surface in order to divide. Cancer cells do not respond to signals that normally trigger apoptosis.
Cancer cells can multiply without any growth factors whereas normal cells will not divide without the addition of growth factors. Cancer and tumor cells are less dependent on anchorage. They are free to proliferate, and invade tissues. A normal cell that have damaged DNA will undergo apoptosis while on the other hand, cancer cell with unfixable DNA will not undergo apoptosis and will continue multiplication.

A student collects a sample of water from a pond near her home. She
examines a drop of the water under a microscope and sees four very
differently shaped single-celled organisms. Which of the following
can she reasonably conclude as the reason the organisms look so
different?
Answer:
A. Each organism had a different parent that passed on a set of unique genetic instructions.
Explanation:
Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.
The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.
However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so

Read the excerpt from Part 2 of "The Most Dangerous Game,” by Richard Connell. Then, wet with sweat and aching with tiredness, he crouched behind the stump of a lightning-charred tree. He knew his pursuer was coming; he heard the padding sound of feet on the soft earth, and the night breeze brought him the perfume of the general's cigarette. It seemed to Rainsford that the general was coming with unusual swiftness; he was not feeling his way along, foot by foot. Rainsford, crouching there, could not see the general, nor could he see the pit. He lived a year in a minute. What conclusion can a reader draw about Rainsford based on a visualization of the excerpt? He is relieved. He is lost. He is frightened. He is confused.

what change in a population would you expect to see if a selection pressure was against the traits of the dominant allele?
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

https://brainly.com/question/18592700
Decrease occur in the population of dominant allele occurs.
Change in a population of dominant allele occurs if a selection pressure was against the traits of the dominant allele because the selection pressure is against the dominant allele that leads to appearance of recessive allele and disappearance of dominant allele. The selection pressure is responsible for the appearance of allele in the offspring so we can conclude that dominant allele is decreases in the population of the future generation.
