Together, the stages of cellular respiration break down one molecule of ___ to generate a total of ____ molecules of ATP. The remaining energy is released as __ .
Answer:
1) Glucose
2) 36
3) Heat
Explanation:
Cellular respiration is a metabolic process that every living organism undergo. It is the process by which energy is obtained by living cells. In the process of celluar respiration, energy-storing food molecule called Glucose is broken down in the presence of oxygen in order to release its energy and convert it to a usable form by the cell called ATP.
Celluar respiration occurs in three distinct stages in eukaryotes viz: Glycolysis Kreb's cycle and Oxidative phosphorylation. In Glycolysis, which occurs in the cytoplasm, glucose is broken down in a series of enzymatic reaction to yield Pyruvate and releasing a net gain of 2 ATP molecules. In Kreb's cycle, which occurs in the mitochondrion, produces carbondioxide in a two-cycled reaction involving Pyruvate. 2 ATPs are also produced in this stage.
Lastly, in Oxidative phosphorylation also occuring in the mitochondrion, electrons are passed through electron acceptors to create a pump that generates the synthesis of 32 ATP molecules. In general, the three stages yield a total of 36ATP molecules from one molecule of GLUCOSE.
The rest of the energy from the oxidation of glucose is lost as heat energy, which is responsible for the warming effect we feel.
Which of the following statements is true? Stem cells can only be obtained by destroying embryos. Stem cells can be obtained from the brain and other tissues in healthy adults. Stem cells are unobtainable because they can't be kept alive in lab conditions. Stem cells can be produced artificially.
Answer:
Stem cells can be obtained from the brain and other tissues in healthy adults.
Explanation:
Now research is showing that these stem cells can actually be obtained throughout the brain or other body tissues.
Stem cells can be obtained from the brain and other tissues of healthy adults by a mechanism of induced pluripotent stem cell (IPSC). The second statement is the correct one.
What is a stem cell?
Stem cells are present in the body and can form either a single type of cell or multiple kinds of cells. The zygote is an example of a stem cell because it divides to form various types of cells such as the heart cell, lung cell, nerve cell, and so on. This is called a totipotent stem cell, which can form all types of cells.
As the embryo grows, the totipotent nature of cells is lost, and they become pluripotent. Pluripotent stem cells can differentiate to form a wide range of organs such as the lungs, heart, etc.
These cells are further specified as being multipotent stem cells. These stem cells can only form a particular range of cells, such as hematopoietic stem cells. This stem cell can only form blood cells.
A mature cell from the body can be taken and chemically induced to be a pluripotent stem cell (IPSC). Stem cells can't completely form in a lab as they require a lot of signalling molecules.
Hence, stem cells can be obtained from the brain and other tissues of a healthy adult.

Based on the information in the graph, what conclusions can be drawn about the rate of skin cancer in men
compared to that in women?
than in women
Answer:
The correct answer is - Skin cancer increased at a faster rate in men than in women.
Explanation:
Skin malignant growth is the most well-known disease in the entirety of mankind. Although white and albino skinned person individuals have a more possibility of building up this malignancy, consistent exposure to the sun with no skin security has caused an expansion in instances of skin disease regardless to the person's skin shading.
In spite of being a typical disease in ladies, skin malignancy has been developing exponentially among men as of late. This is primarily on the grounds that ladies will in general take more consideration of their skin and ensure it more regularly than men.
Thus, the correct answer is - Skin cancer increased at a faster rate in men than in women.

For example; _____is a general-purpose, non-selective growth media, _____is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and _____are selective agar for Gram positive organisms and ______agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, and _____is an example of a liquid that supports growth of a variety of organisms.
Answer:
Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; Nutrient agar is a general-purpose, non-selective growth media, Chocolate agar is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and Mannitol Salt agar are selective agar for Gram positive organisms and MacConkey agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, Nutrient broth is an example of a liquid that supports growth of a variety of organisms.
Explanation:
Growth media are classified based on their composition as:
1. General Purpose Media: These type of media support the growth of non-fastidious organisms, that do not require special nutrients for growth, and they also serve as a base for certain modified media. An example is the nutrient agar
2. enriched media: these media, like the name implies, is one that has been modified by the addition of special growth factors and nutrients called enrichment. An example is chocolate agar where lysed blood is added to nutrient base agar, when the blood cells are lysed slowly at 80°C, nicotinamide adenine dinucleotide (factor V or NAD) and hemin (factor X), are released into the medium, and these support growth of certain fastidious organisms like Haemophilus influenza bacteria.
3. Selective media: These kinds of media contain substances that support the growth of certain organisms while in turn preventing the growth of others due to the presence of certain inhibitory factors. Examples are: Mannitol Salt Agar, which supports growth of Gram-positive organisms and MacConkey agar, which supports the growth of Gram-positive organisms
4. Non Selective media: These type of media have no biases against the growth of certain organisms, that is, they do not contain certain inhibitory factors that impede the growth of certain organisms.
5. Differential media: These media contain chromogenic agents that change colour and helps to differentiate one organism from the other, making for ease of identification especially for organisms with similar properties.
Finally, a broth is a growth medium that fo not contain agar, hence, it is liquid and not solid.

2. A mirror works by __________the light that hits
Answer:
1.A _shadow_ is formed when an _ transparent _ object blocks the path of light
2. A mirror works by _reflecting_the light that hits
Explanation:

In response to high amounts of phosphate transport into the cell: a. PhoR is phosphorylated by the phosphate transporter protein Pst b. PhoR binds with PhoB to remove PhoB repression of phosphate regulon genes c. PhoR is exported out of the cell to scavenge phosphate molecules d. PhoU changes conformation to allow PhoR to autophosphorylate e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Answer:
e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Explanation:
PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.

In a species of chickens, incomplete dominance between alleles for black (B) and white(w) feathers
is observed. Heterozygotes are blue.
• If two blue chickens are crossed, what is the probability that the offspring will be blue.
Answer:
1/2
Explanation:
This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.
According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, BW and WW in the ratio 1:2:1
BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.
