Answer:
38
Explanation:
In eukaryotic cells, the maximum production of ATP molecules generated per glucose molecule during cellular respiration is 38, i.e., 2 ATP molecules from glycolysis, 2 ATP molecules from the Krebs cycle, and 34 ATP molecules from the Electron Transport Chain (ETC). In vivo (i.e., in the cell), this number is not reached because there is an energy cost associated with the movement of pyruvate (CH3COCOO−) and adenosine diphosphate (ADP) into the mitochondrial matrix, thereby the predicted yield is approximately 30 ATP molecules per glucose molecule. In aerobic bacteria, aerobic respiration of glucose occurs in the cytoplasm (since bacteria do not contain membrane-bound organelles such as mitochondria), and thereby, in this case, it is expected that aerobic respiration using glucose yields 38 ATP per glucose molecule.
Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor in order to signal a target cell to change its behavior. These are examples of hydrophilic hormones in animals: A. tyrosine-derived epinephrin and norepinephrin B. insulin and glucagon C. serotonin and melatonin (tryptophan-derived mammalian neurotransmitters D. All of the above E. None of the above
Answer:
The correct answer is - D. all of the above.
Explanation:
Hydrophilic hormones are the hormones that can not pass through the cell membrane as they are poorly lipid-soluble and cannot pass through cell membranes and bind the receptors present on the surface of the membrane.
Insulin and glucagon are peptide hormones that bind to a receptor in the target cell's membrane surface. Norepinephrine and epinephrine are catecholamines that are hydrophilic in nature. Seratonin and Melatonin are also bound on the surface receptor due to their hydrophilic nature.

Explanation:
What impact of climate change is presented in the given article?
Answer: Ice caps melting
Explanation:
The article talks about the climate change effect of the ice at the poles melting. The ice is very important because it reduces heat by reflecting some of the sun's rays.
If the ice melts as it is continuing to on account of global warming, temperatures would rise as well as water levels as a result of the ice being unable to reflect the sun's rays and melting into the ocean.
how does the method of obtaining energy for fungi differ from that of plants and animals?
Answer:
From animals they need energy to get it fungi they can make it
Explanation:
Answer:
Fungi obtain their energy from absorbing either dead or living organisms.
Explanation:
Fungi are heterotrophic, meaning they cannot produce their own food, unlike plants. Plants are able to perform photosynthesis to obtain their energy by converting carbon dioxide and water into oxygen and glucose. However, unlike animals who go out to either hunt or forage food (for example, a deer eating grass or a wolf hunting a bunny), fungi absorb nutrients from dead or living organisms. For example, a fungi might be seen next to a decaying oak log. Or, it might be seen on the bark of a living tree.
The subject of a source can best be described as themain topic or area of concern.most important idea in the text.tendency to view something in a certain way.way the source wants people to feel or think.
Answer:
main topic or area of concern.
Explanation:
An information source can be defined as a system or medium through which informations, knowledge and ideas may be gotten and used by an individual. An information source can either be a primary or secondary source of information. The source options for informations are television, radio, web, newspapers, journals, magazines etc.
The four criteria used to evaluate source options are;
1. Accuracy: the user of this source of information should check if the data presented are accurate and credible. At this point, you should ensure that the informations provided are well researched and cited for verification.
2. Authority: you should endeavor to know who the author and publisher of the information source is. Also, it is important to know their qualifications.
3. Currency: it is necessary to know when the information source was created or produced by the author. Also, the user of this data should verify when it was published (in the case of a book) or if it requires an update (in the case of a website). Hence, the information source should be timely.
4. Objectivity: ensure that the source of information is unbiased, reliable, and should not only contain opinions but facts.
Basically, the subject of a source can best be described as the main topic or area of concern.

How can embryos be more useful than adults to show evolutionary relationships among organisms?
Select one:
Related organisms always appear identical in embryonic stages.
Adults may have mutations that are not found in embryos.
Evolutionary relationships are more easily observed in more simple organisms.
Features found in embryos may not be found in adults.
Answer:
Related organisms always appear identical in embryonic stages.
Explanation:
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor. Thus, embryology is frequently used as evidence of the theory of evolution and the radiation of species from a common ancestor.

Pablo’s blood type is B+ while his mother’s blood type is O-. Which are the potential blood types of his father?
Answer:
the father may be BB++ BB +- BO ++ or BO +-
Explanation:
The blood type is a monogenic inherited trait that has three different alleles: A and B alleles are dominant, while the O allele is recessive. Each parent donates one ABO allele to their offspring. On the other hand, the Rh factor single gene inherited trait that has two alleles: the Rh-negative (-) factor is recessive to the Rh positive (+). Each parent donates one Rh factor allele to their offspring. In this case, the mother has the genotype OO -- (recessive for both genes), while Pablo has a phenotype of B+ and a genotype BO+- (i.e., Pablo is heterozygous for both genes). In consequence, the father may have the following genotypes: BB++ BB +- BO ++ or BO +-, from these combinations you could get a son with the genotype BO+- .
how can we differentiate between strong and weak acids using indicator?
Answer:
simple...
Explanation:
If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid

The difference in the chromosome arrangement during meiosis in the metaphase plate can lead to greater genetic diversity in a population. Explain your answer
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis. For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.

Explain the effect of the fungi on the growth of the seedlings after they emerge.
Answer:
The most common pattern is where the cotyledons are raised above ground as the seedling emerges. The seedling forms a hypocotyl hook that pushes through the soil. Once the seedling reaches the light, the hook opens to create a straight seedling. ... The cotyledons function as the repository for food reserves in the seed.
