Question:
Using a specific example, discuss the importance of electrons in the transfer of energy in living systems.
Answer: The transfer of energy in the form of electrons allows the cell to transfer and use energy in an incremental fashion. The principle electron carriers are NAD+ and NADH because they can be easily oxidized and reduced, respectively.
Explanation:
Electrons are very significant in the steps of energy transfer in the living body cells.
When the electrons are displaced from the molecule it gets oxidized which results in a reduction in the potential energy.
Electrons transfer is very important because most of the power is stored in the atoms in the form of electrons that are required for cell functioning.The chief electron transporters are NADH and NAD⁺ they reduce and oxidizes the compounds.NAD⁺ is oxidized and NADH is the reduced form of the molecules.The living structures cannot save a large amount of energy and hence they collect them in the form of ATP and electrons.To learn more about the importance of electrons in living organisms follow the link:

II. Support the body
III. Protect the internal organs
IV. Make the eggs
I and II
II and IV
I and IV
II and III
Answer:
c
Explanation:
I and IV are the functions of the reproductive organs in animals.
What are Reproductive organs?
The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
The fertilized egg is then transferred to your uterus, where the lining has expanded due to the regular hormones produced during your menstrual cycle (also called your reproductive cycle).
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur. The female reproductive system also creates sex hormones that keep your menstrual cycle regular.
Therefore, I and IV are the functions of the reproductive organs in animals.

What happens if the mass of the elements is greater compared to smaller ?
Hello. More information is needed to answer your question accurately. However, I will try to help you in the best possible way
If you are referring to what happens if the mass of an atom is greater compared to an atomic number, we can say that there is nothing too much, since it is normal for the atoms to have a mass slightly greater than the atomic number. The mass of an atom can never be less than the number of protons added to the number of neutrons. An atom with greater mass has a greater number of electrons and neutrons in relation to an atom of less mass and it is likely that the atom of less mass will donate or share electron with the atom of greater mass so that both reach the electric balance.

Most of the traits expressed in a person's phenotype are determined by is Phenotype.
What is Phenotype?Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe."
It can therefore refer to anything from a common attribute, like height or hair color, to the presence or absence of a disease. It is also an observable type of an organism.

How might a wildfire influence mass wasting? By drying out (removing the water) from the regolith on a slope, wildfires decrease the likelihood of a mass wasting event. A wildfire can dry out the regolith on a slope, making it less cohesive and more likely to travel downward. Wildfires burn only at the bottom of a slope, which oversteepens the slope and induces mass wasting. The ash from the wildfires lands on the slope, adding enough mass to instigate mass wasting. Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Answer:
Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Explanation:
The plants present in a region, protect the soil from being eroded by the impact of rain or wind. This is because the roots of the plants leave the soil more aggregated, block the impact of the wind and allow water to infiltrate. This protection is increased on slopes, where the chances of erosion are greater. However, when a fire occurs and these plants are killed, the roots no longer provide protection to the soil, leaving it drier and looser. This causes the wind to break this soil apart, facilitating erosion. In addition, rainwater has difficulties in infiltrating the soil and ends up draining, taking parts of the soil with it and causing erosion.

3. L. in both the mitochondria and the cytoplasm, and requires energy.
4. J. an increase in the activation energy for the pathway.
5. K. donor, and divide by mitosis.
Explanation:
The sources of genetic variation in a population with sexual reproduction are 1-mutation, which can be defined as genetic changes in the genome of an organism that create new alleles in the population, 2-independent assortment, where pairs of homologous chromosomes are randomly separated, during meiosis, 3-fertilization, where two gametes held together to form the zygote cell (thereby creating new genetic combinations), and 4-recombination or crossing over (i.e., the exchange of genetic material between non-sister chromatids during meiosis). Endocytosis is a cellular process by which substances enter into the cell by invagination of the cell membrane (this term is contrary to exocytosis). In eukaryotic cells, mitochondria are organelles whose membranes produce ATP from ADP and Pi by aerobic respiration (i.e., by the Krebs Cycle and electron transport chain), while glycolysis occurs in the cytoplasm. This process requires the addition of energy (chemical energy in the form of organic compounds). An energy pathway that has many small regulated steps is expected to produce intermediate products and increase its activation energy. Finally, stem cells that derive from a donor and are genetically identical it is expected that divide by mitosis.

List advantages and disadvantages of using scientific models.
Answer:
Explanation:
disadvantages:
Models do not behave exactly like the things they represent. Accuracy—In order to make models simplistic enough to communicate ideas some accuracy is lost. For example, ball and stick models of atoms do not show all the details that scientists know about the structure of the atom.
advantages:
When students are engaged in scientific modeling, they are able to notice patterns and develop and revise representations that become useful models to predict and explain--making their own scientific knowledge stronger, helping them to think critically, and helping them know more about the nature of science.
The advantage of a scientific model is it allows complicated processes to be predicted and simplified. A model's drawback is that it could be deceptive and open to numerous interpretations.
What is a scientific model?The advantages are:
Students who participate in scientific modeling are better able to identify patterns and create and revise representations that become useful models to predict and explain, strengthening their own scientific knowledge and fostering critical thinking. They also gain a better understanding of the nature of science.The disadvantages are :
Models don't always act the same as the things they're meant to represent. Accuracy—Some accuracy is lost when models are simplified to the point where they can convey concepts. For instance, the specifics that scientists are aware of regarding the structure of the atom are not depicted in full by ball and stick representations of atoms.Thus, the advantage and disadvantages are written above.

Explanation:
Assume that you discover a new human gene that you believe is located on the Y chromosome although not in the region (pseudoautosomal) of the Y that is homologous with part of the X chromosome. How would you map this gene with respect to the other genes on the Y chromosome
Answer:
by performing a bioinformatic analysis in order to discover Y chromosome-linked mutations associated with defective phenotypes. In this case, it is expected to discover two or more loss of function mutations located in the coding region of the target gene on the Y chromosome in different males, and then associate such mutations with altered phenotypes caused by the inactivation (loss of function) of this gene
Explanation:
The genes located on the Y chromosome exhibit a uniparental mode of inheritance (i.e., these genes are only transmitted from father to their sons). This situation makes difficult to map the target gene since recombination does not occur for genes that are only located on the Y chromosome, hampering the development of a linkage map containing this gene. In this case, it is possible to directly associate genetic mutations located at the same genomic region (locus) on the Y chromosome with a particular altered phenotype in males carrying these mutations, which can be in principle associated with the inactivation of the target gene (loss of function mutations) in these individuals.
