All of the following are true of spermatogenesis EXCEPT: Question 4 options: One spermatogonium produces 4 spermatids Genetically diverse spermatids are created. The products are spermatozoa that each have a head, midpiece and tail. DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced.
Answer: The products are spermatozoa that each have a head, midpiece and tail.
Explanation:
The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.

What is the best explanation for the difference in shape between the two drops shown below
Answer:
A
Explanation:
I think the answer is A because Hexane is a non-polar solvent and A is the only answer choice that says its non polar. Im sorry if it is incorrect
The best explanation for the difference in shape between the two drops given in image is - Option D. glycerin is polar and has greater cohesion than hexane.
Polarity is the physical characteristics of liquid that allows them to stick to other substances which is called adhesion. Polar molecules also attracted to itself, and this physical trait called cohesion. Water's most common form in the air, a droplet is formed due to this cohesion.
Hexane is a nonpolar solvent that has less electro negativity charge therefore, they do not have hydrogen bonding and there is less cohesion in the molecules.Glycerin is a polar solvent that allows its molecules to attract itself that is cohesion present and lead to more of droplet shape.Thus, the correct answer is - option D.

what is the range of the pH scale
Answer:
pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

1. What is the most important mutation that led to human life?
Answer:The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.
Explanation:
Adaptive cellular mechanisms are responses to changes in what?
Answer:
Unsourced material may be challenged and removed. In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse environmental changes. The adaptation may be physiologic(al) (normal) or pathologic(al) (abnormal).

which of the following statements describes the role water plays in a rain storm
Answer: D. All of the above.
Explanation:
Shenya Jones, a 34-year-old female, arrives at the office with a swelling and a red pustule on her face. She states the problem started two days ago as a small pimple near her nose. It became irritated then became extremely swollen and painful overnight. This morning there was yellow drainage noted at the site and the swelling has increased. The area of drainage is approximately 1 cm in diameter. The upper lip, side of the face, and nose are all swollen. She rates the pain in her face as a 7 out of 10. The physician thinks the condition may be impetigo or methicillin-resistant Staphylococcus aureus (MRSA), a type of skin infection that is resistant to the common antibiotics used to treat it. A wound culture is obtained.
1. Considering the structures of the skin, what most likely was the cause of the original pimple on this patient's skin?
2. How could Shenya have prevented this skin infection?

why plant cells require sunlight to make organic compounds, according to Gibbs's theory of free energy?
O The photosynthetic reaction releases free energy to the surroundings.
O The photosynthetic reaction's free energy is in equilibrium.
The reactants of photosynthesis have less free energy than the products,
The change in free energy (AG) of the photosynthetic system is less than zero.
Answer:
I'm not sure if this is correct but I think it's C
Answer:
C ( I think)
Explanation:
If a chemical reaction requires an energy input rather than releasing energy, then the ∆G for that reaction will be a positive value. In this case, the products have more free energy than the reactants. Thus, we can think of the reactions’ products as energy-storing molecules. We call these chemical reactions endergonic reactions, and they are non-spontaneous. An endergonic reaction will not take place on its own without adding free energy.

How can the arrangement of atoms help explain how the white phosphorus and red phosphorus can both be pure phosphorus substances?
Answer:Phosphorus is a chemical element with symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate.
Explanation:
Chemical element phosphorus has the atomic number 15 and the letter P in its symbol. Phosphorus, a multivalent nonmetal belonging to the nitrogen group, is generally always found in the form of inorganic phosphate, which is phosphorus in its maximally oxidized state.
What is phosphorus?The mineral phosphorus, which is also available as a supplement, is naturally present in many foods. It serves the body in a multitude of capacities. It is a crucial component of cell membranes, bone, and teeth. It maintains a healthy range of blood pH and aids in the activation of enzymes.
All tissues and cells must have phosphorus for growth, maintenance, and repair as well as for the creation of DNA and RNA, the genetic building blocks. The balance and usage of other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc, depend on phosphorus as well.
Thus, Chemical element phosphorus has the atomic number 15.

if you are at 120X and the field diameter is 8.0 mm what is the field diameter if you go to 30X magnification?
Answer:
32 mm
Explanation:
The field of view is the total area visible through the microscope . The diameter of the field of view can be measured.
There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.
The relationship between field diameter and magnification is:
magnification of A * field diameter of A = magnification of B * field diameter of B
120X * 8 mm = 30X * B
B = 120X / 30X * 8 mm
B = 32 mm = 32000 μm
The field diameter of 30X magnification is 32 mm (32000 μm)

Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
An investigator wishes to use animals in an experiment that involves category B, C, and D activities performed on the same animal. How should the animal be categorized
Answer:
Category D
Explanation:
In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.
