Examine the comparison between a eukaryotic cell and a prokaryotic cell. Which two lettered choices provide a comparison of structures that encode genetic information for the cells? A) A and D B) B and D C) C and D D) None of these choices, as prokaryotic cells do not contain DNA
I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

Identify this functional group
Answer:
Hydroxyl
Explanation:
Hydroxyl groups are simple structures consisting of an oxygen atom with two lone pairs bonded to a hydrogen atom.
A hydroxy or hydroxyl group is a functional group with the chemical formula -OH and composed of one oxygen atom covalently bonded to one hydrogen atom.
Using these given definitions, a hydrogen bond is labeled with one linkage, while a covalent bond is with two links to the Carbon Atom.

The left cerebral hemisphere controls the muscles on the right side of the body and vice versa. Which pathway generalization best explains this phenomenon
Given our understanding of neuroanatomy, we can confirm that the left cerebral hemisphere controls the muscles on the right side of the body and vice versa due to the motor decussate of the cortical spinal pathway.
A decussate in regards to the nervous system is described as when the nerve fibers cross from one side of the central nervous system to the other. The decussate in question corresponds to the cortical spinal motor decussate.
The cortical spinal pathway is the nerve pathway that is in charge of muscular control and therefore is the pathway that is responsible for the phenomenon described in the question.

Explanation:
Acceleration is the speed which you are increasing by per second. Therefore to find acceleration all you need to do is divide the change in velocity (4.5) by the time (2). Your units than become (m/s)/s or m/s^2.

Explanation:
This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others
The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.
In the ecosystem, the living and non-living things interact over time leading to exchange of energy.
A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.
The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).
The energy flow is indicated with an arrow thus,
grass ---> rabbit -----> wolves.
Food chain, therefore includes linear sequence of organisms.
Food web on the other hand illustrates a complex feeding relationship within the ecosystem.
The food web is made up of a prey that can be eaten by more than one predator.
Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

Say that you look at the nuclei of 100 skin cells taken from the same person. About how many of these skin cells would you expect to be in interphase
Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

What is the empirical formula of a compound that contains 4.03 g of hydrogen per mole, 64.14 g of sulfur per mole, and 128.00 g of oxygen per mole?
Answer:
Oct 27, 2015 · CH_4 For this kind of problem, you can assume that the weight of the unknown sample is 100g ( since 75% C + 25% H = 100%). Thus, weight of C = 75g weight of H = 25g Since chemical formulas deal with number of moles rather than weight in grams, you need to convert each element by multiplying it to their respective atomic masses.
Explanation:
The empirical formular i H₂SO₄
The first step is to calculate the compound by the molar mass
Hydrogen, Sulphur, Oxygen
4.03/1 , 64.14/32 , 128/16
4.03 , 2 , 8
Divide by the lowest value
4.03/2 , 2/2 , 8/2
2, 1 , 4
H₂SO₄
Hence the empirical formula is H₂SO₄

True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

what are some drawbacks to using mice in genetic studies?
Answer:
One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.
hope this helps
Explanation:
Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.
Why it's bad to use mice as an experiment:
The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.
The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.
Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.
The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.
