In your post, discuss ONE Neanderthal or Denisovan gene that is currently found within our species. Tell us about the gene and its function. Explain what it does for us. (Make sure you give a citation.) Explain in your own words any possible advantages that your Neanderthal or Denisovan gene might have. Make sure you give in informed opinion that is grounded in your research. Caution: Make sure that your chosen genetic variant is not simply a result of common ancestry. For example: FOXP2 is a gene that Neanderthals and Sapiens share because of common ancestry. Verify that the genetic variant that you are looking at is actually derived from Neanderthals, Denisovans or another species. You will have to respond to two other student posts. Make sure you cite your work.
Answer:
It has been shown that many microRNAs (miRNAs) were differentially expressed in Neanderthal and Denisovan genomes.
Explanation:
MicroRNAs (miRNAs) genes encode for RNA regulatory sequences capable of modulating gene expression patterns, thereby they play critical roles in evolution and development. It has been proposed that these miRNAs might control the expression of TRAPPC9, GRID1, PRDM16, NAV2, SorCS2, CAMTA1, and ASIC genes, which are involved in neurocognitive developmental functions.

Which of the following statements about oxidative phosphorylation by ATP synthase is FALSE? A) The electrochemical gradient across the inner mitochondrial membrane generated by electron flow is used to synthesize ATP. B) Uncouplers dissipate the electrochemical gradient but electron transport continues without ATP production. C) Inhibitors disrupt electron flow as well as ATP synthesis. D) A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP. E) ATP synthesis occurs via simultaneous conformational changes in protein subunits containing catalytic sites.
Answer
D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP
Explanation:
Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.
Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.
What are the characteristics of reptiles?Reptiles, as most commonly defined are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
Moreover, the major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.
Therefore, the name "reptile" comes from Latin and means "one who creeps". All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs. They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts.

How would you describe the movement of the sun over 30 minutes?
Answer:
The Earth rotates from the west to east. The Sun does not rotate around the Earth, in Thirty minutes. the sun would appear to be in a different part of the sky, and that is because of the Earth's rotation.
Explanation:
Answer:
The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates. The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.

Which statement regarding lung cancer is correct?
A. Individuals with emphysema are not at risk for lung cancer.
B. Lung cancers are not aggressive.
C. More Americans die from lung cancer than any other form of cancer.
D. Only smokers will develop lung cancer.
Answer:
The correct answer is: C. More Americans die from lung cancer than any other form of cancer.
Explanation:
Lung cancer is one of the most aggressive cancers in the world, and is also the cancer that kills the most people in America every year (it is estimated that almost 140,000 Americans die from this cancer every year).
Emphysema is a chronic pulmonary disease that occurs when the air sacs in the lungs, called alveoli, enlarge and get damaged. This condition is mostly caused by smoking, and makes up a very significant risk factor for lung cancer.
Even when smoking makes up a huge risk factor for developing this and other types of cancer, non-smokers can develop lung cancer as well.
Answer: A is wrong, emphysema is not a risk factor for lung cancer. Lung cancer is primarily due to exposure to tobacco smoke and carcinogens in the smoke. Emphysema is due to loss of alveolar surface areas due to destruction of alveolar surfaces.The results is loss enough surface area for oxygen and C02 exchange in the lungs.
Generally D is wrong lung cancer is not limited to smokers only, smoking just increases it risk. Passive smokers can also develop cancer.But 45-50 of lung cancers is due to smoking. Beneze inhale from rubber industries,and asbestos industries are other places where Lung cancer can be developed after exposure.
A type of lung cancer can be agressive.(SCLC) While others can be slow.
C is correct.
Thus A is Odd

The use of arsenate instead of phosphate by glyceraldehyde 3‑phosphate dehydrogenase produces 1‑arseno‑3‑phosphoglycerate. Assume that the presence of arsenate only affects the glycolysis step catalyzed by glyceraldehyde 3‑phosphate dehydrogenase and that 1‑arseno‑3‑phosphoglycerate spontaneously hydrolyzes to form 3‑phosphoglycerate.
How many ATP molecules would a single round of glycolysis consume and produce in this scenario?
Answer:
ATP consumed = 2 molecules
ATP produced = 2 molecules.
Explanation:
Arsenate does not produce 1,3-bisphosphoglycerate, so it can be deduced that at least two ATP molecules are produced through normal glycolysis, remembering that phosphoglycerate kinase allows the reaction between 1,3-bisphosphoglycerate transforming it into 3 -phosphoglycerate and generating two ATP, phosphoglycerate kinase catalyzes this reaction and gives 2 ATP.

OC. The oxygen concentration decreases quickly in the nose and mouth, and then remains constant as it passes through other organs of
the respiratory system,
CD. The oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system,
Answer:
the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system
Explanation:
The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.
The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air
15. Knowing that the genetic code is almost universal, a scientist uses molecular biological methods to insert the human B-globin gene into bacterial cells, hoping the cells will express it and synthesize functional B-globin protein. Instead, the protein produced is non-functional and is found to contain many fewer amino acids than does B-globin made by a eukaryotic cell. Explain why.
Answer:
The genetic information of living organisms is sequenced in DNA, which allows inheritable factors to be transmitted with each replication process. Proteins play a very important role by intervening in their metabolism during the translation and transcription of information. .
eukaryotic and prokaryotic organisms have different evolutionary sequelae that are reflected in the mechanisms they use for DNA translation, such as in the initial stages, lengthening and termination of sequencing, these differences are imparted by the order of the genes, the ribosome and its structural form and the promoter sequences.
In this way we can conclude that although the eukaryotic genes enter into a bacterium, the type of information that they take may arrive incomplete and this may generate subsequent defects for their operation, but there may be processes that guarantee a better transfer of information with the use of genetic engineering and enzyme management to introduce different bacterial genetic expressions with eukaryotic genes.
Eukaryotic cells like humans and prokaryotic cells like bacteria vary in central dogma methods.
The generative data of an organism is stored in the sequenced DNA that gets transferred during the process of replication.
The DNA transcription and translation process in prokaryotes and eukaryotes differ like the steps concerned in the beginning and the termination of the arrays are defined by various sets of genes in both types of organisms.
The promoter, ribosomes and the structural genes make both the organism distinct from each other.
So, when the eukaryotic gene intrudes bacteria may lack some data that can get misinterpreted and the resulted proteins or amino acids will differ.

Determine whether each characteristic describes a nonvascular plant or a vascular plant.
are small when fully grown
are always seedless
can be large when fully grown
normally live in moist environments
may have seeds
can live farther from water
Answer:
Vascular plants:
Can be large when fully grown.
May have seeds.
Can live farther from water.
Nonvascular plants:
Are small when fully grown.
Are always seedless.
Normally live in moist environments.
Explanation:
Plants can be classified regarding their flowering and their vasculature. When taking vasculature into consideration, they can be classified as Vascular Plants or Nonvascular plants.
Vascular plants have separate tubular tissues that are used to transport food and water, while nonvascular plants do not have these tissues. For this reason, nonvascular plants have a much harder time controlling the water inside them, and that's why they need to live in humid environments in order to survive. Vascular plants, on the other hand, can live in places farther from water.
Since they do not have vasculature, nonvascular plants are short in length, which makes it easier to survive considering the lack of tubular structures made for transport that vascular plants have.
Nonvascular plants do not have a vasculature, which means they do not have roots, stems, leaves nor seeds.
