Which of the following describes type 2 diabetes
mellitus?
O strongly associated with obesity
O most often diagnosed during childhood
O associated with a tendency to develop ketosis
O sometimes caused by a viral infection
Type 2 diabetes mellitus is strongly associated with obesity and is therefore denoted as option A.
What is Obesity?This is a condition which is characterized by excessive body fat being present in individuals as a result of underlying health conditions such as diabetes etc.
Diabetes on the other hand is a condition in which the blood glucose level is very high as a result of insufficient insulin produced or the body resisting it. This leads to the blood glucose being stored in the body as fat which results in the obesity being experienced by majority of people with this type of condition.

The carbon dating technique would only be best for a Neanderthal bone from 40,000 years ago.
What is carbon dating?
Organisms are known to exchange [tex]^{14} C[/tex] with their environment while they are alive. There are two types of carbon isotopes which are carbon 12 and carbon -14.
The carbon -14 is known to be radioactive. As such, the decay of the carbon - 14 isotope could be used to obtain the age of the sample of the radioactive sample.
Again, it is known that the limit of the accuracy of the carbon-14 system of dating technique lies around 50 000–60 000 years. It then follows that the carbon dating technique would only be best for a Neanderthal bone from 40,000 years ago.

Which best explains enzyme specificity?
O An enzyme is able to react with many different substrates
O An enzyme works best at certain pH
O An enzyme works best at a certain temperature
O An enzyme is only able to react with one substrate
The correct placement of side-chain functional groups that interact with the charged groups of the new substrate is necessary to change an enzyme's selectivity. In order for the functional groups to be positioned correctly, this necessitates sequence alterations that not only add the new functional groups but also modify the structure of the protein backbone. We present a computational design approach for the targeted modification of loops close to the active site to introduce unique enzyme-substrate interactions. The approach can restore native loop lengths and, frequently, native loop conformations, according to benchmark studies on 8 native protein-ligand complexes. Next, we redesign a crucial loop in human guanine deaminase using the technique to ensure that an important side-chain contact is made with the substrate ammelide.

Glyphosate is a chemical used in herbicides to kill plants. Glyphosate works
by stopping the production of amino acids. Which type of organelle must
interact with glyphosate, to prevent the amino acids from joining together
and killing the plants?
The correct answer is shikimate type of organelle must interact with glyphosate, to prevent the amino acids from joining together and killing the plants .
Glyphosate inhibits the enzyme 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase in plants, disrupting the shikimic acid pathway. The resulting decrease in EPSP production reduces aromatic amino acids, which are essential for protein synthesis and plant growth.
Glyphosate is a non-selective herbicide, which means it will kill nearly all plants. It prevents plants from producing certain proteins required for plant growth. Glyphosate inhibits a particular enzyme pathway, the shikimic acid pathway. Plants and some microorganisms require the shikimic acid pathway. Glyphosate is a phosphonic acid formed by the formal oxidative coupling of methylphosphonic acid's methyl group with glycine's amino group.

Which of the following values best represents the amount of energy available for secondary consumers in the food
chain?
(A) 930 kilocalories
(B) 9,300 kilocalories
(C) 93,000 kilocalories
(D) 930,000 kilocalories
Algae in an aquatic food chain convert solar energy into 93,000 kilocalories of plant tissue. 930 kilocalories represents the amount of energy available for secondary consumers in the food chain.
The transfer of 93,000 kilocalories to the secondary consumer is done by the 10% law. The 10% rule states that ''10% of the energy transfer occurs from one trophic level to the following one after it. The remaining energy is lost during energy transfer and respiration. The most energy is found in the first trophic level.
Transfer of 93,000 kilocalories to the primary consumer can be calculated by,
Energy available for Primary Consumer= [tex]\frac{93,000 kcal x 10}{100}[/tex] = 93,00 kcal
Transfer of 93,00 kilocalories to the secondary consumer can be calculated by,

HELP ME ASAP 18. Why do animals in cold environments need a lot of lipids in their cells? ok
Answer:
As temperature increases, so does phospholipid bilayer fluidity. At lower temperatures, phospholipids in the bilayer do not have as much kinetic energy and they cluster together more closely, increasing intermolecular interactions and decreasing membrane fluidity.
Explanation:
When temperature decreases, the composition of membrane lipids (phospholipid fatty acids) is expected to become more unsaturated to be able to maintain homeoviscosity.

Answer:
d. 4; 2
Explanation:
To reduce one molecule of O2, 4 electrons must be passed through the electron transport chain and 2 molecules of NADH are oxidized. So the correct option is D.
What is the electron transport chain?
A chain of compounds known as the "electron transport chain" uses the electrons from an electron carrier to create a chemical gradient. It could function as the fuel for oxidative phosphorylation. The molecules that make up the chain include peptides, proteins, enzymes, and other substances.
Oxidative phosphorylation is a highly effective way for producing large amounts of ATP. A crucial component of the metabolic process is ATP. ATP is produced as a result of the transport of electrons from the electron acceptor to the electron donor. In the electron transport chain, it is one of the crucial stages. The most ATP is created in this phase of cellular respiration compared to any other phase.
Therefore the correct option is D.

Describe the two types of climate hypothesis that involve interactions between CO2 and weathering.
The two types of climate hypotheses that involve interactions between CO2 and weathering are as follows:
Over the years the volcanoes and mid-ocean ridges have been constantly casting carbon dioxide into the Earth's atmosphere. Despite this, the planet has stayed largely habitable. The primary cause for this is that carbon dioxide is also constantly drawn down from the atmosphere via chemical weathering reactions with the rocks at the surface. Weathering is the procedure by which carbon dioxide present in the atmosphere breaks down rocks and then gets entrapped in a deposition. It is an important part of Earth's carbon cycle, shuffling carbon dioxide between the atmospheric regions, and controlling global temperatures. By sealing carbon dioxide out in deposits, weathering extracts it from the atmosphere over extended timescales, decreasing the greenhouse effect and decreasing Earth's temperatures.To learn more about climate here

Carbonic anhydrase is a protein present in red blood cells. It catalyzes a reaction to convert carbon dioxide into carbonic acid and bicarbonate ions so that CO2 waste may be more easily removed from the body.
What role does this protein play in the body?
Carbon dioxide is converted to carbonic acid and bicarbonate ions with the help of the enzyme carbonic anhydrase found in red blood cells. The same enzyme aids in converting the bicarbonate ions back to carbon dioxide when red blood cells go to the lungs, where they are exhaled.
What is the action of carbonic anhydrase?In humans, the primary function of carbonic anhydrase is to catalyze the transformation of carbon dioxide into carbonic acid and back again.
