For each glucose that enters glycolysis, 10 NADH enter the electron transport chain.
NADH and FADH, which function as electron transporters as they move through the inner membrane region, are involved in the processes of the electron transport chain. Electrons are transferred from NADH to the electron transport chain at complex I, where they transit through the other complexes. In this mechanism, NADH is oxidized to NAD.The four protein complexes of the electron transport chain use this energy to oxidize NADH and FADH2 (ETC). Each of the three previous stages of respiration—glycolysis, the conversion of pyruvate into acetyl-CoA, and the citric acid cycle—contributes two of the ten NADH molecules that enter the electron transport. The citric acid cycle contributes six of the molecules. The citric acid cycle is where the two FADH2 come from.learn more about Electron transport chain here: https://brainly.com/question/18686654

Which of these is least likely to cause speciation? choose the correct answer.
a) sea levels fall, exposing a land bridge.
b) a new highway is built, separating members of a species.
c) some members of the species begin to favor new mating habits.
d) certain members of a species begin to specialize in a different food source.
b) a new highway is built, separating members of a species.
What is speciation?Speciation is the process by which new plant or animal species are developed. When a group within a species separates from other members of its species and evolves its own special traits, this is known as speciation.
What are the causes of speciation?In eukaryotic species, the processes of genetic separation (the division of one gene pool into two or more distinct gene pools) and phenotypic differentiation (the diversification of a population's range of observable physical traits) are both crucial to speciation. There are various theories on how speciation begins, and they diverge mostly in how geographic isolation and the origin of reproductive isolation are accounted for.
What are the types of speciation?Allopatric speciation
Populations that are totally divided (allopatry) by a natural barrier, such as a mountain range, river, or desert, most frequently experience geographic isolation. The two distinct populations have evolved to fit their distinct surroundings, and as a result, they have genetically diverged to the point where they cannot interbreed.
Sympatric speciation
In sympatric speciation, geographic isolation is not present; reproductive isolation takes place within a single population. Reproductive isolation typically occurs when populations are physically separated.

The beetles that died were unable to avoid or detoxify the chemical and were thus killed by nerve poison insecticides.
Chemicals called insecticides are used to kill insects or stop them from acting in an unwanted or destructive way. Their structure and mechanism of operation are used to categorize them.Most insecticides function by interfering with the insect's nervous system. The herbicide prevents neurotransmitters in synapses from transmitting information. Acetylcholine is the name of the substance that the body produces and uses to transmit information through synapses. Muscles can relax because of an enzyme called cholinesterase that binds to acetylcholine.Through the synapses, acetylcholine communicates with the muscles. The cholinesterase is impacted when a pesticide is administered at a deadly dose for a specific body, preventing it from binding with the acetylcholine. The muscles become overstimulated as a result, which will cause paralysis and death.

Liam is dehydrated because he has not drank enough water and has been exercising.
how will his body's endocrine system respond? why?
Antidiuretic hormone (ADH) is released by the hypothalamus through the posterior pituitary gland. The kidneys receive a signal from ADH to extract water from urine, which effectively dilutes the blood plasma.
What is dehydration?A condition that develops when the body loses too much of the fluids it needs to function normally, including water.
How does the endocrine system respond to dehydration?A person who is dehydrated, characterized by a net loss of water, which leaves insufficient water in the tissues and blood. Eventually, blood plasma is used to remove the water that leaves the body as exhaled air, perspiration, or urine. The thirst response, a chain of physiological events, is initiated as the blood gets more concentrated. In the thirst center of the hypothalamus, osmoreceptors are sensory receptors that keep track of the blood's osmolality, or solute content. The hypothalamus sends signals that cause a person to become aware of their thirst if blood osmolality rises above a healthy level. Water consumption is the appropriate response, and it usually is.
A dehydrated person's hypothalamus also releases antidiuretic hormone (ADH) via the posterior pituitary gland. The blood plasma is diluted as a result of ADH telling the kidneys to extract water from urine. A dehydrated person's hypothalamus also tells the salivary glands in the mouth to preserve water through the sympathetic nervous system. The signals cause a decrease in the release of watery, sour substances. This alteration in secretions causes "dry mouth" and a thirst-inducing sensation.

Medial Compartment of the thigh F. Anterior thigh select 1. Posterior tibial artery 2. Femoral artery 3. Radial artery 4. Obturator artery 5. Deep femoral artery 6. Anterior tibial artery
Explanation:
The main artery of the lower limb is the femoral artery. It is a continuation of the external iliac artery (terminal branch of the abdominal aorta). The external iliac becomes the femoral artery when it crosses under the inguinal ligament and enters the femoral triangle.
In the femoral triangle, the profunda femoris artery arises from the posterolateral aspect of the femoral artery. It travels posteriorly and distally, giving off three main branches:
Perforating branches – Consists of three or four arteries that perforate the adductor magnus, contributing to the supply of the muscles in the medial and posterior thigh.
Lateral femoral circumflex artery – Wraps round the anterior, lateral side of the femur, supplying some of the muscles on the lateral aspect of the thigh.
Medial femoral circumflex artery – Wraps round the posterior side of the femur, supplying its neck and head. In a fracture of the femoral neck this artery can easily be damaged, and avascular necrosis of the femur head can occur.
After exiting the femoral triangle, the femoral artery continues down the anterior aspect of the thigh, through a tunnel known as the adductor canal. During its descent, the artery supplies the anterior thigh muscles.
The adductor canal ends at an opening in the adductor magnus, called the adductor hiatus. The femoral artery moves through this opening, and enters the posterior compartment of the thigh, proximal to the knee. The femoral artery is now known as the popliteal artery.

Starch and cellulose are both polymers of glucose. If humans possess enzymes that can break down starch, why can they not use cellulose as a source of glucose as well
Humans cannot use cellulose as a source of glucose because Our digestive systems lack the enzymes necessary to hydrolyze the cellulose's -glycosidic bonds.
Cellulose is a key component of plants' stiff cell walls. A linear polysaccharide polymer with lots of glucose monosaccharide units is cellulose. Because of the beta acetal bond, it differs from starch. A significant disparity in digestibility in humans is caused by this particular variation in acetal linkages. Because they lack the necessary enzymes to dissolve the beta acetal bonds, humans are unable to digest cellulose. The intestinal tracts of creatures including cows, horses, sheep, goats, and termites contain symbiotic bacteria. The enzymes required to breakdown cellulose in the GI tract are present in these symbiotic bacteria. They possess the necessary enzymes for the breakdown or hydrolysis of the cellulose, whereas animals—not even termites—do not.
