Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.
A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone. It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide. The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid. Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.learn more about Gastric inhibitory peptide here: https://brainly.com/question/13048001

In an energy pyramid, the amount of energy at the producer level is 475,650 kilocalories. the pyramid has four trophic levels, including the producer level. assuming that 10% of the energy is retained at every level, how much energy is available for the second-level consumers? the energy available for the second-level consumers is kilocalories.
The energy available for the second-level consumers is 4756.5 kilocalories.
A trophic level is a position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.
The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.
Calculation:
Producers (475650 kilocalories) —> Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).
So, the energy available for second-level consumers is 4756.5 kilocalories.

A mutation occurred in a population of wombo birds. Birds with the mutation are able to eat mangoes but those without the mutation
cannot. Birds with the mutation no longer fly north during winter and stay to feed on mangoes. What is likely to happen over time?
OA they will evolve into a new species that can't breed with the other wombo birds
OB. the other wombo birds will evolve and become mango eaters too
OC. a new species of mangoes will evolve and live along the wombo birds migration route
OD. they will eat all the mangoes and start migrating again
A mutation occurred in a population of wombo birds, and birds with the mutation are able to eat mangoes, but those without the mutation cannot. This is due to the fact that the other wombo birds will evolve and become mango eaters too, which is option B. So option B is the correct answer.
Since birds with the mutation can eat mangoes, and mangoes appear to be a valuable food resource, natural selection will likely favor the birds with the mutation. As a result, over generations, more and more birds in the population will carry the mutation, and eventually, the entire population may evolve to become mango eaters. This process may take time, and the rate of evolution will depend on factors such as the size of the population, the rate of mutation, and the availability of mangoes as a food source.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
The use of artificial fertilizer has helped the tomato plant to grow faster and taller.
Natural fertilizers such as plant and animal wastes are considered eco-friendly as they are not harmful to the environment. They add nutrients to the soil in a natural way and do not degrade the soil. But, their impact is slow and cannot fulfil all the lacking nutrients. On the other hand, artificial fertilisers are harmful to the environment as they degrade the soilStill, the farmers prefer artificial fertilizers over natural fertilizers. This is because they help the plant to grow faster and taller by fulfilling the requirement of all lacking nutrients.Thus, tomato plants are grown faster and taller due to the use of artificial fertilizers. Artificial fertilizers have a greater impact than natural fertilizers and provide the soil with the required nutrients.

Mutation resulting from changes in a single gene is called Gene mutation.
A gene variation is an alteration to a gene's DNA sequence that takes place throughout time. Gene variation is regarded to be a more accurate word for this sort of genetic change than gene mutation since changes in DNA do not necessarily result in illness.Gene variations can be acquired from one's parents or develop naturally over time.Inheritable variations are present in almost all of a person's cells throughout their lifetime and are transferred from parent to kid.Non-inherited variations appear at some point in a person's life and are found in just a subset of the body's cells, not all of them. Non-inherited variations are sometimes referred to as somatic variants since they generally arise in somatic cells.So we can conclude that a gene variation is a change in a gene's DNA sequence that occurs over time; it is thought to be a more appropriate term for this type of genetic change than gene mutation because DNA variations do not always cause disease, it also resulting from changes in a single gene.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.
The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.
Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

The P50 for myoglobin is 2.8 torr. At what oxygen concentration will myoglobin be 75% saturated with oxygen
At 8.4 torr myoglobin will be 75% saturated with oxygen.
Calculation :
P50 is the partial pressure of the system. To achieve 50% saturation of oxygen to bind to myoglobin, the partial pressure needed is P50
P50 =2.8 torr
so, Mb+ O2 = MbO2
K= [Mb] [O2]/[MbO2]......................(1)
Yo2 ( fractional saturation of myoglobin )
Yo2=[MbO2]/[Mb]+[MbO2]..........................(2)
From equations (1) and (2)
We get Yo2= [O2]/K+[O2]= Po2 /K+ Po2
i)Yo2= 50% =2.8/K+2.8
0.5= 2.8/k +2.8
So, K= 2.8

Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.
The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex. It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex. The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.learn more about QRS complex here: https://brainly.com/question/10842164
