Answer:
The correct answer is - to protect the cells of these secretory glands from pepsin.
Explanation:
Pepsinogen is an inactive form of enzyme pepsin that is released by specific cells called chief cells within the gastric lining Releasing the inactive form of pepsin in preventing the auto-digestion of protective proteins and the cells of these secretory glands in the lining of the digestive tract.
Pepsinogen is activated by acidic pH to pepsin of the stomach lumen and the cell lining of the stomach is protected by mucus lining.
Which materials are moved by runoff?
Answer: Gravity causes the water to flow downhill. As the runoff flows, it may pick up loose material. These materials may include bits of soil and sand. It is carried off by this running water across the surface of the land.

I need someone who studies biology and genetics.
Is a pig crossed with a chimp possible, I just read an article about this and the person who had the idea was someone with the last name MCkarther PH.D. it made the news.
Answer:
The cross between two different species is called hybridization. The truth is that, for hybridization to occur, the species in question must have a certain kinship with each other, that is, they must belong to the same family of animals. An example is the cross between tigers and lions, pigs and wild boars, donkeys and donkeys, etc. Now, if there is no such familiarity between species, the truth is that hybridization will not be possible, which is the case of pigs and chimpanzees with each other.

why cant food chain be indefinitely long
Answer:
Because:
Explanation:
Some energy is lost gradually in several ways at each trophic level:
Energy is lost through respiration, generating heat at each trophic level.
Energy is lost through waste (waste through excretion, feces, leftovers, etc. or energy lost through shedding of leaves in plants, shedding, molting of animals, ..) at each trophic level.
The higher the food chain (or trophic level), the less energy accumulates and to a certain extent there is no longer enough to maintain a link (of a trophic level). When a link (actually a species or group of card fish of a species) has too few individuals (smaller than the minimum size of the population) will not exist.

Among native Americans, two types of earwax (cerumen) are seen, dry and sticky. A geneticist studied the inheritance of this trait by observing the types of offspring produced by different kinds of matings. He observed the following numbers:
Parents Number of mating pairs Offspring
Sticky Dry
Sticky × sticky 10 32 6
Sticky × dry 8 21 9
Dry × dry 12 0 42
a. How is earwax type inherited?
b. Why are there no 3:1 or 1:1 ratios in the data shown in the chart?
Answer and Explanation:

The endocrine system consists of ________
A)
association areas.
B)
neural networks.
C)
interneurons.
D)
glands.
Answer: The endocrine system consists of Glands.
The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.a) A plant with the genotype DR/dr (representing the allele combination on each chromosome) produces gametes. List the genotypes of the gametes that can be produced and label each gamete as parental or recombinant.

2. How can a genetic mutation be beneficial to an organism?
3. What are some other evidences of evolution discussed in this unit?
Answer:1.Selection of the dark-colored moths over light-colored moths after industrial evolution is an example of directional selection while selection of alpha males and “sneaking” males over intermediate males in a lobster population is an example of disruptive selection.
2.organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur.

the letters A, T, C, and G get highlighted in the people’s names. DESCRIBE the significance of these letters.
Answer:
Explanation:
If you are talking abou the movie GATTACA, then the reason is that A, T, G, and C are DNA coding letters so it would sort of make sense to highlight those to complement or enhance the movie's meaning (its also part of the movie's name)
