Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.
Answer:
Explanation:
An abiotic factor is a part of an ecosytem, but it is not alive. Some examples include water, rocks, sunlight, and the atmosphere.
On the other hand, a biotic factor is a living part of an ecosystem. Some examples are animals, plants, and fungi.
Let's look at the answer choices.
A creosote plant (choice A) kangaroo rat (choice C) and coyote (choice D) are all living organisms. Therefore, they must be biotic factors.
However, rocky desert soil (choice B) is not living. It's a part of the ecosystem, but since it's not alive it must be <u>abiotic.</u>
The tailbone is an example of a homologous stucture.
The correct answer is option C, that is, the insects could grow resistant to the pesticide in the genetically-modified corn and become immune to regular pesticides.
The genetically modified organisms are usually developed to be more resistant to pesticides or produce pesticides themselves. The GM crops do not have monarch butterflies or honeybees. However, the insects that consume genetically modified crops can, in some of the circumstances, begins to establish a resistance to the protein that usually kills them.
The reason why the RNA has decrease stability compared to
DNA is because the DNA, is lacking a hydroxyl group in which making it more
stable than of the RNA, that is why RNA has decrease stability than the DNA.
