Answer:
AA
Explanation:
A true breeding organism for a particular trait is an organism that would produce progeny with the same trait whe self fertilized.
Hence, since axial flower is represented by the allele A, a true breeding flowering plant will have the genotype AA.
Axial flower (A) is dominant over terminal flower (a).
True-breeding axial flowering plant will have the genotype AA.
True breeding terminal flowering plant will have the genotype aa.
AA is crossed with aa.
AA x aa
offspring: Aa, Aa, Aa and Aa.
All the offspring will exhibit axial flowering.
<span>A. to produce ATP and NADPH for the light-independent reactions
Remember, the purpose of photosynthesis is to provide energy for the plant to perform other chemical reactions during the process of growing. So now, let's take a look at the possible answers and see why they do or do not make sense.
A. to produce ATP and NADPH for the light-independent reactions
* Both of these are nice high energy compounds produced directly by photosynthesis. Unless we see a better option later, this looks like a good choice.
B. to convert carbon dioxide into water
* Does this provide energy to the plant? No it does not. So this is a bad choice.
C. to release oxygen into the atmosphere
* This is a happy side effect of the process for us mammals, but it's not the main purpose of photosynthesis and in fact doesn't provide energy to the plant. So wrong choice.
D. to break down glucose into pyruvic acid
* This does produce energy. But doesn't require light. So it has nothing to do with photosynthesis. Wrong choice.</span>
Answer:
The primary function of mucus in the stomach is <u>protect the stomach cells from gastric juices (e.g., HCl).</u>
Explanation:
The stomach is an important organ in the process of digestion, it performs a variety of functions that include the storage and exposure of food to the acid it secretes, in addition to providing a barrier that prevents the passage of microorganisms to the intestine. The gastric mucosa protects the stomach from digestion caused by acid gastric juices in which the superficial cells of the mucosa would produce a mucous layer, which would leave the stomach completely unprotected. The stomach creates gastric acids to break down food. These acids, also called gastric juices, are very strong acids found in the stomach. Its function is to promote the digestion of proteins that come from the products we eat. The components of gastric juices are produced by the gastric glands found in small cavities of the gastric mucosa. The gastric glands are elongated and consist of several types of cells: superficial cells, main cells and parietal cells. Superficial cells produce mucus that protects the stomach from attack by digestive acids and enzymes.
