Fatty acid metabolism disorder is an autosomal recessive disorder. Two unaffected parents have 6 children - all of whom are unaf
Nadusha1986 [10]

Answer:

There are only 2 possible genotypes for the mother, FF and Ff.

Explanation:

Because it is an autosomal inheritance, this case F will be the dominant allele and f the recessive allele, where f produces Fatty acid metabolism disorder. If the mother does not possess the disorder, she must possess at least one dominant allele for that specific gene. However, for the other allele, we cannot assure that it is dominant, since it can be recessive and not express itself either in her or in the offspring, because of the father we also only know his dominant allele.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
AlekseyPX

Answer:

Photosynthetic process

Explanation:

Cellulose, a tough, fibrous and water-insoluble polysaccharide in the cell walls of plants. It is the most abundant organic macromolecule on Earth and also the main component of a plants structure, conferring rigidity on the plants' cells.

Cellulose chains are arranged in microfibrils or bundles of polysaccharides arranged in fibrils which in turn make up the plant cell wall.

All plants are made up of polysaccharides, a very large sugar molecule made of hundreds or thousands of single sugar units (monosaccharide). Cellulose is composed of a long chain of at least 500 glucose molecules joined together by B-1,4- linkages.

Green plants create this simple sugar molecules (glucose) on their own through the process of photosynthesis. Photosynthesis is the chemical combination or fixation of C02 and water by the utilization of energy from the absorption of visible light. This glucose produced is a building carbohydrate that combines with other sugars to form the plant structure (as they make up part of cellulose) and store energy.
