11. Punnett squares can also be used to predict genotypes of the parents. A guinea pig with short hair is crossed
emmainna [20.7K]

Answer:

Ss × ss

Explanation:

This question involves a single gene coding for hair length in guinea pigs. The alleles for short hair (S) is dominant over that of long hair (s).

According to this question, a guinea pig with short hair (S_) is crossed to one that has long hair (ss) to produce offsprings that have 44 short hair and 46 long hair. This number of offsprings produced indicate a ratio of 1:1, which can only be produced if the short haired guinea pig is heterozygous i.e. Ss.

Therefore, the genotype of the parents are Ss (short hair) and ss (long hair) i.e. Ss × ss. This combination will produce offsprings with the following proportion: Ss (1) : ss (1).

Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?
daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

                monomer/glucose     glycosidic bond    branching

1.starch              α glucose          1-4 and 1-6               branch and unbranced

  amylose                                       1-4                          unbranched

  amylopectin                               1-4 and 1-6              branched

2. dextran          α glucose          1-6                           branched

3. cellulose        β glucose           1-4                          unbranched, linear        

4. glycogen       α glucose           1-4 and 1-6              branched (shorter

                                                                                     branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.

The framework of the spleen is created by a network of reticular fibers made by reticular cells. The framework of the spleen is
Reika [66]

Answer: True.

Spleen framework is created by reticular fibres from reticular cells.

Explanation:

Spleen is an organ found mostly in vertebrates. It develop from mesenchymal cells within the dorsal of mesogastrium near the greater curvature stomach. The mesencymal cells then divide and differentied to form framework of connective tissues of spleen. The framework of spleen is created by reticular fibres of the reticular cells. Reticular fibres are fibres in the connective tissue that is composed of type iii collagen secreted by reticular cells. Spleen function in filtering of blood. It plays a major role in red blood cells and immune system.
