What is the function of multiple alleles?Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but are codominant. This means that the following genotypes will give rise to the phenotypes as follows:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, if a mother with Type O (ii) blood and a father with type AB (iAiB) blood are crossed, the following offsprings will be likely produced:
iAi, iAi, iBi, iBi
iAi - type A
iBi - type B
Hence, the possible phenotypes of the children will be type A and type B blood.
Therefore, A mother has type A blood but is a carrier for O. A father has AB blood.

In some cats , the gene for tail length shows incomplete dominance . Cats can have no tails ( NN ) , long tails ( LL ) , or short tails ( NL ) . Cross a short tail cat and a cat with no tail . Show genotypic and phenotypic percentages of the generation .
The phenotypic percentages would be: No tail: 50%, Short tail: 50%, Long tail: 0%.
What is phenotype?The term "phenotype" describes a person's observable characteristics, such as height, eye color, and blood type.
Both a person's genomic make-up (genotype) and environmental circumstances affect their phenotype.
We know that the offspring would receive one allele for tail length from each parent based on the incomplete dominance principle. The genotypes of the progeny would be:
NN: This genotype would be present in all of the offspring, resulting in no tail phenotype.NL: This genotype would result in a short tail phenotype in 50% of the progeny.LL: A long tail phenotype would emerge from this genotype, which would be present in 0% of the progeny.Thus, this can be the genotypic and phenotypic percentages of the generation.

All of the following could be products of hydrolysis except: A steroid, option B.
What occurs during hydrolysis?Hydrolysis is a chemical reaction in which water is used to break apart a larger molecule into two smaller molecules. The water molecule is split into a hydrogen ion (H+) and a hydroxide ion (OH-), and these ions participate in the reaction by attacking the bonds in the larger molecule.
Steroids are not typically broken down by hydrolysis, as they do not contain any hydrolysable bonds. A nucleotide, glucose, a disaccharide, and an amino acid can all be products of hydrolysis reactions, depending on the starting molecule and the type of hydrolysis reaction being performed.

Explanation:
. In a salt marsh in Agusan, the quantity of solar radiation reaching the ground during the summer is 7,000,000cal/m2/day. The gross productivity of the producers in the salt marsh (mostly microscopic algae) is 0.0040 g/cm2/day. The average rate of respiration (the respiration requirement) is 35% of the gross primary productivity. Ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories.
The algae in the salt marsh are very efficient in their use of the solar radiation they receive.
What is solar radiation?Solar radiation is the energy emitted by the sun in the form of electromagnetic waves. These waves consist of visible light, infrared radiation, and ultraviolet radiation. Solar radiation is important for life on Earth as it provides the energy for photosynthesis and drives the water cycle.
The amount of solar radiation reaching the ground in a salt marsh in Agusan during the summer is 7,000,000cal/m2/day. This energy is used by the producers (microscopic algae) to photosynthesize and produce organic matter. The gross primary productivity (GPP) of the producers in the salt marsh is 0.0040 g/cm2/day. This means that the algae are able to produce 0.0040 grams of organic matter per square centimetre of salt marsh every day.
The respiration requirement for the algae is 35% of the GPP. This means that in order for the algae to survive, they must use 35% of the GPP for respiration. This leaves 65% of the GPP to be used for growth and other metabolic needs.
Finally, ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. This means that 1 gram of algae in the salt marsh contains enough energy to provide 2,920 calories. This indicates that the algae in the salt marsh are very efficient in their use of the solar radiation they receive.

What is the pathway of blood in the cardiovascular system
Answer: Through the tricuspid valve, the heart moves oxygen-poor blood from the right atrium to the right ventricle. The blood is subsequently pumped by the right ventricle down the pulmonary artery to the lungs, where it enters the respiration process to absorb oxygen and expel carbon dioxide. The oxygen-rich blood then travels through the pulmonary veins back to the left atrium of the heart. Through the mitral valve, the left atrium delivers blood that is oxygenated to the left ventricle. The aorta, which divides into smaller arteries that carry blood to numerous organs and tissues, is how the left ventricle subsequently pumps the oxygen-rich blood to the rest of the body.
