A chart illustrating the hereditary pattern of a family and its generation is called a pedigree chart. It represents the characters and illness of a family.

Pedigree is a chart that illustrates the traits inherited in a family and how it gets passed through generations. Also, it represents dominant and recessive alleles.

The correct option is Option D. All of the above

A blood group is controlled by multiple alleles and is a non- Mendelian pattern of inheritance

The correct answer for the blank is Option A. Multiple alleles

The trait is recessive because neither of the parents is diseased and it must be a heterozygous gene in the parent in this case.

The correct answer is Option B. Recessive

Cellular respiration yields water and carbon dioxide from glucose in the presence of oxygen. While in photosynthesis the water and carbon dioxide along with solar energy forms oxygen and glucose.

The correct answer is Option B. The products of cellular respiration are the reactants of photosynthesis.

This is an autosomal dominant disease caused all the infected individuals produced the infected progenies.

The correct option is Option C. Autosomal dominant

The closer placement produces more gas that is oxygen that is produced during the process of photosynthesis.

The correct answer is Option A. The closer the light source the higher will be the amount of oxygen.

Explanation:

3. A pedigree is a family tree that maps how a trait appears in a family.It maps the inheritance of the trait from generation to generation, and shows scientists features of the trait, for example the pattern of inheritance, whether it is sex linked, and whether it is dominant or recessive

4. There are multiple alleles that cause different blood type phenotypes in humans, but these are all variations of one gene. There are A, B, and O alleles. A and B show codominance, if a person has both of these alleles they will express both as part of the phenotype.

10. The trait is recessive. This can be definitively determined because there are individuals in the youngest generation who have the trait even though neither of their parents have it. This means both parents must be heterozygous for the trait

Respiration question . b. The reactants of photosynthesis are carbon dioxide and water, which, with sunlight, are used to make sugars, which can be used as an energy source for the cell, and oxygen as a by-product. The glucose and oxygen are used in cellular respiration to produce chemical energy, with the release of carbon dioxide and water.

4. The inheritance cannot be sex-linked, because there is an affected male in generation II who must have got his Y chromosome from his affected dad (and therefore his X from his unaffected mother). This is likely autosomal dominant, because all the affected individuals go on to have affected children.

9. The chart shows that the closer the plant is to the light source, the more gas is produced. This gas is oxygen, which is released during photosynthesis. Therefore, the closer the light source, the more chemical energy available to drive photosynthesis and the more photosynthesis that is carried out

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
