Saccharomyces cerevisiae (a yeast species) mutants are available that grow on pyruvate or ethanol, but not sugars or glycerol.
mezya [45]

Answer:

The enzyme is the pyruvate kinase

Explanation:

The designated enzyme can only grow in pyruvate or in ethanol. They are said to be in anaerobic conditions. If the end product of glycolysis is pyruvate and the enzyme that transforms phosphoenol pyruvate into pyruvate is called pyruvate kinase. In a reaction under anaerobic conditions, the pyruvate is transformed into ethanol. So if the pyruvate kinase enzyme is mutated, pyruvate cannot be transformed into ethanol and Saccharomyces cerevisiae could not survive in that medium.

The act of breathing raises the blood oxygen level, lowers the blood carbon dioxide concentration, and raises the blood pH. Acco
tino4ka555 [31]

Answer:

A rise in blood carbon dioxide concentration.

Explanation:

The feedback regulation may be defined as the process in which the end product of the metabolic pathway regulates the homeostasis of the body. Two main types of feedback are positive feedback and negative feedback.

The negative feedback mechanism occurs when the end product of the reaction is responsible for the shutdown of the metabolic pathway and decreases its concentration. The breathing is controlled by the negative feedback mechanisms, the increase in carbon dioxide concentration acts as the negative sensor as this sensor is mainly responsible for the increase in amount of oxygen level and maintain homeostasis of the body.

Thus, the correct answer is option (c).

Explain two effects that the study of genes could have on the future.
adoni [48]
1) determine the probability of individuals inheriting a disease
2) In the future, new genetic mutations will arise, and knowing to understand genetics would be important in helping analyze the problem/mutation in genetic recombination.
3) Genetics allows us to link diseases to one another (pedigrees) by analyzing if they are recessive, dominant, and/or autosomal, this allows us, as scientists to be able to identify and classify future diseases, and to determine their inheritance pattern, in the future.

B) Describe your duties as a plant scientist who is involved in creating a new strain of a plant using genetic engineering.
salantis [7]

3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.

<h3>How is lineage improvement done?</h3>

The answer is to obtain populations with genetic variability. This can be achieved through hybridization or crossbreeding. Hybridization is the fusion of genetically different gametes, which results in hybrid individuals heterozygous for one or more loci.

With this information, we can conclude that 3 specific tasks you must do while working with Professor Ingo Potrykus on this specific project is plant hybridization, growth recognition and quality of the products obtained.
