The correct answer is option A. Carrying the genetic code and determining an organism's structure and function are the functions of DNA. It is the hereditary material in almost all other organisms. The information in a DNA is stored as codes that is composed of chemical bases.
Answer:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b: Progeny ratio= 1: 1: 1: 1
c: 1/4
Explanation:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.
Gametes formed by female parent: All gametes with "bn" alleles.
c. The probability that the offspring will have a genotype of Bbnn=
Bb x bb= 1/2 Bb: 1/2 bb
Nn x nn= 1/2 Nn: 1/2 nn
Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.
Answer:
The statement true of all proteins, carbohydrates and fats is that human body is able to synthesize them all.
The statement unique to proteins is that proteins are made up of instructions according to DNA.
Explanation:
Carbohydrates, Proteins and fats are macronutrients and required by body in larger amounts. All these macromolecules are made up of building blocks like proteins are from amino acids, carbohydrates from monosaccharides and fats from triglycerides. Human body can also synthesize these macronutrients. Like proteins can be synthesized by central dogma. Glucose can be synthesized by gluconeogenesis from glycogen and fats can be synthesized from acetyl-CoA and NADPH.
The proteins are made up by a process known as central dogma. The first step of central dogma is replication in which a replicated copy of DNA is produced in a cell. The second step is transcription for the production of messenger RNA from DNA. At last mRNA is used for the production of proteins on ribosomes.
Answer:
B. CO2
Explanation:
Photosynthesis is the process by which plants and algae use energy from the sun to synthesize <em>C02</em>

Answer:
The correct answers are: B) Catalase works best at human body temperature, C) Normal human body temperature is 98.6°F, which equals 37°C.
Explanation:
Catalase is an enzyme found in our bodies that has the important task of <u>breaking down hydrogen peroxide</u>, a molecule that is very toxic. For catalase to work at its optimus speed, it need the body to have a temperature of 37° celsius -98.6°F-, which is what we normally call <em>human body temperature</em>. If the temperature rises or falls below body temperature, catalase will still work but at a much slower rate, until it stops working completely.
Not all enzymes work best at human body temperature, some enzymes reach their optimus state at higher or lower temperatures; but it is important to remember that enzymes are proteins, and proteins denaturalize when the temperature becomes to high, making them lose their shape and function.
