<span>Proteins are different based on number and type of ____________ contained in their polypeptide chain(s)
</span>Amino acids
Answer:
The correct answer is c reducing agent.
Explanation:
Photosynthesis consist of both light reaction and dark reaction.The light reaction result in the formation of ATP and NADPH.The so formed ATP and NADPH are used in dark reaction to fix CO2 resulting in the production of glucose.The principle of ATP to provide energy to carry out the CO2 fixation process of dark reaction.
NADPH act as a reducing agent that reduces the phosphoglyceric acid(PGA) into phosphoglyceraldehyde(PGALD).
Answer:
B
Explanation:
Both traits on the left are dominant meaning the offspring would take on that trait no matter what.
Answer:
The genotypes thatwould be considered pure breeds are BB and bb
Explanation:
The genotype of an organism refers to an organism's complete set of genetic material or genes.
Genes are units of DNA that carries information for a particular physical or functional trait or character in an organism. Some genes act as instructions to make proteins while some genes do not code for proteins. The proteins made by a gene expresses the traits and characters of that organisms. Genes for a particular trait may have one or more variants known as alleles.
In Gregor Mendel's research using pea plants, flower colour in a pea plant had two different alleles; one for red flower colour and one for white flower colour. If a plant had the same allele for flower colour, the plant was considered a pure breed.
For example, given B was the allele for red flower colour and b was the allele for white flower colour, a plant having the two alleles for white flower colour bb, is a pure breed. Similarly, a plant having the two alleles for red flower colour, BB is a true breed.
When an external stimulus crosses the threshold, a muscle fibre will respond.
<h3>The level of the threshold</h3>
- For the identification of the electrical activity carried out by the active muscles, the threshold level is a crucial consideration.
- A portion of the electrical activity carried out by the target muscles may be excluded if the chosen threshold level is higher than the overall activity.
<h3>What is the stimulus threshold for muscle contraction?</h3>
- A certain stimulus magnitude is necessary for muscle contraction.
- The threshold stimulus is the smallest amount of force needed for a stimulus to cause a muscle to contract in response.
- If the stimulus intensity is less than this threshold value, there is no response.
