How is it possible to have thousands of different proteins when there are only 20 different amino acids

Answers

Answer 1
Answer: The 21 amino acids can be arranged in many different ways. It is possible with just this small number of amino acids to create thousands of different types of proteins. Think of amino acids like they were little connecting blocks, such as legos. You have 21 of them before you. How many different ways can you arrange them? The formation of protein is similar.

Which factor is not used to define biomes? a. plant structures b. leaf type c. historical similarities d. climate

Answers

Historical similarities are not a factor that defines biomes becausethey are identified with particular patterns of ecological succession tomaintain the state of equilibrium of the local ecosystem that has manybiotopes. Biomes are not defined by genetic or historical similaritiesand are different from ecozonas.

Assume that the growing polypeptide chain of amino acids being produced represents an enzyme humans use to help digest starch. The original blueprint for the production of this enzyme can be found, most specifically, in the___________. A). salivary glands.
B). nuclei of gland cells..
C). ribosomes of gland cells..
D). saliva of the human mouth.

Answers

Answer:

The correct answer would be B) nuclei of gland cells.

Starch is a polysaccharide which is digested with the help of salivary amylase and pancreatic amylase in humans.

Enzymes are protein in nature and thus they must be translated from a particular gene. Genes are made up of DNA, nucleotide sequence of which is used as the blueprint for the synthesis of any protein.

This gene would be expressed in the cells of the salivary gland and pancreatic gland.

Thus, the blueprint of this enzyme can be found in the nuclei of gland cells.

I believe it's B. Nuclei of Gland Cells.

In both American cotton (Gossypium hirsutum) and Egyptian cotton (G. barbadense) petal spot is a dominant character over no petal spot. When the cross is made within the species, the F2 progeny segregates in a 3:1 ratio with petal spot character in 75% of the population. However, no clear cut ratio is obtained in respect of the same flower character, when the cross is made reciprocally between the above two species. What is the explanation of this fact?

Answers

 

I would say 4 because genetic drift could cause this if the population is small
