Step 3.

Which statement most correctly describes the role of a connecting protein

Tcecarenko [31]

I remember the secondary structure by visualizing it. Understand that primary structure is just the order of the amino acids. The tertiary structure is the 3dimensional configuration of the whole protein molecule with multiple interactions guiding its fold (disulfide bonds, ionic interactions, hydrogen bonds, van der walls). Secondary structure is a step towards the conformation of the protein where it is made up of either alpha-helices or beta-pleated sheets. The alpha helices look like a spiraling staircase while the beta-pleated sheets look like a repetition of long loops. These two structures hold itself by hydrogen bonds.

Ash trees are being removed when they show signs of the ash borer, a parasite that affects the trees and kills them off. What be

guajiro [1.7K]

The ash trees are being cut when the show signs of infestation of the ash borer. Ash borer in particular the Emerald Ash Borer (EAB) is a tiny bug but can really do a great damage to the tree. When the tree is infested with the ash borer, they lay their eggs in the bark of tree, when the eggs hatch the lavas would start eating on the inner tissues of the tree blocking the flow of nutrients and water in the tree that causes the tree’s to death. If the tree is infested they cut it down, burn and bury the wood to stop the spread of infestation. Ash trees are valued for its strength and elasticity that is often used to make baseball bats, bows, tool handles and other products that needs durable wood.

What is the probability that each of the following pairs of parents will produce the given offspring: 1. AABbCc x aabbcc à AaBbC

ICE Princess25 [194]

Answer:

1) AaBbCc, 50% - 2) AAbbCC, 3,125% - 3) AaBbCc is 12,5%.

Explanation:

1º cross.

Parental) AABbCC x aabbcc

Gametes) ABC AbC ABC AbC ABC AbC ABC AbC

abc abc abc abc abc abc abc abc

Punnet Square) Only filled with the progeny genotype AaBbCc.

ABC AbC ABC AbC ABC AbC ABC AbC

abc AaBbCc --- AaBbCc --- AaBbCc --- AaBbCc ---

F1 Genotype) 32/64 AaBbCc

32/64 AabbCc (shown as the symbol "---" in the

punnet square)

The probability of producing offspring with genotype AaBbCc is 50%.

Describe one way in which ribosomes interact with organelles. How would having a larger number of ribosomes benefit a cell? In y

tino4ka555 [31]

Answer:

Ribosomes are the machinery of protein synthesis in the cell. They are associated with different organelle of the cell. They are also found free-floating in the cytoplasm of the cell.

The organelle which ribosomes interact are plasma membrane in prokaryotes and endoplasmic reticulum(ER) in eukaryotic cell. Ribosomes are present on the surface of the ER and helps in protein synthesis in the ER. In prokaryotes, there is no ER so it is associated with plasma membrane and perform protein synthesis.

The specialized function of ribosome is to perform protein synthesis and these proteins are necessary for cell because protein are important to make enzymes that regulate the metabolism of the cell. So if protein synthesis stops cell will not able to perform important metabolic activities to survive and it will die.

Having a large number of ribosomes benefits cells because it fastens the protein synthesis process in the cell. So large amount of protein can be produced in less time.
