________________ are hollow tubes of protein that maintain cell shape and permit movement of cell organelles

Answers

Answer:

Microtubules.

Explanation:

The main cytoskeleton of the cell is micro tubules, micro filaments and intermediate filaments. This structure helps to provide the stability and maintains the cell shape.

Microtubules are made of the polymers of tubulin. The microtubules are hollow shape like protein that forms the main part of the cyoskeleton. The microtubules maintains the cell shape and allows the movement of the cellular organelles of the cell.

Thus, the correct answer is microtubules.

Microtubules are hollow tubes of protein that maintain cell shape and permit movement of cell organelles.

The Amish population who migrated from Europe to the United States had very few individuals in their population. Additionally, their gene pool shows very few alleles due to inbreeding. A genetic trait called polydactyly (having six fingers), which is rare in other populations, is common amongst them. What kind of evolutionary effect is exhibited in this example?A. Mutation
B. Natural selection
C. Founder effect

Answers

The Amish have a genetic trait called polydactyly which is rare among other populations of people. This means that a person can 6 fingers, usually an extra thumb. This kind of evolutionary effect that is exhibited in this specific example is called the Founder effect. This happens when there is a small number of colonizing ancestors.

founder effect since it refers to migrating population

For the DNA base sequence GGG what is the mRNA codon? What is the tRNA codon that binds to the mRNA codon and what is the correct amino acid that is coded by the base sequence? ...?

Answers

Genetic code is said to be "degenerate" because many codons code for the same amino acid but NEVER will one codon code for more than one amino acid.
1. The DNA base sequence (GGG) is a CCC mRNA.
2. This mRNA sequence of CCC is known as the codon. It ill correspond to the tRNA anticodon of GGG.
3. This tRNA will be attached to the amino acid, proline.

I hope these answers help.

ccc
ggg
codes for proline
