D. Organisms only need water
A) a common ancestor
Homologous structures are structures that are similar in related organisms. There is a basic pattern of bones which can be inherited from a common ancestor
Answer:
The cell with chloroplasts, abundant ribosomes, plus an endoplasmic reticulum, and a cell wall is of the plant cell type.
Explanation:
Plant cells are eukaryotic cells found in all plants, with specific characteristics given their ability to be autotrophic and use solar energy to synthesize their nutrients. The presence of many ribosomes and a developed endoplasmic reticulum is due to their high capacity for plant protein synthesis.
One characteristic that differentiates plant and animal cells is the presence of a cell wall, which surrounds the cell membrane, and chloroplasts. Chloroplasts are responsible for making the process of photosynthesis possible.
Answer and Explanation:
A restriction enzyme is a type of endonuclease enzyme that recognizes a specific short nucleotide sequences on the DNA and cuts the DNA only at palindromic sites. There are different types of restriction enzymes:
1. Type I restriction enzyme – It cuts at sites far from the recognition site and requires both ATP and S-adenosyl- L-methionine as cofactor to function.
2. Type II restriction enzymes – It cleaves at short-specific distances from the recognition site and mostly requires magnesium to function.
3. Type III restriction enzymes – It recognizes two separate non-palindromic sites and cleaves at 20–30 base pairs away from a recognition site. It requires both ATP and S-adenosyl-L-methionine .
The restriction enzymes cleave DNA sequences producing either sticky or blunt ends that can be ligated with other sequences.
The answer is different chemical properties or molecular properties.
