<h3><u>Answer;</u></h3>
peptidoglycan
The molecular basis of the Gram stain is the amount of<u> peptidoglycan</u> in the bacterial cell wall.
<h3><u>Explanation</u>;</h3>
- Gram stain is differential stain that is very useful for identifying and classifying bacteria as either gram negative or gram positive.
- Gram negative are those that decolorize easily, such as E. coli, while Gram positive are those that retain the primary stain and do not decolorize easily.
- The result depends on the bacteria cell wall structure, the cell wall of a Gram-negative bacterium is composed of 20 percent or less of peptidoglycan.
Answer:
B. Row x describes meiosis and row y describes mitosis
Explanation:
- <em><u>Mitosis is the process in which a cell divides to yield two daughter cells with same number of chromosomes as the parent cell. </u></em>The process takes place in the somatic cells or the body cells. For example, a cell with 14 chromosomes divides to produce two cells with 14 chromosomes.
- <em><u>Meiosis on the other hand is the process in which a cell divides into four daughter cells that have half the number of chromosomes as the parent cell.</u></em> The process takes place in the germ line cells where gametes are produced. For example a cell undergoes meiotic division to produce four cells each with 7 chromosomes.
Answer:
1. The offspring will be all tall pea plants
2. 3:1 is the ratio for tall and short
<span>Answer is letter D which is “all eukaryotic cells”. The cellular respiration occur in all eukaryotic cells has a metabolic reaction and processes that happens in the cells of an organism to change it into a biochemical enegergy unlike photosynthesis it only occurs in cells having chloroplast</span>
I think zoe because you can’t just test which one is the best it’s too broad to investigate
