How would you explain the outcome of mendel's experiments with pea plants s?

1 answer:

5 0

-Mendel discovered that true breeding of Tall plants (T for dominant) are crossed with true bred short plants (t for recessive).The next generation of plants are known as F1 and are tall plants (T)

-he showed that self-pollinated first generation (F1) plants produce an F2 generation with 75% of tall plants (T) and 25% short (t)

Which type of cell is most likely to have the most mitochondria? muscle cells in the legs of a marathon runner nondividing cells

MatroZZZ [7]

Answer:

muscle cells in the legs of a marathon runner

Explanation:

Mitochondria are the powerhouse of cells and serve as a site for the aerobic stage of cellular respiration. Cellular respiration is complete oxidation of nutrients in the presence of oxygen to produce a large number of ATP molecules. Therefore, the cells that require more ATP molecules as an energy source would most likely have a greater number of mitochondria.

Muscle cells are responsible for body movement. Muscle cells in the legs of a runner would require a constant supply of ATP during running since muscle contraction requires ATP. To sustain the continuous muscle contraction during the marathon, the muscle cells in the legs of the runner would have most number of mitochondria.

ASAP test tomorrow how is " produces " represented in a chemical reaction ?

sergeinik [125]

In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.

Hopefully this helps!
