Answer:

Beginning of meiosis: 50 chromosomes

Chromosomes in each of the nucleus formed by meiosis: 25

Explanation:

Meiosis is a reduction division as it has two successive divisions without any intervening S-phase. It forms a total of four daughter nuclei each having half the chromosome number as present in the parent cell at the beginning of the process.

If a cell with 2n=50 enters meiosis, the segregation of homologous chromosomes to the opposite poles during anaphase-I of meiosis I would result in the reduction of chromosome number to the half in each of the two daughter nuclei formed by the end of the meiosis-I.

Meiosis-II is just like mitosis and maintains the chromosome number. So, the two daughter nuclei enter the meiosis-II and form a total of 4 daughter nuclei each of which has 25 chromosomes.

Which of the following is not a product of the light reactions of photosynthesis? 1) NADPH 2) NADH 3) ATP 4) Oxygen
n200080 [17]

Answer:

The correct option is number 2. NADH is not  product of light reactions of photosynthesis.

Explanation:

The light energy from the sun is captured by the pigmented molecule, chlorophyll, of the plants. This light energy is converted into chemical energy by a serious of light-dependent reactions. The main products of light-dependent reactions are the energy molecule ATP and NADPH. Oxygen is released as a by-product during photosynthesis. Hence, all the option 1,3 and 4 are produced during the light reactions except for option 2 i.e NADH.

The distance from one molecule in a body to the nearest molecule in the body occupying a similar position and moving in the same
creativ13 [48]
The answer is wavelength. It is the distance between corresponding points of two consecutive waves (corresponding points are particles or points in the same phase, meaning the points have completed identical fractions of their periodic motion. In a transverse wave it is the distance between two successful crests or troughs while in a longitudinal wave is the distance between two successful compressions or rarefactions.
