Why is the reduction in chromosomes number important in meiosis?

Biology
1 answer:
valkas [14]3 years ago
3 0

Explanation:

Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

True or false: homologous chromosomes separate during mitosis?
Tcecarenko [31]

Answer:

Homologous chromosomes do not function the same in mitosis as they do in meiosis. Prior to every single mitotic division a cell undergoes, the chromosomes in the parent cell replicate themselves. The homologous chromosomes within the cell will ordinarily not pair up and undergo genetic recombination with each other.

To identify the molecule that accepts CO₂ , Calvin and Benson manipulated the carbonfixation cycle by either cutting off CO₂ or
Alexxandr [17]

To identify the molecule that accepts CO_{2}, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off CO_{2} or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The CO_{2} acceptor concentration would increase when the CO_{2} is cut off, but decrease when the light is cut off.

The correct option is d.

The process through which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules is known as carbon fixation. These substances are employed as chemical energy storage. For life to continue, it is a necessary process.

Calvin and Benson disrupted the carbon-fixation cycle by either removing CO_{2} or removing light from cultures of photosynthetic algae in order to find the molecule that takes CO_{2}. Following the alteration, they evaluated the concentrations of several metabolites.

PLease Help 2. Instantaneous speed is the rate of motion of an object at a particular moment in time. What change(s) to the expe
yKpoI14uk [10]

To gather data on instantaneous speed via experiment, we can use limits i.e. using limits in the formula for example 1 second and 2 second interval with particular difference of distance traveled by object during this interval. for example if distance traveled after 2 second is 60m and after one second is 35m, then the speed will be the ratio of differences of distances and time intervals.
