How many chromosomes do each ending cell of meiosis contain
Viefleur [7K]

(See figure below, where meiosis I begins with a diploid (2n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).

blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω

In terms of adaptation, what advantage does sexual reproduction provide for species
KengaRu [80]
Unlike other ways of reproduction, sexual reproduction provides variation through inheriting various genes. This variation is essential for adaptation as it would not just create a copy of the original life form, but rather a different unique life form that could adapt to something, and then have it's own offspring with the adapted trait.

How is it possible that over 20 million living organisms on the planet are made up of only 5 types of nucleotide based arranged
almond37 [142]

Answer/Explanation:

The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.

Imagine an organism exists that has only 2 nucleotides (<u><em>this is over 200,000x smaller than even the smallest bacterial genome</em></u>). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.

Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.
