The correct answer is option D, that is since genetic drift is random, it does not always favor the better or healthier organisms.
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
Answer:
The answer is option D.
Explanation:
A component of development in which the frequencies of alleles of a populace change with ages due to examining blunder is known as hereditary float. It happens in every one of the populaces of non-limitless size, be that as it may, its persuasions are most grounded in little populaces.
Asexual reproduction takes a variety of forms. The simplest one-celled organisms may reproduce by binary fission, in which the cells simply divide in half. This form of reproduction creates a clone of the parent, and has the benefit of usually being very quick and energy efficient. For example, bacteria that reproduce by binary fission can give rise to progeny every few hours.

The Answer is B because if we just look at the moles of nitrogen and oxygen they are in the ratio of 1:2. Since there are 3 moles with it, Even if we when we multiply this ratio by 3 the answer will be 3:6 and 6 is the double of 3 so B is the answer

Explanation:
When you cross a red snapdragon (RR) and a pink snapdragon (Rr), you will expect 50% of the offspring to have red flowers
In snapdragons, red and white flower color exhibits incomplete dominance, where the red (R) and white (r) alleles neither of them is completely dominant or recessive. This results in the heterozygous condition (Rr) appearing as pink flowers. In this case, the red flowered snapdragon would have a RR genotype, while the pink one would have a Rr genotype.
If you cross the red (RR) and the pink (Rr) snapdragons, the possible genotypes of the offspring would be RR and Rr, corresponding to red and pink flowers. Half of the offspring are expected to be RR (red), and the other half Rr (pink). Therefore, 50% of the offspring are expected to have red flowers.

Answer:
Option A- It allows for genetic variation among organisms.
Meiosis is important for organisms since it allows for genetic variation among organisms.
Further Explanation:
Mitosis and meiosis are two different types of cell division. Mitosis produces two daughter cells which are identical to each other. While in meiosis “four haploid” daughter cells are produced. It is a highly systematized cell division process as the spore or gamete produce must comprise one member of each homologous pair of the chromosomes. The crossing over results in genetic exchange between the non-sister chromatids of “homologous chromosomes”. Meiosis plays a significant role during the alternation of generation in plants and acts as a bridge between the sporophyte stage and gametophyte stage. During meiosis cell division, haploid gametes or spores are produced whereas mitosis produces daughter cells which are genetically similar to each other. During meiosis the pairing of homologous chromosomes occurs by synapsis which separate during anaphase.
