I just had this question

Explanation:

In order for a population to survive, sexual reproduction must produce A) more females than males. B) more males than females. C) more offspring that can survive and reproduce. D) a large number of self-fertilized individuals.

Answers

The answer is C) more offspring that can survive and reproduce.

In order for a population to survive, there must be enough offspring at least to maintain the number of population. It is better if there are more offspring able to survive and reproduce and species evolved different strategies to achieve this, such as care for the offspring.
On the other hand, neither more males nor more females will help a population to survive. There will be no variability in a gene pool because one male will cross with many females and vice versa. And with greater variability of characteristics, the greater is the chance to survive. Also, a large number of self-fertilized individuals could not be the right answer because this is an example of asexual (self-fertilization) reproduction.

c. more offspring that can survive and reproduce.

List three signiﬁcant differences between meiosis I and meiosis II

Answers

Meiosis 1 starts with one cell, ends with two.
Meiosis 2 starts with two cells, ends with four.

Meiosis 1 lines up with homologous pairs (Metaphase 1).
Meiosis 2 lines up straight in a line with no pairs (Metaphase 2).

Meiosis 1 one goes from Diploid to Haploid.
Meiosis 2 goes from Diploid to Diploid.

The three significant differences between meiosis I and meiosis II: Chromosome pairing and recombination, Number of chromosomes, and Recombination events.

1. Chromosome pairing and recombination:

Meiosis I: During prophase I of meiosis I, homologous chromosomes pair up and undergo genetic recombination (crossing over) where genetic material is exchanged between non-sister chromatids. This results in increased genetic diversity.

Meiosis II: Chromosome pairing and recombination do not occur in meiosis II. Instead, the goal of meiosis II is to separate the sister chromatids produced during meiosis I.

2. Number of chromosomes:

Meiosis I: At the start of meiosis I, the cell is diploid (2n), meaning it has a full set of chromosomes. Homologous pairs of chromosomes align and separate during anaphase I, resulting in two haploid cells with half the number of chromosomes (n) as the original cell.

Meiosis II: The cells resulting from meiosis I enter meiosis II. The number of chromosomes remains the same throughout meiosis II. Sister chromatids separate during anaphase II, resulting in the production of four haploid cells.

3. Recombination events:

Meiosis I: Meiosis I allows for recombination events between non-sister chromatids of homologous chromosomes. This crossing over increases genetic diversity and introduces new combinations of alleles.

Meiosis II: Meiosis II does not involve recombination events. Instead, the focus is on separating the sister chromatids that were produced during meiosis I, ensuring each resulting cell receives a complete set of chromosomes.
