Answer:D, gene pool.

Explanation: relative frequency can refer to the proportion of a particular genotype or phenotype in a population.

Phenotype is the physical expression of the genotype.

Genotype is the specific form of the alleles of genes

Gene pool is the totality of genetic variations in a population

Answer:

2

Explanation:

Answer:

A.

Explanation:

By the end of meiosis 4 daughter cells will be produced with half the amount of chromosomes the original parent cell has, haploid.

A cell with 20 chromosomes undergoes meiosis produces 4 daughter cells and each daughter cell will have 10 chromosomes. Thus option A  is correct.

The cell division in which a cell divides twice to form four haploid daughter cells called as Meiosis.

The cell division occur in two steps nuclear division or karyokinesis and cytoplasmic division called as cytokinesis.

This type of cell division are seen in sexually-reproducing organisms mostly germ cells.

During reproduction diploid organism produces haploid number of gametes such as egg and sperm.

The gametes unite to create a new zygote with the same number of alleles as the parents.

The meiosis occur in 2 stages that is meiosis I, meiosis II and  Each stage is classified into several phases such as Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.

Prophase I of meiosis I can have five subphrases, such as Leptotene, Zygotene,  Pachytene, Diplotene and Diakinesis.

Hence,  option A  is correct.

Explanation:

Answer:

The correct answer is D. Reduced levels of circulating estrogens.

Explanation:

Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

Answer:

The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates.

Answer:

Producers make their own food. They do not have to obtain energy from other organisms. They obtain their energy from the sun and make food with that energy through the process of photosynthesis. Producers may also be called autotrophs.

Answer:

4 genetically different haploid cells

Explanation:

meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

4 genetically different haploid cells.

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).

The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.

Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent.

Therefore, 4 genetically different haploid cells.

Answer: Helps keep the species alive

Explanation:

When the eggs are externally fertilized, there is a greater chance for multiple  different males to fertilize the eggs. This gives Gene diversity, and helps keep the species alive. It may also help keep the eggs in good condition. For example, when fish lay eggs, the water helps keep the eggs moisturized.
