Answer:
Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

Answer:
As a transcription factor
Explanation:
Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.
The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.
The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.
Thus, as a transcription factor is correct.
Answer:
The correct answer is the growth of the offspring to adulthood.
Explanation:
A life cycle is illustrated as the stages of development, which take place during the lifetime of an organism. A life cycle ceases with the death of an organism. Generally, the animals and plants go through three fundamental stages in their life cycles, beginning as a seed or fertilized egg, developing into an undeveloped juvenile, and eventually turning into an adult.
During the stage of adulthood, a species will reproduce, forming a new generation. A life cycle can constitute more than three fundamental stages on the basis of the species. For example, the life cycle of a human being comprises five main stages.
Explanation:
All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Most animals are motile, at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic, ingesting living or dead organic matter.
