Studentka2010 [4]3 years ago
6 0

Answer:

All of the above

Explanation:

The nucleus constitute DNA-protein complex termed chromatin. Chromatin is simply DNA  double helix entwined around proteins referred to as histones. These appear like beads when  stretched out, and each “bead” (DNA and histone) form the nucleosome. Genes are hereditary materials found on DNA. Chromosomes are composed of closely-packed chromatin, and become clearly visible  under a microscope during mitosis. During this stage the chromosomes have undergone the S Phase of the cell cycle, hence a copy of the DNA has been synthesized by DNA polymerase.

kow [346]

Answer:

B. He believed that sexuality is a continuum and wanted to classify people more precisely

Explanation:

Kinsey quantified in his studies heterosexuality and homosexuality on a continuous scale from 0 to 6, specified in heterosexual and homosexual experience and reactivity in each story. 0 on this scale is assigned to individuals with exclusively heterosexual sexual contacts and experiences and 6 to exclusively homosexual individuals.

He proposed a model according to which there are many intermediate degrees between heterosexuality and homosexuality. This gradualness was embodied in what is now known as the Kinsey scale.

Part C
AnnyKZ [126]

The style is the female reproductive part of the plant. it plays important role in plant breeding .

What is style and the role of style in reproduction ?

The stigma and ovary are connected by a long tube-like structure called the style. The pollen tubes bearing male gametes enter the style tissues and travel to the ovary's ovule once the stigma's pollen grains have germinated. Once within the embryo sac, it travels to the egg cell to fertilize it with the aid of the filiform apparatus.

The style is crucial to the plant reproduction  process since it not only serves as the site for the formation of the pollen tube but also functions to prevent incompatible pollen from entering the ovary. Genetic information is transferred between the pollen and the plant when the pollen tube begins to spread within the style. The plant also produces a poison at this period. The plant will release the poison to block the formation of the pollen tube if the pollen is unsuitable because it comes from a different species or is too closely related, leading to inbreeding.

If the pollen is compatible, the plant will isolate the poison and sequester it so that the pollen tube growth is not halted. Therefore, the style is the area where compatibility is evaluated and where it is decided if pollen that falls on a flower will be allowed to fertilize the plant.
