The structure in this figure shows one complete nucleosome is structure D.

Nucleosome is the structural building block of DNA packaging inside the chromosome. The packing problem of how to fit a very, very long stretch of DNA, that is, about a yard of DNA, inside a very small cell, which is about one hundredth of a millimeter in diameter, has fascinated scientists for a long time.

And it turns out how does the cell do this -- now -- remember that every single cell in the body has this problem -- is it coiled and super coiled around DNA in a lot of complicated ways.

The basic building blocks of the coil are the nucleosomes, which are basically the little blocks of histone proteins around which the DNA is wrapped, and they really look like beads on a string, except the beads have DNA wrapped around them rather than have DNA running through them, as in the case of the beads on a string.

In order to fit DNA into the nucleus, it must be packaged into a very compact structure known as chromatin. In the first step of this process, the DNA is compacted into 11 nm fibers representing a 6-fold compaction level. This is achieved through nucleosome assembly.

Each nucleosome consists of a core of octagonal octamers, which are assembled from histones H2A, H2B, H3 and H4 (or other histone variants in some cases) and a DNA segment that wraps around histone core. Adjacent nucleosomes are linked via “linking DNA”.

If the root tips of a plant were cut and the plant was replanted, it would likely experience some stress as it adjusts to its new environment.

The root tips are important for the plant's growth and nutrient uptake, so cutting them may affect the plant's ability to access water and nutrients from the soil. In addition, replanting can also be stressful for a plant, as it requires the plant to establish new roots in the soil and adapt to any differences in light, temperature, and humidity in its new location.

It is possible that the plant may wilt or appear to be struggling initially, but with proper care and attention, it may eventually recover and continue to grow. To help the plant recover, it is important to provide it with adequate water, light, and nutrients, and to be mindful of any environmental factors that may be affecting its growth.

No, the cardiovascular system does not help move hormones throughout the body. The cardiovascular system is in charge of delivering nutrition, hormones, and oxygen to the body's cells.

However, hormones are not transported by the cardiovascular system. Instead, hormones are transported through the bloodstream by proteins called carrier proteins. Carrier proteins bind to hormones and transport them to target cells, where they can bind to receptors and cause a response.

The cardiovascular system is responsible for transporting these carrier proteins, but it does not directly transport hormones. Additionally, hormones can also be transported through the lymphatic system, which is a separate system from the cardiovascular system.

The lymphatic system is responsible for transporting white blood cells, lipids, and other substances throughout the body. Therefore, the cardiovascular system does not help move hormones throughout the body.

The genotypes AA and Aa always show up as the dominant.

Genes are the material that carries the properties of the parent and are passed on to their filial or offspring. Genes are attached to chromosomes and chromosomes are contained in the nucleus or cell nucleus.

Chromosomes in the body are usually in pairs. In humans, there are 46 or 23 pairs of chromosomes. 22 pairs are autosomal chromosomes, namely the chromosomes that make up the body, such as the eyes, nose, legs, hands and other organs.

One more pair is called the genosome chromosomes, namely the sex chromosomes, the chromosomes that determine the sex of the individual. When the chromosomes pair X and X (XX), the sex is female. And if the chromosome pair is X and Y (XY), then the sex is male.

Chromosomes contain genes and the inherited genes are dominant and recessive. Dominant trait means, a trait that dominates and overpowers other traits. For example, both parents have olive and black skin tones. And it was obtained that all of his offspring had olive skin color.

This means that the olive skin color gene is dominant over the black skin color gene. The black gene is called a recessive gene, that is, a gene that is hidden and defeated.

1. To calculate the slope of the ground surface on either side of Jim's Gas Station, an elevation survey would have to be taken to determine the change in elevation in relation to the distance traveled. This can be done with a topographic map or an altimeter.

A topographic map is a type of map that uses contour lines to show the shape of the land and its features.

2. The slope of the water table at Jim's Gas Station can be estimated by measuring the depth of the water table in relation to the topography of the land in the area. This can be done by measuring the depth of the water table at various points around the gas station and then plotting them to see how the depth of the water table changes with respect to the topography.

3. The direction of the pollution plume can be inferred by looking at the slope of the ground surface and water table. If the ground surface slopes downward away from the gas station, the pollution plume is likely to move in the same direction.

4. The houses and bodies of water that are threatened by this pollution plume are those that are located downhill from the gas station. The further downhill the houses and bodies of water are, the more likely they are to be affected by the pollution plume.

5. The path of the pollution plume at Jim's Gas Station can be predicted by looking at the slope of the ground surface and water table. This is because the pollution plume will move in the direction of the downward slope of the ground surface and water table. The path of the plume can be further refined by taking into account other factors such as wind direction and speed, temperature, and humidity. By taking all of these factors into consideration, a precise prediction of the path of the plume can be made.

No, muscular strength and body mass do not increase at the same rate. The force a muscle can generate in opposition to a resistance is a measure of muscular strength. Body mass is determined by the total amount of fat, muscle, and bone within an individual’s body.

Muscular strength can increase at a much faster rate than body mass. This is mainly due to the fact that muscles can be trained and strengthened much quicker than fat and bone can be added. For example, a person can lift weights and build muscle strength in a matter of weeks, while it can take months to build body mass.

In addition, muscular strength can increase without an increase in body mass. An individual can use resistance training to increase their muscular strength without necessarily increasing their overall body mass.

The evolutionary theory proposed by Alfred Russel Wallace is a model to explain variation in nature based on the enviroment as the trigger of these changes instead of inheritance, which is opposite to the observations of Darwin who indicated variation is the primary matter of evolution.
