What do isotopes of an element contain?

Answer:

Its true.

Explanation:

Because if we are in bus we are not moving ,the bus is moving . And the things around which are in rest feels that we are moving. So comparative to them we are moving. But comparison to bus we are in rest because bus is moving and we are sitting inside bus .

Let us go option by option :

1) Genes are located in chromosomes. TRUE

Chromosomes are in cell nucleus. A chromosome contains hundreds and thousands of genes. A normal have 23 pairs of chromosomes, and a total of 46.

2) Chromosomes are the in nucleus.

TRUE

Chromosome is structure found in nucleus of the cell. It is made up of protein and DNA.

3) A single Chromosome can contain hundreds of genes.

TRUE

single Chromosome can contain hundreds of tgenes.

4) All of the above

TRUE

As all the statements above are true. The correct option is 4.

Answer:

all of them are true

Explanation:

this is because chromosomes contain genetic materials and it is present in the nucleus.
Therefore, the correct option is 4) all of these are true

Explanation:

The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed. In order for fossilization to occur, the remains have to be covered by sediments and stay undisturbed for thousands of years.

Answer:

The neutron was the last of the atomic components to be discovered because it does not have an electric charge, making it difficult to detect. It was also not predicted by early atomic theories, leading scientists to believe that the atomic nucleus was composed solely of protons. The discovery of the neutron required the development of new experimental techniques, such as neutron scattering, to detect its presence.

Answer:

A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1

Answer: hydrogen-carbonate.

Explanation:Because when carbon dioxide is passed in excess it leads to a formation of hydrogen-carbonate.

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

The two ways that the hydrosphere affects the geosphere for this kind of coastline include:

This is the process in which earthen materials are worn out and transported to other locations via agents such as wind and water.

Hydrosphere erodes materials on the Earth as a result of water movement and is also responsible for deposition of nutrients from water bodies to the geosphere.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
