Explanation:

Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.

Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.

Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.

Cockroaches have 6 legs and each leg has 3 knees, 18 knees in total. Since the cockroach has so many joints in its legs its can accurately pick up speed when running away from something

An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.

Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.

Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

Answer:

Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes.

Water covers 70% of Earth's surface. When it comes to changes on the Earth's surface, the main processes to take into account are plate tectonics and the rock cycle as well as the sea-floor spreading. ... These collisions causes mountains and volcanoes to form on the plate boundaries and thus changes the shape and form of the landmass

Answer:

Chromosomes are tightly packed DNA and proteins. The DNA and proteins take on a tightly coiled structure within the chromosome. The chromosomes are then kept inside the nucleus. Their role is to carry basic genetic material. This provides the cell with genetic information that's used to carry out different cellular functions. These functions include survival, growth, and the ability to reproduce.
