How important is it for a cell to maintain the same number of chromosomes? Explain.

Answers

Answer 1

Answer:

It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

1. Give 2 similarities between each of the skulls that might lead to the conclusion that these are all related.

2. What is the biggest change in skull anatomy that occurred from the dawn horse to the modern horse

Answers

Complete question:

You will find the image of the skulls in the attached files.

Answer:

1) 2 similarities between each of the skulls might be the presence of the nasal spine, and the interdental space.

2) The size of the skull seems to be the most noticeable change in skull anatomy between the dawn horse and the modern horse.

Explanation:  

Each of the nasal bones in horses ends in a protuberance named "the nasal spine". These spines converge in the distal portion of the bone. These spines and the incisive bone delimitates the space called the naso-incisor notch. In the attached figure you will see the nasal bone in red and the nasal spines. This structure is present in all the skulls in the same position.  The interdental space is the space left between the front teeth and the back teeth. It is useful to recognize a male from a female in modern horses. This space can be found in all the skulls. You will see it in blue in the image.  

The biggest change in skulls between the dawn horse and the modern horse is the size. The skull keeps the original shape or very similar shape but varies in length and height.  

The two (2) similarities between each of the skulls that shows that they are all related include:

They all have a similar ridge that typically protrudes from the top.Each of the skulls have a set of flattened teeth.

What is an evolution?

Evolution can be defined as a process of gradual change in the characteristics and genetic make-up of the species of a living organism over several generations.

In Genetics, a scientific technique which is commonly used to determine evolutionary relationships between organisms is the study of their fossils and biochemical similarity.

The similarities between each of the skulls.

Thus, the similarities between each of the skulls that shows that they are all related include:

They all have a similar ridge that typically protrudes from the top.Each of the skulls have a set of flattened teeth.All the skulls have the same overall shape.

Additionally, the biggest change in skull anatomy with respect to the dawn horse and modern horse is that the modern horse has a larger skull.

How does the carbon cycle support the Law of Conservation of Mass?

Answers

The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

The carbon cycle supports the Law of Conservation of Mass, as the law states, the carbon also reuse and reabsorb in the carbon cycle.

What is the carbon cycle?

The carbon cycle is the movement of carbon from the atmosphere to plants and organisms. Carbon is coal when burned turn into gas.

The majority of carbon is kept in rocks and sediments; the remainder is kept in the ocean, atmosphere, and living things.

According to the Law of Conservation of Matter, matter can be created or destruct. Because the carbon cycle recycles the same carbon atoms, it serves as an illustration of the Law. Some carbon is stored for future growth, and some are used for energy.

Thus, because carbon is reused and reabsorbed in the carbon cycle, the Law of Conservation of Mass is supported by this law.
