Answer:
1. The daughter cells are genetically identical because they each contain the same diploid chromosome complement as the original parent cell. It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell.
2. Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.
3. The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.
4. – in cells capable of dividing, the period between cell divisions is called interphase – cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)
5. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. While all prokaryotes reproduce without the formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation, transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis.
6. Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids .

How does soil composition affect the number and types of organisms an environment can support?
(Biome majors)

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

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.
