Answer:

Evolution

Explanation:

The concept of growth and development and changes , or the hypothesis that species have evolved and formed from previous species, is referred to as evolution. Biological evolution of an organism' features changing over many generations by natural selection. Genetic diversity is needed for evolution to occur.

Answer:

It allows to see objects more clearly.

Explanation:

Magnification and resolution greatly affects the appearance of objects that can be seen under a microscope​ because these two things make the specimen enlarge in size. Magnification refer to the process of enlarging the apparent size of something to see and observe it clearly while on the other hand, resolution is used to see more details about specimen that can be study in the microscope so we can conclude that both magnification and resolution has a great impact on the appearance of objects.

Pangaea came together during the Phanerozoic eon.  

• The current geologic eon in the geologic time scale is the Phanerozoic eon. It is the one during which abundant plant and animal life prevailed.  

• It is of the span of 541 million years to the present, and it started with the Cambrian period when animals initially developed hard shells.  

• The Phanerozoic time span began with the sudden emergence of fossilized evidence of a number of animal phyla, the development and emergence of complex plants, and the evolution of fish, the emergence of tetrapods and insects, and the development of present time fauna.  

• During the Phanerozoic eon, the tectonic forces moved the continents and gathered them into a single landmass called Pangaea, which later got separated into the present continental landmasses.  

Thus, the correct answer is Phanerozoic eon.

Explanation:

rRNA is ribosomal RNA

tRNA is transfer/transport RNA, and it brings amino acids to the ribosomes so they can make proteins.

mRNA is messenger RNA

Hope it helps :)

Answer:

rRNA makes up the ribosome.

tRNA carries amino acids to ribosome.

mRNA copies the genetic code from DNA and carries it to the ribosome.

mRNA code is read to determine the sequence of amino acids in the protein.

Explanation:

Answer:

Both can occur in the same environment. Both can affect the same animals. Both depend on the environment.

The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes. ... A chromatid, then, is a single chromosomal DNA molecule. In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.

Answer:

At each level in a food chain, some energy is stored in newly made chemical structures, but most is dissipated into the environment.

Explanation:

The division of the cytoplasm is known as Cytokinesis. It occurs during the later part of the division of the nucleus in both mitosis and meiosis. In Cytokinesis, the cytoplasm of a single parent cell divides in two to produce two daughter cells.

Cancer is a disease condition that results when the growth and division of cells is uncontrolled. It occurs as a result of changes to the DNA either due to environmental factors or heredity factors.

Metaphase is one of the four stages in mitosis. During mitosis, the chromatids which are joined at the centelomere line up at the middle or equator of the cell.

Centromere is a region in the chromosome in which sister chromatids are joined together to form a short and a long arm of the chromosome.

A tumour is a swelling of a part of the body due to the abnormal growth of cells in that part of the body. A tumour may have the ability to spread or not.

Cancers that originate in the skin or tissues lining organs is known as carcinomas.

In plants, meristematic tissues are responsible for growth as they consist of actively dividing or mitotic cells. Meristematic cells are present at the tips of roots,stem and branches.

Carcinogens are agents or factors that are able to cause cancers. They include such agents like chemicals, electromagnetic radiations, some viruses, lifestyle factors, etc.

Benign tumours refers to growths in tissues or organs of the body which are non-cancerous as they do not spread to other tissues or organs in the body.

A chromatid is one-half of a replicated chromosome present in the nucleus of the cell. Two chromatids are joined together at the centromere to form the chromosome.

Answer:

The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.

Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.

Explanation:

If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.
