2. What are the two major subdivisions of the nervous system, and what does each division do?

Answers

Answer:

2 Major Subdivisions:

Central Nervous System

Peripheral Nervous System

Explanation:

The central nervous system (CNS) regulates the majority of bodily and mental activities. It is divided into two parts: the brain and the spinal cord. The brain is the core of our ideas, the translator of our surroundings, and the source of control over physical action.

The PNS is the nerve that links the CNS to the rest of the body. The peripheral nervous system's principal job is to link the brain and spinal cord to the rest of the body and the outside world. The peripheral nervous system sends and receives information to and from the central nervous system. This is done by neurons that convey information from sensory receptors in the eyes, ears, skin, nose, and tongue, as well as stretch receptors and nociceptors in muscles, glands, and other internal organs.

Summary about DNA , Genes , Traits , Chromosomes. (Explain & let me know about all 4 words. Summarize all these words.) Write about how all 4 things work together.

Answers

Answer:

Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus. And a trait is a gene-determined characteristic.

which is responsible for genetic diversity.

Answers

Answer: Crossing over

Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️

The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.

What is Crossing over?

Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.

Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.

Therefore, the correct option is B.

what process can lead to an individual having too many or two few chromosomes?

Answers

The process which can lead to an individual having too many or two few

chromosome is as a result of mutation which occurs during meiosis.

Meiosis is the type of cell division which occurs in reproduction and the

production of sex cells such as sperm and egg. This process results in the

production of four unique daughter cells.

The homologous chromosomes not being properly distributed in the

process could lead to such types of error.

Answers

Answer:

1. Light penetration

2. Distance from shore

3. Depth of water

4. Temperature

5. Amount of nutrients/salt

Explanation:

Oceanographers use various methods to determine vertical and horizontal zones in the ocean. First and foremost are the distance from the land and the depth of the water. These contribute to the other factors, such as temperature and light penetration. They also measure how much salt or nutrients are available at that zone, which plays a role in how much life is discovered in the location.

The photic and mesopelagic zones are mainly grouped by light penetration, while mesopelagic, abyssopelagic, hadalpelagic, benthic, and bathyal zone are categorized by depth and temperature. When looking at the pelagic zone, the neritic and the oceanic sections are differentiated by the distance from the land.

Answers

kinetic energy is needed by the molecules in order to escape from the surface.

All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.

Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

which microscope would be best to look at the wings of two different butterflies to determine which is a monarch butterfly and which is a viceroy butterfly?

Answers

SEM microscope should be

To determine the difference between a monarch butterfly and a viceroy butterfly, it would be best to use a microscope that has high magnification and resolution, such as a compound light microscope or an electron microscope.

What is a microscope?

A microscope is an optical instrument that is used to magnify small objects or details, such as cells or tissues, so that they can be studied or observed more closely. There are various types of microscopes available, including compound light microscopes, scanning electron microscopes, and transmission electron microscopes, which use different principles to produce magnified images of the objects being examined.

A compound light microscope would allow you to see the structures of the wings in detail, while an electron microscope would provide even higher resolution images, but would require the wings to be coated in a thin layer of gold or other metal in order to be viewed. Both of these types of microscopes would allow you to see the fine details of the wings and compare them to determine which is a monarch butterfly and which is a viceroy butterfly.
