The correct answer is: B. spinal cord  

The nervous system can be divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and the brain are part of the CNS, whereas the PNS consists of the nerves that radiate from the CNS to all parts of the body. The PNS includes all neurons that sense and transmit information to the CNS.

The CNS controls thinking processes, movements, and registers the sensations throughout our body. Moreover, the PNS acts to transmit information from the CNS to all parts of the body.

The PNS is in turn divided into two main parts:

1-The Autonomic nervous system (ANS), which regulates involuntary functions and glands. The parasympathetic nervous system is one division of the ANS that controls visceral organs such as glands.

2- Somatic nervous system (SNS), which regulates voluntary muscle movement and transmits information from eyes, ears, and skin to the CNS.

The significant difference between a park and a nature reserve is that a park is considered an ecological island; a nature reserve cannot be considered an ecological island (option D)

A park is an area of land set aside for environment preservation or recreation. A park can be created near a city or town, enclosed and kept for ornament and recreation.

A nature reserve, on the other hand, is an area of land managed to conserve wildlife or plant habitat or other natural features.

Therefore, the significant difference between a park and a nature reserve is that a park is considered an ecological island; a nature reserve cannot be considered an ecological island.

Answer:

A. parents: Hh and Hh

B. chances of being a carrier: 50%

C. 50%

Explanation:

A. Since hemophilia is a recessive trait, both parents must carry the recessive alelle for it to show through in the child. However, we know both of them are phenotypically normal, meaning a dominant trait (not hemophiliac, H) is masking the recessive trait (hemophiliac, h)

B. The options the woman has when you create a punnet square with her parents genotypes are HH (doesn't have any hemophilia, because hemophilia is recessive, so represented with a lower case h) Hh (there is twice the likeliness she is an Hh since it occurs two times when you combine her parents genotypes. Hh means she is a carrier, but does not have the trait) and hh (meaning she definitely has it). So there is four options, two of which mean carrier, meaning she has a 50% chance of being a carrier.

C. genotypes of the parents:

mom: Hh

dad: hh

when you create their punnet square, you will get two occurrences of Hh and two occurrences of hh. Remember that hh means hemophilia. This means the child has a 50% chance of having hemophilia.

References prove the quality and reliability of a research document. They must be properly written, including the author's name, title, year, and URL if needed.

When writing a document about a research work, it is important to list the sources used during the investigation  

One of the main priorities is to provide trustworthiness. The research must prove its quality, so should be based on reliable information and methodology.

When looking for information, we always need to look for reliable scientific information. These are investigations previously carried out by other researchers and evaluated by qualified professionals.

We can find scientific information in books, encyclopedias, scientific journals, and magazines, among others. These sources can be found on the web or printed out.

While writing the document, it is necessary to avoid plagiarism and to cite and make a reference to every consulted material.

Cites are placed in the middle of the document, while references are listed at the end.

There are different methodologies used to list sources. For instance,

Lastname, first name letter (year). Book Tittle (edition). City or Country: Publisher.

Lastname, first name letter (year). Chapter Tittle. In Lastname, first name letter. Book title (pages pp. Xx-Zz). City or Country: Publisher.

Answer:

Plant reproduction is the development of new offspring that can be achieved through sexual or asexual reproduction in plants. By the fusion of gametes, sexual reproduction creates embryos, resulting in offspring genetically distinct from the parent or parents. Asexual reproduction creates new individuals, genetically similar to the parent plants, without the fusion of gametes.

Seaweed being eaten by a turtle is an example of an organism providing energy to a primary consumer. Therefore, the correct option is A.

The seaweed is a primary producer that captures energy from the sun through photosynthesis and converts it into chemical energy stored in organic compounds. The turtle is a primary consumer that obtains energy by consuming the seaweed.

Option B is incorrect because both the shrimp and the codfish are consumers. Option C is incorrect because this is an example of decomposition, which is the breakdown of organic matter into simpler compounds by decomposers such as bacteria.

Option D is incorrect because the oak tree is a primary producer that captures energy from the sun through photosynthesis. Therefore, the correct option is A.

Explanation:

A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.

Basically, a microscope is used for viewing very little objects, microorganisms and cells found in living organisms such as humans, animals and plants.

The interchangeable lenses found in a microscope which are close to the specimen being observed are called objective lenses. These objective lenses comprises of low power objective and high power objective. To see a general view of a microscope slide, use low power. If you need to see a more specific and detailed view, use high power.

Hence, the field of view (FOV) is largely dependent on the objective lens being used, it is largest (general view) for low power and smallest (specific and detailed view) for high power.

Answer:

Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.

Explanation:

Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.

Nitrates and phosphate found in water are usually from plants that  have been washed off by rain water and also from vehicles' exhaust.

When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).

This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a  swamp and eventually a meadow
