Answer:

does it give you options like a multiple choice or just a word form your head

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.

Not all matter and waves move the same direction, some do though

Explanation:

transverse wave--matter in the medium moves back and forth at right angles to the direction that the wave travels

compressional wave--matter in the medium moves back and forth along the same direction that the wave travels

The one thing that you would see in a molecule that you would not see in a compound is the molecular bonds.

A Molecule may be defined as the smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms. These atoms are held together by attractive forces known as chemical bonds.

According to the context of this question, a compound depends on how many different kinds of elements make it up. Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. While a molecule has molecular bonds that togetherly held atoms in it.

Therefore, the one thing that you would see in a molecule that you would not see in a compound is the molecular bonds.

Answer: transfer of energy.

Explanation:

Answer:

Low; high.

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

Nocturnal animals possess a pathway through which rods connect to the same “dark” circuits used by cones, which allows them better perception of edges, movement, and silhouettes in dim light. Even the nuclei of the rod cells are adapted for night vision. ... One can only guess at what nocturnal animals see.

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.

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.

Explanation:

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.

Lastname, first name letter (year). Tesis Tittle. Graduation Level. Institution. City or Country.
