Hemophilia is an X-linked trait caused by the allele h. About 1 in 10,000 males (0.0001) has hemophilia. The frequency of the h allele in males is therefore
.
Answer : 0.0001
Explanation:
Since males only have 1 X chromosome, the number of males with h alleles should be equal to number of males with Haemophilia and therefore the frequency of males with Haemophilia must be equal to the frequency of h alleles on X chromosome.
The presence of a cholesterol in the plasma membrane of some animals
Answer:
The amount of cholesterol in animal plasma membranes regulates the fluidity of the membrane and changes based on the temperature of the cell's environment. In other words, cholesterol acts as antifreeze in the cell membrane and is more abundant in animals that live in cold climates.

Which is the better soil amendment: compost, vermiculite, and manure? Why?
Answer:
All of them are great, but compost and manure are probably best because they still have protiens and energy stored in them.
Have an awesome day friend! :D
Explanation:
Compost: (permeability, water retention, nutrients) Well-rotted compost is one of the best soil amendments you can add to your garden, and it’s impossible to use too much! Compost is highly fertile and lightens heavy soils while providing structure to loose soils. It also possesses the amazing ability to help soil retain much needed water while improving drainage – making compost great for both clay and sandy soils. Compost lasts about six months but has a long-term impact on soil microbes and overall fertility. Continue to add compost, and watch your soil get better and better.
Greensand: (provides permeability, nutrients) This powdered rock material provides slow release nutrients, such as potassium and other trace minerals. It also helps loosen compacted soil.
Sand soil amendment
Sand soil amendment.
Gypsum: (permeability for saline soils) While powdered gypsum is considered an amendment for clay soil, it’s actually more important for saline soils where it loosens the clay by reacting chemically with the salts.
Leaf Mold: (water retention, texture, nutrients) Made from shredded, composted leaves, leaf mold holds moisture, loosens soil, provides organic matter, and breaks down slowly to improve overall soil texture. Leaf mold also encourages beneficial microbes that help transfer nutrients to plant roots.
Manures: (texture, nutrients) Composted manures are affordable, readily available soil amendments. Like other forms of compost, manure provides the right balance of drainage and water retention. Manures are high in nitrogen and other nutrients, so they’re particularly useful as slow release fertilizers. Manures can add salt to the soil, so they may not be suitable if your soil is already saline. Use only well rotted manure to prevent burning due to high nitrogen content.

3)What are some examples of specialized cells
and what do they do?
4) Why is the specialization of cells in organisms
significant and important for homeostasis?
Answer:
3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.
Explanation:
4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.

Which statement describes a social benefit of the sustainable use of land?
Sustainable farming of land can provide food to support a large global population.
Shared land use will protect habitats and increase the biodiversity of ecosystems.
Cutting down more trees will provide materials to build more affordable housing.
Companies will increase profits by dumping waste on public land.
Answer:
It would be the first one
Explanation:
I am sure it would be this because when farming, you are not harming the environment or any other ecosystems in anyway. It would also supply food for a constant growing population. Let me know if this helps!
Sustainability is defined by the maintenance of the factors. Sustainable land farming can supply food to support global inhabitants. Thus, option A is correct.
What is sustainable land use?Sustainable land use is the practice of using and managing the land effectively by the fair use and distribution of environmental resources like land so that it can be secured for future use.
It involves the indiscriminate usage of land resources with no negative effects or consequences that have rather a positive impact on the environment.
The use of farming land in a sustainable manner can ensure the growth of agricultural food in efficient amounts so that it can support the need for food for the global population.
Therefore, option A. the farming of land to support global food demand is a social benefit of sustainable land use.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

What happens to the tides if the earth spinner fast??
Answer:
it would be a disaster
Explanation:
The centrifugal force would pull hundreds of feet of water toward the Earth's waistline.
Answer:
If the Earth were to spin faster, the tides would change because the fast speeds would increase stress; making tighter circles of convection. This would cause more natural disasters like hurricanes, cyclones, and tsunamis.

If you place yeast, sugar and water in a sealed bag and in the sun , what two things will be produced
Answer:
Explanation:
The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.
While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.

The star in the diagram represents which of these? A. origin of replication B. replication fork C. replication bubble D. Okazaki fragment
Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.
During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.
The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.
