Answer:
X-linked recessive inheritance
Explanation:
Since the disease is primarily present in males vs females, it is a s.ex linked disease.
In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.
Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.
B)Is gold heavier than silver?
C)Do apples taste better than oranges
Answer:
B): Gold is in fact heavier than silver. Smaller gold objects will be heavier than silver objects even if they're both the same size.
C): I cannot answer this question because it would be an opinion. Both are good in nutritional value.

Evidence of evolution
Natural selection has to do with organisms being best suited for their environment surviving and reproducing more often.
What is natural selection?It is a process by which living organisms evolve.
The natural selection theory was proposed by Darwin. It states that organisms with traits that enable them to adapt better to the environment survive better and contribute more to the future population.
In the process of reproduction, the adaptive traits are passed to future generations. Thus, the future generation would be made up of individuals with adaptive traits.
Weak individuals without the adaptive traits gradually fade off from the population.

The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.
Meaning of speciationSpeciation can be defined as a process that births new species with different traits while they evolve.
Speciation occurs when extinction is eminent and most time in other to preserve that race they evolve into something new with new traits.

Explain how the process of natural selection can account for
the increase in frequency of the antifreeze protein gene in the
icefish population.
The antifreeze molecules allow icefish to live in subfreezing water by filling voids in existing small ice crystals and preventing the annexe of more ice molecules. Ice crystal development is thus effectively prevented.
Where are antifreeze proteins found?Antifreeze proteins (AFPs) are natural antifreeze components initially seen in polar fish; AFPs can attach to ice and thereafter inhibit the development of the ice crystals. Fish can inhabit (−0.7 °C) of their blood serum by the integrity of AFPs.
Thus, this could be the answer.

The concepts of genetic recombination, the production of more offspring, and surviving the challenges of the environment are associated with natural selection.
Natural selection and evolutionNatural selection describes the adaptation and modification of populations of living things.
Members of a population are inherently varied, which means they differ in certain respects. Because of these differences, some individuals can be better suited for their surroundings, which is very important in enhancing the chances of surviving and increasing the chances of reproducing as well, thus passing on their adaptive features to their progeny. These beneficial features grow increasingly prevalent in the population over time.
The differences in traits can be explained by changes in the structure of the molecules that make up genes (DNA) are known as mutations. Mutations can occur at random (for example, when replicating cells make a mistake while duplicating DNA) or as a result of exposure to toxic substances or radiation in the environment.
Mutations can be damaging, neutral, or even beneficial, leading to the development of a new, beneficial characteristic. Mutations can be handed on to children when they arise in germ cells.
These processes are all important for the evolution of species.

Classify the enzyme inhibitors by giving the names, mechanisms, and effect on the kinetic parameters Km and Vmax.
Enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.
What are enzyme inhibitors?Enzyme inhibitors are substances which inhibit the catalytic activity of enzymes.
Enzyme inhibitors are classified into three:
Competitive inhibitors - compete with substrate for enzyme binding site. They have no effect on Vmax but increases Km.Uncompetitive inhibitors- bind to the enzyme–substrate complex. They decrease both Vmax and Km.Non-competitive inhibitors- bind to another site on the enzyme. They have no effect on Km but Vmax is decreased.Therefore, the enzyme inhibitors are either competitive, uncompetitive or non-competitive inhibitors and have different effects on Km and Vmax.

(a) a prevailing wind coming from the North Pole
(b) a prevailing wind coming from the ocean
A prevailing wind coming from the North Pole would each type of prevailing wind have on the land it crosses.
What are the three different kinds of prevailing winds?
The trade winds, prevailing westerlies, and polar easterlies are the three predominant wind belts connected with these cells.
Although prevailing winds frequently come from the north sea and provide moisture to the land, they can also bring moisture to the land. There is no moisture or water involved when wind comes from a land location. This means that the winds bring more dry air into the atmosphere, reducing the likelihood of rain.

4. Based on the wintertime La Niña weather map, what do you think Florida's temperature and precipitation would be like during a winter El Niño event?
If the La Nina occurs, the Jetstream will be further north during the event. This has to do with the chilly temperature in the Great Lakes.
What is La Nina?Strong winds carry warm water towards Asia during La Nia episodes, causing upwelling along the west coast of the Americas. This means that in the Pacific, cold, nutrient-rich water rises to the top, pushing the jet stream northward.
In the winter, La Nina is associated with drier and warmer weather, which shifts to snowstorms in a northerly direction.
The lower southern region will have drier circumstances, while Florida will experience warmer than normal temperatures. As a result, Florida's winters will be moderate, with temperatures ranging from 5 to 18 degrees Celsius.
As a result, it will not experience the same conditions as the winter El Nino.
