Answer:

​A protein needed for blood clot formation.

Explanation:

Prothrombin may be defined as the protein that changes in to the thrombin during the process of blood coagulation with the help of clotting factor X.

The main function of the prothrombin protein is the coagulation of blood. This protein is responsible for blood clotting at the time of external and internal injury.

Thus, the correct answer is option (c).

HI~ I hope this helps

(these answers were hand-written meaning I did not copy and paste so, feel free to use the answers freely)

1.

When ecosystems change rapidly the fundamental environmental cycles such as the circulation of water, carbon and nutrients can change as ecosystems depend on them. The usage of factors such as freshwater, carbon dioxide emissions and fertilizer provides a large benefit to humas therefore meaning, that large and rapid changes to an ecosystem could also effect the things we as humans rely on.

2.  

Complex organic matter is broken down by decomposers into carbon dioxide, water etc. The ecosystem is affected based upon the fact that the decomposition of organic matter that is produced by plants, animals and soil organisms is an important process which affects the different important ecosystem processes like nutrient cycling and carbon sequestration.

3. (could have two answers- I recommend the second)

Adaptation- due to the mutation process which results in changes in the structure and function of organisms, these ecosystems would be different as well as unique. The organisms which possesses the traits needed to adapt could then survive as its unique characteristics due to mutation would provide a strong ability

Rise in temperature- If the temperature located on earth was to rise, organisms would have a higher living rate as bacterial life flourishes in warmer temperatures and dies out in colder ones.

4.

~The rapid change of increased food production provides better life sustainability to those living in the ecosystem.

~The rapid change in a large increasing number of organisms could be helpful as they often live of off one another.

5.

~Rapid growth of things such as phytoplankton which cause dead zones are harmful to the ecosystem. Dead zones create zones where too much oxygen is consumed resulting in areas where plants and sea life can no longer survive.

~Whereas the rapid increase of organisms could also be harmful to an ecosystem as the possibility of the organism outnumbering the food sources could become prominent.

Why can a wolf be considered both a secondary consumer and a tertiary consumer
In-s [12.5K]

Answer:

A wolf can be considered as both a secondary and primary consumer because they feed on both primary and primary and secondary consumers. As a secondary consumer, wolves can feed on plant eaters [primary consumers] such as elk which is an herbivore. As a tertiary consumer, wolf feed on secondary consumers such as deer.

Describe the strength of the magnetic field at points a b and c in the image below. Explain your answers in the terms of magneti
Nastasia [14]

The magnetic fields are strongest at point A and weakest at point C. The magnetic field lines can be used to indicate the strength of a magnet or magnetic field. The closer together the magnetic field lines the stronger the magnetic field.

Explanation:

The magnetic field line also shows the direction of the magnetic field, hence they are also considered vector fields because they have magnitude and direction. They usually have an arrow indicating that the field lines are moving from the north pole to the south pole. The lines also never cross and are always in closed loops.

PLEASE HELP<br> ME PLEASE

Whales are closely related to hoofed mammals with an even number of toes, such as horse, because they evolved from them. Before whales were what we know them as today, they were relatively similar to horses. They used the water to flee from predators, and they evolved slowly to heighten their swimming ability, eventually becoming modern day whales. Fish have always been aquatic animals that have gills. Whales cannot breathe underwater, so they take in oxygen the same way a horse does. Also, both horses and whales are mammals that give birth to their offspring and are warm-blooded. Fish lay eggs and are cold-blooded.

Hope this helped! Please give brainliest! :)
