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.

Which of the following is not a direct fate of the energy flowing through photosynthesis? a. carnivores b. cellular respiration
EastWind [94]

Answer:

The correct answer is a. carnivores.

Photosynthesis is the process by which plants make their food from carbon dioxide and water in the presence of sunlight and chlorophyll. Hence, they convert light energy into chemical energy (food or glucose).

This energy is first utilized in the cellular respiration and then the rest in transferred to the primary consumers i.e. herbivores which feed on green plants.

They use this energy in their metabolic processes. The rest is transferred to the secondary consumers i.e. carnivores which feed on the herbivores.

Hence, energy from the photosynthesis indirectly passes to the carnivores via herbivores.

A race car drives one lap around a race track that is 500 meters in length. What is the driver's displacement at the end of the
Temka [501]

Answer:

zero

Explanation:

Displacement is a vector, meaning that the direction is  very important. Displacement is the distance from the starting point to wherever the object is. So a car that does a 500 m lap will have covered 500 m in distance but displacement is zero because, having come back to the starting point, the distance between the starting point and where the object is, is zero.

Check Your Understanding<br> Question: What is an adaptation?
AleksandrR [38]

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.

Meteorologists take careful measurements of daily minimum temperatures, maximum temperatures, and precipitation (rainfall). The
Vinil7 [7]

Months with higher temperature have more rainfall.

Explanation:

From the presented graph, we can see that all three parameters are following a same trend. When the maximum temperatures increase, the minimum temperatures increase too, and the rainfall increases as well. When the maximum temperatures decrease, the minimum temperatures decrease, and the rainfall decreases too.

There is a simple explanation for the connection of higher temperature and more rainfall in Scotland. Scotland is located on an island, thus it is heavily influenced by the sea. When the temperature is higher, the humidity is higher, and in accordance to that more rainfall occurs. When the temperature is lower, the humidity is lower, so there is less rainfall, or instead of rainfall the precipitation can be manifested as snowfall.
