Dehydration is the cause of this weakness, in relation to cellular respiration because in cellular respiration water is produces when the glucose molecules are broken down for the release of energy. In this process, our body temperature increases so our body removes heat from the body with the use of water which leads to dehydration and the athlete feels hard and becomes dizzy and feels ill and weak.

The correct answer is C. There is abundant food and space.

Explanation

The graph shows the size of the rabbit population over time in an ascending curve in which point b is in the middle of the ascending line, so it can be inferred that at this stage the feeding conditions and space are abundant, allowing the population to continue to grow in this place. So the correct answer is C.

Answer:

O macromolecule, population, community, ecosystem

Explanation:

Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).

The correct option is  macromolecule, population, community, ecosystem

Answer: Savanna

Explanation:

The Savanna is a biome located in Africa and characterized by a lot of grass and dispersed trees. The climatic conditions are warm all year round and the summers are wet.

The presence of so much vegetation makes it an ideal biome for large herbivores like elephants, giraffes and wildebeests. As a result of so many herbivores being there, there are lots of carnivores as well such as lions and cheetahs.

╭☞ If you wanted to study large, migratory grazing animals like wildebeest, which biome would you chose to visit?

╭☞ Savanna or Savannah

Explanation:

╭☞ Because Savanna or savannah, is a migratory grazing animals like wildebeest and type of plant that grows under hot, seasonal climatic conditions and is characterized by an open tree trunk (i.e., scattered trees) above a continuous- continuous tall grass understory (the layer of vegetation between the canopy of the forest and the ground).

This question lacks options, options are:

A) family affect  

B) family strengths  

C) family process  

D) family organization.  

The correct answer is D.

Explanation:

The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.
