Answer:

The most correct option is carbohydrates & lipids

Explanation:

Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen [for example starch, (C₆H₁₀O₅)ₙ] while lipids generally contains carbon, hydrogen and oxygen [for example fatty acid, CH₃(CH₂)ₙCOOH] but could also contain other elements like sulphur and phosphorus.

Proteins are made up of building blocks called amino acids. Amino acids are made up of an amino group which consist of nitrogen and hydrogen. Hence, <em>proteins have a large number of nitrogen atoms thus not part of the answer.</em>

<em>Nucleic acids are composed of nitrogenous bases and phosphate groups and are also not part of the answer for this reason.</em>

Which scenario would most likely result in cooperative hunting?
ehidna [41]

Answer:

C. Wolves eat rabbits, and the number of rabbits in an area is low.

Explanation:

Cooperative hunting is a form of animal social behavior that is found common among predators mostly faced with a challenge of effectively finding prey to prey on easily. It involves the cooperation of a group of an animal species that cooperate together to effectively increase their chances of catching preys as well as increase their survival chances in such territories.

A scenario that would most likely result into cooperative hunting is where there are few and limited number of rabbits in an area, and as such, it is difficult to hunt rabbits due to scarcity. In order to increase their chances of catching rabbits, wolves in that area would cooperate together and hunt in packs. This will increase the number of kills they'd make when compared to hunting individually. This ensures there is availability of food to eat and also ensures their survival as a group.

How does blood help maintain the homeostasis in the body?
Ksivusya [100]

Answer:

Blood absorbs and distributes heat throughout the body. It helps to maintain homeostasis through the release or conservation of warmth. Blood vessels expand and contract when they react to outside organisms, such as bacteria, and to internal hormone and chemical changes.

Your heart pumps blood at variable rates depending on your degree of physical activity or neural/hormonal activity (this is call
GaryK [48]

Answer:

Explained

Explanation:

No, Homeostatic regulation requires Three components namely, a receptor, a control center and an effector. Without a receptor, there cannot be homeostatic regulation. Even though it seems that heart rate varies and returns to some number, this is not technically homeostatic regulation.  Blood pressure is homeostatically regulated - it has baroreceptors that monitor pressure, the brainstem that receives the information and nerves that then activate blood vessels to constrict or dilate to correct pressure (as well as other effectors) - but heart rate is not. Heart rate is not monitored by any neuron. Absolute water content of the body is not homeostatically regulated either - no neuron detects the number of water molecules, although neurons do detect the relative saltiness of the body.
