Answer: B.) More research is needed to reach a conclusion, including related variables
Explanation:
As it is evident that oxygen is necessary element for living beings. It is required for the process of respiration, in which the food particles are broken down in the presence of oxygen into simpler substances.
Applying this knowledge to the given study suggests that all organisms require oxygen which can be less or more depending upon their habitat either in the shallow waters or in the depths. This conclusion is invalid and requires more explanatory approach which can be achieved by more research so as to derive a valid conclusion in which the two variables oxygen and relative habitats can be compared.
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.
It's not alive, nor is it even an organic compound.
- It cannot respond to stimuli (Responsiveness)
- It cannot secrete hormones (Secretion)
- It cannot send messages along a nervous system or anything similar (Conductivity)
- It cannot break down compounds to usable energy forms (Digestion)
- It cannot absorb broken down compounds as an energy source (Absorption)
- It cannot reproduce (Reproduction)
- It cannot grow--it has no cells (Growth)
- It cannot exchange gases between cells (Respiration)
- It cannot rid itself of waste material (Excretion)
Answer:
The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation
Answer:
Chicken eggs grow larger compared to other eggs due to their relative body sizes.
Explanation:
Egg laying and the size of an egg is relative to the size of the organism. So an ostrich lays a really large egg because it is a larger animal and can handle that size. Whereas a bluebird lays a small egg because it is a small bird.
