Answer:
c. There will be a net diffusion of oxygen from the water into the bloodstream only if the partial pressure of oxygen in the water is greater than 100 mm Hg
Explanation:
Diffusion involves the movement of molecules from the region of higher concentration to the region of lower concentration. If the molecules are gas molecules, they will diffuse from the region of higher pressure to the region of lower pressure.
Hence, for net diffusion to occur from the water to the bloodstream, the partial pressure of oxygen in water must be higher than the partial pressure of oxygen in the bloodstream.
<em>Since the partial pressure of oxygen in the bloodstream is 100 mm Hg, then the partial pressure of the gas in water must be more than 100 mm Hg in order for net diffusion to occur from water to the bloodstream.</em>
Answer:
The answer is D because the animal will eventually die
Explanation:
Answer:
somatic cells have highly specific functions
Explanation:
In our body, the major part of cells is irreversibly differentiated into somatic cells. From a cellular point of view, this process of differentiation seems to be an evolutionary disadvantage. However, cellular differentiation is a process aimed at exploiting the genetic variation in order to obtain a highly specialized cell type that is capable of carrying out a specific cellular function. For example, keratinocytes are highly specialized epithelial cells that function by separating the organism from the surrounding environment.
Because b appears to be an intrusion, the answer should be A.
It is the macroscopic anatomy with a systemic approach.
There are two levels of the human body: macroscopic (gross anatomy) and microscopic level. For each of the two levels, there is a separate subdivision of anatomy.
There are two approaches for gross anatomy:
1. Regional approach-human body is divided into regions like arm, forearm, wrist etc. Structures within that region are studied simultaneously.
<span>2. Systemic approach-the body is divided into organ systems like skeletal system, or nervous system and structures belonging to one system are studied together.</span>
