The answer is c ) cellular respiration uses oxygen and releases carbon dioxide while photosynthesis uses carbon dioxide and releases oxygen
Answer:
The correct answer is - regulation of the heavy metal and their toxicity.
Explanation:
Metallothionein is a group of cysteine-rich, small in size, and highly conserved proteins that bind to various metal ions and regulate their activity or toxicity in transcriptional level.
Metallothionein IIA is one of the metallothioneins that binds to heavy metal and helps cells to be protected from the toxicity of these heavy metals. These proteins are present in almost every eukaryotic organisms virtually. These proteins are highly induced to express highly in the present of heavy metals.
Thus, the correct answer is - regulation of the heavy metal and their toxicity.
Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
<h3>What are the effects of irrigation agriculture on river basins?</h3>
Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

According to the starling law, parasympathetic effects on cardiac rate and contractility include decreasing the rate of contraction and increasing the filling time resulting in a stronger contraction.
The Frank-starling law of the heart states that the stroke volume of the heart increases in response to an increase in the volume of blood filling the heart when all other factors remain constant.
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
