Would you expect to see more biodiversity among members of a phyla or among members of a class? why?

2 answers:

7 0

A phylum has more biodiversity because class is what narrows the phyla down even more. ( The order of largest biodiversity to smallest biodiversity is domain, kingdom, phylum, class, order, genus, species)

Answer: Phylum

Explanation:

The phylum would have more number of species as compared to that of class. This is because according to classification phylum is bigger than class.

This means that many many different classes can come under phylum but a phyla cannot come under class.

So, the phylum has diversity of organism in it. At hierarchical level the organism belonging to phylum are at higher level and organism belonging to class are at lower levels.

What role does oxygen play in a plants life?

aleksandrvk [35]

Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.

Anton [14]

Answer: blood calcium level

Explanation:

There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity

, systemic blood pressure, and renal artery/arteriole diameters.

Filtration membrane integrity

: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.

Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.

Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.

Blood calcium level do not have any role in the kidney filterate formation or renal regulation.

Hence, the correct option is blood calcium level.
