The correct statements are I, III and IV.
An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.
Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.

Aquaporins would be expected to increase in numbers when there is an insufficient amount of water present in the blood.
Aquaporins are a type of proteins which are present in the integral membrane of the cells. They act as channels and help in the transport of water and small solutes across the membrane.
Whenever there is insufficient amount of water present in the blood, the antidiuretic hormone or the ADH responds. The aquaporins increase in number in the blood. They allow the transcellular reabsorption of water. Due to this fact, more water is able to escape from the collecting tubules and enter the blood.

The pyramid of biomass represents a range of food webs found in one trophic level
A pyramid of biomass refers to graphical representation of biomass that is present per unit area of all the various trophic levels of the ecosystem.
<h2>Further Explanation</h2>
The graphical representation shows the relationship between biomass and trophic level that quantify the biomass that is present in each trophic level of energy community at a given period of time.
There are two types of pyramid of biomass, they include
- Inverted pyramid of biomass
- The upright pyramid of biomass
Inverted pyramid of biomass: a very good example of inverted pyramid can be seen in a case of pond ecosystem, where major producers in the ecosystem (mass of phytoplankton) will be lower than the mass of heterotrophs, such as insects.
The upright pyramid: The first thing on the upright pyramid is the producers, such as plants. The plants are present at the bottom level of the pyramid and followed by consumers.
Within the pyramid, the highest level is occupied by the carnivores; they are the lowest quantified amount of biomass. In upright pyramid the total weight of the producers is far more than when the weights of all the consumers are combined.
However, the main issues with the pyramid of biomass are that every trophic level of the pyramid seems to have more energy than it does.
