Answer: Exploitation, invasive species
If the government introduces laws prohibiting hunting, it would somewhat reduce the impact of exploitation would have on the biodiversity because hunting is mainly done for the purpose of fun or to derive valuables from animals like skin, horn, ivory, venome for selling them in the international market and making huge profit from them. Introduction of prohibition law on hunting will reduce killing and exploitation of animals for their valuables.
If laws prohibiting introduction of new plant or animal species within the country are passed, it will curb the effect of invasive species would have on the seas. Invasive species are those living species which are arrive or immegrate to new locations in search of resources. These species compete with native species which results in decline of native species. This will result in disturbance in actual sea biodiversity as this will result in decline in native sea species and may also lead to extinction of native species.
It's because of hydrogen bonding among water molecules
Answer:
A) The pollen grains will be pure red.
Explanation:
Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).
In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte). When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.
Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.
Answer: D. Heat
Explanation : Water Vapor is a source of warmth, since the heat that is radiated from Earth is absorbed by the water vapor. This is why greenhouses use water vapor as well.
