Answer:
The cell membrane is semi-permeable. It allows some molecules to enter easily inside the cell whereas some molecules are blocked from entering the cell.
Small, polar molecules and hydrophobic molecules enter easily through the cell membrane. But large molecules and ions cannot easily move inside the cell membrane.
A hydrophilic substance like the substance L mentioned in the question enters the cell membrane through the help of carrier proteins. The substance attached to the large protein might enter through active or passive diffusion but it can only enter the cell by attaching to carrier proteins.
Answer: Sudden loss of habitat
Explanation:
Endangered species are animal or plant species that are in danger of going extinct.
This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.

Answer:
O type blood (ii) and AB type Blood (IAIB) 50% of their children will have type A blood (IAi) and 50% will have type B blood (IBi)
Explanation:
Answer:
The best way to determine if these populations form part of the same species is to study the existence of reproductive isolation between populations. Moreover, the result of an experiment based on the study of reproductive barriers may be complemented with molecular biology approaches that determine the level of sequence homology between populations
