Answer:
Option A) Protein carrier
Explanation:
The carrier proteins are those proteins that are involved in transfer of substances from one side to other side through plasma membrane. These are present in chloroplast, mitochondria and nucleolus.
The lipid carriers increases the absorption and solubility. These allows the transfer of non-polar molecules. The lipid carriers are used in drug delivery systems. So, this is an incorrect option.
The Porin carriers are present in the membrane of the bacteria. It allows the passive diffusion of molecules due to its large size. It only allows movement of hydrophillic substances.
The Polar molecules and ions moves across the biological membrane with the help of protein carrier. Thus, option A is correct.
Answer:
Some Abiotic factors are water, soil, light, temperature. These are non-living things that the tortoises will interact with in the enviornment. These can affect them for example if there is an abundance of water and light then the tortoise population can expand. However if there is too little or too much of these factors then the population will decrease. Biotic factors are plants, animals, bacteria and Protists. These are the living things the tortoises will interact with in the enviornment. Biotic factors can affect them for example if there are too many preditor animals for the tortoises, then their population will be very low and a lot of them will die.
