B, because that is in its chromosomes and dna, the others they get or figure out how to do it
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Answer
The 4 events that occur during amoeba are:-
- It sees the food particle.Then by pseudopodia (the finger like projections from amoeba) traps the food particle.
- The finger-like extensions of the cell surface fuse over the food particle forming a food vacuole.
- Inside the food vacuole, complex foods are broken down into simpler ones which then diffuse into the cytoplasm.
- The remaining undigested material is moved to the surface of the cell and thrown out. [Egestion].
Going back to naming and classifying all of the living organisms, let us take a look at what can be the difference between<span> a specie and </span>population<span>. ... It is defined as the organisms capable of sexual intercourse and producing offspring which are fertile and able to produce as well

Answer:
D) Because sticky ends can be temporarily held together by hydrogen bonding between the two strands.
Explanation:
Restriction enzymes cut the DNA at specific restriction sites and by the mechanism of action they can form two types of ends:
- sticky ends-single-stranded overhangs are formed
- blunt ends-without overhangs.
The main advantage of sticky ends (their overhangs) is that they can complementary bind to another overhand formed by the same restriction enzyme. So, for example in cloning, if the DNA of interest and plasmid vector are cut with the same restriction enzyme, that forms sticky ends, fragment of DNA will fit into a bacterial plasmid in one direction.
On the other hand, blunt ends can be inserted into vector in both directions: head-to-tail or tail-to-head.
