Answer:
Grass -Grasshopper - Frog - Phyton - Eagle
It has very thick fur or hide so it cant be stung by bees's, except for its nose. Also its very resistant to Poison from snakes and scorpions. That would be my answer out of these 2 <span />
Answer:
Explanation:
In the structure of Nucleic acids the nucleobases (nucleotide and bases) are arranged is a specific form.This form of arrangement is called Base stacking.It simply refers to the bond formed between the adjacent bases.
These nitrogenous bases of (A,T,C.G) pairing in DNA are in planes in geometry.The bases planes stack with one another.This form of arrangement give rooms for more Van der Waals interactions in the plane of the bases.Although the Van der Waals are weak interactions,the bond ensure that these bases are braided or twisted together to give maximum energy,to maintain stability of the bases,and therefore of DNA structure
Therefore in water and other aqueous solution the stability of structure of DNA is enhanced by the base stacking,(coiling or twisting)with maximum van der waals interaction among the bases, than the hydrogen bonds formed between bases.Generally there are more stacking among G-C,than A-T,thus the former pairing contribute more the structural stability than the latter (A-T)
Answer:
availability of resources.
Explanation:
Availability of resources is abiotic factor which is responsible for the decrease in population in 1990 because when the population reaches its carrying capacity so the organisms compete with each other and due to limited resources such as food etc the decrease occurs in population. Infection is also occurs when there is high population due to which death occurs and population of organism decreases.
Okay so northern Africa and the Sahara desert is the best example of desertification.
2 ways humans have contributed to that is: 1) pastoral nomadism 2) little to no settlements to increase water supply
how it impacted the environment: so now the environment there is sandy, only organisms adapted for those extreme environment can live there ex. camel, cactus, etc.,
how it impacted quality of life: quality of life diminished, not enough water to sufficiently feed the populations, people live in extreme poverty, people are moving away, and the climate is very dry and hot, pretty much not a place anyone would want to live
