Answer:
A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.
Answer: Very unlikely
Explanation:
Generally, point mutation can be easily reversed by another point mutation, so
before any changes occur in the amino acid sequence, it would have been corrected.
However, when point mutation occurs within the protein coding region of a gene it may results in the change of a single nucleotide to cause the substitution of a different amino acid (which renders the protein non-functional) as in the case of sickle-cell disease.
And this kind of point mutation is specifically called Missense mutation.
Above all, because point mutation is easily reversible, it is very unlikely to change the amino acid sequence of a protein
1. The correct answer is B. Conservation tillage practices help the soil erosion and also maintains soil nutrient levels.
Conservation tillage is termed as the tillage system which helps to conserve energy, soil, water through retention of crop residue and reduction of tillage intensity.
2. Correct answer is A. Aquifers 1 and 3 may result in a reduced river flow. Aquifer is termed as the underground layer of rock fractures, water-bearing permeable rock.
Hydrogeology is termed as study of water flow which is found in aquifers.
3. Correct answer is A. Recycling materials helps decrease the amount of new material which are taken from environment.
Most household can be recycled. Some other examples which are recycled include textiles, plastics, organics, and metals. Metals such as drinking bottles and food cans which are made from steel and aluminium can be recycled.
The correct answer is option d. its absence would affect many organism present in the community.
The keystone species are the one, who play a very important role in the ecosystem. In case, the keystone species is wiped off from a particular ecosystem, then the function of the ecosystem would cease and lead to a major effect. Hence, the keystone species is very important for the survival of ecosystem.
