Answer:
The correct answer is amino acids.
Explanation:
The organic compounds, which associates together to produce proteins are known as amino acids. The proteins and amino acids are the building blocks of life. At the time of the digestion or dissociation of proteins, amino acids get left. A huge ratio of the muscles, cells, and the tissues are formed of amino acids, which shows that they conduct various essential functions of the body like providing cells their composition.
Answer: E. all of the above.
Explanation: for human infants to grow and develop normally, the need for them to interact with people (family, friends and the public) cannot be over emphasized. Interaction with people goes a long way in the brain, physical and social development of infants.
Frequent interaction with people helps infants in their communication skills.
Answer:
1. Brain
2. Peripheral nerves
Explanation:
The nervous tissue or the nervous system is a system in the humans or animals formed by the neurons.
The nervous system can be categorised into two types based on the structure and functions: the peripheral nervous system and the central nervous system.
The central system of neurons comprises of the neurons present in the spinal cord and the brain and the peripheral system which comprises the nerves of the organs present except the brain and the spinal cord like the nerves in the limbs (legs, arms).
Thus, Brain and Peripheral nerves are correct.
The correct answer is D. None of the above
Explanation:
Urban sprawl or the expansion of human settlements such as cities has multiple negative consequences on the ecosystems. This includes deforestation because trees are usually cut to build houses and other human structures. Indeed, most threes and plants are removed for human construction. This also implies a loss of natural resources that include a wide variety of plants, animals, and even water as nearby bodies of water might be polluted. Besides, this general pollution increases in the area this includes noise pollution, water pollution and air pollution that result from human activities. Thus, all are possible consequences of urban sprawl; therefore, the correct answer is none of the above.
Answer:
Substitution Mutation
Explanation:
It can’t be deletion or addition as the base pairs of DNA haven’t shifted to the right or left.
If they had the second sequence would have an extra/one less base pair which isn’t the case.
It can’t be an inversion, as that’s where the base pairs from the opposite DNA strands are inverted/switched.
If it was inversion, you would have had a C instead of an A for Sample 2.
This is due to complementary base pairing where guanine bind with cytosine and adenine binds with thymine.
Therefore, this only leaves substitution as a viable answer.
