Answer:
Theory
Explanation:
It is a substantiated explanation because of the set of facts and observations on the experiment.
<span>It began with selective breeding in the ancient times where a population with desirable traits were bred with other population to achieve a desired set of traits. It then continued with the advance in the discovery of bacteria (Escherichia coli) and antibiotics. Then Watson and Crick discovered the structure of DNA. The latest advance being that of gene sequencing and gene editing tools. </span>
Answer:
B
Explanation:
Neurotransmitters such as acetylcholine, epinephrine are important at a neuron-neuron junction called synapses. When an impulse reaches the end of one neuron, at the synapse, it causes the release of neurotransmitters from synaptic vesicle that diffuse across the synapse and when they bind to their reports on the other end. An impulse is then generated on the subsequent neuron that travels down the axon to the next synapse.
Answer:
they generate heat, which is then used to make steam, which drives turbines that generate electricity.
Explanation:
Answer:
If the salts are not filtered from the transpiration stream, they can damage the plant.
If excluded by the root, the salts can make it harder for the root to extract water from the soil.
Explanation:
When soil has high salt concentration, it becomes very difficult for the plant to take in water. Sometimes the problem becomes so peculiar that plant becomes completely unable to take in the water and hence they wilt and die. This happens even when the surrounding soil has sufficient water but remains un-drawn by the plants due to its high osmotic potential resulting due to highly concentrated salt solution. Therefore, more energy and effort is required by roots to extract water from salty sand.
Also if the salt concentration with in the plant increases, it remains there and causes damage
Hence, correct options are
If the salts are not filtered from the transpiration stream, they can damage the plant.
If excluded by the root, the salts can make it harder for the root to extract water from the soil.
