They are the light reactions and calvin cycle. The products from light reactions are ATP and NADPH
An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
Answer:
1. Nerve impulse
2. Neurons
Explanation:
Neurotransmitters are compounds with low molecular weight. They are secreted by axon terminals of the neurons. The released neurotransmitters then bind to the receptors located on next neuron or on the surface of muscle cell.
The function of neurotransmitters is to carry the nerve impulse from presynaptic neuron to the postsynaptic neuron or from neurons to the effector organs such as muscles and glands.
For example, neurotransmitters are released into the synaptic cleft to transmit the nerve impulse between neurons.
A recent study of a model organism found that a specific HMG protein localized mainly to the ends of chromosomes. Given this result, the site of localization for this HMG protein would correspond to regions in humans that Contain heterochromatin similar to that of centromeres.
Telomeres are regions at chromosomal ends that are time and again truncated with every round of the cellular department. Centromeresjoin sister chromatids and are required for correct chromosome division for the duration of mitosis.
Notwithstanding their different chromosomal locations, each telomere and centromere are composed of heterochromatin, a tightly condensed complex of DNA wrapped around histones.
Due to its structurally restrictive form, heterochromatin is transcriptionally inactive, which means that proteins liable for regulating gene expression can't get entry into the tightly packed DNA. As an end result, hetechromatic regions are often gene-bad and incorporate repetitive DNA.
