Answer:
DNA sequencing can <u>decode numerous genes simultaneously, which enables scientists to determine which genes are related to diseases</u>.
Explanation:
Genetic disorders and diseases occur because of <u>changes that occur in an individual's genome. These changes alterate the normal sequence and lead to an abnormality or abnormalities in the DNA. </u>
Scientists use DNA sequencing to determine which portions of an individual's DNA contain specific genes. This technique is extremely important in life sciences as it is also used to identify potential genetic risk for these disorders.
For example, DNA methylation highly affects the transcription of genes. As DNA sequencing <u>can detect these modifications</u>, enabling scientists to uncover which genes are related to disorders. Moreover, this technique can <u>decode numerous genes simultaneously, enabling scientists to determine which genes are related to diseases</u>. By knowing this crucial information, they can switch genes off through other genetic techniques.
Answer:
The correct option is B) send chemical messages across small gaps between neurons.
Explanation:
Neurons are the cells that make up our nervous system. Although they are connected to each other, they do not maintain physical contact with each other. The nerve impulse travels through the neuron, and when it reaches its dendrites, it is transmitted to the next neuron through the synapse, which is produced through the exchange of chemical substances called neurotransmitters. Neurons communicate with each other through the small spaces (or small gaps) between them, in a process known as synaptic transmission (where synapses are the connections between neurons). This synapse requires neurotransmitters (for example dopamine or glutamate) for the transmission of the signal or message, which after being released will bind to specific receptors causing an ionic change by opening or closing a channel.
<span> ADP and ATP move pretty much in a cycle. ADP is converted to ATP by the weak bond formed between the ADP molecule and a third phosphate group. ATP moves to ADP by the removal of that weakly bonded phosphate group. </span>
