DNA in Plants. DNA is the hereditary orgenetic material, present in all cells, that carries information for the structure and function of living things. In the plant kingdom, DNA, or deoxyribonucleic acid, is contained within the membrane-bound cellstructures of the nucleus, mitochondria, and chloroplasts.
The charge of the electrical impulses sent from stimuli is extremely positive. Thus, the correct option is A. The net charge of such electrical impulses is positive because of the positively charged ions of the Na+.
<h3>What is an electrical impulse?</h3>
An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.
In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.
Therefore, the correct option is A.

A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.
ExplanationThere are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts. the direction of flow of the air mass and its characteristics. so based on what we know i would say that warm fronts are calmest
