We are the chemical messengers that cross the synaptic gaps between neurons. when released by the sending neuron, we travel acro

ss the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse. answer 1 we are natural, opiatelike neurotransmitters linked to pain control and pleasure

Two petri dishes of radish seeds are prepared as follows: a disk of absorbent, but otherwise inert, filter paper is placed in th
valina [46]
A. The increased biomass in the sunlit dish came from the carbon and oxygen atoms present in the carbon dioxide it took up during photosynthesis that it used to synthesize organic molecules.

Plants use photosynthesis in order to convert light energy (from the sun) into chemical energy, stored in carbohydrate molecules (such as sugars). This chemical energy can be further transformed to fuel some of the organism's activities. This chemical reaction (photosynthesis) is light-dependent and includes the use of carbon dioxide and water to produce sugars and oxygen. The seeds that were put on a sunny windowsill had plenty of light energy needed for their photosynthetic activity. This resulted in the accumulation of sugar molecules in the plant tissues and an increase in the biomass. These sugar molecules were synthesized by the carbon and oxygen atoms comprising the carbon dioxide molecules absorbed during photosynthesis.   


B. The most likely explanation for the why the dark-grown seedling lost biomass is that cellular respiration in the cells of the seedlings consumed the starch and oils present in the seed as sources of energy.

Plants use cellular respiration in order to constantly supply energy to their cells. This chemical reaction uses the sugar molecules produced by the photosynthesis and stored in the plant tissues to get energy. Seeds put in a dark cupboard did not have access to any light energy, therefore, they could not perform photosynthesis. As a result, they had to perform respiration and consume starch and oils which were present in the seed to get the necessary energy. This resulted in a reduction in their biomass.

What is a possible consequence of increased ocean temperatures due to global warming? Mark all that apply.
dsp73

Answer:

Coral reef bleaching

Explanation:

<em>The correct answer would be coral bleaching.</em>

Coral bleaching is generally define as the change in color that results from the expulsion of green symbiotic algae from the tissues of the coral.

The expulsion of symbiotic algae from the tissue of coral is usually caused by a change in stressor factors of ocean water such as light, temperature, nutrient.

<u>When the temperature of ocean water increases as a result of global warming, the vibrant color of corals may be lost because the change in stress condition usually leads to the degradation of the algal pigments or outright expulsion of the symbiotic algae from the tissue of the corals. When this happens, it leaves the coral tissues completely white and they are said to have been bleached.</u>
