Answer:
A. All of these choices are correct.
Explanation:
In pharmacology , drugs play different roles from simple to complex.
as is the above mentioned question drugs can facilitate the transmission of information from one neuron to another so option B is correct.
While the drugs / chemicals can inhibit the transmission of information from neuron to another so option C is also correct.
And the drugs can also be used to cure a whole variety of clinical disorders by playing a role at the synaptic level.
Hence option A All of these choices are correct is the right answer.
Answer:
water is technically mater and matter is involved in the water cycle to get it the way it is
he carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. Carbon is an element, something that cannot be broken down into a simpler substance. Other examples of elements are oxygen, nitrogen, calcium, iron, and hydrogen. Carbon compounds are present in living things like plants and animals and in nonliving things like rocks and soil. Carbon compounds can exist as solids (such as diamonds or coal), liquids (such as crude oil), or gases (such as carbon dioxide). Carbon is often referred to as the "building block of life" because living things are based on carbon and carbon compounds.
The Carbon CycleSource: NASAClick to enlarge
The amount of carbon on the earth and in Earth's atmosphere is fixed, but that fixed amount of carbon is dynamic, always changing into different carbon compounds and moving between living and nonliving things. Carbon is released to the atmosphere from what are called "carbon sources" and stored in plants, animals, rocks, and water in what are called "carbon sinks." This process occurs in a number of steps. In the first step, through photosynthesis (the process by which plants capture the sun's energy and use it to grow), plants take carbon dioxide out of the atmosphere and release oxygen. The carbon dioxide is converted into carbon compounds that make up the body of the plant, which are stored in both the aboveground parts of the plants (shoots and leaves), and the belowground parts (roots). In the next step, animals eat the plants, breath in the oxygen, and exhale carbon dioxide. The carbon dioxide created by animals is then available for plants to use in photosynthesis. Carbon stored in plants that are not eaten by animals eventually decomposes after the plants die, and is either released into the atmosphere or stored in the soil.
Large quantities of carbon can be released to the atmosphere thr
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).
prophase is the first stage and it looks like all the chromatin condenses into chromosomes and the nucleus dissolves (there is no nucleus when you look at it)
