Describe how energy and matter move through the environment under both aerobic and anaerobic conditions.
elixir [45]

<span>1.    </span>Describe how energy and matter move through the environment under <span>
A. Aerobic conditions -Photosynthesis and Respiration
-After photosynthesis occurs, the plant enters the carbon cycle. The carbon cycle uses the by-product of photosynthesis which is carbon dioxide. Carbon dioxide combined with water yields glucose (used as food) and oxygen that is released back into the atmosphere. During photosynthesis, respiration occurs which uses the oxygen and glucose to yield carbon dioxide and water which starts the carbon cycle.

B. Anaerobic conditions Muscle respiration 
-This process does not require the use of oxygen.
Glucose stored in the body is used during muscle respiration to produce lactic acid and energy that is used for movement. </span>

<span>2.    </span><span> What is chemosynthesis?</span><span>
<span>- Chemosynthesis relies on chemical reactions to produce food. Inorganic compounds such as hydrogen sulfide, carbon dioxide, and oxygen enter into a chemical reaction that yields sugar, sulfur, and water, Chemosynthesis occurs most commonly in deep-sea ecosystems where the sun cannot penetrate. </span></span>

<span>3.    </span>How do chemosynthetic organisms get energy?

<span>-      </span><span>Chemosynthetic organisms make use of chemicals found on the seafloor or on the sea environment. They convert these chemicals through a reaction that yields glucose (which the plants use for food) and sulfur as by-products. In turn, other organisms will use the sulfur by-product to initiate another chemosynthetic reaction to create food.</span>

If a battery produced 12.6 volts, what would the current flow be for a 6 Ohm resistor
Free_Kalibri [48]

Answer:

I = 2.1 A

Explanation:

This is physics, but I will answer here either way.

First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:

V = R * I   (1)

This is the Ohm's law. From here we can solve for I and:

I = V/R   (2)

Now, we just need to replace the data and solve for the current:

I = 12.6 / 6

<h2>I = 2.1 A</h2>

Hope this helps

Which sentence is correct? All cells have the same genes, but different genes are active in different cells. Lungs look differen
mihalych1998 [28]

<u>Answer:</u>

All cells have same genes, but different genes are active in different cells

<u>Explanation:</u>

       Most living organisms are made up of different kinds of cells specialize in performing various functions like nerve cells perform different functions than blood cells. But all the cells are composed of same set of genetic information.

Since biochemical function is found out mainly by some specific enzymes, different sets of genes must be turned on and off in the various cell types to perform different functions. This is how cells differentiate for different functional capabilities.
