Energy flow within a system that contains life is necessary. Scientists have explored this idea in projects such as Biosphere 2

and conducted studies about the possibility of colonizing Mars. How might research on the flow of matter and energy through ecosystems be helpful to creating a colony on Mars?

Answer:

Energy flow is integral to any biological environment that supports life. Since energy can neither be created nor destroyed, it has to change from one form to another in order to maintain a balance. Everything within an ecosystem is interconnected, from plants as producers to herbivores that feed on the plants and the predators that feed on the herbivores. All of this will have to be established de novo at Mars using artificial means because the Mars atmosphere cannot naturally do this.

Hope that answers the question, have a great day!

How did fish fossil reach the surface
Andrei [34K]
Fish fossils occur in sediments deposited underwater. That could be sea bottom, lakes, or rivers. Generally, seabottom sediments are raised to the surface by tectonic uplift. Also, when sea level falls during ice ages, sea bottom sediments are exposed to the atmosphere.

REY [17]

Question is incomplete. Complete question is as follows:

You have decided to determine how many microbes are living on the lettuce in the salad bar at your favorite restaurant. You place 1 gram of lettuce and 99 mls of water in a blender and blend the mixture. This is sample A. You then transfer 1 ml of this dilution into to another that contains 9 mls of water. This becomes sample B. You next transfer 1 ml of sample B into a separate container that contains 9 mls of water. This is sample C. Next you transfer 1 ml each from samples B & C onto separate nutrient rich agar plates, swirl, let harden and incubate at 37C. When you examine the plates after 48 hours you find 110 colonies growing on plate C. How many microbes were living on that 1 gram of lettuce?

Answer:

1.1x10^6 microbes

Explanation:

When 1gm of lettuce is mixed with 99 ml of water, the microbe concentration is diluted 100 times (Sample A). 1 ml of sample A is mixed with 9ml of water to make sample B which further dilutes microbe concentration 10 times making the total dilution 1000 times. This process is repeated with sample B to make sample C increasing the dilution to 10000 times.

110 colonies are counted from this sample C. Each colony signifies a single microbe during plate counting method. So, 110 microbes were present on the plate. Original number of microbes = microbes counted * times of dilution =

110 * 10000 = 1100000 = 1.1x10^6 microbes

An important difference between cellular respiration and photosynthesis is that when cellular respiration begins, glucose molecu
sergey [27]
The answer is water molecules are split.

Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose and oxygen yield water and carbon dioxide. So, when respiration begins, glucose molecules are split. In the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. Thus, <span>when respiration begins, water molecules are split.</span>
