Which kind of aquatic ecosystem does the photograph most likely show?A. Marsh

B. Swamp

C. Lake

D. River

Answers

The correct answer is D. River

Explanation:

Rivers are one of the most common ecosystems. A river is characterized by flowing water in which biotic factors (animals, plants, bacteria, etc.) and abiotic factors (rocks, water, minerals) interact. Also, they cross major ecosystems such as forests or rainforests.

Moreover, rivers are unique because they contain fresh rather than salt water as in the ocean, and they are always flowing while in a marsh, swamp or lake the water does not flow. This suggests the ecosystem is the photograph is a river because in this the water flows and as a result of this, there is a strong current which is possible in a river but not in a lake, marsh or swamp.

Answer:

river

Explanation:

it is smaller than the width of a lake

Which statement best describes substance X?

RL is oxygen released by protein synthesis.
(2) It is glucose that was produced in
photosynthesis
(3) It is starch that was produced during digestion
(4) lis carbon dioxide released by respiration

Answers

Answer:

The correct option is D. It is carbon dioxide released by respiration.

Explanation:

The process by which ATP is abundantly formed in organisms is termed as cellular respiration. Cellular respiration can be described as a process in which carbon dioxide and water are produced from glucose and oxygen. ATP molecules are synthesized by this process which are used for cellular activities.

Hence, the substance X in the investigation shows carbon dioxide which was produced when the yeast cells began to respire. Yeast cells can respire either in the presence of oxygen or without oxygen.

John is trying to identify how strong his lungs are. In order to do so he finds out his TV is 450 ml, IRV is 2.6 L, ERV is 900 mL. What is his vital capacity

Answers

Answer:

Vital capacity can be defined as the maximum volume of air a person can breathe in after a forced expiration. It is equivalent to the sum of expiratory reserve volume (ERV), tidal volume (TV) and inspiratory reserve volume (IRV).

  • Expiratory reserve volume (ERV): It refers to the volume of air a person can exhale by forcible expiration or air exhaled from the end-expiratory position.
  • Tidal volume (TV): It is a volume of air inhaled or exhaled during a normal respiration.
  • Inspiratory reserve volume (IRV): Maximum volume of air a person can inhale from the end-respiratory position.

Now, the vital capacity of John would be =  450 + 2600 + 900 ml

= 3950 ml or 3.95 L.

Why do you never see the far side of the moon from Earth?

Answers

You can never see the far side of the moon from Earth because the moon is fixed in its orbit around the earth, meaning that one side is always facing Earth.
A common term for the side we can't see is "the dark side of the moon", but that designation isn't necessarily 100% accurate since the other side is lightened by the sun just as much as the side facing us.
Hope that helped! =)
