How does photosynthesis benefit heterotrophs
- A.
It adds carbon dioxide to the air
- B.
It creates food that they can eat
- C.
It creates clean water
Correct Answer
B. It creates food that they can eatExplanation
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Heterotrophs, such as animals and humans, cannot produce their own food and rely on consuming other organisms for energy. Therefore, photosynthesis benefits heterotrophs by producing food (glucose) that they can consume and obtain energy from. This process forms the foundation of the food chain, providing nourishment for all heterotrophic organisms.Rate this question:

Photosynthesis and respiration form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because photosynthesis and respiration do not form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere. While photosynthesis removes carbon dioxide from the atmosphere and releases oxygen, respiration does the opposite by consuming oxygen and releasing carbon dioxide. This creates a balance between the two processes, but it does not keep the levels of water and carbon dioxide constant in the atmosphere. Other factors such as human activities and natural processes also influence the levels of these gases in the atmosphere.Rate this question:
-
- 16.
Photosynthesis and respiration form a cycle that keeps the levels of __________ and carbon dioxide fairly constant in the atmosphere 1. oxygen 2.respiration 3. water
Correct Answer
oxygenExplanation
Photosynthesis is the process by which plants convert carbon dioxide and sunlight into oxygen and glucose. On the other hand, respiration is the process by which organisms release carbon dioxide and use oxygen to produce energy. These two processes are interconnected and form a cycle. During photosynthesis, plants produce oxygen and absorb carbon dioxide, while during respiration, organisms consume oxygen and release carbon dioxide. This cycle helps to maintain the levels of oxygen and carbon dioxide fairly constant in the atmosphere. Therefore, the correct answer is oxygen.Rate this question:

The raw materials for respiration are the opposite of the end products for photosynthesis
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the raw materials for respiration, which are glucose and oxygen, are also the raw materials for photosynthesis. In photosynthesis, glucose and oxygen are produced as end products, while in respiration, these same substances are used as raw materials to produce energy. Therefore, the raw materials for respiration and the end products for photosynthesis are not opposite, but rather the same.Rate this question:
-
- 18.
The raw materials for respiration are the _______________ the end products for photosynthesis 1.same of 2.different 3.opposite
Correct Answer
same ofExplanation
The correct answer is "same of". This means that the raw materials for respiration are the same as the end products for photosynthesis. This is because respiration and photosynthesis are interconnected processes in which plants use carbon dioxide and water to produce glucose and oxygen during photosynthesis, and then use glucose and oxygen to produce carbon dioxide and water during respiration. Therefore, the raw materials for respiration are the same substances that are produced as end products during photosynthesis.Rate this question:

When muscle cells run low on oxygen lactic acid fermentation take place
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When muscle cells run low on oxygen, lactic acid fermentation takes place. This is because during intense exercise or when there is insufficient oxygen supply, muscle cells switch from aerobic respiration to anaerobic respiration. In anaerobic respiration, glucose is broken down into lactic acid, which helps produce energy for the muscles. This process allows the muscles to continue functioning temporarily without oxygen, but it also leads to the accumulation of lactic acid, causing muscle fatigue and soreness. Therefore, the statement that lactic acid fermentation takes place when muscle cells run low on oxygen is true.Rate this question:

Small openings called______________________allow carbon dioxide to enter a leaf.
Correct Answer
stomataExplanation
Stomata are small openings found on the surface of leaves that allow gases, including carbon dioxide, to enter and exit the leaf. These openings are surrounded by specialized cells called guard cells, which can open and close the stomata to regulate gas exchange and prevent excessive water loss. Through the process of photosynthesis, carbon dioxide enters the leaf through the stomata and is used by the plant to produce glucose and oxygen. Therefore, stomata play a crucial role in the gas exchange and carbon dioxide uptake by plants.Rate this question:
