ololo11 [35]
The relationship between the size of individual organisms and the number of organisms in a given trophic level is D) inversely proportional. 
This is because a larger organism must consume more in order to sustain itself. Therefore, there can either be more organisms of smaller size or less organisms with larger size, because the energy entering a given trophic level is limited.
This is also the basis of formation of biomass pyramids, the total mass at higher trophic levels decreases.

Answer:

Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.

Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.

-How do you think andioxidants can help cells perform their functions? -Why do plants have more antioxidants than humans? -Do yo
Vsevolod [243]

Answer:

Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.

I hope this helped you!
