1. Proteins
They are used by organisms for production of nucleic acids and repair damaged tissues. They can also be broken down to produce ATP during starvation.
2. Nitrogen
Nitrogen gas is abundant in the atmosphere but plants cannot directly absorb, they need nitrogen fixing bacteria to break it down into compounds (ammonia and nitrate) that plants can easily absorb for growth and chlorophyll build up.
3. Carbon dioxide
Used by plants to produce their own food (sugars) using energy from the sun and carbon dioxide from animals, releasing oxygen and water vapours i.e. photosynthesis.
Answer:
The plant on the left does not accumulate significant photochlorophyll or carotenoids, so it will become very pale on the shoot tip, while the plant on the right will continue to grow upward as auxin is uniformly distributed around the tip of the right plant.
Explanation:
Phototropism is the orientation of a plant in response to light, either towards the source of light or away from light. Positive phototropism is growth towards light, while negative phototropism is away from light.
Auxin are substances that promote and regulate the growth and development of plants. Auxin escapes light making the area in the shade elongate more so the plant tip moves towards the light.
When an antibiotic is given for a non- resistant bacteria it inactivates or kills the bacteria however some microbes do not die and survive and multiply and pass the infection to other people making the bacteria antibiotic resistant.
Explanation:
The antibiotic resistant bacteria are those that are able to resist the effect of antibiotic and renders them ineffective that was once able to kill or inactivate bacteria.
While antibiotic non-resistant bacteria are those that are not able to resist the effect of antibody.
The reason some non-resistant bacteria becomes resistant is that a mutation in the nonresistant bacteria may occur or continuous exposure of the antibiotic would make it resistant to it.
Every time an antibiotic is taken for some bacterial infection it kills the bacteria but some that survive become resistant and grow in numbers and get transfer to other people causing them to be antibiotic resistance. The infection transfer to other people would not be treated by once used antibiotic as the microbe has become resistant.
During the cell replication due to some mutation caused they get resistant to antibiotic by a process called selective pressure.
Photosynthesis contributes to plant growth by B. taking in carbon dioxide and making sugars (carbohydrates)
Geothermal energy maybe is their answer choices
