Answer:

They are organisms (individual organisms called "plankters") that live in large bodies of water.

7) Other than sunlight for energy, photosynthesis in plants needs these two things that we breathe

almond37 [142]

Answer:

Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive. However, plants also take in energy from the sun(light), carbon dioxide from the atmosphere, and water from the soil; they use all of them in order to make sugar, and release oxygen.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

hope it helps

For plants living in a dry areas, explain a possible conflict between the need to obtain carbon dioxide for photosynthesis and t

ahrayia [7]

Plants living in dry areas face conflict.

EXPLANATION:

Since they live in dry areas they will undergo more transpiration.

If they open stomata during the day there will be excessive loss of water vapor that will result in their death.

Therefore plants living in this area open the stomata during the night to obtain Carbon dioxide.

This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.

Lelu [443]

I think the correct answer from the choices listed above is option A. In plants, the purpose of auxins is to produce phytochrome. The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant. Hope this answers the question.
