Tems11 [23]

Answer:

The star could also be said to be 360 Million Million miles from the earth's sun.

Explanation:

A light year equals 9.4607 × 10^{12} km.

This is also approximately 6 Million Million Miles.

If we expressed the answer in miles, then we have to multiply 6 by 60.

This is equals to 360.

Therefore, 60 Light years is approximately 360 Million Million miles.

Cheers!

DDT is an insecticide that was formerly used to control insects that would eat crops. It was banned from use in the 1970s.
Reil [10]
<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>

Explanation:

Let us understand the term DDT

DDT : Dichlorodiphenyltrichloroethane

  • This is a crystalline chemical compound
  • Basically used for protecting insects eating crops
  • It is colorless, odorless, tasteless
  • Initially used as pesticides

It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.

It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.

It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures

It contained toxins: It contains moderate toxins.

Emily has been asked to find out how
Juliette [100K]

She should investigate how temperature affects the rate of oxygen production.

<h3>Photosynthesis</h3>

During photosynthesis, green plants make use of inorganic products in the form of water and carbon dioxide to synthesize carbohydrates. The reaction only happens in the presence of solar radiation and oxygen is evolved as a by-product.

The process involves a series of chemical reactions. However, the summary of the whole reactions is represented by the following equation:

carbon dioxide + water ----> glucose + oxygen

Thus, if Emily is to find out how temperature affects photosynthesis. She will need to use a plant as a case study. One factor that can easily be used to measure the rate of photosynthesis is oxygen production by plants.

In other words, Emily will have to set up an experiment where a plant species will be subjected to the same environmental conditions, except temperature. Then, a suitable method will be used to measure the amount of oxygen produced. Any difference in the volume of oxygen produced can then be attributed to the effects of temperature.
