Answer:

Plants and trees are the primary sources of food for a food chain or a food web. If the population of the primary producers reduces than it affects the whole food web. If the deciduous trees are destroyed due to a fire, there will be less food available for the primary predators. As a result, competition will begin between them and their population will decline. Due to this, the population of other organisms which fed on the primary consumers will also decline.

In terms of energy resources, how do wealthier, developed nations compare
Luden [163]

Answer:

D. People who live in wealthier countries tend to consume more energy per person.

Explanation:

People in wealthy countries have access to many technologies such as phones, televisions, and house appliances like coffee makers. All of these use energy. Wealthy people also tend to have larger houses that require more electricity to light and heat/cool. People in developing countries do not have access to these technologies or large houses that consume large amounts of energy. Additionally, people in poverty are unable to afford the levels of energy that wealthy citizens can. For these reasons, wealthier countries consume more energy per person.

Photo 51 is a picture of the structure of DNA that was used to create a model of DNA. Who created the photo?
Aleksandr-060686 [28]
<span>DNA stands for deoxyribonucleic acid. It has a double strand that contains the genes (a hereditary material) of the organism. It was discovered by James Watson and Francis Crick. Their double-helix structure was based on x-ray diffraction image named as Photograph 51 or Photo 51. It was taken by Raymond Gosling, a pHD student under the supervision of Rosalind Franklin. They used this photo to determine the chemical and physical structure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin</span>
