Pangea. Alfred Wegener presented the idea that the continents was once a super large continent, otherwise known as Pangea, and over time broke and drifted apart into their present positions. It didn't brought out worldwide interests till late 1950s when scientists discovered magnetic particles responding to earth's magnetic field. And from then on, other evidence followed. It basically happened because of Wegener's theory of Pangea.

The table below shows the role of different substances during photosynthesis. Substance Role During Photosynthesis Glucose Store
7nadin3 [17]

Answer:

<em>The correct option is ' Chlorophyll stores chemical energy needed for photosynthesis.'</em>

Explanation:

Chlorophyll traps light energy in the leaves of the plant. Carbon dioxide and water combine in the presence of this light energy to form oxygen and glucose in the process of photosynthesis. Oxygen is released as a by-product of photosynthesis and is passed onto the environment. Glucose is used by the plant for various processes.

Other option, like option A, is wrong because during photosynthesis glucose is produced. It is not the reactant which will react with carbon.

What is the elephant getting when the bond is broken in sucrose?
jasenka [17]

Answer:

Energy

Explanation:

The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.

Using complete sentences explain the consequences of allowing a scientist to withhold information from other scientists and the
agasfer [191]
Allowing a scientist to hide information from the public and other scientists has many consequences. By hiding findings, it can prohibit other scientists from using the findings to further advance the research process. It is crucial that findings are shared so advancements in things such as medicine, mental health, physical health, and  all other sciences can progress to better help people. If, for example, a scientist found that there are links to cancer and sugar, withholding that information from the public would therefore prevent people from taking precautions against cancer.

The increase in the concentration of contaminants in the tissues of animals high on the food chain is termed which of the follow
kirill115 [55]

Answer:

(A) Bioaccumulation

Explanation:

When the concentration of certain substances in the bodies of the organisms of various trophic levels keeps on increasing as they pass through the food chain, the process is called bioaccumulation or biomagnification.

Most of the organic non-biodegradable pollutants/chemicals exhibit bioaccumulation. Being insoluble in water, these chemicals are accumulated in the fat tissues of the organisms.

As the predator feeds on the prey having a non-biodegradable chemical in its tissues, the chemical enters the body of the predator.

As these chemicals pass through the food chain, there is a gradual increase in their concentration stored in the living tissues of the organisms. Therefore, the top consumers exhibit maximum bioaccumulation of contaminants in a food chain.
