  • This may be at threat because of factors including habitat loss and poaching or over-exploitation.
  • There are many species which are getting vanished day by day due to pollution or poaching, for an instance, pangolins, who have been hunted beyond he limits for their skin, scales, meat, and some body parts are utilized by people in making traditional medicine.
  • The Indian and Philippine pangolin are listed as endangered while the Sunda and the Chinese pangolin are rated as critically endangered by the IUCN, which contributed to the Convention on International Trade in Endangered Species (CITES) prohibiting global trade that had something to do with pangolins or their components.

zhuklara [117]

Answer:

The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.

Explanation:

There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.

Of the statements below, identify the one that best describes the relationship between plants and oxygen.
viva [34]

Answer: A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration.

In the process of photosynthesis the plants in the presence of sunlight, water and carbon dioxide produces a carbohydrates as food and oxygen is liberated into the atmosphere. The process of photosynthesis takes place in day and plants avail oxygen from the roots and leaves for respiration. The food produced is broken down into carbon dioxide and water with the release of energy in the presence of oxygen during cellular respiration. Plants produce oxygen as a byproduct of photosynthesis and use oxygen for cellular respiration.

On the basis of the above information, A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration is the correct statement that describes the relationship between plants and oxygen.

Rufina [12.5K]

Answer: Hey again!

Option (a) is the correct answer.

Explanation:

Elemental form of carbon means the pure form of carbon, that is, carbon is present in its natural form.

An elemental form also means that the pure atoms are not attached to any other atom.

For example, diamond is an allotrope of carbon in which there are only carbon atoms attached to each other and no other atom is present in it.

Whereas methane has carbon and hydrogen atoms attached to each other therefore, it is not an elemental carbon. And proteins include different atoms attached to each other.

Thus, we can conclude that diamond is an example of elemental carbon.
