Answer: multicellular
ExplanatioExplanationExplanatioExplanationnn:
<span>Cells responsible of making energy and performing respiration within the cell. Depending on what type of organism they are found at, they can be known as Mitochondria, if they are in animals; and if they are in plants, Chloroplasts.
Mitochondria create energy for the cell by breaking down sugars, fats, and other fuels consumed by the cell.
Chloroplasts, on the other hand, since they are found at plants, convert sunlight into energy.</span>
Answer:
C) Platelets
Explanation:
Hemophilia is caused by a lack of clotting factors. Because platelets (or lack thereof) are what is responsible for how the blood clots, it can be reasonably inferred that the answer is C.
(Platelets secrete procoagualants, which are clotting factors. If there is a genetic issue with how these clotting factors work, then the platelets will not be useful.)
Answer:
Scientist 1
Explanation:
<em>The conclusion of scientists 1 is valid.</em>
Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>
Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.
<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>
