Many organisms that undergo chemosynthesis use ________ instead of ________ to fuel the processes that convert carbon dioxide into sugars.
a. energy; sunlight
b. hydrogen sulfide (H2S); sunlight
c. sunlight; water
d. sunlight; carbohydrates
e. sunlight; sulfuric acid
Answer:
b. hydrogen sulfide (H2S); sunlight
Explanation:
Some autotrophic organisms do not use the energy of sunlight to fix the inorganic simpler substances such as CO2 into the organic sugars. These organisms perform oxidation of chemical compounds. The energy released from the oxidation of organic or inorganic chemicals is used to fix CO2 into sugars. These organisms are called chemotrophs. Some chemotrophs such as sulfur-oxidizing bacteria use H2S as a source of energy to fix CO2.
~Hello there!
Your question: A living organism represents stored energy in the form of chemical compounds. when an organism dies, what happens to this stored energy?
Your answer: The chemical compounds in the cells lost their organization later because there is no input of energy to sustain the organized state.
Any queries?
Happy Studying ^=^
If being short is the dominant trait, then you should expect the offspring to also be short.
This is because the traits are spread out as four different possibilities. Either FF, FF, Ff, or Ff. If the dominant trait is being short, “F” then this would mask the recessive trait “f”.
Answer:
A. broad spectrum
Explanation:
An antibiotic is a substance that has the capability to inhibit the growth of or kill bacteria.
A broad spectrum antibiotic has the capability to be inhibit or kill a wide range of bacteria species while a narrow spectrum can only operate within a narrow range of bacteria species.
<em>Hence, in a situation where the the causative organism of the disease (the pathogen) is not known, it is better to use a broad spectrum antibiotic because such antibiotic has a higher chance of eliminating the pathogen.</em>
