1. The role of bacteria in the carbon cycle is _________________
(a) breakdown of organic compounds (b) respiration
(c) absorption of nitrogen compounds (d) photosynthesis
Answer:
breakdown of organic compounds
Explanation:
Bacteria are responsible for maintaining the conditions of life as the earth by virtue of their powers of decomposition of plant and animal bodies by which the limited supply by C02 available for photosynthesis is replenished. Thus, they act as decomposers in the carbon cycle.

Athletes require energy to move their body. What biomolecules directly supplies your muscles with quick energy, or ATP, when broken down?
Creatine phosphate directly supplies muscles with quick energy, or ATP, when broken down.
Creatine phosphate is a phosphorylated creatine molecule. Muscles use stored chemical energy from the food we eat and convert it to heat and kinetic energy. Adenosine triphosphate is the source of energy used to power the movement of contraction in working muscles. However, ATP is not stored in large amounts in cells. So once muscle contraction begins, the process of making more ATP starts quickly. The muscle has three biochemical systems to produce more ATP for muscle contraction. One such biochemical system utilizes creatine phosphate. Muscles have a little ATP in them that they can use immediately but it does not last long. So, all muscle cells have a high-energy compound called creatinine phosphate which is broken down to form ATP quickly.

plant a is placed in a room by the window and plant b is placed on the open field. assuming all other factors remain constant (same amount of carbon dioxide and water), which plant will have a higher rate of photosynthesis? why? explain your answer.
Answer:
plant B
Explanation:
This is because plant B is exposed to more sunlight which is essential in photosynthesis.
so the chlorophyll is able to trap more sunlight. which will make it have a higher rate of photosynthesis.

O c. Reduce greenhouse gas emissions
O D. Ban CO2 use
Answer:
C
Explanation:
The countries that signed the Kyoto Protocol agreed to reduce greenhouse gas emissions (C) particularly carbon dioxide emissions, in an effort to combat climate change.
What is Kyoto protocol?The Kyoto Protocol is an international treaty under the United Nations Framework Convention on Climate Change that was adopted in 1997 in Kyoto, Japan (UNFCCC). The treaty seeks to address the issue of global climate change by establishing targets for reducing greenhouse gas emissions, specifically carbon dioxide emissions, from industrialized countries.
According to the Kyoto Protocol, developed countries must reduce their emissions by an average of 5.2% below 1990 levels by 2012. The protocol has been ratified by 192 countries, and signatories have implemented a variety of policies and strategies to meet their emissions reduction targets, including increased energy efficiency, increased use of renewable energy sources, and the implementation of emissions trading systems. The Kyoto Protocol is a significant step forward in terms of international cooperation and action on the critical issue of climate change.
