Answer: <em>The reaction is an example of a metathesis reaction, which involves the exchange of ions between the Pb(NO3)2 and KI. The Pb+2 ends up going after the I- resulting in the formation of PbI2, and the K+ ends up combining with the NO3- forming KNO3.</em>
Explanation:
THE NUCLEUS, BECAUSE FIRST OF THE NUCLEUS CONTROLS MOST OF THE HEREDITARY INFORMATION OF DNA YOU KNOW WHAT IS RIGHT? (DEOXYRIBONUCLEIC ACID) WHICH IS FOUND ON THE CHROMOSOMES. ALL THE OTHER ORGANELLES THAT DOES THERE OWN FUNCTIONS ARE CONTROLLED BY THE NUCLEUS. FOR EXAMPLE:
NUCLEUS: HEY RIBOSOMES!!
RIBOSOMES: YEA BOSS?
NUCLEUS: GO TO THE ENDOPLASMIC RECTULUM AND PRODUCE PROTEINS THERE
RIBOSOMES: YOU GOT IT BOSS!
SEE.... RIBOSOMES PRODUCE PROTEINS FOLLOWING CODED INSTRUCTIONS THAT COME FROM THE NUCLEUS. "THE CONTROL CENTER"
the first answer as blood needs to be oxygenated to be passes round the body then when its deoxgenated it will return to the heart to be pumped around the body again
To protect our eyes from moisture and light. Example: from sweat. It can also reduce the amount of light that gets in your eyes and keep dirt away from them too.
Answer:
C. The rate of photosynthesis increases with an increase in carbon dioxide.
Explanation:
Photosynthesis, which is the process by which certain organisms obtain their food from the light provided by the sun, can be inhibited or promoted by certain factors. One of the reactants of the photosynthetic process is carbon dioxide (CO2), hence, an increase in the amount of carbon dioxide, increases the rate of photosynthesis.
According to this question, two areas with equal sunlight and available water are being described to have different levels or amounts of CO2. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. This means that Area 1 will undergo more photosynthetic activity than Area II.
