Correct answer: A). Earth’s average temperature will increase.
Green house gases are those gases, which are present in the air that have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are known to be found naturally play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
They absorb and emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But due to increased in the concentration of green house gases like carbon dioxide and methane in the environment due to pollution and deforestation is causing a great problem, which result in a global warming, which is a great concern for all the people on the planet. It will increase the annual global temperature which will result in the melting of glaciers. So, the issue of global warming should be taken seriously and adequate measure should be taken to control it.
Answer:
Explanation:
Amount of water displaced by the sphere will be equal to the volume of complete sphere.
As the sphere completely sinks to the bottom of the cup.
We have been given;
Diameter of sphere (d) = 4.6 cm
So,
Volume of sphere (V):
By substituting value of r we get:
1 cm³ = 1 mL
V = 51 mL
So,
Water displaced by the sphere = 51 mL
Answer:
Archaebacteria have cell wall made of complex composition of peptidoglycan
Answer;
The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
Explanation;
-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.
-The process takes place in two phases; light dependent stage and light independent stage.
-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.
-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
