The answer may be A look man im just here for the points
There are two types of respiration namely aerobic and anaerobic respiration. Anaerobic respiration requires oxygen while anaerobic respiration does not require oxygen. The products of anaerobic respiration (also referred to as fermentation) in yeast are carbon iv oxide and ethanol. Anaerobic respiration has a range of applications in the society which includes Brewing process (bear making process) in alcohol industry, bread making process( baking) in baking industry.
Hi!
The answers would be 1. (D) and 2. (B)
<h3>Explanation of Answer 1</h3>
Ice cores are in essence drilled cylinders that are acquired from glaciers or ice sheets. Ice sheets and glaciers are formed over many years as a result of deposits of snow layers. As these layers form, the lower layers become denser with each new layer, owing to pressure, and in the process it traps the air, which is preserved in the form of bubbles in the layer, therein preserving the composition of the air at a particular period of time. Scientists use ice cores to compare the atmospheric composition of previous years to those of recent years, and the gas mainly studied is carbon dioxide owing to its bringing about a climatic change.
<h3>Explanation of Answer 2</h3>
The Earth's orbit is caused by the gravitational attraction that is present between the Earth and the Sun, but changes due to the shape of the orbit (eccentricity), the wobble of the Earth about its axis (precession), and the axial tilt of the Earth (obliquity). These cause a change in the Earths orbit, which give rise to Milankovitch's cycles. Milankovitch's Cycles describes a revolutionary movement of the Earth around the Sun. These cycles are observed to be determinants of the climate of the Earth, in the regard of how much heat or energy the Earth is exposed to.
