Earth formed 4.6 billion years ago, and it wasn't until approximately 3.5 billion years ago that we estimate the first prokaryotic unicellular organism existed. The first eukaryote organism probably evolved 2 billion years ago, with the first multicellular organisms evolving about 1 billion years ago.
If 1 centimeter (cm) represents 10 million years (mya), then the 4.6 billion years of the existence of Earth would represent 4.6 meters (m), with the 4.6 m mark being the present.
This means that if we made a timeline with these dimensions, the origin of life would be at the 1.1 meters (110 cm) mark, the eukaryotic life forms appearing at the 2.6 m mark, and the first multicellular organisms around the 3.6 m mark.
I believe the answer is frequency
Answer:
If gametes (sperm and egg) were made by mitosis, then they would be diploid. ... A tetraploid zygote is not viable and will most likely miscarriage.
Explanation:
Answer:
A. 22.85 mL of oxygen
Explanation:
Data:
The total volume of Oxygen =500 mL.
Percentage of Oxygen inhaled= 20.94 %
Amount of Oxygen inhaled =20.94 /100 x500 ml
=104.7 ml
Percentage of Oxygen exhaled = 16.37 %
Amount of Oxygen inhaled =16.37 /100 x500 ml
=81.85 ml
Difference b/w amount of oxygen inhaled/exhaled= 104.7 ml-81.85 ml
=22.85 ml
Therefore, Option A is correct option.
