Why is evolution considered a theory

Biology
1 answer:
fgiga [73]2 years ago
6 0
Because evolution has not been explicitly proven. There has been some evidence, but there is not enough real proof to support this. Even the man who invented the theory of evolution ended up not believing in his own theory at the time of his death. Overall, the premise of evolution is built on an unstable rock, a theory.

Deoxyribose Glucose Guanine Phosphate Ribose
Sergeu [11.5K]
There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate. 
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and <u>guanine -G</u>), a monosaccharide <u>deoxyribose</u>, and a <u>phosphate </u>group. <span>By knowing this, it is easy to choose which molecule of those is the DNA.</span>

Murrr4er [49]
There are 11 organelles in total, 
vacuoles: they store water
Chloroplasts: trap energy from the sun to produce food for plant cell
Cell wall: provides support and protection to the cell membrane, 
Cell membrane: thin flexible barrier around a cell, controls what enters/ leaves the cell
Nucleus: 'The control center', carries the DNA of the cell
Ribosomes: Found in all cells, their jobs are to make protein 
Endoplasmic Reticulum: The internal delivery system of the cell
Golgi complex: Transports materials throughout the cell
Lysosomes: Break down food into particles the cell can use. another function is they destroy old or dying cells 
Mitochondria: Breaks down food to make ATP 
and last but not least cytoplasm a jelly like fluid in the cell that keeps the organelles suspended

Find the kinetic energy of a ball moving at 45 m/s with a mass of 0.18kg
mamaluj [8]

Answer:182.25 joules

Explanation:

Mass=0.18kg

Velocity=45m/s

Kinetic energy=(mass x(velocity)^2)➗2

Kinetic energy=(0.18 x 45^2) ➗ 2

Kinetic energy=(0.18x45x45) ➗ 2

Kinetic energy=364.5 ➗ 2

Kinetic energy=182.25

Kinetic energy=182.25 joules
