Answer:
B
Explanation:
The allelic combination of the organism is known as its genotype. The genotype is responsible for determining the traits (phenotype) of the organism. However, these traits are not solely determined by the genotype but rather the interaction between the genotype and the environment in which the organism exists.
False, when more cells are made it is reproducing.
over 70 percent of water goes in agriculture irrigation.
In most regions of the world, over 70 percent of freshwater is used for agriculture. By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals.
Answer:
The concept of spontaneous generation was disproved by the idea that life comes from pre-existing life.
Explanation:
The supporters of spontaneous generation theory stated that life did not come from outer space but there is natural spontaneous generation of the living organisms from non-living matter on the earth.
For example, they believed that the decayed and rotting material like mud, straw etc. had the capacity to give rise to organisms like frog, flies, etc.
However, Louis Pasteur by his careful experimentation showed that life comes from pre-existing life.
He showed that in pre-sterilized flasks, life did not come in a closed flask with killed yeast within but in another flask having killed yeast and open to air, new life appeared. Which clearly indicated that pre-existing life forms are present in the air.
Pasteur kept one flask open to air and curved the neck of other one (swan neck experiment) so that the killed yeast present in the flask is not in direct contact with the air.
With his experiment he proved that life cannot come from the non-living object.
