Answer:
1500
Explanation:
Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.
The total population size of F2 generation = 2000
The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)
Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500
A fossil would from through mineral replacement by replacing the existing material of the animals bones with minerals, to become petrified. The Minerals will keep the fossil preserved longer.

The heart and the arteries of a person, both contracts to pump the blood throughout the body. The aorta, which is the largest artery of the human body, pumps the blood from the heart to the entire body of a person. The oxygen-rich blood is pumped out of the left ventricle when its contraction into the aorta, from where it is transported to the whole body.
Hence, the given statement is true.

<span>Carl Linnaeus was born May 13th, 1707 and died January 10th 1778 aged 70 he was a Swedish botanist which means he performed scientific studies of plants, [ he was also a physician also known as a medical practitioner or medical doctor and a zoologist which is the study of animals. He also started the scheme of nomenclature which is the naming of species of animals and plants; he is also known as the "father of modern taxonomy" taxonomy sometimes alpha taxonomy meaning the science of finding, describing and categorising organisms </span>
