Food preparation is the process that involves planning and preparing of meals. The food prep (preparation) list is a sheet that contains information of ingredients and the amount of each of the ingredients required when preparing a particular dish. The food prep list is part of a recipe which makes the kitchen much more organized and prevents wastage and excessive use of ingredients.
According to the theory of vitalism all the living substances are special and are distinct from the non-living substances, that is, they comprise a unique entity within themselves. This soul or entity distinguishes them from the non-living components.
However, the theory was rejected when urea was taken out successfully from a non-living matter by Wohler, proving the fact that the biological constituents can be extracted from a non-living source. The modern scientists now believe that the living things are just more composite than the non-living substances.
Answer:
One offspring would have red leaves.
Explanation:
Given
Yellow leaves are dominant and red leaves are recessive
Let us assume that the trait of Yellow color of a leaf be represented by "Y"
and the trait of red color of a leaf be represented by "y"
When two parent of genotype "Yy" are crossed with each other, the following offsprings are produced as shown in the punnet square below
Y y
Y YY Yy
y Yy yy
Total four offpsrings are produced out of which only one has red leave as red color is a recessive trait and it will appear only when both the allele in a cell are of red color.
Thus, one offspring would have red leaves.
The first event in the history of DNA studies was Johannsen identifies inherited traits as "genes"
- C. Johannsen identifies inherited traits as "genes"
<h3>Who was Johannsen?</h3>
noting that selection was only effective when based on genetic (genotype) rather than environmental (phenotype) differences.
With this information, we can conclude that Although Mendel conducted his experiments with pea plants in the mid-1800s, it was not until 1909 that Johannsen became the first person to describe Mendel's individual units of heredity. He called them genes.
