Speciation will only occur if there was life in the area before like a bunrt down forest or soemthing similar
The correct answer is c. Genetic Variation. Bacteria are very numerous, ad random mutation of bacterial DNA generates a wide variety of change, including resistance.
Answer:
Option 1, 0
Explanation:
Complete question
Flower color in the varieties of pea plants studied by Mendel is controlled by alleles at a single locus. A group of peas homozygous for purple flowers is grown in a garden. All flowers are purple, yet there is some variation in the intensity of the purple color. The estimated heritability for this observed variation in flower color would be
- 0.
- 0.5.
- 0.75.
- 1.
- Cannot be determined without additional information
Solution
Given all the pea plants in the garden are homozygous purple (PP)
If we cross two PP parents, the following offspring will be produces
PP * PP
PP, PP, PP, PP
This means that all offspring are also homozygous purple.
Thus, chances of inheriting variation in the purple color of offspring are negligible. However, the variation in their color can be due to their individual interaction with the variable factors in the environment
Hence, option 1, 0 is correct
Answer:
Explanation:
Lipase is a type of enzyme known as a hydrolase and is responsible for catalysing the hydrolysis of triglycerides (the substrate) into fatty acids and glycerol
Answer:
The reason is because it takes a long time for the light from the stars in the sky to reach earth, so the light the star was producing millions of years ago has just now reached Earth.
