Deep inside the core of the sun, protons can collide into eachother with enough speed that they stick together to form a helium nucleus and generate a big amount of energy at the same time.
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
I've read the story back a couple months ago
Actually, there are many archeologists and anthropologists disagree with dr. Thorne's view. Basically, Thorne strongly believes that what many calls Homo erectus was, in fact, Homo sapiens, and that they migrated out of Africa almost 2 million years ago and dispersed throughout Europe and Asia. That would actually be very different from what scientists have always believed about the evolution of the species. That is why many of them are against him)
I hope I helped :)
