Chao should use a flat shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of thin plastic sheets floating on top of the liquid. This part of the experiment will best depict plate tectonics because of the variables that can be seen
hope this helps
Answer:
Cross each to a rabbit who you know is homozygous - i.e. a white rabbit. If there are any white offspring you know this is the heterozygote.
Explanation:
Heterozygous individuals are those with 2 different alleles of a gene. Homozygous individuals have have 2 alleles that are the same.
Imagine the allele for coat color is B black, or b white. If you cross 2 individuals who are homozygous for the black gene (BB), they would only produce black rabbits in the F1 (BB). If you cross the F1, they could only produce BB rabbits in the F2.
However, if you cross a heterozygous rabbit with a homozygous black rabbit (Bb x BB), you would get either BB or Bb rabbits in the F1. However, intercrossing them could produce BB, Bb, or bb rabbits. Therefore, white rabbits can be produced.
You know that white rabbits are bb. So if you are unsure about the genotype of the black rabbit, you can cross it with a white rabbit (either BB x bb or Bb x bb). If any white rabbits appear in the F1, you know there must be a b allele in the black rabbit genotype, so that rabbit must be heterozygous.
Answer:
The correct answer is- founder effect
Explanation:
Founder effect occurs when a small number of individual isolates from the majority of the population by natural calamity or any other region. These isolated individuals show less genetic diversity than the larger population because they are less in numbers.
Therefore founder effect makes a small group of individuals isolate from a bigger population and make them occupy a different habitat. So a founder population can go on a newly developed island and start reproducing there.
A founder population over time converts into a new species because of reproductive isolation from the main population. So the evolution of life on the island of Hawaii should have been most strongly influenced by founder effect.
Answer:
Explanation:
1. can generate energy – Both , In landfills methane gas is produced which is used to generate electricity, like wise heat energy produced in incinerator is also used for producing energy
2. emits toxins through combustion – Incinerators produce dioxins which is a dangerous chemical
3. drains liquids into the ground – Land fill, leachate is a common issue with all landfill site.
4. releases greenhouse gases – Both, methane and other carbon gases are produced in both landfill and incinerators
5. requires a substantial amount of land – land fill site , needs a large land to dump the city waste
6. generate ash – Incenerator only
