B.
Acid rain isn't much of an issue there.
Global warming has some effect, but not as much.
Greenhouse effect is global warming.
Answer:
D) D = 0.20; d = 0.80
Explanation:
Ok, so first off, we know that the number of homozygous recessive individuals is 64. So 64/100 is the q^2 value. The q value is the square root of that: it is 0.8. Because p + q has to always equal 1, the p value is then 0.2, and the p^2 value 0.04.
So, we know that the heterozygotes had to be 0.16 of the population (1-0.8-0.04 = 0.16).
d has to equal 0.8 because it is the number of recessive alleles in the population, and they give you this too. D is 0.2.
Answer:
b. so organisms will have the same name all over the world
Explanation:
if a universal classification system is followed by everyone, the research, naming and the understanding becomes easier. The names need to be constant for people from every part of the world to know and understand. this prevents any clash of miscommunication between scientist and biologists all over the world. there's a separate branch in science that deals with classifying organisms and giving them names that are universally accepted and followed. it is called taxonomy.
Answer: Option D.
Sexual isolation.
Explanation:
Sexual isolation is a process in which a species of organism is unable to breed or mate from related species successfully due to environment, physiological, behavioral or genetic difference making its to depend on species involved in the cross. Examples is found in amphibians frogs and toads. Breakdown of sexual isolation lead to hybrid sterility, hybrid invaibility or poor gene flow.
