The right answer for the question that is being asked and shown above is that: "b. Archaeopteryx fossils share traits with both birds and reptiles."
Answer:
Dodos were flightless birds that have been extinct for about 300 years. Imagine that biologists found two surviving dodos and mated this pair of birds. What would you expect of the resulting dodo population after three generations?
The maximum number of alleles present for any gene in the new population is two
Explanation:
As a result of this mating, in the third generation the maximum number of alleles present for any gene in the new population will be two.
Haploid refers to a cell that has has only one copy of each chromosome, like in a gamete such as a sperm cell or egg cell. Upon fertilization, the two haploids come together to form a full diploid cell (two copies of each chromosome) which then goes on to form the complete organism. Monosomy refers to a condition where there is only one copy of a specific chromosome. For example, in the human condition Turner Syndrome, there is only one X chromosome, instead of two sex chromosomes. Most incidences of monosomy other than Turner Syndrome are lethal, so there aren't many examples of it.
The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
Answer:
because parents only give the child 1/2 of their chromosomes
Explanation:
