Answer:
A: This matters because If they occur in a Pattern this means the shift over a large period of time. Thus claim #2
B: This matters as stated in A we now know it occurs in a regular pattern meaning the shift occurs over a large period of time.
C: This is important because we know that earthquakes happen regularly which can sometimes volcanic eruption when plates shift as magma is exposed thus claim 2
D: This is important because this shows us that if the plates only move 3 cm a year and the same fossil species is 4,000 miles away we can infer that these plates have been spreading apart for a very long amount of time thus claim 2
Explanation:
What are the answer choices?
I am not sure if this counts, but maybe seals and whales.
Answer:
Body colour and wing shape are linked genes
Explanation:
Suppose,
body color gene = A
wing shape gene = B
A test cross is being done between heterozygous but phenotypically wild type parrot ( AaBb ) and white parrot with deformed wings (aabb):
If the genes showed independent assortment, the ratio of progeny in this test cross would have been 1 : 1 : 1 : 1 i.e. all the different types of progeny would have been almost equal to each other in number
But according to the given data, the progeny is :
wild type : 720
white - deformed wings : 780
white - normal wings : 280
gray - deformed wings : 220
Hence, the number of offspring is not same in each category. Few combinations have higher number of parrots and others have lower number of parrots than expected value. This is a classic example of two linked genes where the parental type is produced in more numbers than the recombinant type.
The process in which green plants use sunlight to make their own food.
Photosynthesis is necessary for life on Earth.
Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
It is the number one source of oxygen in the atmosphere.
