What are some examples of physical evidence that support scientific theories that Earth has evolved over geologic time?
mel-nik [20]
Some examples of physical evidence that supports scientific theories that earth has evolved over geologic time are the studies have have been done supporting the idea of Pangaea that all the continents were together and with time separated, if you look at a map you can see that the continents almost fits like a puzzle, of course they do not because of erosion and climate change, but it’s the closest example.

. Jack and Jill are thinking about starting a family and they come to you with a question about a rare recessive genetic disease
cupoosta [38]

Answer:

The chance of  having a Child who is a Heterozygote  is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%

Explanation:

Jack  has a history of Alpers in his family

Jill has no history

lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal  years )

Jill : AA

Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below

AA * Ab = AA , Ab, AA, Ab

The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome

If the nucleotide sequence on one side of a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will b
valentinak56 [21]

Answer:GGATCGA

Explanation:

The complementary double helix of the DNA are antipararell to each other.

Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).

Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below

5' CCTAGCT 3'

3' GGATCGA 5'

What index provides evidence of when different types of life evolved on Earth?
aev [14]

There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the “molecular clocks” in the DNA of living organisms.

There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened.

Modern genetics allows scientists to measure how different species are from each other at a molecular level, and thus to estimate how much time has passed since a single lineage split into different species. Confounding factors rack up for species that are very distantly related, making the earlier dates more uncertain.

These difficulties mean that the dates in the timeline should be taken as approximate. As a general rule, they become more uncertain the further back along the geological timescale we look. Dates that are very uncertain are marked with a question mark.
