Let's say a geographical barrier separates a species into two different population. Which also cause a reproductive isolation ( the two pupolations cannot interbred)

Throughout the time (lets say a million years), the two populations will undergo a lot of changes in their  respective genomes and eventually will form 2 different species.

If there is no reproductive isolation, the 2 population could interbred with one another and there will be no speciation

1.) Tsunamis typically occur by earthquakes generated in a subduction zone. Most earthquakes happen at convergent boundaries, as they are hitting against each other.

2.) These next two parts are by @HistoryGuy but it's relevant here: 
"Survivors were affected economically because the tsunami destroyed lots of infrastructure that was crucial to the functioning of the economy, such as telephone poles, water works, etc. It affected them socially because it is obviously devastating to endure that kind of loss of life. It affected them environmentally because lots of raw sewage was leaked onto the streets, leading to health issues."

3.) This is from Juenna Aaons and her Prezi,

"I believe it would be different because America and most Western European cities are well off. They have funds, food, water and probably better options for citizens in general after a disaster on a scale as large as this one. I think we'd fix the damage a lot sooner, and most of the survivors would have accommodations right away."

4.) "<span>The countries effected were devastated. There was a massive amount of damage everywhere, and it was going to cost billions. I also think that the communities banded together and helped each other out, I guess it was a bit of a bonding experience as well. Foreign governments and groups also donated money and offered help to the effected nations."

Destiny has distal symphalangism - her fingers and toes are stiff, with tiny nails. She looks it up and finds it is an autosomal
san4es73 [151]

Answer:

1/2

Explanation:

Distal symphalangism is a very rare bone disorder characterized by ankylosis of the distal interphalangeal joints of the hands and/or feet.

Back to the prior issue,

Probability is a field of mathematics that deals with calculating

the likelihood of occurrence of a specific event.

The likelihood of an event is expressed as a number between zero

(the event will never occur) and one (the event is certain). For

example, the probability of an outcome of heads on the toss of a

fair coin is ½ or 0.5. The probability of an event can also be

expressed as a percentage (e.g., an outcome of heads on the toss

of a fair coin is 50% likely) or as odds (e.g., the odds of heads on

the toss of a fair coin is 1:1).

So the probability of her child inheriting her condition is 1/2 since there are only 2 possible outcomes.

AleksandrR [38]

Answer:

The answer is given below.

Explanation:

A tiny difference in a distant enhancer make a blond through DNA Looping.

DNA Looping can bring the enhancer bound by an activator physically closer to the promoter even if the enhancer is located far away along the DNA molecule.

DNA Looping.

When a protein or a set of complex proteins binds to 2 different sites of DNA simultaneously while looping out the interfering DNA.  

Important of DNA Looping

  • It regulates metabolism of DNA
  • it is involved in transcriptional initiation of prokaryotic operons.
