It affects it by the warm waters in the gulf stream. Making the temperature up near Great Britain and Ireland Portugal etc. Much more mild then it would be per say in Eastern Canada. It's mainly affected by the Gulf Stream having it's waters flow upwards towards the countries listed.
Deletion would be your answer isnt this a exam???
Answer:
Part a:
Whales and sharks share a common ancestor for superficial characteristics
Part b:
The vestigial pelvic bone of whales and dolphins indicates that they descended from an ancestor that lived on land.
Explanation:
Part a:
Whales and sharks possess similar body shapes and fin positions not because of descent from a common ancestor but due to their shared aquatic habitat. Whales share more characteristics with humans than with sharks. This indicates close phylogenetic ties (ancestral similarities) between humans and whales whereas sharks and whales have evolved independently. If they shared a common ancestor, they would have similar anatomical characters as well.
Part b:
Vestigial Structure:
A vestigial structure is an anatomical characteristic that is believed to have served a specific function for an organism in the past but as the organism evolved, the structure lost its function.
Pelvic bones are required by animals to move their lower limbs to be able to walk on land. Whales possess vestigial pelvic bones because they have evolved from an ancestor that lived on land.
They all produce heat and light, they will all eventually die out. Sorry its been a while since I've been on this topic so I can't get specific. <span />
Answer:
See below
Explanation:
Hershey and Chase Experiment:
Viruses, such as T2 Bacteriophage infect by injecting their genetic material into a cell. When Hershey and Chase used radioactive isotopes of sulfur (marking proteins) and phosphorous (marking DNA) and saw which was injected into the cell by the T2 Bacteriophage, sulfur was found outside while phosphorous was found inside the cell. That means that DNA was injected into the cell, not proteins. As the genetic material is injected into the cell to hijack it, and as DNA was injected inside while proteins remained outside, DNA is the genetic material.
