Answer:
In the case of the sea turtles hatching witnessed by Ethan and his family, the behavior exhibited is called an <em><u>instinctive behavior.</u></em>
<em>The sea turtle knows that, the place which they are in (Inside the shells) are not where they are supposed to be in but rather should be inside a water body. Because of these, their instinct kicks in to free themselves from the shell and head towards the ocean.</em>
Explanation:
Answer:
Examples would be
Fungi and the rest are abiotic
Explanation:
biotic factors, can be described as any living component that affects another organism or shapes the ecosystem
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.
Answer:
4. None of the man's children will inherit the mutation
Explanation:
This is because the mutation is somatic. that is it only affect single skin tissues and not carried in the sex-cells,that is not germinal.
Only Germinal mutation that are carried in the sex-cells of either sperm or egg , and transmitted during fertilisation can be be inherited by the offspring.
However, had it mean it was no localized, but metastasis,( spread through the blood stream to the sex-cells,) then it can be inherited by the children. Besides the wife is also negative there is no chance of the kids inheriting the mutation
