Answer:
an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment
Explanation:
An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
Answer:
One-half of the daughters of an affected man would have this condition.
Explanation:
Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.
A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.
Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.
Answer:melanism
Explanation:albino is when an animal has no melanin, which is the chemical that causes pigment (color). Melanism is when an animal has too much melanin and is completely black. That animal is melanistic.
The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
