Answer:
<em>This phenomenon occurred due to natural selection and evolution.</em>
Explanation:
Natural selection tends to favour organisms carrying the alleles which provide better traits to live in an environment. Evolution tends to change the allele frequency of a species with time depending on the adaptations which are more perfect to survive in an environment.
In the past, blue frogs lived in lakes. The colour of the lake matched with the colour of the frogs. As a result, these frogs could escape from their predators and hence were better adapted to survive in such an environment.
When the lake dried, the blue frogs were not adapted to live in the muddy environment as their colour no longer helped them to escape from the predators. As a result, natural selection favoured those organisms carrying brown colour and evolution changed the allele frequencies and increased the number of brown frogs.
I believe the answer is B, Two humans with different eye color.
My best guess would be C because when you split something up the mix’s of animals decreases and it would be a disturbance
The answer for the above question is the Avascular Necrosis. It occurs as an interruption in the blood flow within the bone resulting in the death of the hematopoietic cells, osteocytes, and marrow fat cells making up the bony structure. It is also called osteonecrosis or ischemic bone necrosis, which occurs when there is loss of blood to the bone, since the bone is a living tissue that needs blood, this interruption of blood supply will result to the death of the bone.
Climate regulation, nutrient cycling, and other ecosystem services are economically valuable and essential for life on Earth.
