Cliffs are created ... I think
The 2pq represents the heterozygotes in the population
Answer:
See the answer below
Explanation:
<em>Zara should keep the clownfish and the goldfish in separate tanks - the goldfish in a freshwater tank and the clownfish in a salt water tank.</em>
<u>If the goldfish is kept in a salt water tank instead of freshwater, it may die due to dehydration</u> because the salt water would be hypertonic to the cells of the fish. Water would move osmotically from the cells of the fish into the surrounding water and the fish may eventually die due to dehydration.
<u>If the clownfish is kept in freshwater instead of salt water, it may die due to excessive water</u>. The freshwater would be hypotonic to the cells of the fish and water would move osmotically from the surrounding water into the cells of the fish. Eventually, the cells would become turgid and may start lysing, leading to the death of the fish.
Endothermic feature distinguishes birds from the rest of the reptiles. So, the correct option is (a).
A crucial adaptation that allowed reptiles to exist on land was the growth of their scaly skin, that stopped water loss from the skin. Ectotherms are animals whose primary source of body heat is the environment. Reptiles fall under this category. They control their body temperature using behavioural strategies including self-heating by basking or self-cooling by seeking cover in burrows or shade.
Birds are endothermic, in contrast to reptiles, which means they produce their own body heat through metabolic processes. The feathers on birds, which are repurposed reptilian scales, are what set them apart from other animals. The first birds' feathers allowed them to glide and eventually take to the air in a flapping motion. They also served to insulate the bird's body and aid in the preservation of body heat.
