Explanation: Dogs are endothermic, meaning they can make their own heat by burning brown fat, the fat that is used to generate heat. This is caused by an external stimulus
Strawberries and oranges are high in Vitamin C (in fact, a cup of strawberries has more Vitamin C than a medium-sized orange) as well as potassium. We can thus infer that Layla is probably deficient in these nutrients. To supplement Layla's intake of Vitamin C, Ruby can serve red and green peppers and kiwi, which (like strawberries) have more Vitamin C than an orange. To supplement Layla's potassium intake, Ruby can serve spinach, broccoli, and cantaloupe.
Answer: ideas can change as new discoveries are made
Explanation:
When you find out something new you form new ideas
Genetic variation in a population allows for phenotypic variation, meaning that different traits exist in the same population. When the environment changes, the members of the population are tested by natural selection with regards to how well adapted their specific traits are to the new environment. If the traits they have do not suit their environment, this results in reduced survival and fitness, leading to less of that trait in the population. However, if the traits they have are adapted to the environment, they become naturally selected for with better survivability and fitness (leading to a higher frequency of that trait in the population). Thus, evolution has occurred.
