Answer:
The correct answer is option A) "the environment that they lived in remained the same, and they were well-adapted to it".
Explanation:
One of the basis of evolution is that species that face new environmental conditions tend to develop new traits to survive. The opposite applies to species that have lived in constant environmental conditions, these species are usually well-adapted and have changed very little over long periods of geologic time. Some species of tortoises are examples of animals that had changed very little in their evolutionary history. The hard shells of tortoises is an ancient adaptation that help them to survive in constant environmental conditions.
Cellulose belongs to carbohydrates.
Cellulose is classified as a carbohydrate, a polysaccharide, as they are formed of the glucose monomers chain. It is the prime component in the walls of the cells of plants, assisting the plants to remain upright and stiff. Humans cannot digest cellulose due to the absence of cellulase, however, it is essential in the diet as fiber.
However, the animals like sheep, cows, and horses can digest cellulose that is why they can acquire nutrients and energy they require from the grass.
Answer:
Explanation:
The human body stores energy through different forms. One of it is by organic food molecules that contains sugar, fat and proteins which are rich sources of energy. Whenever the body doesn’t have enough energy to pull through, it uses these reserves of energy. The molecules start a smart process because instead of releasing all the energy at one, it slowly releases little by little in a process called oxidation (for the body not to run out of energy at once).
For this experiment Julia needs to use a pH probe because it is the only instrument of the given that can be used to meaure the pH continuously.
