Answer: Arctic foxes have several adaptations that allow them to survive. Their round, compact bodies minimize surface area that is exposed to the cold air. Their muzzle, ears, and legs are short, which also conserves heat.
Explanation:
Digestive juices break down food into the tiniest nutrient components. Proteins are broken down to amino acids; fats are broken down to fatty acids and glycerol; and carbohydrates are broken down into simple sugars for absorption of these vital nutrients. The animal diet needs carbohydrates, protein, and fat, as well as vitamins and inorganic components for nutritional balance. Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body.
During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.
Explanation:
Prophase is divided into 2 sub-phases as early Prophase and late prophase.
Early Prophase:
In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears
By late prophase:
Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.
Metaphase will follow the prophase.
There are different types of observers. Casual observers differ from scientific observer. Seeing and observing are two different things. Not that everybody seeing is actually observing the thing.
A casual observer just sits back and watch for something to happen while a scientific observer comes up with some hypothesis to work on it.
