Grey seals breed in habitats where disturbance is kept to a minimal, like rocky shores, ice flows and islands. They feed on cold open waters. When pups are given birth in early winter or late autumn, their skins are white with yellowish tint. They are relatively helpless and rely on their mother's milk for the first few weeks after birth. They deposit a thick layer of blubber that will protect and allow them to adapt to the cold to sustain them when they will hunt for themselves.
A. Plants can make their own food using energy from the Sun.
Animals cannot make their own food.
Explanation:
An example of the physiological capabilities of plants is their ability to make food on their own using the energy from the sun and chemical substances in the environment, animals do not make their own food.
- Physicological ability refers the body functions of an organism. It refers to the life biochemical processes a body is able to carry out based on its design.
- Metabolism is a living function attributable to all life.
- Organisms can either build up energy such as seen in plants during photosynthesis. This process is called anabolism.
- Some other organisms, makes use of the energy in their own life process and this is a catabolic process.

Hibernation is an adaptation that helps animals to survive cold winters.
Hope this helps.
Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
