a)  Animals respiring with gills are aquatic animals,

b) Warm blooded animals are either mammals and birds,

c)Animal with mammary glands present are mammals.

Aquatic animal:

• Aquatic animals are animals that live and breathe underwater.
• Unlike land animals, aquatic animals have evolved specialized respiratory organs called gills, which allow them to extract oxygen from water.
• Gills are feathery or filamentous structures located on the sides of an aquatic animal's head, and they are rich in blood vessels that absorb oxygen from the surrounding water.
• Aquatic animals use various methods to move water across their gills, including swimming, pumping water through their mouths, and using specialized structures called gill covers or opercula.
• Some examples of aquatic animals that respire with gills include fish, crabs, lobsters, shrimp, and some types of mollusks.

Warm-blooded animal:

• Warm-blooded animals are also known as endothermic animals.
• These animals are able to regulate their body temperature internally.
• Mammals and birds are warm-blooded animals, meaning they can maintain a relatively constant body temperature regardless of the temperature of their surroundings.
• In contrast, cold-blooded animals, also known as ectothermic animals, cannot regulate their body temperature internally and rely on external sources to maintain their body temperature.

• Examples of cold-blooded animals include reptiles, amphibians, and fish.

Female mammal:

• Mammary glands are a defining characteristic of female mammals, as they produce milk to nourish their offspring.
• Male mammals typically lack mammary glands, although there are some rare exceptions, such as male platypuses.
• The presence of mammary glands is used to classify animals as mammals, which is one of the major classes of vertebrates.
• There are many different types of mammals that have mammary glands, ranging from humans and dogs to whales and bats.
• The development and function of mammary glands is regulated by hormones, particularly estrogen and progesterone, which are produced by the ovaries in females.
