How do eukaryotic plant and animal cells differ from one another?
Ber [7]

Answer:

The eukaryotic plant animal cells are differ having some cell organelles in it.

Explanation:

The first difference is the cell wall, which is present in all eukaryotic plants. It gives shape and rigidity to the plants. But all the animal cell the outer covering is cell membrane. They lack cell wall.

All the plant cell have chlorophyll pigment. It helps them to photosynthesis. In animal cell, chlorophyll molecule are absent. So they depend on plants for their food.

The eukaryotic plant cell more space is occupied by the vacuoles. It stores food and water for the plants. However, animal cells have no vacuole or if present, it is very small in size.

All animal cells have lysosomes, which help in digestion of various materials in the cell. Plants does not contain lysosomes.

Besides this organelles all other structure of plant and animals are similar. They both have nucleus, DNA, cytoplasm, mitochondria, etc.

A fox is a type of mammal that is related to dogs. How does a fox most likely respond to hot air temperatures in a way that ecto
sveta [45]

Answer:

By panting or breathing heavily.

Explanation:

<em>An ectothermic animal is one whose body temperature depends on the temperature of the external environment.</em>

The body of ectotherms regulates temperature depending on the temperature of the external environment where such animal finds itself.

Hence, when the temperature of the external environment rises as a result of hot air, the body of an ectotherm (that is homeothermic, that is, maintain a relatively constant body temperature irrespective of the temperature of the external environment) will adjust so as to keep its temperature relatively constant.

Dogs generally pant (breathe heavily) to bring their body temperature back to normal whenever it rises beyond normal due to rigorous physical activities or high external temperature.

<em>Hence, a fox will most likely pant in response to hot air temperature just like dogs.</em>
