The vacuoles are the membranous sacs which are filled with fluid. These spaces inside the vacuoles are free of the cytoplasm and are lined by the membrane. These vacuoles serve the purpose of storage, digestion, ingestion, and excretion. The vacuoles allow the plant cells to attain big size without the accumulation of the bulk.

The vacuoles are present in both plant and the animal cells, however, their size in plant cells is larger. No proteins or microtubules composes these vacuoles.

Hence, the blank can be filled with 'membranous sacs'.

What do bears prefer to eat most
Temka [501]

Answer:

only the basic bears

Explanation:

Black bears are very opportunistic eaters. Most of their diet consists of grasses, roots, berries, and insects. They will also eat fish and mammals—including carrion—and easily develop a taste for human foods and garbage.

Alaskan brown bears are opportunistic eaters and will eat almost anything. Their diet consists of berries, flowers, grasses, herbs, and roots. They get their protein from beavers, deer, caribou, salmon, carcasses, and other small mammals.

Polar bears feed mainly on ringed and bearded seals. ... When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.

A panda's daily diet consists almost entirely of the leaves, stems and shoots of various bamboo species. Bamboo contains very little nutritional value so pandas must eat 12-38kg every day to meet their energy needs.

choli [55]

Answer:

A boy brought a pair home as pets.

Explanation:

As small organisms will not have any major  adaptations for moving quickly or flying to whole another country, hence it is not possible for the snail to travel from Africa to Florida with small animals. Getting stuck on the airplane wing is also not correct as they would have been wiped out by the wind pressure or might have not be able to survive. Hence, the most logical explanation for the snail to get transported to Florida is by a boy who might have brought them as a pet.

Answer:

Scientific names of animals use both the genus and species name, which is much more specific than common names, and gives more information.
