2 facts and 1 fib about Kingdom Animalia
GrogVix [38]

Explanation:

Cell Structure

Creatures in kingdom Animalia are all multicellular organisms with eukaryotic cells that have nuclei and organelles. Unlike plants and fungi, animal cells do not have a cell wall. In addition, with the exception of sponges, cells are divided into specialized tissues or organs.

Movement

All Animalia members are mobile at some point in their lives. Motion is achieved through the musculoskeletal system and is one of the factors that allow animals to live in diverse ecosystems including oceans, mountains and deserts. Movement is achieved in various ways including legs, fins and wings.

Food and Respiration

All members of kingdom Animalia are "heterotrophs." They obtain nourishment from other organisms and digest the food internally. In addition, animals utilize aerobic respiration for cellular energy and food breakdown on a molecular level. Oxygen works at a molecular level to complete the metabolic processes necessary to turn fat and sugar into energy for the cells.

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.

PLZ HELP?!!
melisa1 [442]

Explanation:

Gravitational potential energy = mgh, where m is the mass of the mountain climber, g is the gravitational force and h is the height from the base.

Since m and g are constants, the climber's potential energy will be the lowest when he's at the end of the climb, at the base of the mountain. (B)
