Biology

Question 1

the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration

Answer 1

Diffusion in cells

Question 2

The skeleton consists of both fused and individual bones supported and supplemented by ligaments, tendons, muscles and cartilage

Answer 2

Skeleton

Question 3

Muscles have a range of functions from pumping blood and supporting movement to lifting heavy weights or giving birth.

Answer 3

Muscles

Question 4

Organs are structures made up of two or more tissues organized to carry out a particular function, and groups of organs with related functions make up the different organ systems.

Answer 4

Organs and organsystems

Question 5

Specialised cells are cells designed to carry out a particular role in the body

Answer 5

Speacialized cells

Question 6

An organelle is a subcellular structure that has one or more specific jobs to perform in the cell

Answer 6

Cell organelles

Question 7

Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules. Animal cells often have an irregular shape

Answer 7

Plant and animal cells

Question 8

defined as movement of molecules across a membrane by a concentration gradient, while facilitated diffusion occurs if molecules cross the membrane via a protein channel or carrier. Active transport happens when molecules are pushed against the concentration gradient. This requires energy.

Answer 8

Diffusion

Question 9

structures made up of two or more tissues organized to carry out a particular function, and groups of organs with related functions make up the different organ systems

Answer 9

Organs and organ systems 🙉🙉🙉🙉

Question 10

a range of functions from pumping blood and supporting movement to lifting heavy weights or giving birth. Muscles work by either contracting or relaxing to cause movement. This movement may be voluntary (meaning the movement is made consciously) or done without our conscious awareness (involuntary).

Answer 10

Muscles

Question 11

consists of both fused and individual bones supported and supplemented by ligaments, tendons, muscles and cartilage. It serves as a scaffold which supports organs, anchors muscles, and protects organs such as the brain, lungs, heart and spinal cord.

Answer 11

Skeleton
