mark AS BRAINLIEST!!!!!!!

Explanation:

  • Cytoskeleton

-The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including bacteria and archaea.

The cytoskeleton is a network of filaments and tubules that extends throughout a cell, through the cytoplasm, which is all of the material within a cell except for the nucleus.

  • Deciduous plant

-A deciduous tree or shrub is one which sheds its leaves seasonally. ... The process of a tree or shrub dropping its leaves is called 'abscission'.

  • Diffusion

-Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. ... Molecules move from an area of high concentration to an area of lower concentration until an equilibrium is met.

  • Digestion

Digestion is how your body turns food you eat into nutrients it uses for energy, growth, and cell repair. The digestive tract (or gastrointestinal tract) is a long twisting tube that starts at your mouth and ends at your anus.

A fruit is a seed-bearing structure that develops from the ovary of a flowering plant, whereas vegetables are all other plant parts, such as roots, leaves and stems.

  • Gonad

The female gonads, the ovaries, are a pair of reproductive glands. They are located in the pelvis, one on each side of the uterus, and they have two functions: They produce eggs and female hormones.

  • Greenhouse effect

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
