Answer:

Gives strength to cell: cellulose

Selective Membrane: Phospholipids and protein

Explanation:

Cellulose is more common in plants, and it is the material that makes up the Cell wall of plant cells. The main function of a cell wall is to give strength and structure to the cell.

Phospholipids make up the cellular membrane that commonly surrounds animal cells. The purpose of the membrane is to allow certain things to come in and others to leave (selective).

I hope my explanation was clear!

neonofarm [45]

Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, wat
Anna35 [415]

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, watches TV 2.0h, plays tennis 1.5 h, and runs 0.50h daily, If the metabolic rate for sleeping is 70 J/s, for sitting is 115 J/s, for engage in light activity is 230 J/s, for watching TV is 115 J/s, for playing tennis is 460J/s and for running is 1150 J/s.

Answer:

171.8 W

Explanation:

The Average metabolic rate can be deduced by multiplying each entity performed at a some particular hour of time with their corresponding energy, all divided by 24 hours.

Average metabolic rate = \frac{(8.0*70)(6.0*115)(6.0*230)(2.0*115)(1.5*460)(0.5*1150)}{24}

                                        = 171.8 W
