Animal cells are unique in that they do not exhibit cell walls.Plant cells exhibit very stiff pecto-cellulosic walls, notably because of the presence of cellulose microfibrils, the stiffness of which compares to that of steel.
Given that,
Density of the liquid, d = 3 g/ml
Volume, V = 20 mL
To find,
The mass of the liquid.
Solution,
The density of an object is given by its mass divided by volume such that,
d = m/V
m is mass
m = d×V
Put all the values,
m = 3 g/mL × 20 mL
= 60 grams
Hence, the mass of a liquid is 60 grams.
The answer is in asexual reproduction there is only one parent.
The answers are: Timber industry, paper industry, furniture industry.
These three industries depend on the trees so that they are able to make products. The timber industry uses the chopped trees, the paper industry uses the cellulose from the trees as it's basis for production, and the furniture industry makes it's products from certain types of tree. So stricter rules would mean big economic blows for this industries.
