The answer should be A capillaries
I am guessing an Ecological Relationship as it is dependent on it's environment
Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.
Answer:
Option (A)
Explanation:
Environmental justice usually refers to a significant portion of the struggle that is extensive carried out in order to improve, upgrade and maintain a clean, hygienic and healthy environment. This struggle is mainly for those people who have traditionally lived, worked and was closely associated with the sources of various types of pollution.
This can also be simply considered as precautionary measures that are taken in order to prevent nuclear destruction, creation, and disposal of hazardous waste materials and other factors that have the potential to affect the resources on earth such as land, wind, water, and food.
Thus, the above given dimensions of environmental problems are issues of environmental justice.
Hence, the correct answer is option (A).
83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
Explanation:
Molarity or molar concentration is the number of moles of solute that can be dissolved in 1 L of a solution.
let us find the number of moles
n=C*V Concentration is 0.75M
Volume is 1000ml.
n= 0.75*1
n= 0.75
This means there are 0.75 moles of CaCl2 in 1000 ml of solution of .75M.
Molar mass of CaCl2 is = 40.08+ 2(35.5)
= 110.98 gms
Thus 1 MOLE OF CaCl2 weighs 110.98
so 0.75 moles will weigh 110.98*0.75
= 83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
