The hydrometer displays the density of the liquid you stick it in, COMPARED TO WATER.
If you stick it in pure water, it should read 1.00 . This is a good way to check your hydrometer and see whether it's reading correctly ("calibrated").
Unicellular: An organism that consists of a single cell
Multicellular: An organism with multiple cells
Eukaryotic: A cell that contains a nucleus
Prokaryotic: A cell with no nucleus
Autotrophic: An organism that has the ability to make their own food
Heterotrophic: Organism that cannot create their own food
Asexual reproduction: When an organism has the ability to create offspring without the help of another organism
Sexual Reproduction: When two organisms create an offspring using the gametes
Plants and algae use sunlight to make food. They do this with the process of photosynthesis, and they create excess oxygen as a waste product. The oxygen is vital for other living organisms to survive and perform their daily functions. Hope this helps :)
Answer:
Option b.
Explanation:
Weight of skydiver = mass × acceleration due to gravity
= 113 × 9.81 N
= 1108.53 N
Now,
The weight is acting downwards and air resistance is acting upwards. So,
Net force = weight - air resistance
Net force = 1108.53 - 660
Net force = 448.53
Closest value is option b.
