Explanation:
the force of attraction towards the centre
of earth or planet is gravity.
for example
- rock in land
- flow of river downwards
- revolution of earth towards the sun
I think the answer would be 2
Answer:
C.Echinoderms have radial symmetry and worms have bilateral symmetry
Explanation:
Echinoderms evolved from animals with bilateral symmetry. The larvae of all echinoderms are bilaterally symmetrical but lost during metamorphosis developing into radial symmetry adult. Examples of echinoderms are starfish, sea urchins, sand dollars.
Worms are invertebrate animals having bilateral symmetry. They have a definite anterior (head) end and a posterior (tail) end. Worms have brains that help them detect objects, food, mates, and predators quickly.
<span>You would use the equation: Molarity M equals amount of solution over volume of solution. So, 0.758 M equals x L divided by 1.55 L OR 0.758 M = x L / 1.55 L . To solve: 1.55 multiplied by 0.758 equals 1.1479. The answer is 1.1479.</span>
