Answer:
Invertebrates can have bilateral or radial symmetry, or they can be asymmetrical. Bilateral symmetry means that the animal is arranged in the same way on both sides. Radial symmetry means the body parts are arranged in a circle around a central point.
Enzymes can be best described as catalysts in living systems. This is because enzymes accelerate chemical reactions without being used up in the process.
The process in which the environment<span> selects </span>organisms<span> that will survive is called natural selection. It starts with overproduction; when an </span>organism<span> produces more offpsrings than can survive. The second is variation. Because there are so many offsprings, there will be variations.</span>
1. True.
2. Given: Mass = 30 Kg
Acceleration = 2.0m/s2
Force= mass x acceleration
Force= 30Kg x 2.0 m/s2
Force= 120 N
3. Given : Mass = 30 Kg
Force= 180 N
Force = Mass x Acceleration
Acceleration = Force / Mass
= 180 N / 30 Kg
Acceleration = 6.0 m/s2
