Answer:
A .a net force greater than zero
B. Unbalanced Force
Explanation:
A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .
B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .
question one is actually mass, and question 2 is D.
Answer:
A scientist discovers a new organism in run-off from the Rio Tinto River in Spain (the river runs through a copper mine and the water has a pH of 2.0). On basic microscopic examination and after conducting a few simple experiments, she finds that this single-celled species is heterotrophic, has no cell wall, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes. Given this information, this new species is most likely a <u>eukaryotic</u> cell in the <u>protozoan</u> subcategory
Explanation:
Eukaryotic cells contain nucleus and organelles and are enclosed by a plasma membrane. Organism that have these cells are protozoa, fungy, plants and animals.
Protozoan are single-celled eukaryotic.
