B. Plants need chlorophyll to make food.
C. Carbon dioxide is a by-product of photosynthesis.
D. Photosynthesis happens in some animal cells.

Answers

Answer 1

Answer:

Explanation:

Plants need chlorophyll to make food.

Because,

Animal cells can't make their own food

And photosynthesis never happen in animal cells

Which stage of the cell cycle involves cell growth and DNA replication?

mitosis
cytokinesis
interphase
prophase

Answers

Answer:

interphase aka "c"

Explanation:

During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.

So basically c

write a mini-essay about Balanced & Unbalanced Forces

Answers

Answer:

Forces have a magnitude (strength) and a direction. Forces can be represented as arrows with the length of the arrow representing the magnitude of the force and the head of the arrow pointing in the direction of the force.  Using such arrows, the resulting force (net force) and direction can be determined.

Forces acting on an object can be balanced or unbalanced.

Forces have a magnitude (strength) and a direction. Forces can be represented as arrows with the length of the arrow representing the magnitude of the force and the head of the arrow pointing in the direction of the force. Using such arrows, the resulting force (net force) and direction can be determined. Forces acting on an object can be balanced or unbalanced. Balanced forces will cause no change in the speed of an object.

Balanced forces acting on an object in opposite directions and equal in strength, as shown in the arrows below, do not cause a change in the speed of a moving object.
Objects that are not moving will not start moving if acted on by balanced forces.
For example, in arm wrestling where there is no winner, the force exerted by each person is equal, but they are pushing in opposite directions. The resulting force (net force) is zero. Or, in a tug of war, if there is no movement in the rope, the two teams are exerting equal, but opposite forces that are balanced. Again, the resulting force (net force) is zero. Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving. When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.
The magnitude and direction of the net force affects the resulting motion
This combined force is exerted in the direction of the larger force
For example, if two students push on opposite sides of a box sitting on the floor, the student on the left pushes with less force (small arrow) on the box than the student on the right side of the box (long arrow).
The resulting action (net force: smaller arrow to the right of the = shows that the box will change its motion in the direction of the greater force as shown below:
