A basketball with a mass of 0.60 kg is accelerated with a force of 10.8 N. If resisting forces are ignored, what is the acceleration of the basketball to the nearest m/s2?

Answers

Answer:

18 m/s^2 A newton is defined as kg*m/s^2 and you want to accelerate a mass in kg, getting a result of m/s^2. So what you need to do is cancel out the kg unit in the newtons. You can do that by dividing the newtons by kg. So let's do the math. 10.8 kg*m/s^2 / 0.60 kg = 18 m/s^2 So the ball has an acceleration of 18 m/s^2. Remember, look at the units you have and the units you desire. By doing so, the math operations become obvious.

O A The materials need to Love through the cytoplasm to get to the mitochondria
B The cell membrane lets the materials into the cell so they can get to the mitochondria
OCThe cell wall lets the materials into the cell so they can get to the mitochondria
D. The materials need to move through the lysosome to get to the mitochondria

Answers

Answer:

C. The cell membrane lets the materials into the cell so they can get to the mitochondria

Explanation:

The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

In science, a theory is different from how we use the term "theory" to apply to everyday ideas. The statement "It’s only a theory" might mean something very different than "theory" when used as a scientific term. What is the best way to explain the word, "theory" when used in science?

A. In science, there is no difference between a law and a theory.

B. In science, there are few principles that can be considered theories.

C. In science, a theory is well supported by observations and/or experimental data.

D. In science, a theory is a completely accurate and reliable fact about natural events.

Answers

Answer:

C

Explanation:

The correct answer would be that in science, a theory is well supported by observations and/or experimental data.

Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.

Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.

The correct option is C.

What would be the main problem with reproduction if meiosis did not take place to form sex cells?

Answers

Answer:

Fertilization would result in a zygote with twice as many chromosomes as the parents.

Explanation:

Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.

Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.

Answer:

B) Fertilization would result in a zygote with half as many chromosomes as the parents.

Which best explains how to oxygen Atoms,
each with six valence electrons can bond with each other?

Answers

Explanation:

Two oxygen atoms bonds with each other via covalent bonding.

In the formation of covalent bonds, two atoms with little to no electronegativity difference combines by sharing of the valence electrons. This why homonuclear molecules can be formed.

Two atoms of the same kind having zero electronegativity difference forms this covalent bonds. There is equal sharing of electron pair between the atoms and there is no electrostatic charge on the molecule.

For the oxygen atom with 6 valence electrons;

   two electrons are shared by each atoms to make a complete octet and a stable molecule.
