Q: Answer the following question given this paragraph: Plastids are membrane-bound organelles with their own DNA. Examples are chloroplasts and chromoplasts. Chloroplasts contain the green pigment chlorophyll and carry out photosynthesis . Chromoplasts make and store other pigments. They give flower petals their bright colors. Q: What are membrane-bound organelles with their own dna called? A:

OPTIONS:
- vacuoles
- chromosomes
- ribosomes
- plastids

A: plastids

input: OPTIONS:
- nuclear number
- combined number
- mass total
- mass number Now, answer this question: Answer the following question given this paragraph: As you learned in Chapter 1 "Introduction to Chemistry", the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is an integer that is approximately equal to the numerical value of the atomic mass. Although the mass number is unitless, it is assigned units called atomic mass. Q: What number is the sum of the numbers of protons and neutrons present in the nucleus of an atom? A:
A:
output: mass number

Question: Answer the following question given this paragraph: Two forces may act on an object in the same direction. You can see an example of this in Figure below . After the man on the left lifts up the couch, he will push the couch to the right with a force of 25 newtons. At the same time, the man to the right is pulling the couch to the right with a force of 20 newtons. When two forces act in the same direction, the net force is equal to the sum of the forces. This always results in a stronger force than either of the individual forces alone. In this case, the net force on the couch is 45 newtons to the right, so the couch will move to the right. Q: What is the net force when two forces act in the same direction? A:
OPTIONS:
- number of the forces
- arguing forces
- group of forces
- sum of the forces
Answer:
sum of the forces
