20. Chromosomes are the genetic material, which is passed on from one generation to the next.
21. A cell plate forms in cytokinesis in plant cells.
22. Cells are the basic units of life.
23. Cell spends most of their life in prophase.
24. Interphase is the division period of the cell cycle.
Answer:
False
False
True
False
True
Explanation:
the first one is false because DNA is the genetic material not the chromosomes.
second one is also false because the cell plate forms in the telophase.
3rd one is true
4th one is false because the cell spens most of its life in interphase not prophase
the 5th one is true

Explanation:
Human made gases that contain a combination of chlorine, fluorine, and carbon. The combination of these gases put a hole in Earth's ozone layer.
A. Chlorofluorocarbons
B. Ozone
C. Global Warming
D. Greenhouse gases
Answer:
D. Chlorofluorocarbons
Explanation:
Chlorofluorocarbons are normally harmless but during combustion it releases an acidic oxide to the atmosphere, it was widely used in the 1900s but due to the hole created in the ozone layer in the South and North poles it was banned from being used in refrigators and air conditioners

DNA makes us all unique by controlling the production of _______that make us look different and have the structures to better survive within our ________.
Answer:
DNA makes us all unique by controlling the production of gene that make us look different and have the structures to better survive within our environment.
Explanation:
DNA is the molecule that contains the genetic information, dependent on the sequence of nucleotides that form its structure.
Chromosomes are formed by a DNA molecule, whose fragments form genes, structures that define every characteristic and function of a living being.
The characteristics expressed by the genes differentiate individuals of the same species and other species, allowing their functions, including survival in their environment.
Every DNA strand has an EQUAL number of adenine and thymine nucleotides in a molecule. Explain why.
Answer:
Explanation: In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff's rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine.

Describe at least three examples of how energy is converted from one form to another
Answer:
1. The chemical energy from food is converted into mechanical energy in order for humans/animals to move.
2. Picture a child moving down a slide. As they go down, that child has kinetic energy. However, when they reach the bottom and stop, the kinetic energy is converted into potential energy. Conversely, at the top of the slide, the child has potential energy which is converted into kinetic energy once they start to go down.
3. Electrical energy from a fan is converted into kinetic energy once it is turned on. The kinetic energy is found within the blades of the fan, where they rotate and generate a cool breeze.
Explanation:
1. Chemical energy --> Mechanical energy
2. Kinetic energy --> Potential energy; Potential energy --> Kinetic energy
3. Electrical energy --> Kinetic energy

_______________________________________________________ like solar cells, biofuels, wind turbines, and ocean waves can be used to replace fossil fuels.
Answer:
Renewable energy
Explanation:
It is a guess but they all seem to be related via how they convert energy but I am blanking on what they might be called.
Renewable sources of energy like solar cells, biofuels, wind turbines, and ocean waves can be used to replace fossil fuels.
What is Renewable energy?Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale.
It includes sources such as sunlight, wind, rain, tides, waves, and geothermal heat.
Thus, Renewable sources of energy and ocean waves can be used to replace fossil fuels.

A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know about the speed and direction of the satellite after the crashes. Why would the crash affect the motion of the satellite, and which crash caused a greater change in motion for the satellite?
Answer:
Crash 1 and the crash would send the satellite into a different direction.
Explanation:
It has more mass meaning it would be heavier meaning that it would cause a greater change in motion.
