Hey Leeann479!
The chart that shows all the possible combinations of alleles that can result from a genetic cross is called a
Punnett Square! I've attached an example of one to this answer.
Hope this helps!

☁️<u>My Answer☁️</u>:
The two things that identify something has matter are, physical and chemical properties.
⬇️
<u>✫Definitions✫:</u>
A physical property is an aspect of matter that can be observed or measured without changing its chemical composition.
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction.
<u>☼Examples of some major chemical properties☼:</u>
- Flammability
- Toxicity
- Heat of combustion
- pH value
- Rate of radioactive decay
- Chemical stability.
<u>❅Examples of physical properties❅:</u>

This is kind of hard to show without the picture, but to make an ionic bond with Na and Fl you would have the sodium move an electron to the fluorine, so the answer is C! This is because of the fact that sodium has an outer shell valance electron (so it's unstable) and the fluorine would accept that because it is missing an electron in the outer shell. So this sharing would lead to the bond being created!
Answer:
Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.
Example for animals: Animals using glucose and oxygen in diffusion.
Examples for plants: Plants using carbon dioxide to photosynthesize.
