The answer of your question is option "B": "Matter is anything that has mass and takes up space". So, by this definition, we know that matter has mass and volume and both of them can be measured.
There are many examples of matter: a pencil, a rock, animals, books, planets, even people are made of matter. So we are sorrounded by it.
Answer:Sample Response: The law of conservation of mass states that the total amount of mass remains constant in a system. In ecology, this means that when an organism is eaten, its mass is conserved. Some of the organism’s mass is used to make new proteins, and some of it is passed as waste in the form of urine or feces. The rest is converted directly into energy. This energy helps the consumer to move and grow, and it helps it to build and repair new tissue.

Answer:
Average speed: 86 km/h
Explanation:
Driving from San Antonio to Houston:
1st. half time: 54km/h
2nd. half time: 118 km/h
Average speed = [tex] \frac{54 \frac{km}{h}+ 118 \frac{km}{h} }{2}=86 \frac{km}{h} [\tex]
Driving way back:
1st. half time: 54km/h
2nd. half time: 118 km/h
Average speed = [tex] \frac{54 \frac{km}{h}+ 118 \frac{km}{h} }{2}=86 \frac{km}{h} [\tex]
As in both routes we have the same average speed, then the average speed for the whole trip is 86 km/h
