Answer:

The term matter refers to something that consumes space and has mass, the "stuff" of which the universe is made, in other words. All matter consists of substances called atoms, which have different chemical and physical properties and can not be broken down by ordinary chemical reactions into other substances.

Anastasy [175]

Answer:

First, the activity that humans execute that affects their ecosystem positively is reforestation. Second, the activity that humans execute that affects their ecosystem positively is hunting. Their effects rely completely in nature, however, one improves the ecosystem by making it greener and increasing the space nature has to grow, while the other impacts the ecosystem negatively by unbalancing the food chain.

Explanation:

The reasons behind this answer are that in the first place the ecosystem is a very sensitive environment that can be affected by a wide range of factors. In the first place, reforestation helps the environment have better conditions for the animals that live in it, as well as to provide the human race a better quality of air, water and feel better after living in a more natural ecosystem. While hunting breaks the ecosystem's balance because it allows the food chain of the ecosystem to break and allow a general modification.

If one sample food contains 200 cal in another contains 300 cal, which statement applies?
Advocard [28]

<u>Answer</u>:

The food containing 200 calorie have less potential energy than the food containing 300 calorie

<u>Explanation</u>:

The potential energy content of a food material is its stored energy content which is in the form of chemical bonds. This energy can be measured through the combustion of food material inside a calorimeter. A calorimeter is an instrument which is used to measure the total calorie content of the food or other biological samples by measuring its heat content. A Calorie is unit of energy which is in form of heat.

The food material containing carbohydrates proteins and fats have energy in form of chemical bonds.  On the breaking of bond inside the body, energy is released as in the case of glucose breakdown also known as glycolysis.  

The energy released from glycolysis is used to synthesize high energy containing phosphoanhydride bonds. These ATP molecules are a further breakdown in the system to provide energy to the cell to perform various activities.
