根据第二段 Biology is about all the things in our world that are alive-plants,animals,as well as very small living things that we cannot see.生物学是关于我们世界上所有活着的植物、动物,以及我们看不见的非常小的生物。所以考拉熊是生物,故答案为:B。(2)B 细节推理题。根据第三段 Different kinds...
Photosynthesis is a biological process that helps transfer energy from the sun into chemical energy. Plants and other photosynthetic organisms can convert energy into sugar, which can be utilized to make cellular energy. In photosynthesis, carbon dioxide is built up into glucose. Products of Photosy...
To solve the question of what happens when carbon disulphide is added to a mixture of iron filings and sulphur, we can follow these steps:1. Identify the Components: We start with a mixture of iron filings and sulphur. Iron fil
Why does carbon contribute to pollution? Carbon is used in cars that have carbon fiber as the car heats the carbon wears of not much but maybe 1atom every 10 years causing the carbon to be worn out over millions of years What solutions are there to minimize carbon affect on the environmen...
