Answer:
Energy is stored in covalent bonds between carbon atoms
Answer:
The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.
Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
The correct answer is (C) Genetically modified crops requires less pesticide.
The genetically modified crops are designed in such a way that it requires less amount of pesticide. These plants contain the gene resistant for pest. These plants are often called as Bt plants. Almost 40% of the maize crops used in United States are genetically modified crops. All these are pest resistant and require very small amount of pesticide to kill some of the pest.
A root structure that protects buds from fire
helps short-leaf pines resist fires
Answer: Option D
<u>Explanation:</u>
Short leaf pine plant in the struggle for existence under hot scorching fire has developed a root structure that protects the buds from fire. This type of pine is called a fire resistant plant as it survives in the canopy of other trees.
Frequent burns have made them resistant to this fire. This is a wonderful example of how some plants survive in this extreme condition where it has to undergo frequent burns.They can also adopt and survive in drought conditions.
