Answer:
Friction decreased when he went from pavement to ice and then increased two more times.
Explanation:
Thermal energy is always released in exothermic reaction, decreasing the overall catalysis, or speed of the reaction. Heat transfers are common upon vacillations of kinetic energy between molecules.
Answer:
In the middle of the pile of grass.
Explanation:
The fire would be most likely to start in the middle of the piles of grass if spontaneous combustion occurs because the heat doesn't easily move through the medium due to the insulating nature of grass. A pile of grass can catch fire due to spontaneous and quick combustion in the middle of piles of grass. So the fire starts in the middle of the pile of grass.
Answer:
The correct answer is:
D. Gene A is assorting independently of genes B and C, which are linked.
Explanation:
According to the text it is possible to deduce that the first allele of gene A appears with allele of gene B or C half of times. On the other side alleles of genes B or C appear at the same time in 14.4% of the cases. This information shows how A is and independent variable and how B and C are related as they appear together as well.
Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
