Answers

1.True, trees shed their leaves during winter to survive the harsh winter.

2.  True, some trees have leaves that are pointed needles to survive the cold.

Explanation

Trees lose their leaves during winter , during this period, the ground freezes making the soil to be dry as in desert, hence to reduce loss of moisture through transpiration that occurs via the leaves, the trees shed all leaves until warmer springs start. For example deciduous trees in temperate forest shed leaves every winter.

Needle like leaves can survive ice and snow during cold. Insects will not be able to feed on such leaves because of their toughness. In addition to that, needle shaped leaves have lower wind resistance thus can not easily make a tree fall over during big storms.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

i think the answer would be d
