1. Why does the immune system make memory cells?
2. Plants follow a reproduction pattern called alternate generations. Explain the two processes in alternate generations.
3. Describe the difference between sexual and asexual reproduction. Give at least one example organism for each type.
4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Explain why that happens.
But cells in our immune system can remember old foes just fine, and we've never really been sure exactly how they manage it. A new study has filled in missing details on the steps our body takes to remember pathogens, finally revealing the steps our immune cells take to preserve a reference library of past battles.
how are petrified remians formed
Explanation:
Petrified fossils form when minerals replace the structure of an organism. This process, called permineralization, occurs when groundwater solutions saturate the remains of buried plants or animals. As the water evaporates the minerals remain, eventually filling in the spaces left as the organism slowly decays.

Convection in the troposphere causes
•wind •ocean currents •both wind and ocean currents •neither wind nor ocean
Explanation : The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles ) causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. As air rises, expands, and cools, water vapor condenses and clouds develop.
