Please answer this: What is the missing first step of the following process: - Animals gain weight - The season changes to one with bad (cold, snowy) weather - Animals find a place to hibernate - Animals enter a type of 'sleep' (hibernation) - Body processes slow down - The animal's heart rate and breathing rate slow - The animal loses weight more slowly than usual - The animal is able to survive not eating or drinking without hurting itself -

Answer: Animals eat a lot during good (warm, clear) weather

Problem: What is the missing first step of the following process: - The roots absorb water and minerals from the soil - This combination of water and minerals flows from the stem into the leaf - Carbon dioxide enters the leaf - Light, water and minerals, and the carbon dioxide all mix together - This mixture forms sugar (glucose) which is what the plant eats - Oxygen goes out of the leaf through the stomata -

A: Chloroplasts in the leaf of the plant traps light from the sun

Problem: Given the question: What is the missing first step of the following process: - As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it - The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack - Clay expends when wet like ice does - This causes rock to break apart - Some plants like mosses and lichens are capable of growing without soil on bare rock - When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks -
++++++++++++++++++++++++++++++++
The answer is:
When water freezes it becomes 10% bigger, or takes up 10% more space
