First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill. Most iron ore is used to make steel. Here a steel slab is being cut to length in a steel mill.
In a survivable cold environment, an ectotherm is more likely to survive an extended period of food deprivation than would an equally sized endotherm because the ectotherm is using a little amount of its energy for temperature regulation.<span />
Answer:
Cool air falls, this is associated with greater pressures areas.
Warm air rises, this is associated with low-pressure areas.
<u>Explanation:</u>
Due to the <em>differences in air pressure</em>, <em>the wind is blown from 'one location to another location'</em>. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.
Answer:
The leaves of the branches of the forest and garden trees are very valuable roughage for goats in winter. It can replace up to half of the estimated roughage for the day, ie. 4-5 twigs weighing 2 kilograms. The nutritional value of wallets is about 2 times less than that of hay. The most nutritious is acacia, followed by willow, hazel, elm, linden, oak, ash, maple, pear, quiver, poplar, etc. Regardless of the type, the most nutritious are the leaves prepared in June and July, while the branches of the trees are still tender and not completely woody.
