Seedcoat protect the seed during unfavourable conditions.
Answer:
Evaporation.
Explanation:
Evaporation is when water goes into gas state, after being heated up by the sun, different from boiling, which is "artificial" since it's not the sun heating up the water, it's you.
Answer:
Explanation:
Sedimentary rocks are rocks that are formed near the Earth’s surface. It js formed through a sucessive geological processes this include erosion, weathering, dissolution, precipitation, and lithification.
Physical weathering: Sedimentary rocks are layered rocks with many fractures from contracting during cooling. These cracks are opened up as the rock is brought to the surface and it allows water to get in. On freezing the water expands causing the cracks to widen and grow.
chemical weathering. Rain water can be slightly acidic and at times acid rain. This Acid dissolves many minerals particularly in crustal rocks, acid attacks carbonate found in sedimentary rock and feldspar, a principal ingredient of granite dissolving them.
Biological weathering:
Living things also lead to the breakdown of rock into fragments. Roots and burrowing animals physically disrupt rocks leading to the formation of soil.
The results of all the weathering processes is q heap of loose rock fragments and dissolved ions such as salt, bicarbonate, potassium.
The clastics blown away are carried by glaciers from the source region to a catchment area this is called sedimentary basin
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).
Hon, I don't think this is a question. seems more like a piece of info
