Biology
1 answer:
nikitadnepr [17]3 years ago
4 0

Answer:

The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. Made of specialized and unique cardiac muscle, it pumps blood throughout the body and to the heart itself.

Claps shut at birth. Evolutionary changes in the vertebrate heart are tied to change from single to double-circuit heart, with increased separation of oxygenated and deoxygenated blood, allowing more efficient respiration and circulation to fuel high activity and increased oxygen demands associated with endothermy.

Granite takes much longer to form than basalt. How will the size of the crystals in granite be different from the size of the cr
anastassius [24]

Answer:

The size of the crystals in granite will be different from the size of the crystals in basalt depending on how they are formed and how they are cooled which determines the nature of the crystals they produce. Granite takes a much longer time to form than basalt because granite takes a very long time to cool down since it is intrusive giving minerals to be well-formed and producing a bigger size of crystals with individual mineral grains that are can be seen without the need for bigger magnification. While basalt crystals are much smaller as the crystals form very quickly because the magma comes out of the earth and cools quickly giving rise to fine-grained minerals.

Explanation:

Granite and basalt are both igneous rocks.

Granite takes a longer time to cool as it hardens under the earth's surface causing the delay in cooling while basalt takes a shorter time to cool as it hardens above the earth's surface.
