Answer:
Explanation:
The right ventricle gets the deoxygenated blood(from right atrium) and pumps blood into the pulmonary artery. The left ventricle gets oxygen rich blood(from left atrium)and pumps it through the aorta.
Answer:
A) igneous rock
Explanation:
Igneous rock is formed when molten rock from underground moves to the surface.
There are three types of rock
1. Igneous rock: This is formed when molten rock (magma or lava) cools and solidifies.
2. Sedimentary rock: As the name implies, it is formed by the coming together of small particles such as gravel, sand, silt, or clay.
Metamorphic rock: This is a rock formed from existing rock. It is formed by the gradual disintegration of existing rocks caused by heat or pressure.
Let's discuss first about difference between micro- and macro-nutrients. Micronutrients are those which are needed in small quantities and their function is not that vast. But macronutrients are the ones which control all the metabolic cycles of the cell, so they are needed in large quantities. This is the basic difference between the two terms.
Proteins are macro-nutrients because they are needed in large amount, as they are involved in some of the most important functions of our body. For example, proteins act as enzymes, involved in immunity, maintaining homeostasis of the body, etc. That is why they are considered as macronutrients.
Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.
<h3>What we know about evolution. </h3>
- This is a theory that was put forward by Charles Darwin.
- Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
- The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
- These changes are hereditary.
Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.
