True, air mass is a part of atmosphere. This is also a geography/geology question, not a bio question.
Blood flow reduces when its flow resistance is expanded. Total peripheral resistance is characterized as total blood flow resistance in the systemic circulation. Because of their smaller size and muscle walls the arterioles are effective regulators of blood flow.
Peripheral resistance is the artery's resistance to blood flow. As the arteries restrict the resistance increases and the resistance decreases when they dilate. Three factors influencing peripheral resistance are :
- Autonomous activity: a sympathetic activity which blocks peripheral arteries.
- Pharmacological agents: the vasoconstrictor drugs raise resistance while it is reduced by vasodilator drugs.
- Viscosity of the blood: Higher viscosity enhances resistance.
The extra codons mean the code is more resilient- small errors can still result in the same protein being produced. The other advantage is that in some cases, a single strand of genetic material might code for more than one protein or enzyme, depending on how it is read. This means that one method of reading will produce the same output, but the second or third method of reading (starting from a different place on the strand) can produce other, entirely different materials. This concept is like a palimpsest.
Answer:
To suspend organelles and other subcellular parts.
Explanation:
Controlling what enters and exits the cell is done by the plasma (cell) membrane. Ribosomes synthesize proteins. Nuclei/Nucleoids store genetic information in eukaryotes.
