Vein because they have valves to prevent back flow of blood.
There are 23 chromosomes in each gamete but that includes the two sex chromosomes so you could say each human gamete has 21 autosomes.
Answer:
Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease:
Airway diseases -- These diseases affect the tubes (airways) that carry oxygen and other gases into and out of the lungs. They usually cause a narrowing or blockage of the airways. Airway diseases include asthma, COPD and bronchiectasis. People with airway diseases often say they feel as if they're "trying to breathe out through a straw."
Lung tissue diseases -- These diseases affect the structure of the lung tissue. Scarring or inflammation of the tissue makes the lungs unable to expand fully (restrictive lung disease). This makes it hard for the lungs to take in oxygen and release carbon dioxide. People with this type of lung disorder often say they feel as if they are "wearing a too-tight sweater or vest." As a result, they can't breathe deeply. Pulmonary fibrosis and sarcoidosis are examples of lung tissue disease.
Lung circulation diseases -- These diseases affect the blood vessels in the lungs. They are caused by clotting, scarring, or inflammation of the blood vessels. They affect the ability of the lungs to take up oxygen and release carbon dioxide. These diseases may also affect heart function. An example of a lung circulation disease is pulmonary hypertension. People with these conditions often feel very short of breath when they exert themselves.

Hello there buddy,
<span>RNA is able to hydrogen bond with water (otherwise it wouldn't be soluble), but since water is small and prefers to be able to move around freely, these hydrogen bonds are quite unstable. For that reason, RNA forms much more stable bonds with larger, compatible molecules. Among those, different RNA molecules may bind to DNA or proteins to serve some function, while they can also bind complementary strands of RNA.
</span>
I hope this helps you!
