Answer:
Bacterial; viral
Explanation:
Sexually transmitted diseases can be caused by bacteria, viruses, and protozoa. Sexually transmitted diseases caused by protozoa can easily be treated. Bacterial STD can be treated with antibiotics during the initial phase of the disease so bacterial STDs are curable.
Viral STDs are not curable but their symptoms can be managed by taking medication. Viral STDs are not curable because they incorporate their DNA into the host genome and can remain in the latent phase in their host cell.
Answer:
Varicose veins can best be described as veins cannot prevent the backflow of blood.
Explanation:
Varicose veins are a manifestation of venous insufficiency or peripheral vascular insufficiency.
Veins are blood vessels that, unlike arteries, are not able to contract, so they depend on gravity, muscle contractions and a system of valves to be able to carry blood to the heart.
<u>When the venous valves do not work, the blood is not transported properly, backflow occurs and is retained, producing dilation of the vein walls, which is characteristic of varicose veins</u>. In this case, veins cannot prevent the backflow of blood.
The other options are not correct because:
- <em>Varicose veins do not lose their ability to transport blood.
</em>
- <em>Veins cannot be used to transport blood from the heart.
</em>
- <em>Failure to adequately transport waste to the heart does not apply in this case.</em>
