Proper use of a condom during sexual activity does not guarantee protection against stis.
Sonja [21]
Answer: True
Sometimes the use of condoms can't prevent STIs(sexually transmitted infections) because of the manufacturer fault.

Stells [14]

Answer:

The common garter snake (Thamnophis sirtalis) is found throughout North America. In the South, it is active year round. In the North, it is active during the warmer months but hibernates during the winter. It is commonly found basking on warm rocks during cool mornings. This lifestyle indicates that the snake is probably <u>heterothermic</u>.

Explanation:

Being heterothermic, like all reptiles, garter snakes bask in the sun to regulate their body temperature. During brumation (the reptile equivalent of hibernation), garter snakes typically commonly den together. Sometimes there will be as many as 100 snakes in one cave. A large, communal or group site is called a hibernaculum they occupy is called hibernacula. These snakes will migrate large distances to brumate.

Snakes do not actually hibernate, rather they become less active during cold weather. It is called "brumation."  Brumation is an extreme slowing down of their metabolism. Snakes are awake, but just very lethargic so you don't see them moving around.

During fall, snakes go back to the previous year’s den. When a sudden cold catches them before they get there, they may die if not fortunate enough to  find a suitable secondary den. They usually do not stay long at the den entrance, but hurry in for the long winter sleep.

Cold-blooded animals like snakes, fish, frogs, and turtles need to spend the winter inactive, or dormant,  because they have no way to keep warm. Snakes will crawl into any area free from frost such as caves, hollow logs, holes under trees and stumps, under wood piles, in other animal's burrows, and occasionally in a person's basement.
