Braxton Hicks contractions.
Braxton Hicks contractions are a tightening in your abdomen that comes and goes. They are contractions of your uterus in preparation for giving birth. They tone the muscles in your uterus and may also help prepare the cervix for birth.
Braxton Hicks contractions feel like muscles tightening across your belly, and if you put your hands on your belly when the contractions happen, you can probably feel your uterus becoming hard.
The contractions come irregularly and usually last for about 30 seconds. While they can be uncomfortable, they usually aren’t painful.
If the pain or discomfort of your contractions eases off, they’re probably Braxton Hicks contractions.

Answer:
Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.
Explanation:
The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.
The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.
It looks like the finals are a triangle assembled by an ensemble. If yes, then each end has area
4 * 3.5 + 3.5^2/4 √3
<h3>The sides are</h3>
- Two reais each 3.5*15
- Two can be each 4*15
Then some all areas = 119 ft
If I got the shape wrong, it's because an equilateral triangle of side 3.5 cannot have height 4.

Answer: In the case of antibiotic resistance, antibiotics cause a selective pressure by killing susceptible bacteria, allowing antibiotic-resistant bacteria to survive and multiply. Selection pressure can be regarded as a force that causes a particular organism to evolve in a certain direction.
