The Valsalva maneuver involves expiring against a closed glottis, combined with contracting muscles of the abdomen and rib cage to create rigidity in the torso. Thus Option B is the answer.

The purpose of Valsalva maneuver maneuver is to increase intrathoracic pressure, which can be beneficial for certain activities such as weightlifting, defecation, and childbirth.

When performing the Valsalva maneuver, the individual takes a deep breath and then exhales while bearing down and holding their breath. This causes the diaphragm to contract and the thorax to become more rigid, which can help to stabilize the spine and increase the force exerted during a lift or push.

It's also used in medical settings for diagnostic purposes, such as measuring blood pressure. It can be used to diagnose heart conditions such as aortic stenosis and hypertension, it's also used to evaluate autonomic function and it's a routine part of some diagnostic test like barium enema.

It's important to note that the Valsalva maneuver should not be performed if an individual has hypertension, heart disease, or certain other health conditions, as it can be dangerous. It's also not recommended to perform this maneuver for long periods of time, as it can cause blood pressure changes, headaches, and other symptom

There is no integration of the viral genome into the host genome during the lytic cycle. The viral genome fuses with the host genome during replication of the lysogenic cycle and remains there until the lytic cycle is initiated.

In the lytic cycle, viruses produce new copies of themselves inside a host cell before bursting outside the cell. The viral genome is incorporated into the host cell's DNA during the lysogenic cycle, causing internal infection.

Bacterial cells with lytic phages are split open (lysed) and destroyed following an instant virion multiplication. Once the cell has been eliminated, the phage offspring can start looking for new victims to infect.

The host cell is not immediately lysed as is the case with the lysogenic cycle. Temperate phages are those that can go through lysogeny. Their viral genome will merge with host DNA, proliferate along with it in a relatively benign manner, or even take root as a plasmid.

Since the parents are both heterozygous at the eye color locus, the offspring will have a 50% chance of inheriting the p allele and a 50% chance of inheriting the p allele. Since the long-legged trait is dominant, any offspring that inherits the s allele will have long legs. Therefore, the expected percentage of the offspring that will have long legs and purple eyes is 50% (the probability of inheriting the p allele) * 50% (the probability of inheriting the s allele) = 25%.

Warren and Marshall tested the hypothesis that the bacterium Helicobacter pylori are the cause of stomach ulcers.

In the 1980s, Drs. Barry Marshall and Robin Warren proposed the hypothesis that the bacterium Helicobacter pylori (H. pylori) are the cause of stomach ulcers. At the time, it was widely believed that stress and diet were the main causes of stomach ulcers. However, Marshall and Warren had observed that many ulcer patients had H. pylori in their stomachs and that the bacterium seemed to be associated with the development of ulcers.

To test their hypothesis, Marshall and Warren performed a series of experiments. They cultured H. pylori from the stomachs of ulcer patients and then treated the patients' ulcers with antibiotics that targeted the bacterium. They found that the antibiotics were effective in eliminating H. pylori and healing ulcers. They also showed that H. pylori infection could be transmitted from person to person.

Their research was groundbreaking, providing strong evidence that H. pylori were a major cause of stomach ulcers. Their findings led to a change in the way stomach ulcers were treated and also helped to reduce the stigma associated with ulcers as being caused by lifestyle factors such as stress and diet.
