Those mutated genes are most commonly recessive. Females have two X chromosomes so they can have a chromosome with the mutated gene and one with the healthy gene. The healthy gene is dominant so the disease won't manifest, and the woman is only a carrier. Males have only one X chromosome and an Y chromosome. If they have the mutated gene on the X chromosome they won't have another X chromosome with the healthy gene.
To summarize, men can't be carriers and they only need one copy of the mutated X-linked gene while women need two copies of the mutated gene.
Answer:
C. Acquired herniations of the muscular colon wall mucosa and submucosa
Explanation:
Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.
The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.
Answer:
True
Explanation:
CSF is produced by choroid plexus. It starts flowing from the lateral ventricles and move towards the fourth ventricle via the third ventricle. It then moves towards the subarachnoid space which is the region surrounding the brain and spinal cord. From the brain and spinal cord, CSF is absorbed through the blood vessels and passed into the bloodstream again. It then moves to the kidney and liver for filtration.
Hence, give statement is true
Local wind patterns and global wind patterns are main causes for cyclonic storms.
<u>Explanation</u>:
Tornadoes are formed over the land, while hurricanes are formed on the water. Hurricanes are formed as of a storm in a tropical area or warm area, on the other hand hurricanes are formed due to different situations in various places. When large masses of air of different temperature and densities meet together, cyclone storms are caused. As the lower density air mass rises and the cooler descents, what is formed is called a weather front, and the coriolis effect makes the front to start spinning and form a funnel. The biggest fuel system is water vapor from the oceans in a tropical storm. The water releases heat and surrounds the air as the water vapor rises and condenses, causing a low pressure, hence the cooler air masses moves to the region with low pressure as the warm air goes up. The spiral begins and a tropical storm is formed. This is how local and global wind patterns affects the formation of tornadoes and hurricanes.
