Answer:
This indicates that the expression of genes depends partly on environment.
Explanation:
The case shown in the question is showing a situation where there was a genetic interaction with the environment, resulting that gene expression depends in part on the environment.
Gene and environmental interactions are revealed by penetrance and expressiveness. Penetrance is the percentage of individuals with a given gene that have a phenotype linked to this gene, such as children and parents who have the same height. In cases of penetrance, a genotype may not express the expected phenotype due to gene influences and environmental effects, as happened to the couples' children shown in the question.
An advantage of using sports drinks for fluid replacement during exercise is that:
c. they have a pleasant taste which encourages consumption.
Explanation:
- If you are doing moderate exercise in a very hot environment, you may also lose electrolytes that can't be replaced by drinking water alone.
- Sports drinks can help replenish electrolytes lost during exercise, and because they contain sugar, they can also give you a boost of energy to help you get through a workout
- The best bet for rehydration is to consume a low-cal beverage that contains electrolytes such as sodium and potassium.
- Good choices include sports drinks (go low-cal if your workout), try coconut water, or water with a slice of fruit. The refreshing hint of flavor may drive you to drink more
- During exercise, the main way the body maintains optimal body temperature is by sweating. Heat is removed from the body when beads of sweat on the skin evaporate, resulting in a loss of body fluid.
It depends but it’s really important that you get 7-8 hours of sleep depending on your age
You can do things every day to protect yourself from pathogens. First, you can wash your hands after using the bathroom and before touching food. The pathogens that live in the bathroom could make you sick if they get in your food. By washing your hands with soap and warm water, you can kill most pathogens and keep food safe.
You can also stop germs in the kitchen. Wash fruits and vegetables before eating them. Do not let raw meat touch other foods. Use soap and warm water to clean the kitchen and your hands after touching raw meat. Make sure that anyone who touches food has clean hands. If you are sick, do not touch food that other people might eat. You do not want to spread the pathogens on your hands.
It is also important to wash your hands after handling animals. Some pathogens do not affect animals, but they can make humans sick. For example, reptiles like snakes and turtles can carry a bacteria called Salmonella. This bacteria does not make the reptiles sick, but it can make you sick if it gets in your body. Humans can also spread pathogens to animals. For example, most pig farms require workers to wear special boots and clothing to keep pathogens away from the pigs. Workers also have to wash their boots and clothing if they visit a different pig farm. This special protection is called biosecurity.
If you are already sick, it is important to protect the people around you. Wash your hands and do not share cups or straws with others. If you have to sneeze or cough, cover your face with a tissue or your elbow. You do not want the pathogens in your sneeze or cough to go into the air. Do not sneeze or cough into your hands. The pathogens on your hands can spread to other people.
Vaccines can also stop the spread of pathogens. A vaccine is an injection, or "shot," that teaches the body how to fight a pathogen. Babies often get vaccines to protect them from diseases later in life. Getting a vaccine might hurt, but it keeps the body healthy.
