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.
Basketball was invented by the Canadian James Naismith in 1981.
TRUE
It can damage nearly every organ in the body, including the lungs, heart, blood vessels, reproductive organs, mouth, skin, eyes, and bones.
Smoking damages the airways and small air sacs in your lungs. This damage starts early in smokers, and lung function continues to worsen as long as the person smokes. Still, it may take years for the problem to become noticeable enough for lung disease to be diagnosed.
Smoking makes pneumonia and asthma worse. It also causes many other lung diseases that can be nearly as bad as lung cancer.
<u>Explanation:</u>
Homeostasis refers to the internal body system that helps to regulate our internal body environment, such as our temperature, blood pressure, etc.
By means of<em> internal sensors</em> which monitor when there is a change in our normal body condition, these reaction times occur for example:
- when we are triggered by our body to go and dehydrate (urinate) in the restroom,
- or maybe when we begin to sweat heavily after performing physical activity, those tiny droplets of sweat helps cool our body down.
All these automatic responses help us maintain homeostasis in our body.
