Hereditary diseases pass from parents to offspring via genes during fertilization. If the gene associated with a disease is dominant, it only needs one copy from either parent to express the disease. However, for recessive diseases, one copy of the gene from each parent is needed.
Hereditary diseases are illnesses that are passed from parents to their offspring through genes. This process of transmission takes place through the reproductive cells (gametes) during fertilization.
Each parent contributes one set of chromosomes to the offspring, and therefore, one version (an allele) of each gene. If a particular gene associated with a disease is dominant, an individual merely needs to inherit one copy from either parent to express the trait.
However, for recessive diseases, an individual must inherit two copies of the gene, one from each parent, to express the disease. This is how conditions such as cystic fibrosis or sickle cell anemia are spread from generation to generation.

B) transport substances directly to the body cells
C) require only a small amount of oxygen to function
D) have the opposite function of arteries and veins
Correct answer choice is :
Capillaries are very thin blood vessels that were first found in frog lungs in 1661. They bring nutrients and oxygen to muscles and eliminate trash products. They are only one cell thick, and they are the sites of the transferal of oxygen and other nutrients from the bloodstream to other muscles in the body, they also accumulate carbon dioxide waste elements.
Role of emotions in our lives
Explanation:
Emotions play a major role in our lives. Emotions depict the way how we think and behave in a situation.
Emotions are represented by subjective (feelings and expressions), physiological (reaction of the body through hormones, neurotransmitters, and neural pathways) and expressive(behavior or response) components. Emotions help us to let out our inner feelings and make us feel light. This reduces mental stress and helps to keep the heart healthy.
It helps to make better decisions.
Emotions are the best way to communicate to understand others as well as make others understand us more easily.
Emotions (positive) motivate a person intrinsically to perform well in a given situation or task.
Negative emotions like anger, frustration, irritation etc should be reduced to decrease the stress caused by them and to maintain a healthy body.
