Lifestyle is the causal factor a healthy or unhealthy cardiovascular system. Hence, it is important to keep tract on what you eat and practice during the day.
Some common types of cardiovascular diseases and its cause are:
<span>a. Coronary Heart Disease – this is the most common form of heart disease. It happens when arteries supplying blood to the heart narrow or harden from the build-up of plaque (fat and cholesterol). People who experience this condition will often feel chest pains, shortness of breath, and discomfort on the arms, shoulders, neck, and jaw. </span>
<span>b. Atherosclerosis – is a form of coronary heart disease where plaque builds up in the arteries causing low blood supply to the body. </span>
c. Arteriosclerosis – a condition where arteries narrow in size and harden through time
<span>d. Heart Failure – this condition occurs at a very slow rate usually caused by an injury to the heart muscle, uncontrolled high blood pressure, a heart attack, or the a heart valve fails to function. The weakened heart muscle then puts more effort in pumping blood to the body and when the heart can’t keep up with the pace, the heart just fails away. </span><span> </span>
Answer:
The correct option is: b. attenuated vaccine
Explanation:
FluMist is the trade name of the live attenuated influenza vaccine, manufactured by MedImmune. This vaccine is used for the prevention of influenza, also called flu.
It is an attenuated vaccine which is given in the form of nasal spray.
<u>An attenuated vaccine alters the pathogen by reducing its virulence and makes it harmless.</u>
Answer:
Incomplete Dominance
Explanation:
Incomplete dominance is a phenomenon in which the alleles of two genes are not completely dominant over each other and so when they are present at the same time in an organism (heterozygous for that gene) the organism will have an intermediate phenotype that is a combination of both phenotypes.
For example: The flower color in Snapdragon can have three different genotypes as well as phenotypes. The flowers can be red, pink or white depending on their genotype. The allele for red flower (R) is incompletely dominant over allele of white flower (r). A plant with genotype RR will be red flowered and that with rr will be white flowered. However, if a plant has genotype Rr (intermediate), then the flowers will be white in which no allele was dominant over the other and both showed their effect giving a combination of two colors as Pink flowers.
Same is the case with the mating between white and black hen, where offspring was grey in color. This grey was a combination phenotype of two phenotypes.

Answer;
10 seconds
The maximum interval for pausing chest compressions is 10 seconds.
Explanation;
Compressions should be done at a rate of 100 to 120 compressions per minute at a depth of about 1.5 inches for infants, about 2 inches for children and at least 2 inches but no greater than 2.4 inches for adolescents.
The maximum interval for pausing chest compressions is 10 seconds.
