Damage to heart valves can lead to heart murmur.
Explanation:
Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.
The heart murmurs can result due to two reasons that is either a damaged valve or any condition that causes the heart to beat at a faster rate.
The types of damage to the heart valve that may lead to heart murmurs are:
Mitral valve prolapse, Mitral valve or aortic stenosis and Mitral or aortic sclerosis.
Sometimes, the murmurs do not signify a serious condition but under certain condition they may indicate the risk of heart failure.
Answer:
An electrogenic effect
Explanation:
An electrogenic transport is a process where there is a translocation of net charge across the membrane. E.g of electrogenic channels are Na+, K+, Ca2+, and Cl− channels.
The jobs of enzymes, structural proteins, hormones, fatty acids and other important molecules continue around the clock, as do the processes of cellular repair, regeneration and reproduction. Your body gets its needed energy from foods, which are all ultimately funneled into cellular "furnaces" called mitochondria, where nutrients are converted
Answer:
This question is asking to identify the following:
Independent variable: Different humidity levels
Dependent variable: Height of the plant
Control group: Tree left outside in normal conditions
Controlled variable: same time of measurements (once in a week), same types of trees
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, three redwood trees are kept at different humidity levels. Hence, the independent variable is the DIFFERENT HUMIDITY LEVELS the redwood trees were kept at.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this case, the HEIGHTS of the trees measured is the dependent variable.
Controlled variable or constants are those variables that must be kept unchanged throughout the experiment for all groups. In this experiment, the constants are: same time of measurements (once in a week), same types of trees (redwood).
Control group is the the group in an experiment that does not receive experimental treatment. In this case, the group that does not receive treatment/control group is: Tree left outside in normal conditions.
