The human activity that impacts the weather on Earth negatively is the burning of fossil fuels. When burning the fossil fuels, the temperature on Earth is increased. This causes Greenhouse Gases. The EPA is trying to cut down on the burning of fossil fuels by closing down power plants ran off of coal.

How is heart rate collected during the ymca 3-minute step test to evaluate the cardiorespiratory fitness level of an individual?
vredina [299]

It is measured over a 60-second count immediately following the test.

After completing the test, the individual sits while the fitness professional palpates the radial pulse (within 5 seconds of test completion) and measures the number of heartbeats over the ensuing 60 seconds.

<h3>What is cardiorespiratory fitness?</h3>

Cardiorespiratory fitness (CRF) refers to the ability of the cardiovascular and respiratory systems to oxygenate the mitochondria of skeletal muscle  for the energy production required during physical activity. CKD is an important indicator of adolescents' physical and mental health and academic performance.

Forms of exercise that rely on cardiorespiratory endurance include strenuous distance running, swimming, and cycling. This aspect of fitness  also affects your ability to perform low-intensity, sustained, full-body exercises, such as  walking, without feeling undue fatigue.

Walking briskly, climbing stairs, doing household chores. High levels of physical activity and cardiorespiratory fitness (referred to simply as “fitness” in this article) are associated with reduced all-cause and cardiovascular mortality. In addition, physical activity can reduce the incidence of chronic diseases such as hypertension, diabetes, stroke and cancer.

By studying genetics, scientists have learned that _______ control how organisms develop.
maxonik [38]

Answer:

C. genes

Explanation:

Genes are basic physical & functional unit of heredity. Genes are made up of DNA or we can say that they are segments of DNA which have instructions to synthesize bio molecules known as proteins and these protein molecules are further responsible for characteristics of an organism. Genes are located at a specific location in our chromosomes and the location is known as locus. Almost all the characteristics which an organism has depend upon the kind of information they have in their genes.

During developmental stages, how an organism will develop totally depends upon what kind of proteins are being synthesized at that time and as already explained, protein synthesis totally depends upon type of genes present in the organisms.

When describing cells, this refers to a cell that has yet to develop into a particular cell variant
bagirrra123 [75]

Answer:

The most appropriate answer would be a stem cell.

Stem cells are the undifferentiated cells which have the capability to divide to give rise to more number of the same type of cell.

In addition, these cells have a capability to develop in a particular cell type or specialized cell by the process of cell differentiation.

For example, the embryonic stem is undifferentiated pluripotent cells which are capable of giving rise to almost all types of cells of the body.
