<u>Answer:</u>

The sun’s spectrum though not a continuous spectrum allows us to represent the visible radiation. The spectrum from the sun has missing parts because the lights gets absorbed and not because of the sun.

Continuous spectra are discharged by any article that emanates heat. The light is spread out into a consistent band with each wavelength having some measure of radiation. For instance, when daylight is gone through a crystal, the light is spread out into it's colors.

When light passes through the sun’s atmosphere the spectrum is absorbed. The sun’s spectrum consists of seven colors VIBGYOR. When sun’s rays fall into the prism they are disbursed into seven colors.

tatiyna

Answer:

This question is incomplete; but from the understanding of the question, it is about identifying the variables in the experiment e.g independent variable, dependent variable, control variable, control group etc.

The variables are as follows:

Independent variable: HEAT at different temperatures

Dependent variable: GROWTH OF MOLD

Constants/Control variables: Same amount of food, Same type of food

Control group: Jars kept at 0°C

Explanation:

A variable in an experiment are those factors that are subject to change. The INDEPENDENT VARIABLE in an experiment is that variable that is manipulated or controlled in order to bring about an outcome. In this Sarah's experiment, the independent variable is the HEAT CHANGE.

The DEPENDENT variable is the variable that responds to the changes made to the independent variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the GROWTH OF THE MOLDS because it responds to changes in heat (independent variable).

The CONSTANT or CONTROL variables in an experiment refers to the variables that are kept constant or unchanged throughout the experiment. Although they are not part of the experiment but they can affect the outcome of the experiment if changed. The constants in this experiment are the SAME AMOUNT and SAME TYPE OF FOOD given to each jar.

A CONTROL group is the group that does not receive any experimental treatment I.e. In this experiment, the jars placed at 0°C did not receive any heat, hence, they are the control group.

The experimental groups were the jars kept at 90°C and 27°C respectively.

Answer:

human embryonic stem cells are obtained from embryos, thereby they are subject to ethical, religious, political and legal considerations

Explanation:

Human embryonic stem cells (HESCs) are pluripotent undifferentiated cells derived from blastocyst-stage embryos, which have the ability to produce any type of somatic cells. HESCs are obtained <em>in vitro</em> from embryos that are 5-6 days old. These cells are valuable tools in research in order to understand the genetic and physiological mechanisms of human development, as well as to develop treatments against diseases. The use of embryonic stem cells in research is controversial because these techniques involve the destruction of human embryos, and there are people who consider human life begins with the formation of the diploid zygote after fertilization, thereby raising the debate if a human embryo can be regarded as a human being.
