Chromosome non-disjunction, anaphase lag and endoreplication
Answer:
D. in the nucleus
Explanation:
Uranium is a natural radioactive chemical element with the chemical symbol "U" and an atomic number of 92. Uranium is used for generating nuclear fuels which are typically used in powering atomic bombs and nuclear reactors in the field of electricity generation.
When ignited, a uranium compound burns with a green flame. The wavelength of the light given off by this flame is greater than that of ultraviolet light which typically ranges from 100nm to 400nm. Where, nm is represents nanometer.
Basically, when ignited, a uranium compound burns with a green flame having a wavelength of 4.30 x 10^-7m to 5 x 10^-7m.
The energy in uranium is used to make electricity in a nuclear power plant.
This energy is stored in the nucleus of uranium and are released through fission because the uranium atom is highly unstable due to its large number of protons. The nucleus is split spontaneously into several smaller nuclei and thus, releasing energy in the process.
Answer:
They have a backbone, most use legs,wings,or fins for movement.
Answer:
<em>The impact of a drug on cancer. </em>
IV: drug DV: reduced/increased/neutral cancer growth.
<em>Plants grow more when exposed to trap music. </em>
IV: trap music DV: plant growth indicators (height, biomass, etc.)
<em>Exercise improves health. </em>
IV: Exercise regime DV: health indicators
<em>Does the amount of vitamin A in their diet affect the weight of rats? </em>
IV: amount of vitamin A DV: weight of rats.
Explanation:
First, it is imperative to understand what dependent and independent variables are.
<em>Dependent variables are the main variables researchers set out to determine during the course of an experiment.</em> Their values are dependent on some other variables that are inputted by the researchers.
<em>Independent variables are variables that are directly inputted by researchers. </em>Their values can be manipulated or varied to see the kind of effects they will have on dependent variables.
Hence;
- To determine the impact of a drug on cancer, the<u> input/independent variable would be the drug itself</u> while the <u>dependent variable would be the kind of effects they produce on cancer - reduced, increased or, neutral growth.</u>
- Plants grow more when exposed to trap music: the<u> input/independent variable would be trap music</u> while the <u>dependent variable would be heigh, biomass, or any other indicator of growth in plants</u>.
- Exercise improves health: <u>the input/independent variable would be exercise regimes</u> while the i<u>ndependent variable would be indicators of health. </u>
- Does the amount of vitamin A in their diet affect the weight of rats?: <u>the input/independent variable here would be the amount of vitamin A </u>while the <u>dependent variable would the weight of rats.</u>
