Answer:
The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.
It was for studying MIMICRY in snakes.
Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.
This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.
The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.
since it changes in the artificial snake
Explanation:
The features or characteristics of organic compounds include:
1. They contain covalent bonds and are mostly non polar in nature
2. Have lower boiling and melting points than inorganic compounds
3. Many organic compounds are thermally unstable, They decompose into simpler molecules when heated at fairly high temperatures
4. Most organic compounds are inflammable and burn exothermically in sufficient air to yield carbon dioxide, water and heat energy.
5. Most organic compounds being largely non polar are insoluble in water.
Ice core can tells various information regarding the atmosphere. It can reveal the temperature, precipitation, and other atmospheric conditions. Here in the image, the scientists can learn about the ocean surface temperature, i.e., option D.
<h3>What is an ice core?</h3>
Ice cores are ice-drilled cylinders made from ice sheets and glaciers.
They are capsules that are frozen and allow scientists to reconstruct climate far into the past.
It can be used to detect the ocean surface temperature.
Thus, the correct option is D.

<span>Only one sperm normally fuses
with an egg because if more than one sperm fuses, through a process
called polyspermy, development of the zygote usually stops.
</span>
<span>Fertilization of one egg by
two sperm is possible, but the resulting zygote is almost never viable
because such a zygote would have three sets of chromosomes instead of
the normal two. This condition, called triploidy, is usually
incompatible with life. Those rare triploid infants that do survive to
term have severe and multiple birth defects and rarely live more than a
few days. </span>
