Sodium is an example of an alkali metal. The alkali metals are found in the leftmost column of the periodic table, known as Grou

p 1. Use the interactive periodic table to explore the properties of the following alkali metals: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical property common to alkali metals: they react with water. How does the reactivity vary among this group of elements? Why might patterns like this be useful to scientists?

Answer:

The reactivity greatens the farther you go down on the periodic table. Lithium will have the weakest reaction, and cesium will have the greatest reaction. Patterns like this are useful to scientists because it shows which elements are the most reactive and which aren't. The farther down and to the left you go within the periodic table, the more reactive the elements become. The farther up and to the right you go, the less reactive they become.

Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabil
Zanzabum

Answer:

50% probability of Pp (purple) or pp (white) genotype.

Explanation:

P = purple gene

p = white gene

Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:

Purple flower genotype (heterozygous) = Pp

White flower genotype = pp

Punnet Square:

\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]

Potential genotypes for offspring are Pp and pp;

According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;

This means 2 should be purple and 2 white;

Or, there is a 50% chance of having either genotype, of being purple or white.

Why is redi's experiment a good example of a controlled experiment
Step2247 [10]
A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.

Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.

This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.

Redi was trying to prove spontaneous generation with his experiment. Although, it failed.

Spontaneous generation: When life forms from non-livings.

Redi disproved spontaneous generation, but proved biogenesis.

Biogenesis: When life comes from other living beings.

He proved biogenesis because the flies had reproduced when the jar was opened.
