One student did an experiment to find out if fertilizer can make plants grow taller. The steps of the experiment are listed belo

w. Take three pots of the same size. Fill the pots completely with the same type of soil. Plant tomato seeds in the pots of soil. Add different amounts of fertilizer to the three pots. Keep the first pot inside the house, the second pot under the shade of a tree, and the third pot in direct sunlight. Add the same amount of water to the pots every day. Measure the heights of the plants after regular intervals. The results of the experiment were not valid. Which of these statements best describes a flaw in the experiment?

The amount of fertilizer was not the controlled variable.

A control variable is the one which does not receive any treatment in the experiment. Instead it is used to compare the changes in the experimental variable. The control variable remains unchanged in an experiment.

Which molecule prevents a muscle contraction from occurring when the muscle is at rest?
AysviL [449]

Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.

<h3>What is muscle contraction?</h3>

The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.

Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.

In humans, syndactyly (webbed digits) is inherited by possession of a dominant allele (S). If a man who is homozygous and normal
____ [38]

Answer:

The % of children with webbed digits is 50%

Explanation:

Given -

Syndactyly or webbed digits are due to the presence of  a dominant allele (S). Then the allele for normal digits would be represented by allele "s"

A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"

If we cross Ss and ss , then the following offspring are produced -

Ss * ss

Ss, Ss, ss, ss

Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is 50%
