Answer: Independent variable is what is being modified, it is important to compare it to your control group, (which is the original).
Dependent variable is what is being measured, to compare it to the control group to see if your hypothesis works or not.
Explanation: Here's a(n) example:
Bob wanted to take a mint with a mint drop, and he wanted to measure if it can make his breath fresher, but he also wanted to take it with a regular mint to see which is the freshest breath.
Independent variable: Mint drop.
Dependent Variable: Breath (To see if it is going to change with a mint drop.)
Control Group- Regular mint.
The pahoehoe<span> flow has a comparatively smooth or "ropy" surface. The surface of the </span>aa<span> flow consists of free chunks of very angular pieces of </span>lava<span>. This </span>difference<span> in form reflects flow dynamics. </span>Aa<span> forms when </span>lava<span> flows rapidly.</span>
The organelle which is used as temporary storage for water, waste products, food, and other cellular material would be the vacuole. It is an organelle found in cells that is <span>within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.</span>
Answer:
2 Smooth yellow : 1 smooth green : 1 wrinkled yellow : 0 wrinkled green
Explanation:
The cross between a true breeding smooth green and a true breeding wrinkled yellow produced a homogeneous smooth yellow F1 . According to Mendel's Law of Dominance, the traits that appeared in the progeny are dominant.
The parents were true breeding, so they are homozygous for all genes.
If the genes are linked, their genotypes can be written as:
smooth green X wrinkled yellow
<h3>
Sy/Sy X sY/sY</h3><h3>
F1: Sy/sY</h3><h3>
</h3>
The F1 is self-fertilized, so a cross Sy/sY x Sy/sY is done. If the genes are very tightly linked, almost no recombination happens between them and all gametes will be parental.
The F1 individuals can produce 2 types of gametes then: <em>Sy </em>and <em>sY</em>.
The expected offspring would be:
- 1 Sy/Sy: Smooth green
- 2 Sy/sY: Smooth yellow
- 1 sY/sY: wrinkled yellow
