Answer:
8+5 = x - 7
Explanation:
a number is X
sum means addition
difference means subtraction
To solve: You need to isolate x on one side of the equation (one side of the = sign). To do this, add 7 to both sides so you can move it from one side to the other:
8 + 5 = x - 7
+7 +7
As you can see, adding 7 will cancel out the - 7 on the right side, and move it to the left. Now the equation you are left with is
8 + 5 + 7 = x
Finally add the numbers together and you will get your value for x.
8 + 5 + 7 = 20
20 = x
Plants respond to light in a process called phototropism.
Answer:
3/4
Explanation:
If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.
<h3><u>Gene A</u></h3>
AA x Aa
- F1 genotypes: 1/2 AA, 1/2 Aa
- F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>
BB x bb
- F1 genotypes: 1 Bb
- F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>
Cc x Cc
- F1 genotypes: 1/4 CC, 2/4 Cc, 1/4 cc
- F1 phenotypes: 3/4 C, 1/4 cc
We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:
<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>
