Answer:
a = 9
Explanation:
5(a + 4) - 6a + 1 = 12
5a + 20 - 6a + 1 = 12
5a - 6a + 20 + 1 = 12
-1a + 21 = 12
-21 -21
--------------------------------
-1a = -9
/-1 /-1
---------------------------------
a = 9
Given what we know, we can confirm that the statement in the question is in fact true, by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram.
<h3>What else do we know about the
embryo in this time frame?</h3>
During the first eight weeks, the embryo undergoes many changes. At this time:
- The legs and arms have formed.
- The fingers and toes are beginning to develop.
- It begins to be called a fetus.
- It is developing the lungs and lymphatic system.
- and much more.
Therefore, we can confirm that the statement that by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram, is in fact true.

Answer:
"T" X "t" yields offspring that are all heterozygous with genotype "Tt"
Explanation:
An Allele refers to either of a pair of contrasting genes.
So, "TT" being the same yeild just one allele (T), while "tt" also yield one allele (t)
So, the cross of the both alleles
"T" X "t"
yields offspring that are all heterozygous with genotype "Tt"
Thus, the crossing dominant tall plant height "TT" and recessive short plant height "tt" yielded heterozygous tall plants "Tt"
