Answer:
12 : 3 : 1
Explanation:
According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and 1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.
<em>Dihybrid cross for heterozygous summer squash:</em>
WG Wg wG wg
WG WWGG WWGg WwGG WwGg
Wg WWGg WWgg WwGg Wwgg
wG WwGG WwGg wwGG wwGg
wg WwGg Wwgg wwGg wwgg
Genotypes:
W-G- and W- gg = white = 12
ww G- = yellow = 3
ww gg = green = 1
Answer:
This is refers to as Greenstick fracture.
Explanation:
This is the type of fracture common in children less than 10 years, in which there is incomplete fracture of the bone,with ,but the cortex remain flexed.It is called green stick because it is analogous to the act of breaking a branch of a tree, which is not completely broken, from the main branch.
It is usually to due to falls,and common in kids because of their soft bones which is not completely formed and therefore will not break off completely like that of adults when fractured, but only from one side only.
<span>The synthesis of proteins takes two
steps: transcription and translation. Transcription takes the
information encoded in DNA and encodes it into mRNA, which heads out of
the cell's nucleus and into the cytoplasm. During translation, the mRNA
works with a ribosome and tRNA to synthesize proteins.</span>

Answer:
The correct answer is " two cardiac muscle cells are connected by gap junctions".
Explanation:
Intercalated discs are microscopic features seen in the microscope as cardiac fibers, found between the myocardial cells of the heart. These features correspond of two cardiac muscle cells connected by gap junctions. The intercalated discs allow the interconnection of multiple cardiac cell muscles to work simultaneously as a single functional organ or syncytium.
