The representation of the genotypes is as follows:
Homozygous dominant for curly hair (James): CC
Heterozygous dominant for curly hair (wife): Cc
The curly or straight hairs are the phenotypes and CC or Cc is the genotype of parental alleles.
When the first child is born which means the F1 generation, the type of hair the child will have can be predicted by punnet squares.
The Punnet squares have been shown in the image.
From the above punnet squares, two out of four probable phenotype or genotype of curly hair is 2/4 = 1/2 or 50%, have CC as their genotype and are homozygous dominant for curly hairs.

Tangerines AmbitiousThere are a few hundred billion stars in our galaxy, the Milky Way and billions of galaxies in the Universe. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns. Astronomers do this with stars.
So far we have discussed the luminosity and colour or effective temperature of stars. These can be plotted to form what is one of the most useful plots for stellar astronomy, the Hertzsprung-Russell (or H-R) diagram. It is named after the Danish and American astronomers who independently developed versions of the diagram in the early Twentieth Century.
In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis. This can be expressed as a ratio of the star's luminosity to that of the Sun; L*/Lsun. Astronomers also use the historical concept of magnitude as a measure of a star's luminosity. Absolute magnitude is simply a measure of how bright a star would appear if 10 parsecs distant and thus allows stars to be simply compared. Just to confuse things, the lower or more negative the magnitude, the brighter the star. By definition a star of magnitude 1 is 100 × brighter than one of magnitude 6. Our Sun has an absolute magnitude of + 4.8.

Answer:
DNA never leaves the nucleus; RNA is in the nucleus and in the cytoplasm.
Explanation:
DNA and RNA differ from each other with respect to their structure, function, and location. DNA is always present in the nucleus and never leaves the nucleus.
DNA replication and transcription also occur in the nucleus to form DNA and RNA respectively.
On the other hand, RNA is present in both the nucleus and cytoplasm. The mRNA leaves the nucleus and enters the cytoplasm to serve as a template in protein synthesis. The rRNA and tRNA are also present in the cytoplasm.
Answer:
c. Proteins and lipids are made on the ER membrane and put in vesicles.
a. Vesicles containing proteins and lipids fuse with the Golgi bodies.
d. The Golgi bodies tag the molecules to signal their ultimate delivery.
b. Vesicles pinched off from the cristernae carry the molecule to its location.
Explanation:
Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
