Answer:
1) RR x rr
2) Shown below
3) 100% Rr with red eyes
4) Punnett square shown (Rr x Rr)
5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Explanation:
Let's say the allele for red eyes is R and the allele for brown eyes is r.
1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr
2. R R
r <em>Rr Rr</em>
r <em>Rr Rr</em>
<em />
The F1 generation is shown in the Punnett square above.
3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes
4. A cross between the F1 generation (Rr x Rr) gives the F2 generation
R r
R <em>RR Rr</em>
r <em>Rr rr</em>
<em />
5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Answer:
The correct answer will be - in the bacterial cells
Explanation:
The complexity of life began on Earth when the simple amoeba-like organism started ingesting the bacterial cells. The ingestion of the aerobic respiration performing bacteria formed the mitochondria and ingestion of the photosynthetic bacteria formed the chloroplast of the cell. The bacteria while evolution lost their identity and now cannot live without the host cell.
This hypothesis was supported by the evidence like a comparison of the Ribosomes of this organelle is similar to the prokaryotic bacteria as the bacterial cell.
Thus, in the bacterial cells is the correct answer.
Cuz they loved each other.
Proteins are considered as building blocks of the body, from structure, enzymes, transport of small molecules, hormones, and other bodily functions. People may have thought that these proteins are responsible for passing traits from generation to generation because there is evidence of function. For instance, a person with sickle cell anemia (problem with the protein hemoglobin) passes the trait to his child. Scientists back then hypothesized that proteins are responsible for heredity. But further research holds that untrue. First, proteins are complex and bulky molecules that has specific functions and a misplaced or deleted amino acid (amino acids are the basic units of proteins) may affect the function drastically. Having them be passed from one generation to another may produce an error in the amino acid sequence and therefore the function. Second, the entire number of proteins in the body are almost innumerable to be contained in one cell and determine functions. So the idea is that, there must be a molecule, with a structure simple enough to code for proteins, compact enough to fit in the cells' nuclei, and reselient to damage, hence DNA.
