the results Mendel obtained during his experiments. It showed that if you cross two plants that were true-breeding for different

colors (purple and white), the offspring or first generation (F1) would be ______________ instead of true-breeds, and all were _____________ in color. Interestingly, when he crossed two of these F1 plants, their offspring did not all come out _____________. Instead he obtain a ratio of ______ purple-flowered plant for every ______ white-flowered plant. He concluded that the “heritable factor” for the ____________ trait (white flowers) was not destroyed in the F1 generation. Instead it had been _______________ by the “heritable factor” of the ________________ trait (purple flowers).

Please find the missing answers to the questions in BOLD.

Explanation:

As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.

The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.

Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).

Which structure is common in animal cells but rare in plant cells?
Kobotan [32]

The correct answer is option 3, that is, lysosome.  

The lysosomes comprise hydrolytic enzymes essential for intracellular digestion. They are commonly found in the cells of animals but are rare in plant cells. In the plant cells, the hydrolytic enzymes are most often found in the vacuoles.  

The other mentioned components like cell wall are exclusively found in plant cells, not in animal cells, vacuole is found in both plant and animal cells, it is bigger in plant cells in comparison to animal cells, and the mitochondria are witnessed in both plant and animal cells.

How does the fact that telomeres are long stretches of repeated nucleotides lessen the impact that somatic cells don’t have te
Cloud [144]

Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.

  • Telomeres are repetitive sections at the very ends of chromosomes that are present in a variety of eukaryotic species, including humans and unicellular protists.
  • Each round of DNA replication wears down a little portion of the telomeres, which serve as caps to safeguard the interior chromosomal regions.
  • Most somatic (body) cells do not typically have telomerase activity, but certain adult stem cells and germ cells—the cells that produce sperm and eggs—have.
  • Adult germ cells, tumor cells, and fetal tissues all contain telomerase. Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.

Pls help!!! osmosis help needed!!
galina1969 [7]

Answer:

1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic

Explanation:

1. Given the image, it shows there is 10% glucose outside the cell.

2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)

3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.

2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water <em>outside </em>the cell than in. So, yes, osmosis will occur.

3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).

3. The cell will swell, since water is getting moved in.

6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always <em>swell, </em>as water moves into it.

Hopes this helps!^^ I tried the best I could at explaining.
