Bones contain three components that in itself make it strong and flexible. They are collagen, calcium phosphate, and living bone cells. Collagen gives bones their structure, calcium makes bones strong, and cells generate more bone cells to fill up weakened parts. Calcium intake from food supplements and milk are also good for the bones because it can strengthen them more and make the skeletal system protected from bone irregularities and problems while growing. Vitamin D is essential for the absorption of calcium in bones. In order to offer support to the muscles and tissues of the body, bone growth is very crucial, because a weak bone cannot make the body function well. Comments Report
2. Answer: a. Resulting phenotypes: 100% Yellow.
b. No, there are not blue kernels.
c. All kernels are yellow because the yellow allele (Y) is
dominant over blue allele (y).
Explanation: Crosses a (YY x Yy) and b (YY x yy) result in yellow offspring with genotypes: 1) Dominant homozygote (YY) and 2) Heterozygous (Yy).
4. Answer: a. Genotypes: YY (25%) , Yy (50%) and yy (25%).
b. Phenotypes: Yellow (75%) and blue (25%).
c. There are more blue kernels in the F2 than in the F1.
Explanation: Crosses between F1 members (Yy x Yy) result in yellow and blue offspring with genotypes: 1) Dominant homozygote (YY, 25%) 2) Heterozygous (Yy, 50%) and 3) Recessive homozygote (yy, 25%).
5. Answer: a. Ys and YS
b. YS, yS, Ys, ys.
Explanation: The yellow and smooth individuals with genotype (YYSs) can produce two different gametes: Ys (Yellow and wrinkled) and YS (Yellow and smooth). The yellow and smooth individuals with genotype (YySs) can produce four different gametes: YS (yellow ans smooth), yS (Blue and smooth), Ys (Yellow and wrinkled) and ys (Blue and wrinkled).
this was wrong when i clicked it is traits
Cells get energy by breaking down food molecules to release the stored chemical energy by a process called 'cellular respiration'.
During the process Oxygen is used to oxidize food, that oxidized food is known as glucose.

Answer:
The image of the animal cell was not included in the question, the image has been added as an attachment.
The answer is centrioles; found in animal cells but not plant cells
Explanation:
According to the question, the image in the attachment section is an animal cell with labelled organnelles. An animal cell does not possess a Chloroplast, which is unique to only plant cells. Hence, organnelles D cannot be Chloroplast.
Ribosomes are organnelles made up of a complex of RNA and proteins. They are the site of protein synthesis, which occurs in all living cells. Hence, all cells including plant and animal cells contain Ribosome organnelles. Therefore, it is a wrong choice.
Centrioles are cylindrical tube-like structures made up of microtubules arranged in a specific pattern. Centrioles are present only in animal cells and play a major part in cell division, where they organize microtubules that separate chromosomes. As seen in the image, the two centrioles are perpendicular to one another, forming a CENTROSOME. A plant cell does not possess centrioles instead they contain microtubules organizing centres (MTOC).
Mitochondrion are present in both animal and plant cells as energy-generating organnelles but they are not stacked tubular structures as described in the question.
