Iodine it is an element that is required for the thyroid gland to produce thyroid hormones.
The body does not produce iodine on its own so it needs to come from dietary sources like eggs, prunes bananas, shrimp, cod, etc or you can take supplements of iodine.
When you consume iodine it quickly absorbed and enters into your bloodstream and thenyour thyroid that has tiny cells that capture the circulating iodine and takes in and oxidizes it so it can begin to be used to create (T3) and (T4 which are thyroid hormones.
Answer:
b. the use of DNA as the information storage molecule
Explanation:
Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.
Phototropism as photo means light
eg: photosynthesis
This is a typical case of a dihybrid cross.
From the phenotype of the offspring, we can conclude that the gene for the red color of the flower and the gene for the axial position of the flower are dominant.
Since we know that the ratio of phenotypes in a dihybrid cross of independently inherited alleles is
9(dominant for both traits)
3(dominant for one trait, recessive for the other)
3(dominant for the second trait, recessive for the other)
1(recessive for both traits)
we can expect 3/16 of the f2 generation to be dominamt for one trait and recessive for the other (red, terminal flowers), or to be precise 190 individuals.
<h2>Permanent tissues in Plant</h2>
Explanation:
A) The cell walls of parenchyma cells are thinner than those of sclerenchyma cells
Plants posses basically two kinds of tissue- meristematic tissue and permanent tissue.
Meristematic tissue is made up of cells which are capable of active division and give rise to other tissues,.
Permanent tissue are already differentiated and usually do not divide.
Permanent tissues are -collenchyma, sclerenchyma and parenchyma.
Parenchyma and collenchyma are living whereas sclerenchyma is non-living.
