Answer:
Iodine, or more accurately iodide (I-), is avidly taken up from blood by thyroid epithelial cells, which have on their outer plasma membrane a sodium-iodide symporter or "iodine trap". Once inside the cell, iodide is transported into the lumen of the follicle along with thyroglobulin.

Answer:
So, there are 3 parts that explain the answer to your question.
Explanation:
Part A-
The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.
Part B-
The two fish are of the same species because they can mate with each other. Also, the characteristics of the blind cave fish enable them to live in caves. Eyes need energy. So, developing bodies with no eyes allowed these fish to function more efficiently.
Part C-
The two types of fish developed different traits within their respective habitats. However, as a species, they have some genetic diversity because these populations have different genes between them.
Answer:
All
Explanation:
All of them are characteristic of eukaryote
Answer:
Option C
Explanation:
The cyanobacteria is the oldest life form that once existed on planet earth some 3.7 billion years ago. These cyanobacteria formed layered structures fossils which are called as stromatolites
Hence, stromatolites are the fossilized colonies of cyanobacteria.
A set of rocks in Greenland show the evidence of cyanobacteria as a living organism.
These stromatolites have layered structure of bio-chemical accretionary that are produced by trapping sedimentary grains through biofilms of microorganisms such as cyanobacteria.
Hence, option C is correct
Through meiosis, diploid parents produce haploid cells called gametes. The gametes, through sexual reproduction, then meet and join into one cell called a zygote that is diploid.
The zygote then develops into a diploid organism with genetic traits from both parents.
