<span>This behavior is an example of B. overproduction. The frog lays thousands of eggs, which is much more than it needs, or would need in perfect conditions. However, most of those eggs doesn't survive, and little frogs are never born in that case. This is why it has to have a lot of eggs so as to ensure that a decent number of offspring survives so as to continue the species.</span>
The human egg cell is the largest cell in the human body, measuring approximately 0.13 mm in diameter.
Its size is 10 times the diameter and 1000 times the volume of most other human body cells. It can actually be seen without the aid of a microscope if one observes keenly.
Unlike ordinary body cells which have a cell membrane, the egg has a special outer coat called zona pellucida which is made up of a jelly-like extracellular matrix composed mainly of glycoproteins.
Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.
Explanation:
Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc
From the examples given, the cells of multicellular organisms are specialized in function in that:
- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces
On the other hand, unicellular organisms possess just one cell that do all the functions.
Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.
