<span>D. Eukaryotic cells have true nuclei.</span>
A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. Both plant and animal cells are eukaryotic cells.
Coelom: fluid-filled body cavity lined with mesoderm
or coelomates: fluid-filled body cavity completely lined with cells from the mesoderm that separates digestive tract from the outer body wall, two openings for digestive system
The third stage of mitosis is anaphase.
Answer:
The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Explanation:
the fundamental problem that an aquatic animals face during its progress to land to save the egg or embryo from parching. So they have developed cleidoic eggs where undeveloped organism stay implanted inside extra embryonic layers, for example, amnions and are secured in egg shells. These eggs have minute pores so embryo can make gas exchange.
This egg shells forestall water misfortune. Interior treatment, however are available in certain sharks, yet it is for the most part a variation of land creatures. Explicit intromittent organs have been created for moving of sperm in to female. In contrast with water , gaseous movement is in land creatures is happen through advancement of lungs which contain numerous alveoli where gaseous exchange is occurred. Decreased surface to volume ratio decrease productivity of gas exchange , not increment.
Thus, The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Chemical energy it is the energy stored in the chemical bonds of molecules
