Thymine
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Passive Transport: Simple Diffusion
Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. Remember that the cell membrane is a phospholipid bilayer. Although the inside and the outside of a cell are both water-based, there is a hydrophobic region in the middle, and this is an important barrier to anything large, charged, or hydrophilic. Molecules that are hydrophobic, just like the hydrophobic region, can pass through the cell membrane by simple diffusion.
Therefore, simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules from a higher concentration to a lower concentration. Very small molecules can slip through the cell membrane, too, even if they are hydrophilic - just like a few ants might crawl through a crack in the wall just because they're tiny.
Answer;
-Simple cuboidal
Explanation;
-The walls of kidney tubules are formed by simple cuboidal epithelium, which functions in resorbing materials filtered from blood plasma such as nutrients, ions, and water.
-Simple cuboidal epithelium is found in organs that are specialized for secretion, such as salivary glands and thyroid follicles, and those that are specialized for diffusion, such as the kidney tubules.The cells of simple cuboidal epithelium are specialized for diffusion and absorption.
-The cells of this type of tissue can withstand more trauma than simple squamous epithelia and are adapted for diffusion and secretion.
Answer:
some kind of rope that is thick and durable
Explanation:
rope can be used in any situation and can be made sturdy, not to mention it is quite long as well.
Answer: This would affect the whole marine ecosystem. It would also effect the oxygen concentration inside the sea and in outer environment.
It contributes to a huge proportion of oxygen in the environment and if there is some sought of pollution in the sea then the aquatic animals will die and it will effect the other animals present in sea.
The marine ecosystem will be disturbed and the food web inside the sea will also be hampered.
