Answer:
pleura
Explanation:
Thin layer of tissue that protects the lungs
Answer:
behavioral separation
Explanation:
The separation leading to the speciation of the two groups of killer whales would be considered a behavioral separation.
<em>Behavioral separation or isolation is a form of separation that occurs between two groups of individuals (that use to be of the same group) as a result of preference for a particular behavior or set of behaviors.</em>
The preference for the behavior eventually leads to the two groups becoming separate species, a form of speciation known as sympatric speciation.
<span>Gram-negative bacteria have a cell wall that is <u>thin</u> and does not accept the stain, making it appear <u>red or pink</u><u />.
<u>
</u>Gram staining is used for differentiation gram-positive from gram-negative bacteria based on the characteristic of their cell wall. Gram-negative bacteria have a thinner cell wall than gram-positive bacteria. In this staining, bacteria are first stained with crystal violet dye. Only gram-positive bacteria will be violet colored because they can retain the dye thanks to their cell wall. The second staining with fuchsine or safranin will give the red or pink color to the gram-negative bacteria. <u>

Answer: The correct answer is OSMOSIS.
Explanation:
The option attached to this question are as follows:
A. Filtration.
B. Osmosis.
C. Active transport.
D. Co-transport with sodium ion.
Water re-absorption is the process by which water, which was lost during glomerular filtration re-enter the blood. The process typically occurs at the proximal convoluted tubule of the nephron. The process occurs by mean of osmosis, which is a form of passive transport. Re-abosorption usually occur based on the concentration gradients that exist in the convoluted tubule, movement takes place from the high concentration in the tubule to the low concentration in the blood capillaries that are surrounding the tubules.
