I'm assuming this is the same image that was posted before, therefore the answer is "gene flow" which occurs through population groups by natural selection and other factors.
<span>Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Use forceps to hold the skin away from the muscle while you cut, if necessary. Make horizontal incisions just above the legs and just below the arms, then fold the resulting flaps back and pin them. (You may need to use a scalpel to help separate the skin from the muscle underneath as you fold it back.)Repeat the incisions as before, this time cutting through the muscle layer to a point just below the arms. Lift the muscle with the forceps to prevent cutting the organs underneath.When you reach the area just below the arms, turn your scissors and make horizontal cuts through the hard sternum. Repeat the horizontal cuts just above the arms, and then remove the bony strips entirely. Pin the remaining muscle flaps back, just as with the skin.<span>Look into the body cavity. The yellow finger-like projections on the sides are the fat bodies. It may be necessary to remove some of these in order to see the organs clearly. Likewise, a female specimen may have well-developed eggs filling the body cavity and obscuring the organs. Remove them as necessary.</span></span>
Answer:
Steroid; is a component of eukaryotic membranes.
Explanation:
Cholesterol is one of the most important chemical synthesized by all the animals. The chemical formula of cholesterol is C27H46O. The cholesterol in solid state was first given by C27H46O.
Cholesterol is present in the plasma membrane and maintain its membrane fluidity. Cholesterol is an important structure of the plasma membrane and acts as a pre cursor for various hormone. The cholesterol is a type of sterol and a lipid.
Thus, the correct answer is option (1).
Ionic bonding?
the bonding between non-metals and metals
non-metals form negative ions, so they are attracted to metals, which form postive ions
Answer: A.They contain plants that purify water.
