Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
If a scientist observes an enzyme polypeptide chain arranged in spiral turns that rise upward and are held in place by hydrogen bonds he/she is looking at a tertiary structural arrangement.
Answer:
Hypokalemia
Explanation:
The toxicity due to digoxin increases when metabolic disturbances such as hypokalemia occur. Hypokalemia usually occur during the diuretic therapy and leads to electrolytic disturbances. These disturbances increase the sensitivity of the digoxin to produce toxicity. In such scenarios, even a small concentration of digoxin serum can prove to be toxic. Hypokalemia inhibits the sodium-potassium ATPase and even treatment with antibodies specific to digoxin can lead to hypokalemia
Answer:
The correct answer is option b) "the number of chemical bonds between the molecules".
Explanation:
Chemical bonds are the forces that enable the formation of compounds. The number of chemical bonds is a determining factor to know if an interaction will be transient of stable. The more chemical bonds the more stable an interaction will be. Few chemical bonds between molecules makes an interaction unstable and easy to break, enabling transient interactions that are key to certain biological pathways.
Answer:
Water
Oxygen
Carbon dioxide
Lipids
Explanation:
The plasma membrane is a lipid bilayer with a hydrophobic core made of nonpolar tails of phospholipids. The plasma membrane allows only uncharged, small and hydrophobic substances to pass through it. Charged particles such as ions, polar molecules such as sucrose can not cross the hydrophobic core of the plasma membrane.
Oxygen and carbon dioxide gases have small sizes and can diffuse through the spaces between the tails of phospholipids of lipid bilayer of the plasma membrane without any transport proteins. Lipids are hydrophobic and therefore, do not need any transport proteins to cross the lipid bilayer. The small water molecules are also free to move through the membrane.
