What specializations are common in the digestive tract of higher organisms such as humans?

Biology
1 answer:
luda_lava [24]2 years ago
5 0

 One is the presence of villi and microvilli in the small intestines that increase the surface area for which food is absorbed. Second is the presence of goblet cells that secrete mucus to prevent self-digestion of the tract lining. Another is the specialized enzymes in different regions of the digestive tract that specialize in digesting particular foods.

As children get older, cultural influences on behavior become much stronger; and as a result, it becomes difficult, if not impos
DanielleElmas [232]

Answer:

False

Explanation:

Sex is a biological term and gender is depended on the roles performed by an individual. In our society it is mandatory for a man or woman to behave and develop sexual preference for its opposite gender and this conservative thought process had strongly held the base of defining a sexual acts which is intended to happen between a male and female only.

However, this is not something defined by nature but by individual likeliness. This is the reason why even after being a male by sex, a male by gender can have likeliness for another male. This is something which cannot be bounded by social and cultural belief even after being into it for years.

Hence, the given statement is false

gHow would an inhibitor of cAMP phosphodiesterase affect glucose mobilization in muscle? It would reduce cAMP levels and inhibit
Ksivusya [100]
<h2>cAMP and glucose mobilization</h2>

Explanation:

It would maintain high cAMP level and elevate glucose mobilization

  • Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
  • Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
  • As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it
  • Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
  • In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood

Why do methane is a gas at room temperature and water is a liquid, even though both molecules are similar in size and mass?
emmainna [20.7K]

Answer:

Water can hydrogen bond.

Explanation:

Liquids become gases once they are heated to a certain temperature. Heat is a form of energy. This change occurs when the intermolecular forces between the liquid molecules are energized enough to break. This breakage is necessary because gaseous molecules exist individually and do not interact with one another. That being said, it takes more heat to boil water because its intermolecular forces are stronger than methanes.

Intermolecular forces (IMF) are a result of partial charges on the molecular atoms that cause temporary bonds to form between molecules.

Methane is a nonpolar molecule, meaning each atom can only have slight partial charges. The strongest IMF methane participates in are London Dispersion Forces.

Water, however, is a polar molecule, with the hydrogens having strong partial positive charges and the oxygens having strong partial negative charges. This allows water to participate in a very strong IMF called hydrogen bonding. Again, because these partial charges are so strong, the water molecules can form stronger IMFs.

<u>*When molecules have stronger IMFs, they require more energy(heat) to overcome them.*</u>
