Which of the following increases the strength of the hydrophobic interactions in lipid bilayers, and thus makes them less permea
jenyasd209 [6]

Answer:

Option (C).

Explanation:

The plasma membrane of the eukaryotes are made of the phospholipid bilayer and the proteins are embedded or span the membrane bilayer. The carbohydrates are attached in moieties with the protein and lipid.

The fluidity of the membrane depends on the saturation, cholestrol and the hydrocarbon chains. The hydrocarbon chain is non polar in nature that allows the diffusion of non polar solutes across the membrane. This decreases the permeability of the polar molecules and the hydrophobic interactions in the membrane.

Thus, the correct answer is option (C).

Plants and animals die without air. Why? Which gases do plants and animals inhale and exhale? What are the role of these gases i
Papessa [141]

Answer:

Plants and animals both are living organisms that are directly dependent on the air. The air is comprised of various gases with definite proportions such as  78% of nitrogen, 21% of O₂, 0.9% of argon, 0.03% of CO₂, and other minor gases.

Oxygen (O₂) is the main gas that is essential for life to exist. Without this gas, no organisms can survive.

The organisms inhale oxygen (O₂) gas and exhale carbon dioxide (CO₂) gas.

These gases play an important role in the lives of plants and animals as it helps in carrying out the process of respiration. This process is essential in order to generate energy in the body of the organisms where the food particles (commonly known as sugar) are disintegrated by the cells. This is how an organism respire by inhaling O₂ gas and exhaling CO₂ gas.

What aspect of chromosome behavior most clearly accounts for mendel's law of independent assortment?
makkiz [27]
The aspect of chromosome behavior that most clearly accounts for Mendel's Law of Independent Assortment is the replication of chromosomes. The replication occurs before meiosis. As a result, the alleles of one gene can be sorted into gametes and are independent of the alleles of other genes.

According to carl rogers, the ________ is how people see their actual traits and abilities.
masha68 [24]

According to Carl Rogers, the <u>real self</u> is how people see their actual traits and abilities.

  • The Real Self and the Ideal Self make up the personality, according to humanistic psychologist Carl Rogers.
  • They are words that are used to characterize a person's personality facets. The true talents, aptitudes, preferences, and attributes of an individual are reflected in one's real self.
  • The ideal self and the real self were further split by Rogers into two groups.
  • The difference between your real self and your ideal self is that the latter is the person you truly are. Rogers emphasized the requirement for consistency between these two selves.
  • For example, your ideal self might be someone who spends a lot of time learning, does well in science topics, and is not sickened by the sight of blood. If your Real Self differs significantly from this idealized version, you may feel unsatisfied with your life and like a failure.
