Answer:
c. The ratio of long to short fatty acid tails in the membrane phospholipids increases
e. There is an increase in the saturation state of the fatty acid tails of membrane phospholipids
Explanation:
In biological lipid membranes, the homeoviscosity refers to the process by which the membrane 'adapts' its lipid composition to maintain a proper fluidity. It is well known that the membrane's fluidity increases with increasing temperatures. In this regard, it is important to have into account two points. First, the length of the fatty acid tail alters the membrane's fluidity: shorter fatty acid tails increase fluidity, while longer fatty acid tails decrease it (because shorter tails establish fewer molecular interactions between fatty acids tails). Second, the degree of saturation (i.e., the number of bonds between the carbon atoms) of fatty acids tails also affects homeoviscosity. A higher saturated fatty acid content decreases the membrane's fluidity because saturated tails are arranged in order to maximize molecular interactions between fatty acids tails.
It can last from 1 to 4 hours
Answer:
The oxygen molecule passes through the wall of the alveoli and enters inside tiny blood vessels called capillaries where exchange occurs. A protein called hemoglobin in the red blood cells then carries the oxygen around your body.
Explanation:
Answer:
So that we can identify them in the same species.
Explanation:
Many animals have similar species but different genus.
B. It has a whip, like a tail
Explanation - Protists are unicellular organisms. Some multi-cellular organism might exist. Some protists have silica plated scales on their body surface like diatomaceous earth. They exhibit both type of respiration - aerobic and anaerobic. They mainly have parasitic mode of nutrition.
Protists also have flagella which they whip that in turn helps in their movement and this feature have made them to enter into the water body, example - euglena. Paramoecium have cilia on their entire surface that helps in their locomotion in water.
