What is the unique structural modification in lymphatic capillaries that increases their permeability?

Biology
1 answer:
KonstantinChe [14]3 years ago
7 0

Answer:

Minivalves

Explanation:

Lymphatic capillaries are so much permeable that some researchers thought that they are open from one side but scientists found that this permeability is due to some structural modification.

The endothelial cell that forms the lymphatic capillaries wall are not packed tightly and overlap each other very loosely which makes easy openings in the structure called mini valves.

When the pressure of fluid in interstitial space is high then the mini valves become open and allow the fluid to enter the lymphatic capillary. So mini valves are the unique structural modification that increases permeability in lymphatic capillaries.

Which statement is NOT correct?
aliina [53]

Answer: a. Heritability research is able to identify genes for particular behavior patterns.

Explanation:

Heritability is the ability of a trait to move from one generation to another. Heritability, sum of phenotypic (observable) variability that is due to human genetic variations in a population.

Heritability, in a general sense, is the ratio of variability for a trait or character in a population due to variations between genotypes and the overall phenotypic variation.

Hence, as genes identification is are the basis of heritability research, option "a" is incorrect.

What allows scientists to predict future climate change with some sense of accuracy?
iren [92.7K]

Answer:

Climate models can show the composition of the atmosphere in the future.

Explanation:

Climate models help predict how the average conditions will change in a region and they also serve as an extension of weather forecasting. They are quite broad and can make analysis and predictions over long time spans.

These models are generated from some set of mathematical principles with different data points numbering over a thousand. These large data points help increase the accuracy of the models.
