In regions of the cardiovascular system where there is steady laminar blood flow, the shear stress on cells lining the walls of

the blood vessels is about 20 dyne/cm2. If the shear strain is about 0.008, estimate the shear modulus for the affected cells. Note 1 dyne = 1 g ⋅ cm / s 2 and 1 N = 10 5 dyne

Answer:

250 N/m2

Explanation:

Shear stress on cells lining the walls of the blood vessels  is equal to 2020 dyne/cm2

In terms of Newton/square meter, shear stress is equal to

20*\frac{dyne}{cm^2}  (\frac{10^{-5}N}{1 dyne} )*(\frac{1 cm^2}{10^{-4}*m^2} )\\= 2.0 N/m2

Shear modulus is equal to shear stress divided by shear strain

Thus, shear modulus is equal to

= \frac{2.0}{0.008} \\= 250N/m2

How much of the sun's energy is reflected back into space?
AnnyKZ [126]
All of my scores say it's 29 to thirty, which is the correct answer, so I'm afraid I don't know, my suggestion here would be to go with 20, because if it was forty then we would surely be dead. <span />

Which of the following statements correctly describes how Mendel accounted for the observation that traits had disappeared in th
Genrish500 [490]

Answer:

A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.

Explanation:

Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.

When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.

What is the biggest difference when comparing a prokaryotic and a eukaryotic cell?
tatuchka [14]

Answer:

Well, the primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.
