How does the shape of the red blood allow diffusion to occur efficiently

Biology
2 answers:
grin007 [14]2 years ago
3 0

Answer:

The partial pressure of oxygen determines the affinity of hemoglobin for oxygen. Red blood cells have the shape of a flattened disk, generating a broad surface area for the diffusion of oxygen. Since their only purpose is carrying oxygen throughout the body, they lack many typical cell structures, including a nucleus.

Answer:

* Because of their viscoelastic characteristic, red blood cells are able to squeeze through very thin capillaries in order to deliver oxygen and remove carbon dioxide. * The biconcave shape of red blood cells helps maximize the overall surface area required for oxygen absorption.

Once collected, lymph ultimately drains into __________.
Natasha2012 [34]
<span>Once collected, lymph ultimately drains into venous circulation.
<u />Lymph goes from terminal lymphatic ducts into venous circulation through the subclavian veins.
Lymph is not filtered or detoxicated yet at this point, and it doesn't go to arterial circulation because that would just distribute it all over the body, instead of just the heart.

Analysis of stable carbon isotopes in ________ can provide information on ancient diet.
tino4ka555 [31]
<span>The answer is bone. A new technique of observing Harris lines (between the diaphysis and epiphysis of long bones), by use of radiography, of bone is being used to postulate ancient diet of populations. This is especially used to determine stressful periods that were characterized by poor diet (deficiencies) by comparing carbon and nitrogen isotope ratios</span>

The Manx cat has abnormal spinal development and no tail. The mutation is a dominant allele (M). For notation purposes, m refers
lord [1]

Answer:

d. 1/3

Explanation:

Given, M is a dominant allele which is responsible for tailless kittens and m is recessive wild type allele which leads to kittens with tail. M is a lethal allele which means that if it is present in homozygous condition, the kitten will not survive. So the Manx cats should be heterozygous i.e. Mm.

When they mate, Mm X Mm :

      M        m

M   MM    Mm

m   Mm    mm

1/4 kittens will have MM genotype so they will not survive. Out of the remaining kittens, 1/3 will be mm and hence they will have normal tail. Remaining 2/3 will have Mm genotype like their parents and will be born without tail. Hence, there is 1/3 probability that one of the four kittens will have a normal tail.
