What organelle is missing from the red blood cells?

taurus [48]

Answer:

The correct answer is - they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria

Explanation:

Red blood cells are considered as the cells, carry oxygen with the help of hemoglobin protein present in it to the various parts of the body from the lungs and carry CO2 back to the lungs.

These cells are different from the normal cell as they do not participate in the protein synthesis due to the fact that they lack various cell organelle and cell components required. Nucleus and DNA are major components or organelle missing from these cells. In addition to these two, endoplasmic reticulum and mitochondria also missing from RBCs.

What are 5 examples of coevolution from the movie Evolutionary Arms Race?

Step2247 [10]

Answer:

1. The adaptation of the garter snake to the increasing toxicity of the rough-skin newt

2. The development of antibiotic-resistance by the tuberculosis bacteria in prisoners in Russian prisons

3. The development of FIV-resistance in wildcats

4. The immunity to HIV in about 10% of caucasians due to mutations in their cells that occured among those who survived the Black Death.

5. The development of immunity to asthma in children exposed to livestock at an early age in Bavaria

Explanation:

Coevolution refers to the the evolution that occurs in two species of organisms due to the mutual interaction or interdependence of the two species. Due to this interaction among species, a change in one organism results in adaptive changes in the other organism as well.

Coevolution can occur is any of these relationships between organisms: predator-prey, mutualism, or commensalism.

In the movie, Evolutionary arms race, the following examples of coevolution were highlighted:

1. The adaptation of the garter snake to the increasing toxicity of the rough-skin newt.

2. The development of antibiotic-resistance by the tuberculosis bacteria in prisoners in Russian prisons.

3. The development of FIV-resistance in wildcats.

4. The immunity to HIV in about 10% of caucasians due to mutations in their cells that occured among those who survived the Black Death.

5. The development of immunity to asthma in children exposed to livestock at an early age in Bavaria.

What is the resistance of a 20-cm-long column of blood in this artery? assume that resistivity of blood is equal to 1.6 ωm.

Alinara [238K]

The way in which you need to solve this is by using the formula:
R = ρL/A
That one is the formula that demonstrates Resistance of a wire in Ω.
The formula can be explained like this:
ρ is resistivity of the material in Ω-m 
L is length in meters 
A is cross-sectional area in m² 
A = πr², r is radius of wire in m
As soon as you have your numbers, you can replace and proceed to get the asnwer
