Which of the following is true of red blood cells? A. They live for only 120 days. B. They have multiple Nuclei. C. They live for only about 20 days. D. Once created in bone marrow, they circulate for our lifetime.

Answers

Answer 1
correct answer is (D. Once created in bone marrow, they circulate for our lifetime)
Answer 2

A. They live for only 120 days is correct. They are created in the bone marrow and destroyed in the spleen "red blood cells graveyard"

B. They have multiple Nuclei. Red blood cells don't have a nucleus but some can present structures called Jolly's bodies that are small pieces of the nucleus that they lost in the differentiation process

C. They only live for only about 20 days. No, red blood cells live for about 120 days

D. Once created in bone marrow, they circulate for our lifetime. Again, they have a limited lifetime

1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the  entire year, and this explains its warm climate.

2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.

3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.

4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.

Answers

Answer:

Explanation:

We present an explicit and simple approximation for the superadiabatic excess (over ideal gas) free power functional, admitting the study of the nonequilibrium dynamics of overdamped Brownian many-body systems. The functional depends on the local velocity gradient and is systematically obtained from treating the microscopic stress distribution as a conjugate field. The resulting superadiabatic forces are beyond dynamical density functional theory and are of a viscous nature. Their high accuracy is demonstrated by comparison to simulation results.

Two thirds x is equal to four sixths x.

4/6x-1/2=1/3+5/6x

Subtract 4/6x from both sides.

-1/2=1/3+1/6x

Make sure -1/2 and 1/3 have a common denominator before subtracting 1/3 from both sides.

-3/6=1/3+1/6x

Which is not a benefit of maintaining sustainable forest ecosystems?
Select one:
O a. Empty space on which to build homes
b. Habitat for thousands of species
c. Reduction of erosion in watersheds

Answers

The correct answer as to which is not a benefit of maintaining sustainable forest ecosystems would be empty spaces on which to build homes.

An ecosystem refers to a network of communities interacting together as a unit. A forest ecosystem, therefore, is a community of different plants, animals, and microbes interacting together and with their physical environment as a unit.Sustainable forest ecosystem is a system of managing forest resources in such a way that the ecological processes and functions provided by the forest do not depreciate. The ecological functions of forest ecosystems include the provision of foods, drugs, and raw materials for man, protection of watersheds,  provision of habitats for other species, and playing important roles in the stability of climates.

Hence, not maintaining forest ecosystems in a sustainable way means that some of the functions they perform such as the provision of habitats for species and reduction of erosion in watersheds would be lost.

The only option that is not a benefit of maintaining sustainable forest ecosystems is A.
