Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as they are placed within the rib cages. The lungs actually consists of elastic sacs that contract and expand for taking in and releasing air. This way oxygen is passed into the blood and carbon dioxide is taken out from the blood and passed out. This is also the main function of the lungs.

Answer:

The given statement is true.

At lungs level, trachea segmented into two primary bronchi: left primary bronchus which enters the left lung and right primary bronchus which enters the right lung.

In each lung, primary bronchi (both left and right) segmented into tertiary bronchi via secondary bronchi.

Tertiary bronchi divide to form smaller airways termed as bronchioles.

These bronchioles eventually connect with alveoli, specialized sac-like structures which form the site for gas exchange.

Thus, we can conclude that each lung is fed oxygen by a separate bronchus.

Which information is needed to construct a geomagnetic time scale?
AleksAgata [21]

Answer:

the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth

Explanation:

The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.

During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.

To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.

An oil spill happened at the Wild Harbor salt marsh on Cape Cod, Massachusetts in 1969. The oil has persisted in the ground sinc
Dima020 [189]
I would guess that the answer would be :'<span>These organisms dig more shallow burrows than they used to.</span>' If the crabs actively dig burrows, as many crab species do, and a layer of oil has persisted in the lower soil strata, it makes sense that the crabs would be reducing the depths of their burrows to avoid contact with the oil. The other possibility is that the crabs might might migrate to deeper waters, but this is less likely because the crabs would be evolved to utilise the intertidal zone.
