Answer:

D) the frequency of rainfall needed for the germination of desert plant seeds

Explanation:

When we talk about abiotic factors, we refer to the non-living factors. The abiotic components of an ecosystem include: Water, air, temperature, light, and the like.

So if we consider it as a limiting factor to population size, this should be the cause of the limitation.

Among all the choices, only D, shows an abiotic factor being the cause of population limiting. Rainfall is an abiotic factor (water), which influences the germination of desert plant seeds, specifically, it depends on the frequency of rainfall.

American vultures used to be classified in the same family as African vultures. Which discovery caused scientists to reclassify
Mashutka [201]

Answer:

DNA evidence revealed the American vultures share more recent ancestor with the Storks

Explanation:

The hooded vultures that is mostly found in the African continent have a close resemblance with the American vultures and were traditionally classified to belong to the Falcon family.

However, it was observed that the American vultures shared a similar behavior with Stork which is not common to the vulture found in Africa, including the hooded vulture. The Stork and the American vulture exhibit the behavior of urinating on their legs when being overheated. When the urine gets evaporated, it helps them to cool their body temperature.

This shared behavior between the storks and the American vultures led scientists into using molecular analysis in analyzing the DNA of the hooded vultures found in Africa, the American vultures, and the stork.

Evidence from the DNA analysis later revealed that the American vultures and the storks share a more common DNA sequences than African vultures and American vultures do.

fiasKO [112]
A baby's immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus's immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
