Thomas Malthus was economist who proposed that human populations grow faster than the resources they depend on which becomes limiting factor for them, causing the increase of populations but also increase of famine and diseases. As a consequence, the weakest members die. Darwin linked this with the “survival of the fittest" (naturals elections favors the best suited for reproduction and survival).

Georges Cuvier was anti-evolutionist and religious man, but he did have influence on Darwin theory of evolution (natural selection). He was against linear system of classification so, his believes that there is more than one lineage for species helped Darwin shaped his theory.

Charles Lyell geologists who believed that geologic processes that were at the beginning of time were the same ones that were happening at the current time (processes work the same way through time). He explained that slow changes built up over time, so Darwin linked that with the way that life on Earth changes. (small adaptations that accumulated over long periods of time change a species).

If a double foul occurs during a down in which time expires, the period is ended
Zina [86]
This statement is false.

Double fouls are when two players on opposing teams commit a foul, which makes the fouls of the players "cancel out" and ball possession does not change. However, personal fouls are still charged on both of the offending players.

Biologic agents differ from other injurious agents in that they are able to replicate and can continue to produce their injuriou
Nostrana [21]

The question is incomplete as it does not have the options which are:

A. Gram-negative bacilli cannot cause harm to the cell; only Gram-positive bacilli can harm the cell.

B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.

C. Gram-negative bacilli excrete elaborate exotoxins that interfere with cellular production of ATP.

D. Gram-negative bacilli enter the cell and disrupt its ability to replicate.

Answer:

B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.

Explanation:

Gram-negative bacteria are pathogenic in nature due to the composition of their cell wall. Their cell wall contains an additional layer of a molecule called lipopolysaccharides or LPS.

The LPS layer is toxic in nature and is known as endotoxin and is involved in the pathogenicity of the bacteria as the toxin causes the injury to the Endothelial cell membrane of the host cell.  

When the bacteria cell is lysed and the LPS circulates in the blood, then LPS binds the receptors and acts on CD14. This attracts the neutrophils at the site and can cause vascular injury due to increased capillary permeability.

Thus, Option-B is the correct answer.
