Energy would be passed from the deer to the wolf if the grasses had 5000 kcal is 50kcal.

50kcal Energy would be passed from the deer to the wolf if the grasses had 5000 kcal.

According to 10% Energy law given by Lindmann, only 10% of energy is transferred to the lower level to the higher level.

According to the given question,

Grass = 5000kcal

This indicates only 10% energy will be transferred from Grass to Deer according to the law.

Deer = 10% of 5000kcal = 500kcal

This indicates only 10% energy will be transferred from Deer to Wolf according to the law.

Wolf = 10% of 500kcal = 50kcal

The rest energy is lost in the Respiration and only 10% gets transferred.

So, Energy would be passed from the deer to the wolf if the grasses had 5000 kcal is 50kcal.

Superantigens cause the stimulation of T cells to overproduce cytokines.

Some pathogens in an unusual way take over the immune system and mislead it by interfering in the adaptive immune system.
Instead of processing by APC (Antigen Presenting Cells), superantigen is directly bonded to MHC-II (Major histocompatibility complex) and TCR (T cell receptor) for a longer period than normal.
As a result, about 20% of T cells are stimulated to produce cytokines such as interleukin-2 (IL-2), interferon-γ (INF-γ), and tumor necrosis factor α (TNF-α) known as Cytokine storm. Thereby, affected individuals experience some adverse symptoms like toxic shock syndrome and rheumatic fever.
