Uigi Aloisio Galvani (Latin: Aloysius Galvanus; 9 September 1737 – 4 December 1798) was an Italian physician, physicist, biologist, and philosopher, who discovered animal electricity. He is recognized as the pioneer of bioelectromagnetics. In 1780, he discovered that the muscles of dead frogs' legs twitched when struck by an electrical spark.[1]:67–71 This was one of the first forays into the study of bioelectricity, a field that still studies the electrical patterns and signals from tissues such as the nerves and muscles.

What are some advantages and disadvantages of long femur lengths (crickets)?​
MrRa [10]

Answer and Explanation:

In crickets, femur length represents a highly important trait associated with jumping performance - an essential behavior for their survival and reproduction.

According to research, these are the possible advantages and disadvantages in regard to long femur length:

Advantages

  • Longer legs [may] provide higher power for the muscles in order to jump.
  • Long-legged crickets generate lower reaction forces while performing a jump, which enables them to lose less energy in comparison with crickets with shorter femur length.

Disadvantages

  • Longer femurs may increase the total take-off time of a cricken prior to a jump.
  • In some cases, longer femurs force insects to develop head or body structures to enable them to 'fit' the legs while they prepare to jump.
  • Increased energy loss while jumping from an elevated leaf.

Grams staining i a staining method used to classify bacteria into two main classes. Gram positive and Gram negative.

They are differentiated according to the ability of their cell wall to retain the primary stain color of the crystal violet stain or the counter stain pink.

Bacillus subtilis is a Gram positive bacteria hence it is supposed to stain purple.

Therefore, when it stained pink is an error. it shows loss of the cell wall integrity due to old age, overdecolorization or over fixing with heat.
