Which of the following statements describes a covalent bond between Carbon and Hydrogen:

#I Life Science/ Life Sciences Group – I-V
  1. The electrons are shared equally between the two atoms of the bond.

  2. The electrons of the bond are pulled closer to the nucleus of Hydrogen, because its outer shell electron is closer to its nucleus than the outer shell electrons of Carbon are to its nucleus.

  3. The electrons of the bond are pulled closer to the nucleus of Hydrogen, because its nucleus contains more protons than Carbon.

  4. The electrons of the bond are pulled slightly closer to the nucleus of Carbon, because although its outer shell electrons are located farther away from the protons of its nucleus, it contains more protons than Hydrogen.

The insect ingests plant tissue containing the fatty acids, an enzyme in the gut conjugates the plant-derived fatty acid to an insect-derived amino acid to form an elicitor, When plants recognize elicitors from insect saliva induces some typical responses such as

a) Increasing Ca2+ levels in the cytosol and then activate an array of target proteins, such as calmodulin and other Ca2+-dependent protein kinases

b) In Arabidopsis, a calmodulin-binding transcriptional regulator called IQD1 was identified as an important mediator of defense responses against insect herbivory

c) overexpression of IQD1 in Arabidopsis activate the herbivore activity

d) IQD1 binds calmodulin, a major Ca2+-binding protein, in a Ca2+-dependent manner and subsequently inhibits the gene involved in glucosinolate biosynthesis

Which of the following combination from above statements is correct?

Hormonal interactions contribute to plant–insect herbivore interactions such as— ethylene, salicylic acid, and jasmonic acid. In particular, ethylene appears to play an important role in this context, what will be the effect of ethylene when is applied alone and when is applied with other amino acids?

a) ethylene applied together with JA it seems to reduces defense responses

b) Ethylene appears to applied alone to plants, ethylene has little effect on defense-related gene activation

c) when ethylene applied together with JA it seems to enhance JA responses or defense responses are significantly increased

d) Ethylene appears to applied alone to plants, ethylene has more effect on defense-related gene activation

Which of the following combination is correct about ethylene effects?
