Answer:

cAMP dependent pathway is important for processing of life.

Explanation:

cAMP pathway is also called as adenynyl cyclase pathway.

This mechanism requires different steps like-

  1. G protein coupled receptor is a integral protein that is activated by different external stimuli which binds with the specific ligand.
  2. Extracellular ligand causes activation of GPCR which in turn is responsible for conformational change  in the receptor and allows it to bind with the intracellular heterotrimeric G protein complex.
  3. The Gα  stimulate G protein complex to exchange GDP for GTP and then the complex is released.
  4. Activated Gα binds with adenylate cyclase and catalyzes ATP to form cyclic AMP.
  5. Activation of cAMP leads to the activation of nucleotide gated ion channel, and PKa(Protein kinase A) which is also called as cAMP dependent enzyme.
  6. Once, PKA is activated,it causes phospholylation of other proteins like AMPA receptor,transcription factors which regulate gene expression, and convert glycogen into glucose.

What is the significance of the evolution of Hox gene clusters during vertebrate evolution?
AlexFokin [52]

Answer:

Duplication of Hox genes made increased morphological complexity possible.

Explanation:

  • The hox gene cluster consists of a group of related genes that function to controls the basic body plan of an embryo and also define the head to the tail axis.
  • These are mainly responsible for ensuring the correct position of al the structures in the body.
  • Since the anterior-posterior axis all the vertebrates are established by these hox genes this points out to the fact that common information is needed amongst all he vertebrates to define the various morphological variations that occurred.
  • The hox genes have shown duplication in the course of evolution and they have undergone a four-fold duplication which has led to the generation fo different structures in the various organism and is thus responsible for the increased morphological complexity.

HELP FAST PLEASE??!!!! An isotope of Chlorine has a half life of 55.5 minutes. If we start with 45 kilograms of this isotope, Ho
grandymaker [24]

 The  amount   that will remain after 3.7  hours  for isotope  chlorine that has a half  life   of 55.5  minutes  is 2.813  kg


 Explanation

Half  life  is the  time required for the  radio activity  of  a specified isotope  to  fall  to  a  half its  original value.

convert 3.7  hrs  into  minutes

= 3.7  x 60 = 222 minute

 find the number of half life  that chlorine  isotope undergo   in  222  minutes

=222  minutes /  55.5   minutes = 4  half life


therefore   45 kg after first half life  =45 kg /2=22 .5 kg

                  22.5  kg after second  half life =  22.5/2 =11.25  kg

                 11.25  kg after third half life  = 11.25/2 = 5.625 kg

                5.625  kg  after  fourth  half life =  5.625/2 = 2.813 kg
