With the help of examples, explain the
secondary structure of proteins.

2. Two chambers A and B are separated by a
membrane which is permeable to Cl⁻ , but
not to K⁺. Chamber A is filled with 100 mM
KCI and chamber B with 10mM KCl. For
the above situation answer the following
questions :

(a) Do these chambers remain in state of
electrical neutrality before any
movement of the ions starts ? Give
reasons.

(b) Explain what happens when the
diffusion starts.

Fill in the blanks :

(i) __________do not have the well-
defined organelles.

(ii) In amylose, glucose molecules are
linked together by ___________
linkage.

(iii) The pieces of DNA synthesised
discontinuously away from the
replication fork are called ___________ .

(iv) In allosteric enzyme regulation, the
effector molecule binds non-covalently
to the ____________ site of the enzyme.

(v) Simple lipids are formed by the combination of three fatty acid molecules with a ________
molecule .

Give the appropriate terms used for each of the following :

(a) The process of twisting of non_sister
chromatids around each other during
meiosis.

(b) The cell organelle which is the site of
protein-synthesis.

(c) The protein coat surrounding the
genetic material of a virus.

(d) The movement of solute across the
membrane from higher concentration
to lower concentration mediated by a
transport molecule.

(e) The energy required to break the
energy-barrier in order to start a
reaction in a biological system.

Outline the micro and macro structures that are present in connective tissue (bone) and muscle (cardiac, skeletal and smooth)

(Anthropology) How can I Respond to this Person if I agree or Disagree with her and give and explanation.

I personally believe that the Gigantopithecus can possible exist in the form of Big Foot since of course over the years animals do evolve so it may actually be possible that the Gigantopithecus did evolve and got a little smaller than what they were before. Instead of standing at 9’8” they now probably only stand like 6’6”-7’0 and weight between 300-500lbs. When reading and looking at evidence of Big Foot, we see that Big Foot does look very similar to the Gigantopithecus, fully covered in hair, large feet, tall, and walks like a monkey. I think people are so fascinated by Big Foot because people have only caught glimpses of it and never actually came in direct contact with it. It makes people really wonder what is Big Foot, is he a monkey or a human, I think that’s what fascinates people the most, Big Foot is an unidentified creature.
