"All of the following describe real experimental results. One does NOT support the predictions of Hamilton's rule. Which one?

Biology

Answer:

Option-C

Explanation:

Hamilton gave the mathematical expression for the altruistic behaviour or trait in a population which suggested that the alleles for altruistic behaviour will be favoured by the natural selection if BR-C > 0.

The mathematical expression for the altruistic trait is rb> c

where r - relatedness, b- the benefit to recipient and itself also and c-cost to an actor.

In the given question, all the cases meet the condition of Hamilton's rule except one which is the In- law bee-eaters which raise the young near to the nest as the parents who can raise the young ones are not benefited personally from the action of the young as the young one treat them as non-kin. This does not fulfill the condition of the Hamiltons rule.

Thus, Option-C is correct.

Consider aerobic cellular metabolism from the beginning to end. What is the sequential order of the metabolic processes that sta
poizon [28]

Explanation:

This starts with substrate level phosphorylation(glycolysis) in the  cytosol of cytoplasms.Two ATPs are needed for phosphorylation of glucose.With eventual formation of  4 ATPs with 2NET GAIN ATPs,NADH+,and Pyruvate.

The Pyruvate reacts with co-enzyme A to form Acetyl coA-This is the bridge reaction or link reaction.

The Acetyl Co-A diffuses into the mitochondria where it combines with oxaloacetate to form citrate,the latter form Alpha ketoglutaric succinic,fumate,malate and back to oxaloacetate.The cycle of events is called the Kreb's Cycle.

Net of 2ATPs are formed,co-enzymes NADH+ and FADH2 ,water molecules,and Co2  are produced.These takes place in the mitochondria.

Then the NADH+ and FADH2 takes the hydrogen ions into the inner mitochondria where Hydrogen is split into electron and Protons.This forms the beginning of oxidative phosphorylation.

The electrons are transmitted by the carrier proteins to form the electron transport chains,which provide the PMF. The latter pumps the protons across  the walls of mitochondria into the intramembrane space.

The high concentration of the protons produce the elecrochemical gradients which make the protons to diffuse back into the matrix. it is the changes in the elctrochemical gradients that supply the energy  needed by ATPase enzymes for synthesis of ATPs. A total of 28ATPs are produced in oxidative phosphorylation.

Answer:

The total ATPs produced in the sequence of glycolysis pyruvatre,Co-enzyme A, kreb's Cycle and oxidative phosphorylation are  32ATPs per molecule of glucose splits in Glycolysis.
