The chemiosmotic model requires an intact outer mitochondrial membrane. is supported by the observation that, when isolated mito

chondria have an artificial electrochemical gradient (higher pH in the matrix) imposed on them, electrons spontaneously flow through the respiratory chain. is supported by the observation that isolated mitochondria that are actively respiring cause the pH of the solution they are in to increase. requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.

Answer:

requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.

Explanation:

The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.

lora16 [44]

Answer:

Option B, Traits are inherited in discrete units and are not the results of "blending.

Explanation:

Hutchinson-Gilford progeria syndrome cause early aging in children and is genetic in nature.  It is very rare in nature and  causes hardening of arteries which may lead to heart attack or stroke at a young age.  

It is caused by the mutation in the LMNA gene that codes for lmin A which is responsible for shaping the nucleus of the cell. It is an autosomal dominant disease and even a single gene copy can cause this disorder. Every time this disorder is reported, no genetic link or history has been observed till date and it is believed that it occur in an individual with no genetic history for Hutchinson-Gilford progeria syndrome. This leads to a conclusion that every time new mutation occurs in the LMNA gene and hence it remains unblended.  

Hence, option B is correct

allsm [11]

Answer:

Extract of beet roots has the capacity to melt ice

Explanation:

<em>A prediction in research is a tentative statement that can be proven or disproven using an experiment. Predictions are otherwise referred to as hypotheses.</em>

In the illustration, the prediction would be that the extract of beet roots has the ability to melt ice. After the experiment, the prediction would either be proven right or otherwise.
