Answer:
Options (3)=> the Curiosity rover detected carbon in organic molecules.
Explanation:
The statement (1) and statement (3) are the most likely correct answers but since the question is likely to choose between one of the options(that is the options of 1 - 4), hence, there should be another options that will include options (1) and (3) in the question for us to be able to pick both options. But, since we are to pick one OPTION (3) WILL BE THE MOST CORRECT ANSWER.
So, you have been seeing " curiosity" all over in the question so what exactly is "curiosity''. Curiosity is a rover that is been use by the National Aeronautics and Space Administration(NASA) to enter the planet Mars since the year 2012.
THE REASON, OPTION (1) SHOULD NOT BE CONSIDERED IS THAT; Sulphur was said to be found in the John Klein rock and not its COMPOUND but sulphur itself.
Reabsorption of water and specific solutes occurs to varying degrees over the entire length of the renal tubule. Bulk reabsorption, which is not under hormonal control, occurs largely in the proximal tubule. Over 70% the filtrate is reabsorbed here.
Mitosis is the type of cell division the question is asking for
Answer:
A. His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.
Explanation:
Pyruvate is from the breakdown of carbohydrates such as glucose through glycolysis. Glucose enters the cytosol through specific transporters (the GLUT family) and is processed by one of several pathways depending on cellular requirements. Glycolysis occurs in the cytosol and produces a limited amount of ATP, but the end product is two 3-carbon molecules of pyruvate, which maybe diverted again into many pathways depending on the requirements of the cell. In aerobic conditions, pyruvate is primarily transported into the mitochondrial matrix and converted to acetyl-coenzyme A (acetyl-CoA) and carbon dioxide by the pyruvate dehydrogenase complex (PDC).
Initially it was proposed that pyruvate was able to cross the membrane in its undissociated (acid) form but evaluation of its biochemical properties show that it is largely in its ionic form within the cell and should therefore require a transporter.
Transport of pyruvate across the outer mitochondrial membrane appears to be easily accomplished via large non-selective channels such as voltage-dependent anion channels/porin, which enable passive diffusion. Indeed, deficiencies in these channels have been suggested to block pyruvate metabolism
Answer:
Allopatric speciation
Explanation:
Allopatric speciation, the most common form of speciation, occurs when populations of a species become geographically isolated.
