Out of the options I would have to say Penetrating Keratoplasty, I am not sure
Answer:
Hilda and her family are going on a sailing trip this summer, and Hilda is especially interested in spotting dolphins. In which zone of the ocean is Hilda most likely to spot dolphins? Hilda and her family are most likely to spot dolphins in the PELAGIC zone. To view shorebirds and crabs, Hilda should move towards the INTERTIDAL zone.
Explanation:
The Pelagic Zone
It is any water in an ocean or lake that can not be said to be positioned in proximity to the shore or in proximity to the bottom (the shore and the bottom are two distinct zones with a completely different properties.
Divisions of the Pelagic Zone
It can be grouped into subzones based on depth, we have the epipelagic, close to the top of the zone which as light been present, and the abyssopelagic, is nearer to the bottom with light being absent.
The intertidal zone
Its found between the high tide (upper limit) and low tide lines (lower limit), majorly on the beach at the water's edge.
The major attribute of the intertidal zone is that it is immersed with water at high tide and is in exposure to the air at lower limit. The intertidal zone is usually undergoing alterations leading to organisms that are uniquely adapted to strive there.
Organisms found in this zone are sea stars, crabs, mussels, barnacles, and various corals as they well situated to strive immersed in water and a region of their lives open air at lower limit.
The statement, which best describes the evidence that Group 3’s data are less valid than the data for the other two groups is this: GROUP 3’S pH VALUE FOR VINEGAR IS MUCH HIGHER THAN THE VALUES OF THE OTHER TWO GROUPS.
An experimental result is said to be valid, if it gives the true values of the parameters it has measure. Looking at the experimental results given in the question above, one will notice that, the pH value obtained by group 3 for vinegar is quite different from that of the other two groups. In addition, the value is wrong, this is because, vinegar is acidic in nature. The result obtained by group 3 indicates that vinegar is basic, which is wrong. This shows that the results obtained by group 3 is less valid than that of the other two groups.
Answer:
The correct answer is - option C.
Explanation:
Proteins are made up of long chains of polypeptide chains made up of amino acids contain the basic elements of organic matter carbon, oxygen, and hydrogen with the addition of nitrogen.
In the given option set 1, and set 2 lacks the nitrogen elements whereas in set 4 the oxygen is not available, and set 3 have all the elements required for the protein.
Thus, the correct answer is - option C.
