Answer: Option (1) and (3)

Explanation: Radiometric dating is a very efficient method of dating a rock or fossil or any object. It helps in determining the estimated age of that particular object.

The half-life of all the radioactive methods are already known, so it becomes easy to determine how much decay an object has undergone. So by knowing the rate at which the decay occurs, one can find out the approximate age by using the radioactive decay formula.

Thus, the correct answer is option (1) and (3).

Seasonal changes in carbon dioxide concentration with the highest levels measured in May and the lowest levels measured in October will affect the photosynthesis rate due it is a reactant which is required during photosynthesis.

<h3>What are the photosynthetic chemical reactants?</h3>

Photosynthetic chemical reactants are those materials required to carry out photosynthetic reactions which include carbon dioxide and water molecules. These materials are used to generate simple carbohydrates such as glucose and oxygen.

Photosynthesis also requires sunlight to excite the electrons of chlorophyll molecules in order to generate chemical energy (glucose)

Therefore, with this data, we can see that the photosynthetic chemical reactants include both carbon dioxide and water, thereby fluctuations in the levels of these materials will affect the photosynthesis rate and thus may lead to a decrease and or an increase in the amount of photosynthetic products (i.e. oxygen and also glucose).

kodGreya [7K]

Answer:

monoclonal antibodies

Explanation:

Monoclonal antibodies are antibodies that are made by identical immune cells which are all clones of a unique parent cell.

Monoclonal antibodies can be isolated such that they will be able to only recognize a unique epitope, this makes them to be suitable for determining the expression one or two identical sequenced proteins. Monoclonal antibodies technique is one of the most effective chromatography techniques.

Polyclonal antibodies contain different epitopes on a protein, hence suitable for protein identification but not suitable for determining the expression of one or two identically sequenced proteins.

What would most likely be a result of skepticism ​
disa [49]

Answer:

The two most frequently made objections to skepticism target these theses. The first is that the skeptic’s commitment to our epistemic limitations is inconsistent. He cannot consistently claim to know, for example, that knowledge is not possible; neither can he consistently claim that we should suspend judgment regarding all matters insofar as this claim is itself a judgment.
