B if it’s not correct sorry
Answer:
C-14 from fossil had reached itshalf life
Explanation:
For radiactive isotopes (such as Carbon-14), per definition; the semi life or semi disintegration period; is defined as the time for which a certain mass isotope mass disintegrates to half of the atoms that make it up
For Carbon-14, this semi life period is 5730 years , and for the above example, as it is mentioned that we originally had 254 grams of C-14 but we currently have 127 grams (this is, exaclt half of the original mass of 254 grams), this leads us that 5730 years have passed since the original mass and the final mass (that is, one semi life period of C-14)
Answer:
A statement can contain one argument, more than one argument or no argument.
Argument are intended to determine the degree of truth hence enabling a conclusion to be made. It contains one or more premises and only one conclusion.
A premise is the statement in the argument that provides reasons to support a conclusion.
In the first statement, there is no argument. This is because there is neither a premise nor a conclusion
The second statement has a conclusion(the last sentence) and two premises(first two sentences) therefore it is an argument.
The confusion about 'fruit' and 'vegetable' arises because of the differences in usage between scientists and cooks. Scientifically speaking, a tomato is definitely a fruit. True fruits are developed from the ovary in the base of the flower, and contain the seeds of the plant (though cultivated forms may be seedless). Blueberries, raspberries, and oranges are true fruits, and so are many kinds of nut. Some plants have a soft part which supports the seeds and is also called a 'fruit', though it is not developed from the ovary: the strawberry is an example.
As far as cooking is concerned, some things which are strictly fruits, such as tomatoes orbean pods, may be called 'vegetables' because they are used in savoury rather than sweet cooking. The term 'vegetable' is more generally used of other edible parts of plants, such as cabbage leaves, celery stalks, and potato tubers, which are not strictly the fruit of the plant from which they come. Occasionally the term 'fruit' may be used to refer to a part of a plant which is not a fruit, but which is used in sweet cooking: rhubarb, for example.
So, the answer to the question is that a tomato is technically the fruit of the tomato plant, but it's used as a vegetable in cooking.
Hope this helps :)
