Answer:
The test statistic for this hypothesis test is - 3.68.
Explanation:
A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.
Sample proportion = 38/50
= 0.76
Hence,
Test statistic
= 3.68
The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.
Answer: YES, SUPPORTED
Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.
These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.
In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).
Answer:
The options are
Complex
Identical
Inconsistent
Non-testable
The Answer is Identical
Explanation:
The groups of scientists in different parts of the world who are dating fossils found in a rock layer of the same geologic time period. The findings have to have some common characteristics which links it to being in the same geologic time period.
This however validates the fossils having to be identical to match those found in other parts of the world.
These changes are likely genetic mutations
<h2>Further Explanation
</h2>
Evolution is the process of change in all life forms from one generation to the next, and evolutionary biology studies how this evolution takes place. Every generation of organisms inherits traits owned by their parents through genes. <u><em>Changes (called mutations)</em></u> in this gene will produce new traits in the offspring of an organism. In an organism's population, some traits will become more common, while others will disappear. traits that help the survival and reproduction of organisms will be more likely to accumulate in a population than unfavorable traits. This process is called natural selection. The income of more offspring than the number of parents along with the inheritance of these traits is an additional fact about life that supports the scientific basis of natural selection. In a long time, this isolated population will become a new species.
