Answer:
The Y chromosome is an accurate indicator of a person's external sex organs.
Explanation:
Since females have two X chromosomes while males have one X and one Y chromosome, if you are aware of the presence of a Y chromosome you can safely assume that a person is a male. Therefore, you can assume what external sex organs a male has.
Answer:
The correct statement is - option B.
Explanation:
Unmyelinated axons are the axon that lacks the covering of scwann cells that form the myelin sheath which helps in the transfer or transmit the signals faster and more effectively in neurons. It acts as the insulating layer.
In absence of the myelin sheath, the action potential found everywhere along the length of the axon which leads to slow propagation than in myelinated axons.
Thus, the correct answer is - option B.
Answer:
A) Formulate question,conduct research,propose hypothesis,test hypothesis
Explanation:
The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:
1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.
2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.
3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.
4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.
