Answer:
Star-shaped.
Explanation:
Neurons are the nerve cell that acts as the basic structural unit of the nervous system. Neurons helps in the transmission of nerve impulse and transmit the signal into different parts of the body.
There are basically four types of microscopic neuron : unipolar, bipolar, multipolar and pseuounipolar neuron. Star-shaped neurons are not found in the microscopic description of neuron.
Thus, the correct answer is option (a).

Answer:
The correct answer will be option-The mice will die. Transformation of genetic material from R to S was required.
Explanation:
Frederick Griffith performed an experiment on the mouse using two strains of the <em>Streptococcus pneumonia</em> which are R (rough avirulent strain) and S (smooth-virulent strain).
In the experiment when he injected the live S bacteria with dead R bacteria, the mice died, opposite of the expected result that mice would not die. This amazed Griffith and he concluded that some transformation of the bacteria has happened due to which the mice died. The R bacteria became S bacteria (virulent) due to the transformation which was proved later that the bacteria took the DNA of the dead S bacteria from the surrounding.
Thus, the selected option is the correct answer.
Answer:
The growth rate is 1250 per year.
Explanation:
- First of all, lets consider the population number in both years;
The initial population is 1200, and
Final population is 3700.
- Total increased population is (3700- 1200) = 2500
So 2500 population were increased in (2006 - 2004)= 2 years.
- To find the annual growth rate: (Increased population/ time span in years)= 2500/2= 1250 per year.
- Hence 1250 population was added per year in walleye from 2004 to 2006.
Unicellular organisms have only one cell in which a<span>ll seven life processes take place.</span><span>
These unicellular organisms are self-sufficient. They do not need outside help to function. The multi-cellular organism has to rely on other cells to survive. So, the difference between the cells is that the cells from a multi-cellular organism are interconnected to each other and work together.</span>
