Answer:
Given the nature of descriptive statistics, psychologists will use descriptive statistics to assemble data about their clients through their observations of clients' behavioral patterns. Then a sample of the data will be taken. The sample is summarized statistically, interpreted, and recorded. Psychological reports can be issued based on the observed statistical results.
Explanation:
Psychologists and other occupations use descriptive statistics to describe the basic features of the data in their studies or experiments. Descriptive statistics provide simple generalizable summaries about the observed sample and the calculated measures. Using simple graphics, they form the basis of quantitative data analysis.
Answer:
Explanation:
On someone with a normal genetic variation, the environment helps them adapt and pushes for the evolution of the traits that will help that species increase their chances of survival in future generations. This includes traits such as height, thus increasing this trait so that the species is able to reach food in higher places or reach higher places in order to find shelter. This does not have the same effect when dealing with a certain genetic mutation such as dwarfism since the mutation targets a specific value for these traits and is not affected by its environment.
The environment can influence height in individuals with normal genetic variation through factors such as nutrition and exercise. However, the impact of the environment on someone with a mutation leading to dwarfism is less significant.
The environment can impact a multifactorial trait like height in someone with normal genetic variation through factors such as nutrition, exercise, and overall health. For example, a well-nourished individual who engages in regular physical activity may reach their full potential height. On the other hand, an environment with inadequate nutrition or limited access to healthcare could lead to stunted growth and shorter height.
In the case of someone with a mutation resulting in dwarfism, the impact of the environment may be less significant. Dwarfism is primarily caused by genetic mutations that affect the production of growth hormone. While environmental factors can still influence overall health and well-being, they are unlikely to significantly alter the person's height.
Therefore, the environment plays a more prominent role in affecting height in individuals with normal genetic variation compared to those with a specific genetic mutation causing dwarfism.

(b) False
Answer:
Explanation:
The cell membrane separates the cell from the outer environment. The extracellular fluid contains the sodium ions (Na+), chloride ions (Cl-), while intracellular fluid contains potassium (K +) and negative anions.
The potential difference arises when the membrane is selectively permeable to some ions. The resting potential is -70mV.
When the neurons get excited, the sodium ions start to enter by sodium channels.
Now there are more positive ions inside the cell membrane. It disturbs the resting potential i.e. -70mV. This stage is known as depolarization.
When the inside environment of the cell is more positively charged, the potassium ions start to move out of the cell. It goes out by the voltage-gated channels. Thus resting stage is maintained and it is known as repolarization.
But the initial stability of the cell membrane has to be maintained. To restore the resting stage, the sodium ions start to move out of the membrane and potassium ions enter into the cells again. This is an active transport and has done by the Na+ - K+ pump. Here 3 sodium ions move out and 2 potassium ions pumped into the cell through the plasma membrane.
Thus the resting potential regains. The potassium ions come back into the cells against the concentration gradient and ATP provides the energy for this phenomena.
Answer:
False.
Explanation:
Neuron or nerve cell may be defined as the structural and functional unit of the nervous system. The neurons conduct the nerve impulse and helps in the transmission of signals.
The depolarization of the cell occurs due to the influx of sodium ions into the cell. For the cell membrane to be in resting potential, the potassium ions moves inside the cell from outside the environment and not out of the cell of the organism.
Thus, the correct answer is option (b).
