True.
Parenchyma cells are the most abundant type of cells in a plant since they make up parenchyma tissue which is the most common tissue in plants.
Parenchyma cells have thin walls, and posses large vacuoles as well as distinct intercellular spaces.
Parenchyma cells have many functions. Each function is largely determined by where the cell located.
Those found in roots and stems are used to store food in form of starch, and water. The large vacuoles in the cells is where the food and water are stored.

Because the population is in hardy-weinberg equilibrium, that means the sum of m and n alleles frequency would be 1
If m is 0.4, then n would be:
m+n=1
0.4+n=1
n=0.6
The frequency of organism with heterozygote genotype would be:
2 * m* n= 2 * 0.4 *0.6=0.48=48%</span>
Answer:
The endocrine system assists in maintaining and regulating different functions of the body by producing and discharging hormones. It comprises glands situated throughout the body, which produce chemicals known as hormones directly into the blood. The levels of hormones in the blood are monitored by a highly unique homeostatic mechanism known as feedback.
The two kinds of feedback are common, that is, negative and positive feedback, of this positive feedback, is the rare mechanism. It augments the changes done rather than opposing them. For example, the discharging of oxytocin from the posterior pituitary gland at the time of labor is an illustration of a positive feedback mechanism.
The stimulation of the muscle contractions, which pushes the baby via the birth canal is done by oxytocin. This discharging of oxytocin leads to an augmented or stronger contraction at the time of labor. This contraction is enhanced and intensify until the baby comes out of the birth canal. However, when the stimulus to the pressure receptor terminates, the generation of oxytocin ceases, which eventually results in the stopping of labor contractions.
Uterus<span>Once girls become sexually mature, the outer labia and the mons pubis are covered by pubic hair. A female's internal reproductive organs are the vagina, uterus,fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the <span>uterus</span></span>
