They would be closer together.
They would be shaped like a hill.
They would be shaped like a valley.
Answer:
The correct answer is - option C.
Explanation:
A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.
In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.
Thus, the correct answer is - option C.

Explanation:
The modern education system of the world has categorized the education according to the age group of the children which could vary depending on the country. The education given to the age of 2 to 12 years is usually considered elementary education as it provides the basic formal education to the students.
The children get their elementary education from the kindergarten to the eighth grade and thus, elementary is the correct answer.
_____Prostate gland adds a fluid that protects the sperm.
_____Cell membrane changes electrical characteristics, causing cortical reaction.
_____Sperm migrate through cervix and into uterus.
_____Bulbourethral glands add a fluid that protect sperm from acidic conditions in the urethra.
_____Male and female chromosomes congregate, restoring the diploid (2n) number.
_____Seminal vesicles add a fluid that provides a source of energy for active sperm.
_____Acrosome releases enzymes that break down outer layer of egg’s membrane.
_____Muscles at the base of the bladder contract, forcing semen through the urethra.
_____Sperm is produced in the testes and stored in the epididymis.
_____Sperm encounter oocyte in oviduct (fallopian tube).
_____Sperm travel through the vas deferens to the seminal vesicles.
Answer:
The correct sequence would be:
__1__Sperm is produced in the testes and stored in the epididymis.
__2__Sperm travel through the vas deferens to the seminal vesicles.
__3_Seminal vesicles add a fluid that provides a source of energy for active sperm.
__4__Bulbourethral glands add a fluid that protect sperm from acidic conditions in the urethra.
__5__Prostate gland adds a fluid that protects the sperm.
__6__Muscles at the base of the bladder contract, forcing semen through the urethra.
__7__Semen is ejaculated into the vagina.
__8__Sperm migrate through cervix and into uterus.
__9__Sperm encounter oocyte in oviduct (fallopian tube).
__10_Acrosome releases enzymes that break down outer layer of egg’s membrane.
__11_Cell membrane changes electrical characteristics, causing cortical reaction.
__12_Male and female chromosomes congregate, restoring the diploid (2n) number.
Fertilization is the process by which gametes of the male and female fuse with each other to form a zygote. In humans, it takes place inside the female body.
The events can be categorized as:
Pre-fertilization events: Sperm (or semen) in male and egg in the female is produced in testes (in males) and ovary (if females) respectively. Accessory glands such as seminal vesicle, bulbourethral, and prostate glands help in the formation of sperm in males.
Coitus: During this semen from a male is ejaculated into the vagina of a female with the help of erectile penis.
The semen then passes through the cervix to reach the uterus.
Fertilization: Four events take place to cause successful fertilization; sperm preparation (capacitation followed by acrosomal reaction), binding, a fusion of plasma membranes of sperm and egg, cortical reaction and activation of the egg.
Post-fertilization events: The zygote undergoes cleavage process to mature into an embryo.
