Answer AND Explanation:

MALES

Testes: they are oval shaped structures that produce the male gametes and sex hormone called testosterone.

Seminiferous tubules: tubules where spermatogenesis occurs.

Vas deferens: are tubules which lead to the epididymis.

Epididymis: is along, coiled tube for storage of sperms. it contraction and relaxation pushes sperms out and allows ejaculation through the urethra.

Accessory glands like the seminal vesicles, cowper's gland and prostate gland produce seminal fluid that provides a nutrient medium for sperms to swim in.

Scrotum: contains the testes outside the body.

FEMALES

Ovary: these are oval-shaped structures that produce female gametes and sex hormones.

Oviduct: these are hollow structures with an expanded funnel-shaped opening which accepts the released ovum and directs it to the fallopian tube. Fertilization takes place in the oviduct  forming zygote.

Uterus: has an inner layer called endometrium which becomes folded and  vascularised to allow implantation. The endometrium nourishes the embryo..

Cervix: is a muscular ring between the uterus and the vagina. It secretes a plug of mucus, which prevents entry of pathogens and air

The vagina is a muscular copulatory canal into which penis enters. Vagina also allows passage of foetus during parturition.

Answer:

BENEFITS:

The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.

A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.

The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.

LIMITATIONS:

<u>descriptive  method  of  investigation </u>

It cannot be used to correct variable or be used to determine causes and  effect  of  the  problem

<u>experimental  method  of  investigation </u>

It might create an artificial situation that do not always represent the real  life situation

<u>comparative  method  of  investigation </u>

It  is not easy to control other variables that might influence the study

Did earth experience normal or reverse polarity 1.5 million years ago
azamat

Normal polarity

Explanation:

Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.
