Answer:
The population size grow /can grow
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
The functions of the organs during fertilization is illustrated below.
<h3>How to illustrate the function?</h3>
<u>Testes</u>: The testes are responsible for the production of the testosterone in males.
<u>Ovaries</u>: Ovaries are responsible for producing eggs for fertilization and they also produce hormones such as estrogen and progesterone.
<u>Vas deferens</u>: It helps in the transportation of mature sperm to the urethra in preparation for ejaculation.
<u>Semen</u>: It contains sperm cells that helps in the fertilization of female eggs.
<u>Uterus</u>: It helps in the nourishing and housing the fertilized eggs until the offspring is ready to be delivered.
<u>Seminal vesicle</u>: The function is to produce and store fluid which will eventually become the semen.
<u>Epididymis</u>: It carries and store the sperm cells that are created in the testes.
<u>Fallopian tube:</u> The function is to transport the ova from the ovary to the uterus every month.

Hardness is a measure of a mineral's resistant to abrasion. This property is easily determined and is used widely for field identification of minerals. More than a century ago. Friedrich Mohs (1773-1839), a German mineralogist, assigned arbitrary relative numbers to ten common minerals in order of their hardness.
Hardness
Mineral
Test
1 Talc Fingernail (2.5)
2 Gypsum
3 Calcite Cooper coin (3)
4 Flourite Knife blade (5.5)
5 Apatite
Glass plate (5.5+)
6 K-feldspar
7 Quartz Streak plate (7)
8 Topaz
9 Corundum
10 Diamond
A simpler version of the Mho's scale can be established using three types of hardness:
SOFT - Minerals that can be scratched with a fingernail
INTERMEDIATE - Minerals that cannot be scratched with a fingernail but can be scratched with a steel nail.
HARD - Minerals that cannot be scratched with a steel nail.
