There, each vas deferens joins with a seminal vesicle and forms the ejaculatory duct. For ejaculation, sperm passes through the ejaculatory ducts to mix with fluid from the seminal vesicles, prostate, and other glands to form semen. The semen travels through the urethra and comes out the end of your *****. Frequent ejaculation will not cause the body to run out. Although it takes the average sperm about 74 days to fully mature, the body makes millions of sperm each day. Men with healthy, normal sperm counts should not worry about the effects of regular ejaculation.

The lanthanide contraction is the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72, hafnium. The Lanthanide Contraction is caused by a poor shielding effect of the 4f electrons. Gd because as atomic number increases, the atomic radius decreases. Yb because it has a larger atomic number.

Binary fission: It involves the longitudinal or transverse splitting of an organism into two equal halves which develop into two separate individuals.
• Binary fission is generally seen in unicellular organisms such as amoeba and paramecium falling into the category of protozoa. Amoeba is a simple, unicellular organism which reproduces by binary fission. The division begins with the division of nucleus.
• Binary fission can also be observed in multicellular animals like sea anemones and planarians.
Budding: This is a form of asexual reproduction which involves development of small mass of cells as protuberances on the parental body to give rise to new structures called as buds. These buds separate out from the parental body and develop into new individuals. Two types of budding are external budding and internal budding.
Cloning: It involves the creation of an exact copy of a biological entity.
• Cloning involves the process of forming a cell or a complete individual from a body cell.
• A clone is created by inserting the complete genetic material of a regular body cell from a donor into a recipient.
• Cloning is done in many animals including sheep, cattle, pigs etc. But for the first time cloning of sheep was successful in producing a clone of the parent sheep.

Fertilization takes place in the fallopian tube. The copulation is timed such that the sperms reach the fallopian tube when ovum is still there and will then only be able to cause effective fertilization. Hence, all copulations do not result in pregnancy.

Let the length of each side of square = s
Now length of diagonal of square = 12 cm
{tex}\begin{array}{l}\Rightarrow\sqrt2\mathrm s=12\\\\\Rightarrow\mathrm s=\frac{12}{\sqrt2}=\frac{12}{\sqrt2}\times\frac{\sqrt2}{\sqrt2}=\frac{12\sqrt2}2=6\sqrt2\mathrm{cm}\\\\\mathrm{Now},\mathrm{area}\mathrm{of}\mathrm{square}=\mathrm s^2=\left(6\sqrt2\right)^2=6\sqrt2\times6\sqrt2=72\mathrm{cm}^2\end{array}{/tex}
