With sexual reproduction a sperm coming from the male must unite with the female egg. Both are needed for this kind of reproduction, and an offspring CAN'T be formed without both. Unlike asexual reproduction, the offspring of a mammal reproducing sexually is DIFFERENT from both parents, since the offspring is a combination of both the mother and the father.
An easy to remember example I use when thinking about what sexual reproduction is:
the formation of a human child. A mother with her egg and the father with the sperm is BOTH needed. If you think about siblings that come from the same parents (and therefore same gene pool) they are not all exactly identical to each other. Although they may have similar features, they look different and are NOT genetically identical
Therefor for your question the answer is D.
Hope this helped!
Explanation: Saturated fatty acids have single carbon-to-carbon bonds. Therefore, saturated fatty acids have straight structures while unsaturated fatty acids have bent structures. Saturated fatty acids are solid at room temperature and unsaturated fatty acids are liquid at room temperature.
Answer:
d. transilluminate the mass
Explanation:
Sometimes, painless hard or tender mass develop in the scrotum of men and can cause testicular tumors.
After detecting a scrotal mass, to reduce the size of the mass, the next assessment required is to transilluminate the mass in which testicles will be appear opaque on transillumination. Transillumination of mass will help to detect the orientation of mass which can be treated further.
Hence, the correct answer is d. transilluminate the mass
In late Paleozoic and much of the Mesozoic era the region was affected by a series of orogenies (mountain-building events) that deformed western North America and caused a great deal of uplift. Eruptions from volcanic mountain ranges to the west buried vast regions beneath ashy debris.
I would guess ocean currents
