The answer is speciation by geographic isolation. When the population of a species gets separated due to reasons such as continental drift, mountains, canyons, etc. then each separated group of population may survive and adapt to their respective environment leading to speciation. These barriers do not allow the evolving populations to interbreed initially and over time when they evolve into different species they become completely reproductively isolated.
I got to tell u but it’s b
C or E, the Iliac arteries are split from the descending aortic artery. They split in the pelvic following the left and right lower limbs. They then turn into the femoral arteries the run on the inside of your thigh along the inner part of your femur. However, the location that they split may be just right to also supply oxygenated blood to the reproductive organs.
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
On my work the answer was D ..
