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.
Phototropism as photo means light
eg: photosynthesis
Answer:
Change their external environment is the correct answer.
The tundra has little variation in temperatures
Answer:
a. different alleles of the seed shape gene.
Explanation:
Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.
