First, you need to know that 1 mm = 1000 μm. So when the red blood cell is drawn 100 times larger than its actual size, the drawn size is 8 * 100 = 800 μm = 0.8 mm. So the right answer is B.
Answer: Incomplete dominance
Explanation:
Incomplete dominance is said to have occurred when offsprings with heterozygous phenotype results from the interaction of two homozygous phenotypes.
For example: A red-colored plant crossed with white-colored plant to give pink-colored offspring shows incomplete dominance.
Also, some flowering plants like Mirabilis Jalapa, Four 'o' clock plants, give offsprings with traits that are intermediate between those of the parents.
Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
Answer:
True
Explanation:
Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.
