<span>The correct answer would be amoeba. So the amoeba consists of protoplasm and a nucleus. For an amoeba the nucleus is a major organelle, which is located centrally. As such a major organelle it naturally has a huge role, and that is that it controls reproduction (it contains the chromosomes) and many other important functions (including eating and growth).</span>
Answer:
A plant with large number of leaves could be danger of losing too much water.
Explanation:
Transpiration is a process that occur in plants which deals with the removal of water from the stomata present in the upper surface of leaves.
The rate of transpiration is directly proportion to the number of leaves present in a plant.
The presence of large number of leaves in a plant increases the transpiration rate of the later that is associated will losing too much water from the plant body.
I believe it is just 2 1/2 m.
Answer:
Female mammals undergo X-chromosome inactivation during early embryogenesis, thereby females are mosaic for the expression of X-linked genes
Explanation:
In mammals, males receive only one copy of the X chromosome and one Y chromosome, while females receive two copies of the X chromosome. The X chromosome contains approximately 1,000 key genes involved in development. In human female embryos, one of these two copies of the X chromosome is inactivated to prevent the imbalance caused by a double dose of X-linked genes, a phenomenon known as X-chromosome inactivation. The inactivation of one X-chromosome is a random process, thereby female cells are mosaics for all heterozygous X-linked alleles, where some embryonic cells have an inactive maternal X chromosome, while other cells have an inactive paternal X chromosome.
