Resource partitioning
Resource partitioning refers to differences in resource use
between species regardless of the origin of the differences. Similar species
can coexist in the same ecological community without one pushing the others to
extinction through competition. Species compete for the same resources which
include nutrients and habitats which are the raw materials needed by organisms
to grow, live, and reproduce. For the question given above, the divergence in
lizards is an example of resource partitioning.
Steroid hormones easily diffuse through the cell membrane. The hormone binds to its receptor in the cytosol, forming a receptor–hormone complex. The receptor–hormone complex then enters the nucleus and binds to the target gene on the DNA.
Answer:
Graves´ disease is an autoinmmune disease that is caused when the immune system attacks the cells of the thyroid gland, which leads to an overproduction of the hormones secreted by the thyroid gland. This constant attack and destruction on the part of the immune cells causes the thyroid to increase in size, a condition that is commonly known as hyperthyroidism.
Hyperthyroidism can become a really serious issue because the excessive production of the hormones of the thyroid gland will increase the metabolic activity of all parts of the body and can, if left untreated, cause such serious conditions as blood clotting problems, type 1 diabetes, among others.
Answer:
Mitochondria: It is also called power house of the cell because it genetates or produces energy for the cell which is required for different functions. The glucose which is absorbed by the body is taken to the cell and from there the glucose is entered in the mitochondria. The mitochondria start break down of the glucose molecule and generates energy in the form of Adenine tri phosphate (ATP).
