An increase in sudoriferous gland activity is called hyperthyroidism.
It happens when these sudoriferous glands, which are also known as sweat glands, affect the thyroid gland in such a way that it starts producing excessive amounts of thyroid hormone, which leads to this condition. In normal amounts, thyroid hormone regulates metabolism, but if there is too much of it, it can cause problems.
On the islands of the Galapagos lives a group of birds called finches. There are 13 species in this group. These species have diverse ecologies--some eat seeds, some eat insects, some eat fruit, and some even eat cactus. Although the bodies of these species look fairly similar, their beaks are very different. That is because it is their beak that is adapted to these diverse ways of feeding (Figure 8.14).
Function of
centrioles
An organelle that forms a
spindle-shaped structure of protein fibers on which the chromosomes move during
nuclear division are called the centrioles. Centrioles are part of the animal
cell organelles. Hence, they are a small part of the microtubules organized and
set in a particular course. Microtubules include 9 sets. Centrioles contain a
cylindrical structure, packed with protein which is described as tubulin. Found
mostly in eukaryotic cells beside the nucleus.
A person with this genetic disorder has an extra x-chromosome. Their genotype is XXY.
