Gigantism
and acromegaly are the two diseases resulting from hyper function of the
pituitary gland.
Gigantism
and acromegaly are conditions that are nearly always due to a pituitary adenoma
that is because of excessive secretion of a growth hormone called hypersomatotropism.
<span>If GH
hypersecretion begins in childhood, before closure of the epiphyses pituitary
gigantism occurs. It is a rare condition where skeletal growth velocity and
ultimate stature are increased, but little bony deformity occurs. However,
soft-tissue swelling occurs, and the peripheral nerves are enlarged. Hypogonadotropic
hypogonadism and deferred puberty is also normally present, resulting in a
eunuchoid habitus. While Acromegaly
occurs after the growth plate cartilage fuses in adulthood, it is the same
disorder of IGF-I excess but in acromegaly, an unadorned disease that morbidity
and mortality rates are high because its often diagnosed late, where the
disease is associated with cardiovascular, cerebrovascular, and respiratory
disorders and malignancies. </span>

Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
Explanation:
Answer:
presence or absence of a protective covering over the ovule
Explanation:
In angiosperms, seeds develop from ovules and are enclosed in the ovary. So, their is the presence of protective covering making the seeds enclosed.
On the other hand, gymnosperms have seeds that are borne on cones, so they are naked due to the absence of any protective covering over the ovule.
