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>
Cause living things can not directly use most of matter which they found in nature. For example carbon, all organism use carbon in complex structure, that is in compound or macromolecule(glucose,fructose,amino acid). we can not directly earn ATP from C which we found in soil/other sources.
Answer:
The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.
Explanation:
To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.
A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.
The correct answer is answer choice A, 'In predation the predator usually kills its prey, whereas in parasitism the parasite does not usually kill its host'. While parasites can occasionally kill their hosts, it is more beneficial for the parasite to keep its host alive so that it can continue surviving off of the nutrients it gathers. Answer choice B is incorrect because the prey in predator-prey relationships and the host in parasitism do not benefit. Answer choice C is incorrect because the host does not benefit in parasitism, and is often harmed by the parasite. Answer choice D is incorrect because a predator usually kills its prey, while a parasite usually does not kill its host.
Hope this helps!
