Biology

Answer:

Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.

Explain Gynecomastia in males.
PolarNik [594]

Gynecomastia is an increase in the size of the mammary gland in men. The condition can occur in one or both breasts. It starts as a small mass under the nipple, which can be sensitive. One breast can be bigger than the other. Its cause is an imbalance between the stimulatory effects of estrogen (female sex hormones) and the inhibitory effects of androgens (male sex hormones) in the breast tissue, when the first ones increase, or the second ones descend.

Gynecomastia is a problem relatively common in the population, and there are three prevalence peaks throughout life:

Newborns: Between 60 and 90% of newborns have gynecomastia, produced by the passage of maternal estrogens through the placenta. It is a transient gynecomastia that disappears in about 2-3 weeks.

Puberty: Gynecomastia in puberty affects mainly young people aged between 10 and 14 years, and is due to the transient and physiological increase in estrogen that occurs at this age.

Elderly: Is due to an increase in fatty tissue with a greater peripheral aromatization ( a process that occurs in adipose tissue and that involves the conversion of androgens into estrogens), a decrease in the production of testosterone by the testes and the use of drugs.

The body cavity is reduced in leeches, and the bristles are devoid of some specialized morphology, including leeches. An important phylum of invertebrates in the animal kingdom, Annelida, consists of more than 9,000 species divided into three classes: Sea worms (polychaetes) are divided into motile and sedentary or tube-dwelling forms. earthworms (Oligochaeta); and leeches (Hildinea). Annelids are coelomic and tridermal.

General characteristics of annelids are:

  1. They show organization at the organ system level.
  2. Your body is segmented.
  3. They breathe through their body surfaces.
  4. The kidney is an excretory organ. They have well-developed circulatory and digestive systems.
