Biology

Answer:

The specific distant organ which is affected by a specific hormone secreted by a  endocrine gland is called the target organ. For example, oxytocin secreted by the posterior pituitary affects the contraction of the walls of uterus resulting in parturition. Here, the uterine wall is the target organ.

Explanation:

  • Endocrine system is a system of ductless glads that secrete and pour chemical messengers into the blood and control various metabolic activities of the body.
  • Hormones are  signal molecule that are produced by endocrine gland and are directly poured into the blood.
  • According to current scientific definition : Hormones are  low molecular weight, chemically heterogeneous non-nutrient substances which produced in trace amounts and act as inter-cellular signal molecules.
  • Even though blood distributes hormones throughout the body, only specific target cell can  respond to each hormone because only the target cell have receptors for binding with particular hormone.

Why would prokaryotic cells be considered a simple cell when compared to eukaryotic cell?
Ede4ka [16]

Answer:

Prokaryotic cells are more simple and smaller than eukaryotic cells. Prokaryotic cells are structurally more simple because of their small size. It's also defined as the smaller a cell size, the greater is its surface to volume ratio (means surface area of a cell compared to its volume).

In smaller prokaryotic cells, a large surface to volume ratio is present. It means that nutrients can rapidly and easily reach any interior part of the cell.

The large eukaryotic cell have limited surface area as compared to its volume it means that nutrients cannot rapidly reach to all interior parts of the cell, because of that eukaryotic cells are more complex than prokaryotic cells, and they require specialized internal organelles to carry out processes like provide energy, metabolism and transport necessary chemicals throughout the cell.
