Answer:
Endocrine glands and their hormones
The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as in digestion.
Explanation:
comment how it helps
Answer: The answer is mutation and natural selection
Explanation:
When members of a population interbreed (marry one another), genes are recombined and spread in the entire population resulting in gene flow. However, the Dunkers family decision not to intermarry would prevent gene flow, rather favor the NATURAL SELECTION of some genes, making the DUNKERS family genetically unique from the remaining population
Answer:
The correct answer is - interdependence.
Explanation:
In this ecosystem, all the organisms, tree mice, and birds all depend on one another for their food and growth. Birds get their food from fruits from the tree and the fruits that dropped by the birds to the ground used by the mice for their food.
In return mice and birds spread the seeds of the tree to the area which helps in the growth of the more trees. This relationship among the organisms is an example of interdependency.
Answer:
Célula procariota y procariotas.
Explicación:
La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.
Answer:
recognizes a hormone’s chemical structure
Explanation:
In living systems, chemical messengers called hormones are secreted into the body via the bloodstream or ducts by certain glands called endocrine glands e.g pancreas, hypothalamus etc. These hormones are meant to effect a physiological change in certain cells called TARGET CELLS.
In biology, a target cell is any receiving cell that has the ability to respond to signals and messengers like hormones. This responding ability of hormones is due to the possession of specific receptor sites for the specific hormones. The receptor on a particular target cell recognizes that specific hormone's chemical structure, hence, will only respond to it.
For example, an insulin hormone secreted by the pancreas will only be responded to by a target cell that recognizes the chemical structure of the insulin protein using its receptor molecule.
