The right answer here is option C. They occur in areas with ancient, mineral-poor soil.
An example of that is Amazonia in Brazil, it's one of the biggest forests on earth, and at the same time, we know its soil is poor, but at the same time it has some special materials that can be found there, such as niobium. This forest is, too, rainy almost all the time, and this many trees maintain the temperature of the whole earth stabilized. These kinds of forests can grow in this soil because of the burlap, that's organic materials from its own trees. It's consumed by them, and through this way, it survives and extends its size when humans don't use its resources too much.
Answer:
It controls gastrointestinal track.
Explanation:
The enteric nervous system supports the digestive system because enteric nervous system controls gastrointestinal track and there is no control of central nervous system (CNS) in this gastrointestinal track. Our gastrointestinal tract comprise of our mouth, esophagus, stomach, small intestine, large intestine, and anus. If abnormality occur in autonomic nervous system which result in negative impact on digestion because autonomic nervous system regulates digestion process.
Answer:
b. Feedback response
Explanation:
Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.
The correct answer is testosterone.
A chemical messenger simply refers to a hormone.
Testosterone is a lipid - based hormone. In fact, it is an anabolic steroid . Steroids are a type of lipid which has four rings of carbon atoms.
Testosterone is a hormone produced by the Leydig's cells in the testes, and which encourages the development male sexual characteristics such as deep voice, a beard, increased muscle mass and bone mass, and growth of hair on the chest.
The answer is meiosis.
In meiosis, this process produces 4 daughter cells which are all genetically different to each other and their parent cell. They have only half of the chromosomes. This is because, at one point in the process before the cells divide, parent do not copy their genetic information, which ends up each daughter cells only receiving half of the chromosomes after division.
The daughter cells are also said to be haploid, and in human, these cells are usually gametes, which are for reproduction, so that after 2 of these haploid cells join together, the correct amount of chromosomes can be restored.
