Birds and most land and water animals get along. the birds clean the bugs and old mean off of most animals and that gives them food for babies. but birds are pray to.
Hey there!
An ion is any atom with an electric charge. This can be negative or positive.
To see which one of these is an ion, first see what causes an electric charge. Positive charges are caused by protons. One proton = one positive. Negative charges are caused by electrons. One electron = one negative. Thus, when the number of protons and electrons are equal, this makes it so there is no overall charge. Thus, to make an ion, the number of protons and electrons must be unequal.
When we look at the answer choice, we can see that the number of protons and electrons are equal for every single choice except for choice b. Thus, your answer is b.
Hope this helps!
Few advancements in scientific knowledge were made.
Scientists discovered new evidence to support their theories.
Scientists used observations and mathematical data to solve problems in new ways.
<u>Explanation:</u>
At first the Ptolemaic model suggested that the earth was the centre of the solar system around which the sun, moon and other planets revolved. This Copernican revolutionised by finding Sun in the centre of the solar system around which the earth and the other planets revolved. After his discovery the earth was just given a status of yet another planet.
The scientists who were researching on this made few advancements using their scientific knowledge and hence found new evidences to support their theory. Scientists then researched conducted experiments using mathematical calculations to solve their problems.
The false statement is: Growth hormone is produced by the posterior pituitary
Growth hormone (GH) or somatotropin is produced in the cells called somatotrophs of the anterior pituitary gland. GH is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration. Its function is involved in metabolic processes (favors anabolism or synthesis of macromolecules). Also, growth hormone stimulates production of IGF-1 and increases the levels of glucose and free fatty acids.
