An exosystem is a system or environment that surrounds a child and has a high influence on the child's development; however, the child is not directly involved with with the environment. In order to examine exosystems more closely, one may visit places such as medical centers or religious institutions because both of these affect the development of a child's thinking process.
Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
Answer:
Genes
Explanation:
The information to make proteins is in the DNA. The proteins are each coded for by the specific section of the DNA called a gene. A gene is required to make a protein.
Place mercury in the reactor. After a large amount of work, only a tiny portion of gold is created.
Decontaminate the resulting gold. This is harder than it sounds because you can't separate out non-radioactive gold from radioactive gold using purely chemical methods.
It should be obvious from this process that it currently costs much more money to create non-radioactive gold than you could ever earn by selling the gold. Creating gold from other elements is currently an expensive laboratory experiment and not a viable commercial activity. Perhaps technology will improve enough in the future to make creation of gold in nuclear reactors a profitable economic enterprise.
Answer: The correct ground-state electron configuration:
Explanation:
According to Aufbau rule :
The electron will first enter in the orbital with the lowest energy and after occupying the orbital with lower energy is goes top higher energy orbital.
The energy of the orbital is given by: (n+l)
For example: 1 s =(1+0) = 1, 2s = 2 + 0 = 2, 2p = 2 + 1= 3 etc.
So, the order of the orbitals with increase in energy is:
1s<2s< 2p<3s<3p <4s <3d<4p<5s<4d<5p<6s<4f< 5d<6p<7s<5f<6d<7p ....so on.
So, from the given option the correct ground-state electron configuration:
