Third trimester. It doubles in mass at this time and continues to still grow and mature
Hello!
Social interactions may help lower the risk of Alzheimer's disease by the brain constantly working behind the scenes.
So like when, a person is socially interacting, they are using their mind even if they don't notice. Someone in the beginning stages of Alzheimer's will not remember a lot of details about their lives. However, socially interacting may be able to bring back memories that will trigger the brain to remember the details they had forgotten.
So ''by helping keep a person's mind active'' is the correct answer.

Answer:
c2h4o
Explanation:
empirical formula is simplest whole number ratio of atoms in molecule
SINCE RATIO OF C,H O IS:
C : H : O
4: 8 :2
SIMPLEST RATIO ( DIVIDING BY 2)
2: 4: 1
C2H4O
Answer:
The correct answer is b. glucose is low and lactose is present
Explanation:
Lac operons are found in bacteria and it contains one regulator gene, one promotor sequence, one operator and three structural genes. When lactose is not present in the environment regulatory gene synthesizes repressor proteins that bind to the operator and stops the expression of the lac operon.
When lactose or allolactose is present then it binds to repressor proteins and prevents the protein to bind to the operator region which results in the expression of the lac operon. So to express lac operon lactose should be present.
In presence high amount of glucose lac operon is not expressed because glucose is the easy source of getting energy than lactose so for expression of lac operon glucose should be low and lactose should be present.
