They have the maximum possible number of electrons in their outermost shell.
Answer:
They have the maximum possible number of electrons in their outermost shell.
Explanation:
There are only a few elements that are less reactive than noble gases. The reason for this is that they are filled with electrons, which are referred to as valence electrons.
Essentially, the more electrons on the outermost shells, the less reactive.

Anna runs 5 km in 20 minutes. What is her speed in kilometers per hour?
Answer:
15 km/h
Explanation:
5 km in 20 min
5km is 5000m and 20 min is 20×60 =1200s
5000÷1200= 25÷6 m/s
To convert m/s to km/h we multiple by 18/5
25÷6×18÷5
15 km/h.

Blood glucose begin to increase after a meal. As a result, glucagon levels must _________ while insulin levels must ________ in order to maintain metabolic homeostasis.
If glucose begin to increase after a meal, glucagon levels must decrease while insulin levels must increase in order to maintain metabolic homeostasis.
What is homeostasis?Homeostasis is the process by which a stable internal environment is maintained irrespective of the changes in external conditions.
The regulation of sugar level in the blood is one of the homeostatic responses. Insulin and glucagon are two hormones used to perform this task of blood sugar regulation.
Insulin is an hormone that reduces blood sugar level by stimulating the conversion of excess sugar to glycogen.Glucagon, on the other hand, increases blood sugar by converting glycogen back to sugar.Therefore, if glucose begin to increase after a meal, glucagon levels must decrease while insulin levels must increase in order to maintain metabolic homeostasis.

What material is too important to ever leave the nucleus? A. DNA B. Protein. C. Ribosomes D. Chromosomes
A. DNA is too important to ever leave the nucleus.
DNA material is too important to ever leave the nucleus. Hence the correct option is A.
DNA (Deoxyribonucleic Acid) is a crucial molecule found within the nucleus of cells. It carries genetic information and instructions necessary for the growth, development, functioning, and reproduction of living organisms. The information encoded in DNA determines an organism's traits, characteristics, and overall biological processes.
DNA's essential role in inheritance and cellular activities makes it too important to ever leave the nucleus. While other cellular components like proteins, ribosomes, and chromosomes are important, DNA is the primary genetic material that must remain securely stored within the nucleus.
Hence the correct option is A.
