Hey there!
We CAN use the periodic table to determine which atoms are most likely to lose or gain electrons during the formation of an ionic bond
True
Hope this helps!

Answer:
Dementia
Explanation:
Dementia is a condition that involves impaired mental ability and memory which is common among older adults. This condition, which is a major contributor to disability and placement of older adults in nursing homes, can be as a result of several factors of which nutrition has a major role to play. Metabolic and endocrine problem that results to the inability of the body system to regulate nutrients such as calcium and vitamin B-12, are some of the factors that triggers dementia in older adults. Also, nutritional deficiencies such as dehydration, inadequate intake of vitamin B-1, vitamins B-6, copper,vitamin E, and vitamin B-12 increases the chances of developing dementia in older adults.
Research shows that low levels of vitamin D can be linked to increased risk of developing dementia, and as such, supplements such as B-complex vitamin, vitamin C, and vitamin D is usually recommended for the prevention of dementia, especially when they are deficient in the diets taken.
Answer:
4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work
Explanation:
Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.
The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.
Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.
Extinction of species reduces the number of different species in ecosystems, hence lowering the diversity of living things.
