Cell metabolism fluctuates throughout the day in response to the body's circadian rhythm. Metabolic processes such as glucose utilization, energy production, and hormone secretion are typically higher during the day to support activity and lower at night during rest. Disruption of this rhythm, such as through shift work or irregular eating patterns, can affect metabolism and overall health.
Acetyl CoA can be used in cellular metabolism to produce energy through the citric acid cycle or to synthesize fatty acids. It can also be converted into ketone bodies in times of fasting or low carbohydrate intake.
Different types of flowers have evolved to bloom at different times of the year to increase the chances of pollination and reproduction. By blooming at different times, flowers can attract specific pollinators that are active during that particular season, ensuring successful reproduction and genetic diversity within the plant species. Additionally, blooming at different times can help reduce competition for resources such as sunlight, water, and nutrients among different plant species.
Ketones are produced in the body when there is a shortage of glucose for energy. They are an alternative fuel source that can be used by the brain and muscles during times of low carbohydrate intake or fasting. Ketones play a key role in metabolism by providing energy to cells when glucose levels are low, helping to maintain energy balance in the body.
Multicellular organisms, however, typically go through a process called development. During development, a single fertilized egg cell divides again and again to produce the many cells of mature organisms. As those cells divide, they change in shape and structure to form cells such as liver cells, brain cells, and muscle cells. This process is called differentiation, because it forms cells that look different from one another and perform different functions.
Genes located in different regions of the body during embryonic development may be turned on and off, activated for different times in different cells. This dynamic regulation helps to control cell differentiation and tissue formation.

Hair can indeed fall out more at different times of the year. This is largely due to diet changes or activity changes brought on by different seasons.
A record of its positions at different times.

Metabolism can speed up during adolescence. This is one of the times during a life cycle where the metabolism works faster.
In 1925, George Durning played in 5 games, batting in all of them. He had 14 at bats, getting 5 hits, for a .357 batting average, with 1 runs batted in. He was walked 2 times. He struck out 1 times. He hit only singles.
the colour of your grass changes when it is different times of the year.
Ever so slightly, you proably wouldn't recognize the changes though.
Because blood pressure changes.
Earth moves around the Sun. As a result, the apparent position of the Sun in the sky changes.
Natural selection is something that happens over time and is somewhat dependent on the conditions of climate and environmental changes. There are times when natural selection can favor different phenotypes, if and when the culture starts to seek out others with certain traits and characteristics to breed.
Constellations appear to be in different places at different times due to the Earth's rotation on its axis. As the Earth rotates, the position of the observer relative to the stars changes, causing different constellations to become visible. This is why different constellations can be seen in the night sky at different times and in different locations on Earth.
