because they've had mor cells duplicate and reproduce
The primary difference between old people's cells and young people's cells lies in their functionality and regenerative capacity. As people age, their cells undergo changes such as telomere shortening, increased oxidative stress, and a decline in the ability to repair DNA, which can lead to slower healing and less efficient cellular processes. Young cells typically exhibit better growth, division, and repair mechanisms, allowing for more effective responses to injury and stress. Additionally, older cells may accumulate more senescent cells, which can negatively impact surrounding tissues and overall health.
Mostly because they are weaker, if white blood cells its because they have probably been fighting off infection, but if red blood cells it is because they have been worn out from caring nutrition.
Older people tend to heal more slowly due to age-related changes in their skin, reduced collagen production, decreased efficiency of the immune system, and slower cell regeneration. Additionally, older individuals may have underlying health conditions that can also impact their healing process.
Prokaryotes are considered older because they appeared in the fossil record earlier than eukaryotes. It is believed that the simpler structure of prokaryotic cells made them better suited for survival in the early Earth conditions. Eukaryotic cells with their complex internal structures evolved later.
OIder bacteria cells are decolorized more easily than younger cells, because as cells age their cell walls become "leaky" and allow molecules to pass more readily out of the cell. In gram stain, the crystal violet-iodine complex is more readily lost during the decolorization step.
Older people need 31 grams a day. So it is older people.
I think maybe for one because there are more babies available versus more older children here and also I think it is easier to adopt in other countries than it is here.
because maybe more people were still able to have babies at an older age
Yes.
The development of newborn babies differs from that of older infants and children in terms of physical growth, cognitive abilities, and social interactions. Newborn babies primarily focus on basic reflexes and sensory experiences, while older infants and children show more advanced motor skills, language development, and social interactions. Additionally, newborn babies require more care and support for their basic needs, while older infants and children become more independent and self-sufficient over time.
More people making more babies.

bones do not stretch; they grow by building more cells.
The more people the more married, the more babies, the more people, the more marrid ect.. Yes, you are.
As of 2021, there are more younger people globally than older people. However, the proportion of older people is growing due to increased life expectancy and declining birth rates in many countries.
As the body ages, the mechanisms which correct errors made during DNA replication become less efficient. This leads to more errors, which leads to more mutations, which in turn can lead to more rogue cells which can become cancerous.
It is believed that what occurs is new skin cells are produced at a more rapid pace than the dead cells are being discarded.
