<span>1.<span>Understanding life. Primarily, studying biology gives you the essentials
and primal knowledge of life and how and what you can perceive from it, may it
be various fields of zoology, botany or anthropology, psychology, sociology and
etc. It lets you understand the different anatomies, physiologies and
behaviours on how they act independently, interact and influence one another. </span></span>
<span>2.Protecting life. It provides a sense of preserving life as your upmost
goal in studying biology. You came to an actualization to delve into this science
as to be a steward and a developer.</span>
<span>
3.Responsibility. It comes with ethics. You become concerned with how
actions of a certain populace of a species can affect the entire ecosystem.
Human behavior has massive effects to the biosphere.</span>
<span>4.Advancement. The improvement and enhancement on how we can preserve and
understand life and the human populace develop and utilize the earth without
damaging its vital components.</span>
<span>5.Involve in the current issues and participate. You can be part of a
responsible scientist and individual, a citizen of science to stop and help grow
the serious concerns of today’s abusive human behaviours and life-threating concerns.</span>
Recall that apoptosis is programmed cell death—think of it as the cell deciding to self-destruct. So you might ask yourself, why would a cell need to die?
Remember that, in the cell cycle, there are certain checkpoints where a cell may stop and ensure everything is going smoothly. If something went wrong, the cell could potentially become cancerous, in which case it is much safer for a cell to undergo apoptosis rather than risk developing cancer.
Another example would be in the immune system. When cells get infected, cells called <em>cytotoxic t cells</em> go around and force these infected cells to undergo apoptosis in order to reduce the spread of infection.
Hope this helps!
i would say it means how would organisms would react in an ecosystem. think of everyday life in your backyard perhaps. the grass uses the energy from the sun to grow. another organism, lets say a horse, eats the grass as a main source of food. lets say another grass eater lives there too-like a cow. the cow and the horse would naturally compete as they both rely on the same food source, and the same living space that is close to that food source, and so on as you move up in the food chain.
