Genetic variance increases the chance of survival because through an enlarged gene pool, the chances of successful mutations is higher, as well as the favoring of successful traits.
An example of this is in birds, some species with large gene pools in a single geographic location will favor males with longer tail feathers, therefore that trait will become more common and increase the chance of survival through improved genetics within offspring.
Cross bridges are created when myosin heads bind to (actin).
like climate change, can permanently alter an ecosystem, but over time the change may cause some
[Genetic variations] to become more favorable or less favorable in the new environment. If adaptations to the new environment are not present or do not develop, populations can become [extinct.]
B. The electron transport chain. The electron transport chain produces around 34 ATP molecules and the other 2 only produce around 2 ATP molecules.
Answer:
B cells are at the centre of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens (typically known as antibodies).
Explanation:
T cells are a part of the immune system that focuses on specific foreign particles. Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen. As such, T cells play a critical part in immunity to foreign substances.
