How many species of finch are in the Galapagos?
There are 13 recognized species of finches in the Galápagos Islands, often referred to as Darwin's finches. These species vary in size, shape, and feeding habits, which have evolved to adapt to the different ecological niches on the islands. Their diversity is a key example of adaptive radiation, illustrating how species can evolve from a common ancestor in response to environmental pressures.
The evolution of different forms in the same lineage when exposed to different selective pressures is called?
Adaptive radiation is the term used to describe the process of a single lineage giving rise to multiple diverse forms in response to different selective pressures in different environments. This phenomenon often results in the development of distinct adaptations and ecological roles within the same lineage.
How are finches on the Galápagos Islands a good example of adaptation?
Finches on the Galápagos Islands exemplify adaptation through their diverse beak shapes and sizes, which evolved in response to the varying food sources available on different islands. For instance, finches with larger, stronger beaks are better suited for cracking tough seeds, while those with narrower beaks can access insects and other smaller food sources. This adaptive radiation illustrates how environmental pressures can drive speciation and the development of specialized traits, highlighting the dynamic nature of evolution in response to ecological niches.
How many types of evolution are there?
well, you get many types like:australopithecus afarensisaustralopithecus africanushomo erectushomo habilishomo sapienhomo sapien sapien
A simile for The dogs response was as eager as a?
The dogs' response was as eager as a child on Christmas morning.
What is an example of an adaptive response?
A response to adapt to a situation...for example fear could create an adaptive response to "fight or flee", or could paralyze the person into inaction.
Specific immunological response?
adaptive immune response
Is Adaptive response is the accommodation of an individual organism to its environment?
True
What mobilizes the adaptive defenses and provokes an immune response?
Antigens
What is an advantage of a negative tropism?
An advantage of negative tropism, where a plant grows away from a stimulus such as light or gravity, is that it allows the plant to avoid unfavorable conditions. For instance, roots may exhibit negative phototropism by growing deeper into the soil to access moisture and nutrients, rather than towards light, which could indicate poor soil quality. This adaptive response enhances the plant's chances of survival and resource acquisition in challenging environments.
What part of the adaptive immune response involves B cells?
Humoral
What is an organism in action and change in the behavior that occurs as result of a stimulus is?
An organism in action and change in behavior that occurs as a result of a stimulus is known as a response. When an organism perceives a stimulus from its environment, it triggers a response that can be behavioral, physiological, or cognitive in nature. This response is an essential aspect of an organism's ability to adapt and survive in its surroundings.
Which cell of the immune system is absolutely required for an adaptive immune response?
T helper cells
What is the full form of AMR?
1) Adaptive Multi-Rate 2) American Medical Response
What is adaptive thermogenesis?
Adaptive Thermogenesis: This can be defined as the regulated production of heat in response to environmental changes in temperature and diet, resulting in metabolic inefficiency. For example, shivering when we are cold uses energy and this is an example of adaptive thermogenesis. (Alexander Bowring 24 / 04 / 2008)
What are the Advantage and disadvantage of innate immunity?
Advantage is that it gives a specific response. In a secondary exposure it responds so quickly you may not even feel sick. It is able to retain a long term memory against that specific pathogen as well. Disadvantage is that primary exposure it takes 1-2 weeks to start producing a response against a foreign pathogen. Also it is possible for your adaptive immunity to attack self cells, also called autoimmunity.
What does it mean to say that the adaptive immune response has "memory"?
When we say the adaptive immune response has "memory," it means that the immune system can remember specific pathogens it has encountered before. This allows the immune system to respond more quickly and effectively if the same pathogen enters the body again in the future.
