Answer: B. The number of individuals that a habitat can sustain with the resources that it has available.
Explanation:
A carrying capacity is the number of individuals of the population belonging to a particular species that an habitat or region or ecosystem can support or sustain in terms of providing the resources. If the population exceeds over the carrying capacity then this results in decline in members of the population.
According to the above description the accurate definition of carrying capacity is B.
Darwin's proposed mechanism for evolution is natural selection. Natural selection allows species to respond to their surroundings through time, or to become progressively excellently-suited. Natural selection is environmentally based and involves established heritable variation within a population.
They lead to changes in species over time:
- Darwin suggested species will evolve over time, new species originate from pre-existing species, and all species share a common ancestor with each other.
- In this framework each organism has its own special set of heritable i.e genetic variations from the common ancestor that have slowly developed over very longer periods of time.
- Parroted branching activities that isolate new species from a common ancestor create a multi-level tree that connects all living organisms.
Cyanobacteria were very simple organisms and performed were an role in changing Earth's early atmosphere. They carried out photosynthesis to produce the materials they needed to grow. In this process, they release Oxygen which is needed to sustain life on Earth for Humans and other organisms.
Answer: The correct option is C (Dendrites, Cell body, Axon, Axon terminals)
Explanation:
The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called NEUROTRANSMISSION.
The order of neurotransmitter/receptor interaction that results in an electrical signal impulse and the release of another neurotransmitter for interaction in the synaptic cleft (signal conduction through a neuron) is from Dendrites--> Cell body--> Axon-->Axon terminals>
DENDRITES extends from the cell body of a neurone to receive messages at neuromuscular junction from other neurons. The CELL BODY directs all activities to the axon. The AXON is a long single fibre that transmits messages from the cell body and ends in terminals forming a synapse. Nerve impulses arrives at the axon terminal causing the release of neurotransmitters. The neurotransmitters binds to receptors at the dendrites of another neurons. The electrical signal impulses generated causes the release of neurotransmitters in another neuron.
It was the trip that Charles Darwin went on in attempt to find the answer of how animals got on earth in the first place and how they changed over time. This later on helped him discover evolution and natural selection. The most significant find on this voyage was that he found that different types of finches evolved to the food around them. Smaller beaks meant the finch ate more small nutrients but larger beaks meant the finch ate more harder prey such as fish and worms.
