Answer:
Option-C
Explanation:
Habitat fragmentation is a process during which large habitat is fragmented in smaller habitats by man-made activities. Habitat fragmentation is a very harmful process as it is one of the major factors for the loss of biodiversity in the ecosystem.
Due to division of the larger habitat into the smaller fragments, the population present in the smaller area are more susceptible to extinction as they will not interbreed with the individuals of the population stuck in another small habitat.
Thus, Option-C is correct.
Answer:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
idk about 10, i can't see the diagram
11. The moment magnitude scale is one of many seismic magnitude scales used to measure the size of earthquakes." The scale was developed in the 1970s to succeed the 1930s-era Richter magnitude scale.
use that ^
Answer:
movement of chemicals into the dendrites of the neuron
Explanation:
Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.
Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.
An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.
