Answer:
una comunidad similar de los mismos organismos y su entorno físico.
Explanation:
Buena pregunta.
Phototropism is when a plant moves towards the sun. Geotropism deals with gravity. It is the turning or growth movement by a plant in response to gravity. This helps the plants roots go deeper ir grow in different directions to find water.
Answer:
The correct answer will be- primary motor cortex
Explanation:
The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain. The motor cortex is thought to be involved in the planning actions and control voluntary actions.
The motor cortex is divided into three regions: premotor cortex, primary motor cortex and supplementary motor area.
The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.
Thus, the primary motor cortex is the correct answer.
Answer:
Answer 1:
Seismic waves, the waves of energy that travel through the Earth as a result of an earthquake can tell us a lot about the internal structure of the Earth because these waves travel at different speeds in different materials. There are two types of waves that travel through the Earth: p-waves and s-waves.
P- waves are faster and they can travel through both solids and liquids. S-waves are slower and cannot travel through liquids. For both kinds of waves, the speed at which the wave travels also depends on the properties of the material through which it is traveling.
Scientists are able to learn about Earth’s internal structure by measuring the arrival of seismic waves at stations around the world. For example, we know that Earth’s outer core is liquid because s-waves are not able to pass through it; when an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive. Similarly, we know that the earth has a solid inner core because some p-waves are reflected off the boundary between the inner core and the outer core. By measuring the time it takes for seismic waves to travel along many different paths through the earth, we can figure out the velocity structure of the earth. Abrupt changes in velocity with depth correspond to boundaries between different layers of the Earth composed of different materials.
Explanation:
Abiotic factors composed of water, light, temperature and air etc. due to fire's this primary succession was completely destroyed. Their remaining organic bodies were decomposed in soil texture.
In order to establish secondary succession there is need of water and light, because water help in translocation of food and nutrients in plants while light is important for photosynthesis.
Photosynthesis need three major components. these are H₂O, CO₂ and light, all these components are abiotic part of ecosystem. However, when secondary succession occurs, then light play a key role in changing the composition of plant community. The best example is the difference in height of plants of different community.
