Evidence for sea floor spreading

2 answers:

5 0

The rocks near the mid-ocean ridge were younger then rock near trenches. Matching bands of magnetic rocks were found on either side of the mid-ocean ridge; bands like tree ring - record changes in earths magnetic field over time. Earthquake data showed oceanic crust is sinking on to the mantle at trenches.

Answer: The evidences of seas floor spreading are as follows-

The sea floor spreading is taking place because of the constant plate tectonic movement.
The plates moves in opposite direction along the mid oceanic ridge, where new materials are added forming a new young crust.
The rocks that are found near the mid oceanic ridge are younger than the rocks that are found away from the mid oceanic ridge.
The alternating magnetic strips studied on the particles, observed on both the sides of the mid oceanic ridge are identical.

Match each biodiversity restoration method to its description.

serg [7]

Match each biodiversity restoration method to its description we have:

reforestation: using plants to absorb harmful compounds
biological augmentation: using plants to control a native plant population
bioremediation:using plants to increase biodiversity and food resources

<h3>What are ecological restoration techniques?</h3>

Some examples of induced ecological restoration methodologies are the conduction of natural regeneration, nucleation techniques, enrichment or diversity planting, among others.

In this case, the ecological restoration techniques are:

reforestation: using plants to absorb harmful compounds
biological augmentation: using plants to control a native plant population
bioremediation: using plants to increase biodiversity and food resources

The anterior portion of the body of most annelids, such as the earthworm, is adapted for sensing the environment.

Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are more abundant in the anterior portion of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:

Mechanoreceptors, disposed of in groups in each segment of their body.

Photoreceptors: Light-sensitive cells. Although they are located in the whole body, they are abundant in anterior and posterior segments, concentrated in the intern and dorsal part of the epidermis.

Humidity receptors are the most sensitive cells and are located in the first segments of the earthworm body

Chemoreceptors: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings in each segment but are especially abundant in the anterior part of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.
