Answer and Explantion

Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.

Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.

Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.

Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.

How do pioneer species make ecological succession possible on an island formed from a volcanic eruptions
SIZIF [17.4K]

Answer:

The correct option is <em>3. they break down rock into soil in which plants can grow</em>

Explanation:

When a disaster is such huge that even the soil and organic matter get removed from the place, then the succession that will occur in such kind of place will be termed as primary succession. For example, a volcanic eruption or an earthquake.

On the other hand, if after a disaster some of the organic matter remains on the land, then the succession that will occur will be termed as secondary succession. E.g a succession after fire

In primary succession, the pioneer species will be plants that require less soil such as the lichens. The lichens will break down the rocks into the soil and eventually new species of plants will start to grow on the land.

DaniilM [7]

Answer:

Intermediate Product Accumulation

Explanation:

If one of the crucial enzyme say B is mutated in the process of normal product formation, then the reaction will not proceed further from that point and accumulation of an intermediate product in the cell takes place. The mutation in the enzyme could be environmental or genetic but it will surely alter the enzyme functioning. In the end, the damage malfunctioning cell will be removed using the process of apoptosis.
