Desertification is the inability of ecosystems to fulfill their regulatory function caused by deforestation, overgrazing, and overworking the soil.
<h2>What is desertification?</h2>
Desertification is a phenomenon that implies the loss of fertile soils due to climatic variations and human activities.
- The three main causes of desertification are overgrazing, deforestation, and unsustainable agricultural practices.
- Overgrazing and deforestation destroy the protective vegetation layer that covers arid and semi-arid regions.
Therefore, we can conclude that desertification is the process of ecological degradation through which areas of land that were fertile and productive are transformed into deserts.

1)How does a hypothesis affect a scientific investigation?
You hypothesis is your prediction for what you're testing for, so it affects what experiment(s) you're going to do.
2) Detail the steps involved in designing an experiment.
Use the scientific method: Make a testable hypothesis. Design a study and collect data. Analyze results and reach conclusions. Communicate the results. Replicate the results.
3) what is the difference between an observation and a conclusion?
Observations are small details that you see during your experiment. Conclusion is the big idea that you get from your experiment.
Answer:
2
Explanation:
Humans need proteins, fatty acids, vitamins, and minerals
The lungs expand and with that you breathe in air as the diaphram contracts and relaxs to cause "breathing"
Answer:
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
Explanation:
If two heterozygous individuals have a child
i.e let the heterozygous individuals be = Xy
if both traits crosses together; their F₁ offspring will be; (XX, Xy, Xy, yy)
Xy × Xy
X y
X XX Xy
y Xy yy
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
