Hello There!
This is a false statement. Ecosystems don't have trouble adjusting to short-term changes.

Answer:
Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;
Presence of Exoskeleton.
The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.
Varied habitats.
Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.
Bilateral Symmetry.
Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.
Jointed Legs.
Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.
Short generation time.
Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.
Reproduction strategy.
Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.
Segmented body.
Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.
Answer:
<em>The correct option is mudflow.</em>
Explanation:
Mudflow can be described as a flow of water which contains large amounts of silt present in it. Mudflow is generally known to occur in areas where there are steep slopes. Mudflow can cause extreme damages to people in those areas as well as their properties. Mudflow usually contains 60% water and the rest is silt and suspended particles submerged in it. Due to the particles, it has a high viscosity due to which it does not flow as water flow.
When cancer cells enter the lymph or blood system, they can form secondary tumours elsewhere.
<span>Secondary tumours are actually metastasis, cancer that spreads to a different part of the body from where it started. This happens when cancer cells break away from the main tumour and travel via blood or lymphatic system to other certain parts of the body. It is more difficult to treat metastasis because it is not always the same type of an original tumour.</span>
