I don't understand ur question. Hmm
An aloe vera plant possessing a trait for extra thick leaves survives very long droughts in deserts, while and aloe vera plant that doesn't have thick leaves doesn't.
Answer:
May not
Explanation:
Adaptation is made possible as a result of an organism being exposed to different environmental conditions. These exposure makes it adopt different techniques for its survival which eventually results in it being adapted to the condition and is then passed on as traits to its offsprings. They are then able to survive when met with such environmental condition.
When an organism is exposed to the same conditions all the time then there is lack of genetic variation and adaptation may not occur.
state the uses of excretory products in plants
Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants. Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration.

Answer:
1. Cinder cones
2. All of these
Explanation:
1. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).
2. Volcanic Explosivity Index (VEI) is a numeric scale that measures the relative explosivity of historic eruptions. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The Volcanic Explosivity Index (VEI) was derived to catalogue the explosive magnitude of historical eruptions, based on the order of magnitude of erupted mass, and gives a general indication as to the height the eruptive column reached.
Hope this helps!
