mention two patterns seen in the periodic table
Answer:
Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.
Elements that have similar chemical properties are grouped in columns called groups (or families). As well as being numbered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements).

A student in your class made the claim that when animals eat fruits from plants, they harm the plant and threaten its survival. Use evidence and scientific reasoning to refute the claim made by the student.
Answer:Msg me bruv
Explanation:
When animals eat plants, they indeed cause a shortage of plants, but only for a small period of time.
Because when they excrete, the plant particles help grow into a new plant.
And when they die too, this happens.
And the nitrogen cycle also gets renewed because of this factor.
SO, because of these all reasons, instead of telling the animals are threatening the existence of plants, it will be more reasonable to say that they are helping plants in their growth.
Thank You
