The answer I believe is now b)2+ because if you so the add and subtract in this you will get 2+
Answer:
The correct option is C. The level of organization best represented by the corn plant is : organism, the level of organization directly above organ system organ system
Explanation:
An organism can be described as a living thing made up of organ systems.
Plants are organisms that have levels of organizations similar to animals. Cells in plants make up tissues. There are mainly two types of tissues in plants: the meristematic tissue and non-meristematic tissue.
Just like animals, plants have organ systems. There are two kinds of organ systems mainly in plants: the shoot system and the root system. Hence, option C is the correct option.
Assuming we know nothing else about the properties of lithium when looking at the periodic table we can see Li is a pretty lightweight element. This could be very useful when making batteries
<h3>Answer:
234 90Th → 0 -1e + 234 91Pa Explanation:
Given that :
Thorium 234 decays by beta emission Beta emission = 0, - 1 e
234 90Th → 0 -1e + 234 91Pa Hence, when Thorium 234 90 undergoes a beta Decay ; mass number remains the same at 234 while atomic number increases by 1, becoming (90 + 1) = 91 to form a protactinium nuclide.
