Let's break down each of the words to find out what they mean.
Eukaryotic: This basically means that the organism in question has a nucleus and other membrane-bound organelles. This rules out bacteria and archaea.
Multicellular: The organism must be made up of one or more cells, so that rules out protists.
Autotrophic: This means that the organism can make energy from inorganic substances via a light source or chemical energy. Finally, this rules out animals and fungi.
Cell wall: This also proves that the organism is a plant. Plants are the only organisms that have a cell wall made of cellulose; fungi have one, but they are made of chitin and glucans.
So, your answer is that the kingdom of the organism of a plant.
Under saturated or perhaps they are looking for hypotonic (remember 'hypo' rhymes with 'low' - for 'low' solute concentration).
Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
Answer:
It involves facilitated diffusion.
Explanation:
Facilitated diffusion uses channel proteins. Channel proteins allow substances to travel through a membrane going <em>with</em><em> </em>the gradient. Since active transport goes <em>against</em> the gradient, facilitated diffusion would not be a characteristic of it.
