Answer:
The main difference is that EUKARYOTIC cells <em><u>have</u></em> a nucleus while a PROKARYOTIC cell <em><u>does not</u></em>. Instead, prokaryotes have free floating genetic material.
Explanation:
To help you remember this distinction:
EU = YES eukaryotes <em><u>HAVE</u></em> a nucleus.
PRO = NO prokaryotes <em><u>DO NOT</u></em> have a nucleus.
I hope this helps and good luck with your assignment.
True because, more variation increases the species fitness, the ability to survive and reproduce. Allowing the organism to pass on their beneficial traits (advantageous traits), to their offspring.
Answer:
In an ecosystem photosynthetic plants act as producers wheres other organism act as consumers.
Explanation:
Green plants undergo photosynthesis to produce their own food as a result they are called producers and are placed in the first tropic label of energy pyramid.
The other organism that intake green plants are called primary consumers for example grasshopper. The primary consumers are placed in the second tropic label of energy pyramid.
The other consumers are termed as secondary consumers or primary carnivores that feed on primary consumers For example Snake because it eats grasshopper and is placed in the third tropic label.
Finally the tertiary consumers or secondary carnivores consumes secondary consumers to intake energy from them.For example Hawk eats snake,as a result hawk act as secondary carnivores and are placed in the top of the energy pyramid.
Answer:
I just answered this same question for my Biology class hope this helps :)
Explanation:
A hydrogen bond is when positive and negative hydrogen forms together; this explains why cohesion sticks molecules together . Because of cohesion, the water molecules stick together and form a surface; this property is responsible for surface tension. Adhesion is the ability for water to stick to other substances; this helps with capillary action. Hydrogen bonding also explains why water's boiling point is higher than some liquid . With this, water has a high specific heat; this is because the water takes a lot of energy to raise (or lower) the temperature. Once again, hydrogen bonding is essential to another property. This property causes water to expand and to have a low density when frozen.
