1. What is a Eukaryote?2. What are metazoans?3. List and DEFINE the characteristics of Animals: a.

Eukaryotes are organisms whose cells have a well defined nucleus. The nucleus is tightly packed together within membranes. Eukaryotes are usually complex organisms with a high level of specialization. Examples include humans and animals.

2. Metazoans- They are also known as multicellular animals. They are Eukaryotes with a high degree of specialization and body functions. They lack chlorophyll and feed on other organisms for food and as a source of energy.

3. Movement- Animals don’t have a fixed spot. They have legs or other specialized structures for movement in search of food or to avoid predators.

Respiration- Animals respire through special structures which takes in Oxygen and releases Carbon dioxide back into the atmosphere.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
