Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.
<u>Answer:</u>
<em>Climate change positively affects organisms by </em><em><u>providing them new habitat.
</u></em>
<u>Explanation:</u>
Climate change induces <em>changes in various parameters of an ecosystem </em>like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in.
But this <em>new conditions</em> may be favourable for some other kind of organisms to thrive and flourish.
<em>For example, </em>when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of <em>native cold water organisms of the lake. </em>
Thus climate change doesn’t bring any benefits to living world without harming one or the other <em>group of organisms.

Answer:
a. add more of the enzyme.
Explanation:
Enzymes speed up the rate of reaction by lowering the activation energy for the reaction. They are not used themselves in the reaction. They are specific to substrate molecule. Substrate molecule binds to enzyme's active site and they undergo the reaction to form the product and release back the enzyme.
Rate of reaction depends on both substrate and enzyme concentration. Maximum rate of reaction is reached when all the active sites of enzyme molecules have been occupied by the substrate molecules which means that they are saturated. If more substrate is added at this point it wont have any effect on rate of reaction since there are no free active sites. Hence more enzyme is required to be added so that extra substrate can be utilized and rate of reaction can further be increased.
