Answer:
A.true
Explanation:
"""During their 150 million year existence, animals changed drastically in size, body, shape, and flying ability. a modification of an organism or its parts that makes it more fit for existence."""
Mixotroph organisms are capable of obtaining energy from the environment by combining autotrophic and heterotrophic mechanisms. Karenia brevis is <u>mixotroph</u>.
<h3>What is mixotrophy?</h3>
Mixotrophy is a nutritional strategy used by some organisms that combine autotrophy and heterotrophy to obtain energy. It is widely observed in aquatic environments and especially among phytoplanktonic flagellated algae.
The development of mixotrophy depends on the environment in which the organism lives, its limiting conditions, and resources availability.
This strategy is used in aquatic environments in which light and nutrients availability is scarce. So organisms can change from being autotrophs to heterotrophs, and vice-versa, according to the environmental pressures.
Karenia brevis, the dinoflagellate responsible for red tides, is _<u>mixotroph</u>_ , meaning it can undergo photosynthesis when conditions are right, or it can ingest bacteria, algae, and animal waste if additional nitrogen is needed.

Higher vascular plants contain catalase to metabolize Hydrogen peroxide (H2O2) in mitochondria and chloroplasts.
<h3>What is catalase?</h3>
Catalase is a key enzyme used by organisms to metabolize Hydrogen peroxide (H2O2), which is a reactive substance.
The animal tissues also contain catalase which they use to generate H2O and thus remove toxic H2O2.
In conclusion, higher vascular plants contain catalase to metabolize Hydrogen peroxide (H2O2) in mitochondria and chloroplasts
