Yes, protists have cell walls.
Protists cell walls are made of composed cellulose, protein strips , and silica
For some protists, we can even found components like pectin on the cell walls
hope this helps
Answer:
There are many questions that can be answered by science but I will provide some examples below.
Explanation:
Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.
In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:
Biology
<em>How does climatic phenomena, such as El Niño and La Niña, affect the migration of whales?</em>
<em />
Neuroscience (humans)
<em>Is schizophrenia hereditable?</em>
<em />
Behavioral Ecology
<em>Does climate change affect the capability of cuttlefish to camouflage?</em>
Neuroscience (Animals)
<em>Are killer whales capable of problem-solving?</em>
<em />
Ecology
<em>How does the reduction of apex predator populations (terciary consumers) affect the population of secondary consumers?</em>
<em />
Conservation Biology
<em>Why do increased temperatures lead to coral bleaching? What is the mechanism and how can it be controlled?</em>
<em />
Animal Behavior
<em>What is the mechanism that Ophiocordyceps unilateralis (Zombie fungus) uses to manipulate ants for its own disperal?</em>
<em />
Parasitology
<em>Does the parasite Toxoplasma gondii induce erratic behaviors in humans?</em>
I think it’s B I’m not for sure
Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.
Answer:
What system interacts to perform the functions of regulation?
Body systems interact to perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness
