Answer: C. Microfilaments
Explanation: Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell. Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell.
Out of the following given choices, the answers are;
morning stiffness in joints

Hello I have an assignment to do in svt I must answer the following questions: To) from the observation you make of calcite and aragonite crystals and from their molecular models, these minerals crystallize-old in simple cubic or face-centered cubic structures. Justify the answer.
B) find living organism structures made up of these crystals. Draw a conclusion on this observation.
C) We consider documents 1 and 2 above.
Give an explanation of the different properties of these crystals of the same chemical composition.
I cannot answer these questions. Can you help me please
The single-celled organism in the given case is prokaryote.
A prokaryote is a unicellular species, which is devoid of a membrane-bound nucleus, mitochondria, or any other kind of membrane-bound organelle. Prokaryotes are differentiated into two domains Bacteria and Archaea.
Bacteria are prokaryotes that comprise a single cell with a basic internal composition. Bacteria are microscopic single-celled species, which live in different surroundings. Archaea are also prokaryotes, that is, devoid of the nucleus.
Archaeal cells have unique characteristics, which distinguishes them from the other two domains of life, Eukarya, and Bacteria. They are also known as extremophiles, that is, possessing the tendency to thrive in extreme environments, like salt lakes and hot springs, they are also found in a diverse range of habitats.
