Answer:
Cytoskeleton is the lattice-like structure of microtubules that support the cytoplasm and anchors organelles and also function in cytoplasmic streaming during cell crawling.
Explanation:
A group or network of protein fibers found within the cytoplasm is known as the cytoskeleton. It provides structural support for cells and is responsible for cell movement, cell stability, cell reproduction, cytoplasmic streaming or transportation of substances, etc. The movement of the cytoplasm within a plant or animal cell which helps to transport nutrients, proteins, and organelles within the cells is known as cytoplasmic streaming or protoplasmic streaming. The main three different types of protein-based filaments found in the cytoskeleton are microtubules, intermediate filaments, and microfilaments.
They are small, thick tubes made up of a protein called tubulin. They help to maintain cell shape and structure and are a part of the mitotic spindle which pulls homologous chromosomes apart during the cell division. The structures involved in cell movements such as cilia and flagella are also made up of microtubules. They help to resist the compression of the cell, provide pathways for secretory vesicles to move through the cell and also have a role in positioning the organelles within the cell.
They are thin filaments made up of a strong and flexible protein called actin. Actin filaments along with the protein myosin are responsible for cell movement and muscle contraction. Both proteins also have a role in splitting of a parent cell into daughter cells during cell division.
Their thickness is intermediate between the microfilaments (thinnest structure) and microtubules (thickest structure). They are made up of a protein called keratin and provide structure to the nuclear envelope and help anchor organelles together within a cell. Intermediate filaments along with the microtubules help to maintain cell shape and structure. They help to resist the tension of the cells and also link cells to other cells.
Answer:
steroids: catabolic
cellular respiration: catabolic
lipid breakdown: catabolic
photosynthesis: anabolic
Explanation:
Catabolic you could say is when something breaks down, "consumed, used". When its anabolic its being formed, example: photosynthesis to create energy.
Hope that helps
Answer:
Option A, a fitted shirt with short sleeves
Explanation:
Any kind of loose clothes or clothes with flammable material can easily catch fire. Also any cloth that can easily detach from the body such as loosely wrapped scarf, open platform shoes etc. must be avoided as they can add to the fire problem.
In fact Kim should wear tight clothes that in no way comes in contact with the fire. Also as a precautionary measure he must wear lab coats and goggles.
Hence, option A is correct
35 year old Lucy needs to have her blood taken. She is so distraught by this that she must mentally prepare herself for it as well as take short-acting sedatives. What does Lucy seem to be suffering from?
