Fungi because it’s basically the one I would pick
Answer:
They look like X's (X shape)
Explanation:
The X shape are replicated chromosomes and are called the sister chromatids.
Answer:
prokaryotic: A prokaryote is a single celled organism that does not have a nucleus or membrane bound organelled and its dna is in the cytoplasm. They also cant undergo mitosis because they dont have a nucleus. they are most likely to be unicellular
examples: archea and bacteria
eukaryotic:
A eukaryotic cell is an organism made up of cell that contain their dna in a nucleus. Eukaryotic cells contain membrane bound organelles as well as ribosomes.not all of them are the same though. mst of them are multicellular and go through mitosis
examples: fungi, plants, animals.
Answer:
Arrangement of the actin and Myosin filament
Explanation:
SACROMERE :An elastic membrane which serves for the *arrangement of the actin and myosin filament *
The fasciculi consist of still smaller bundles of elongated, cylindrical muscle cells, the fibre. Each fibre is a syncytium, i. e, has many nuclei. With the aid of an electron microscope, it can be seen that the muscle fibre is made up of smaller units, the myofibrils. Each myofibrils consists of small protein filaments known as *ACTIN and MYOSIN* filaments. The myosin filaments are slightly thicker and make up the darkband(or A-band). The actin filaments make up the light bands(I-band) which are situated on either side of the dark band. The actin filaments are attached to the Z-line.
During the contractions of skeletal muscle, the actin filaments slide inwards between the myosin filaments. Mitochondria provides the energy for this to take place. This action causes the shortening of the sacromeres(Z-lines move closer together, which in turn causes the whole muscle fibre to contract.This can bring shortening of the entire muscle such as biceps, depending on the number of muscle fibres that were stipulated. The contraction of the skeletal muscle is very quick and forceful.
