<span>The answer is A) DNA.
The genetic information of the cell is packed within a nucleus. Unlike other organelles of the cell, chloroplasts and mitochondria have their own genetic information as well in the form of DNA. Mitochondrial DNA is circular in most of the organisms, only some protists, fungi and plants have linear mitochondrial DNA. It contains genes that code for transport RNA, ribosomal subunits, and for other proteins necessary for mitochondrial function. Chloroplast DNA has branched linear form. Chloroplast genes mostly code for proteins involved in photosynthesis.</span>
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
Explanation:
Answer:
Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>
Explanation:
MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.
For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.
Answer:
The correct answer is B.
Explanation:
Mitosis usually results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
The sea affects the climate of a place. Coastal areas are cooler and wetter than inland areas. Clouds form when warm air from inland areas meets cool air from the sea. In the summer, temperatures can be very hot and dry as moisture from the sea evaporates before it reaches the centre of the land mass.
