A commensalistic relationship is one sides but neutral for the other party. Barnacles live on whales but whales are not directly affected by them. I do not believe the barnacle population decrease would affect whales at all.
Mitosis
begins with interphase ends with telophase
occurs in haploid cells
results in 2 identical sister cells
and c it splits into even numbers of chromosomes
meiosis
begins with interphase 1 and ends with telophase 2
occurs in diploid cells
results in a haploid
and 4 one diploid cell into 4 haploid cells
Cytoskeletal filaments provide the basis for cell movement. For instance, cilia and (eukaryotic) flagella move as a result of microtubules sliding along each other. In fact, cross sections of these tail-like cellular extensions show organized arrays of microtubules.
The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition.
Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a diameter of only about 6 nm, and they are made of a protein called actin. Intermediate filaments, as their name suggests, are mid-sized, with a diameter of about 10 nm. Unlike actin filaments and microtubules, intermediate filaments are constructed from a number of different subunit proteins.
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Answer:
Extinction is the natural process by which species die off.
Answer:
some manufacturers are kind enough to put wattage information on the front of their appliances. And others put it on a small sticker on the inner part of the door or on the back of the oven.
