<span>Cilia and flagella are made up of microtubules covered by
plasma membrane and they projection from the cell. Thus, cilia are flagella are
motile and designed to move substances over or around the cell and they can as
well move the cell itself. In eukaryotes, they are conserved in their polypeptide
composition, structure and function as motile and sensory organelles.</span>
Answer: The correct answer for the blank is-
A) mitosis; meiosis
Mitosis is a type of cell division in which a parent cell produces two daughter cells with equal number of chromosomes as that of parent cell. It is essential in repair of damaged tissue and growth of living organisms. This is because body cells produce additional body cells with same genetic material.
Meiosis is another type of cell division that is specific to the sexually reproducing organisms. It is a reductional division as the diploid parent cell produces four haploid, reproductive cells ( called gametes such as eggs and sperms). This means that gamete formation in sexually reproducing organisms occurs through meiosis.
Thus, option A) is the right answer.
The wrong type for her baby.
The cell cycle is divided into the following five stages:
1. Interphase: The cell increase in size. The cell synthesize a complete copy of DNA in its nucleus.
2. Prophase: Chromosomes condense and are more visible. The nuclear membrane disappears. Centrioles separated at move to the opposite poles of the cell. Spindle fibers forms and radiate towards the center of the cell.
3. Metaphase: Chromosomes line up across the middle of the cell. Spindle fibres connect the centromere of each sister chromatid to the cell poles.
4. Anaphase: The centromere that join the sister chromatid split. Sister chromatids separate becoming individual chromosomes and moving to the opposite poles of the cell.
5. Telophase: Chromosomes uncoil. A nuclear envelope forms around each chromosome. Spindle fiber breaks down and dissolves.<span />
Answer:
As the fastest way to get ATP for muscle contraction, the phosphagen system is the predominant energy system used for races lasting up to 10 seconds. The muscles of sprinters like Maurice Greene, who has run 100 meters in 9.79 seconds, are great at producing ATP via the phosphagen system.
