There is no chart. I’ll tell you a song that tells the elements in order.
There's Hydrogen and Helium Then Lithium, Beryllium Boron, Carbon everywhere Nitrogen all through the air With Oxygen so you can breathe And Fluorine for your pretty teeth Neon to light up the signs Sodium for salty times MAGNESIUM, Aluminum, Silicon, PHOSPHORUS Then Sulfur, Chlorine, and Argon POTASSIUM and Calcium so you'll grow strong SCANDIUM, Titanium, Vanadium and Chromium and MANGANESE This is the Periodic Table Noble Gas is stable Halogens and Alkali react aggressively Each period we'll see new outer shells While electrons are Added moving to the right Iron is the 26 then Cobalt Nickel coins you get Copper, Zinc, and Gallium Germanium and Arsenic Selenium and Bromine film While Krypton helps light up your room Rubidium and Strontium Then Yttrium, Zirconium NIOBIUM, Molybdenum, Technetium RUTHENIUM, Rhodium, Palladium SILVER-WARE then Cadmium and Indium TIN-CANS, Antimony then Tellurium and Iodine and Xenon and then Caesium and Barium is 56, and this Is where the table splits Where lanthanides have just begun Lanthanum, Cerium and Praseodymium Neodymium's next to Promethium then 62 Samarium, Europium Gadolinium, and Terbium Dysprosium, Holmium, Erbium Thulium, Ytterbium, Lutetium HAFNIUM, Tantalum, Tungsten Then we're on to RHENIUM, Osmium, and Iridium PLATINUM, Gold to make You rich 'till you grow old MERCURY to tell you When it's really cold THALLIUM and Lead then Bismuth for your tummy POLONIUM, Astatine would not be yummy RADON, Francium will last a little time RADIUM then Actinides at 89 This is the Periodic Table Noble Gas is stable Halogens and Alkali react aggressively Each period we'll see new outer shells While electrons are to the right Actinium, Thorium, Protactinium Uranium, Neptunium, Plutonium Americium, Curium Berkelium, Californium Einsteinium, Fermium, Mendelevium, Nobelium Lawrencium, Rutherfordium Dubnium, Seaborgium Bohrium, Hassium then Meinerium, Darmstadtium Roentgenium, Copernicium Ununtrium Flerovium Ununpentium Livermorium Ununseptium Ununoctium And then we're done
Answer: The blanks can be correctly filled up with prophase I and metaphase II.
Explanation:
In females, finite number of oocytes are present since birth. The process of oogenesis initiate in embryonic stage only. However, oogonia divide and mature to form primary oocytes. These primary oocytes start meiotic division but arrest in prophase I stage before birth.
After a girl attains puberty, one primary oocyte resumes its division each month during a menstrual cycle. The primary oocyte divides to form secondary oocyte and polar body.
Polar bodies degenerate after completing meiosis II. However, secondary oocyte halts its division again at metaphase II until fertilization takes place. Once fertilization takes place it completes its meiosis II and results into mature ovum and polar body.
The right answer for the question that is being asked and shown above is that: "all of the above." Echolocation is an adaptation bats use to hunt insects in flight; locate flowering plants; <span>find warm places for hibernation</span>
The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and mitosis (M) phase.
DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.
The number of chromatids restores to 2n in daughter cells after completion of mitosis.
Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.
Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.
