Answer:
a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.
b) The expected phenotypic classes in the F2 are: 9:3:3:1
9/16 R-B-, 3/16 rrB-, 3/16 R-bb, 1/16 rrbb
Proportions 9:6:1.
9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)
Explanation:
<u>Available data:</u>
- brown kernel: R-bb or rrB-
1º Cross) RRBB x rrbb

F2) Phenotypic classes:
<em>9/16 R-B-</em>
<em> 3/16 rrB-</em>
<em> 3/16 R-bb</em>
<em> 1/16 rrbb</em>
Phenotypic proportions:
<em>9/16 Red kernel (R-B-)</em>

<em> 1/16 White kernel (rrbb) </em>
Answer:
Centrioles are located near the nucleus and help organize cell division.
Which of these list of elements would complete the chart? A) C, H, O B) C, H, O, N C) C, H O, N, P D) C, H, O N, P, S
Damm [24]
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
Here are some in order without the song.
Hydrogen helium lithium beryllium boron carbon nitrogen oxygen fluorine neon sodium magnesium aluminum silicon phosphorus sulfur chlorine argon potassium calcium scandium titanium vanadium chromium manganese iron cobalt nickel gallium germanium selenium arsenic
-All most likely occur on steep slopes
-They all depend on gravity
-They all occur after heavy rain
