Suppose you have made the following hypothesis:
Blizzard [7]

Answer:

Explanation:

You could look up the shark population near specific coral reefs. You could also go the simple route and say something like, "sharks eat fish so, sharks will go where the fish are and if there are fish in the coral reefs, (which there are) they would be most likely to go there".  I know this may not be the answer you were looking for but its the best I've got.

What effect does food colour have on the amount of food fish eat
Firlakuza [10]
Absolutely none. Fish take food into their mouths and taste it. If they like it, they swallow, if not they will spit it out. The color of the flakes has no bearing on what the fish takes in and tastes in my experience.
I hope this helps : )

DETERMINE THE LAUNCH ELEVATION AND MAXIMUM RANGE: The test vehicle should obtain a burnout velocity of 7200 m/s at 180 km altitu
fenix001 [56]

Answer:

Flight path angle= 15.12°, maximum range= 5.29× 10*6 km

Explanation:

u= 7200m/s, H= 180km= 180000m

Recall that

Maximum height, H= (u*2sin*2∆)/2g

180000= (7200×7200sin*2∆)/2×9.8

(18000×2×98)/7200×7200= sin*2∆

Sin∆= 0.2609

∆= 15.12°

Maximum range, R= u*2/g

(7200×7200)/9.8

= 5289795.92km

= 5.29× 10*6 km

A. Calculate the approximate number of atoms in a bacterium. Assume that the average mass of an atom in the bacterium is ten tim
ludmilkaskok [199]

Answer:

a. Approximate umber of atoms = 10¹¹

b. number of atoms = 50 atoms thick

Note: The question is missing some parts. The complete question is as follows; Calculate the approximate number of atoms in a bacterium. Assume that the average mass of an atom in the bacterium is ten times the mass of a hydrogen atom. (Hint: The mass of a hydrogen atom is on the order of 1×10⁻²⁷ kg and the mass of a bacterium is on the order of 1×10⁻¹⁵ kg)

Explanation:

a. Approximate umber of atoms = mass of bacterium / 10 * mass of hydrogen

number of atoms = 10⁻⁵/ 10 × 10⁻²⁷

number of atoms = 10¹¹ atoms

b. The cell membrane is 10-8 m thick while the hydrogen atom has a diameter of 10-10  m.

The number of atoms in the cell membrane = d1 / 2 × d2

where d1 = diameter of cell membrane; d2 = diameter of hydrogen atom

The number of atoms in the cell membrane = 10⁻ / 2 × 10⁻¹⁰ = 50 atoms
