Answer: The correct answer is E.
Explanation:
The path for the ejaculation of the sperm starts in the testicles, more exactly in the seminiferous tubules, then the path continues trough the epididymis for reaching vas deferens. Finally, the path is completed by the sperm passing through the ejaculatory duct for being released by the urethra.
Therefore the correct answer is E.
Answer: True the dilution formula is a balanced of mole of the solute..
Explanation:
M1V1 = M2V2
When M1= 1.2M, M2= 0.25M V2= 1.4L and V1= ?
Then V1= 0.25*1.4/1.2
= 0.29
This indicate that 0.29L of the 1.2M NH4Cl will be dilluted to 0.25M in 1.4L of the solution....
The mole number of the solute remain constant
Answer:
The correct answer is - 3.012×10^23 molecules
Explanation:
The number of molecules is present in any mole of an element or compound are the same. To find the molecules you need to multiply the number of the moles of the compound by Avogadro's number:
Moles are calculated from the molecular weight, for AlF3
= 26.98 + 3×19
= 26.98 + 57
= 83.98
Then moles in 42 grams:
= 42/83.98
= 0.5001190 moles
Now the number of molecules = moles*Avogadro's number
= 0.500110×6.022×10^23
= 3.011×10^23 molecules
Answer: Conclusion
Explanation:
After they test the hypothesis they come to a conclusion of the answer.
and sometime test it again and again
The answer is competition. It's competition because they are protecting their territory, so their way of protecting or fighting for their territory is to urinate on their territory. By a way of showing that they don't want nobody in their territory.
