Answer:

(4) sperm - transports genetic material

Explanation:

Which reproductive structure is correctly paired with its function'?

(1) uterus - usual site of fertilization

(2) testis - usual location for egg development

(3) ovary - delivers nutrients to the embryo

(4) sperm - transports genetic material

Solution:

The uterus (also known as the womb) is where the fertiled egg (foetus) stays until it is ready to be delivered. The usual site of fertilization  is the fallopian tube.

The testis is responsible for the production of sperm and hormones. The uterus is where the egg development takes place.

The ovary is responsible for the production of egg and hormones. The embryo receives nutrient through the fetus.

The sperm transports genetic material to the ovum.

Answer:

4

Explanation:

because ovaries def do not deliver nutrients to the embryo thats the placenta and the testis are DEF not a site for egg development and the uterus is not where fertilization happens i believe its where the fetus is kept and therefore the only correct answer is 4 :)

Al(s) + NiSO4(aq)<br> Balance
irinina [24]

Answer:

2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni

Explanation:

This reaction type is a single replacement. The format of a single replacement is:

A+BC --> B+AC

A= Al

B= Ni

C= SO

The coefficient 3 for Ni would become a subscript for  AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

Through the complete electrolysis of a sample of pure water, a student collects 14.0 grams of hydrogen gas and 112.0 grams of ox
Vadim26 [7]

Answer:

126.0g of water were initially present

Explanation:

The electrolysis of water occurs as follows:

2H₂O(l) ⇄ 2H₂(g) + O₂(g)

<em>Where 2 moles of water produce 2 moles of hydrogen and 1 mole of oxygen.</em>

<em />

To find the mass of water we need to determine moles of oxygen and hydrogen, thus:

<em>Moles Hydrogen:</em>

14.0g H₂ ₓ (1mol / 2g H₂) = 7 moles H₂

<em>Moles Oxygen:</em>

112.0g O₂ ₓ (1mol / 32g) = 3.5 moles O₂

Based on the chemical equation, the moles of water initially present were 7 moles (That produce 7 moles H₂ and 3.5 moles O₂). The mass of 7 moles of H₂O is:

7 moles H₂O * (18g / mol) =

<h3>126.0g of water were initially present</h3>
