icang [17]

Answer:

The answer is "The First choice".

Explanation:

The whole question can be found in the file attached.

The water vapor inside the air freezes thru the entrance of its nitrogen. This is because liquid nitrogen has a very low temperature and seems to be sufficiently cold to condensed and freeze the steam of water. At air pressure, it has a boiling temperature of -196°C. Freezing the skin producing freeze or cold burns can be associated with direct contact.

A zinc block with a mass of 230 g is given 1320 J of energy. What is the change in
Mariana [72]

Answer:

14.7°C

Explanation:

Q = m·ΔT·c

ΔT = \frac{Q}{m*c}

ΔT =\frac{1320 J}{230 g* 0.39 J/gC}

     = 1320 J / ((230 g) * (.39 J/g°C)

ΔT = 14.7 °C

Fill in the blanks am giving brainliest and thanx
QveST [7]

Answer:

Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus

Explanation:

<u>Organelles</u> are membrane bound only in eukaryotic ccells.

Prokaryotic cells unlike eukaryotic cells, do <u>not have membrane bound organlles.</u>

Something that is found in <u>both prokaryotic and eukaryotic cells is the cytoplasm</u>, which is fluid that is inside the whole cell.

Unlike eukaryotic cells, <u>prokaryotic cells have loose DNA</u>, which floats around the cell quite literally.

The only way DNA is stored in eukaroyotic cells is in the <u>nucelus</u>, which is only found in eukaryotic cells, not prokaryotic.

Hope this helps ;)
