Answer:

Wolves are pack animals. They live together in small groups, or families.It's a howl of support, to let the pups know that the pack is there. The other pack members tip their heads back and add their voices to the call.

<h3><u>Answer;</u></h3>

C) primary cell wall → plasma membrane → cytoplasm → vacuole

<h3><u>Explanation;</u></h3>
  • The cell wall is the protective outer layer of a plant cell, that gives the cell strength and structure, and also filters molecules that pass in and out of the cell.
  • Cell membrane acts as a semi-permeable barrier separating the inside of the cell from the outside of the cell. The membrane allows regulation of what enters/exits the cell and how quickly.
  • Cytoplasm is the jelly-like fluid that fills a cell. It is responsible for giving a cell its shape and also helps to fill out the cell and keeps organelles in their place.
  • Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. They functional in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
  • <u>Potassium ion from the extracellular environment will move to the cell vacuole via the cell wall, the cell membrane and then via the cytoplasm to the vacuole.</u>

A chemist needs to know the concentration of some NaOH that is in the laboratory. To find this out, she titrates a 50.0 mL sampl
RoseWind [281]

Answer: 2.4 M

Explanation:

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

M_1 = molarity of Hl solution = 3.5 M

V_1 = volume of HCl solution = 34.3 ml

M_2 = molarity of NaOH solution = ?

V_2 = volume of NaOH solution = 50 ml

n_1 = valency of HCl = 1

n_2 = valency of NaOH = 1

1\times 3.5M\times 34.3=1\times M_2\times 50

M_2=2.4

Therefore, the concentration of NaOH solution is 2.4 M.

Acetone can be easily converted to isopropyl alcohol by addition of hydrogen to the carbon–oxygen double bond. calculate the ent
Vanyuwa [196]
<span>Answer: Enthalpy is delta-H- We need to look at the molecule and determine which bonds are broken adn which bonds are formed. Bonds that are broken are H-H (from the H2 molecule) and the C=O from acetone. their energies add up like this: 436 kJ + 745 kJ = 1181 kJ looking at the bonds formed, these are C-O, O-H, and C-H. these add up to 1229 kJ solving for delta H by taking the sum of the broken bonds and subtracting the sum of the formed bonds, like so: 1181 - 1229 = -48 kJ</span>
