Use the dichotomous key below to identify the cell type.
xenn [34]

The dichotomous key is not given here, however, the correct dichotomous key is as follows:

step- 1a cell has a nucleus and organelles - go to step 2

        1b cell has no nucleus or organelles - bacterial cell

step- 2a cell has a cell wall - go to step 3

         2b cell has no cell wall - animal cell

step-  3a cell has chloroplasts - plant cell

3b cell has no chloroplasts - fungal cell

Using this dichotomous key the cell can be identified as - Fungal cell.

A dichotomous key is an essential scientific tool that is used to find out the various kinds of organisms on their observable traits. Dichotomous keys have a series of statements with two different choices in each step that will take the student or user to the correct identification.

Identification of the given cell:

1. Follow step 1.

  • If cells have a nucleus and organelles - yes then go to step 2

2. follow step 2.

  • 2a. if cell has a cell wall - yes go to step 3

3. follow step 3.

  • 3a. if cell has chloroplasts - no then fungal cell

Fungal cells have a nucleus and cell organelles enclosed with a cell wall around the plasma membrane but do not have chloroplast.

Thus, Using this dichotomous key the cell can be identified as - Fungal cell.

Gases are measured in different units. Which of the following measurements of pressure are equal? Select all that apply.
viva [34]

Explanation:

Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.

    1 atm  = 760mmHg

               = 760torr

               = 101325Pa

               = 101325Nm⁻²

 1mmHg  = 1torr

        1Pa = 1Nm⁻²

101.325 kPa  and 101,325 Pa are the same

           1000Pa = 1kPa

101,325 Pa  and 1 atm

1atm and 101.325 kPa

What is the percentage by mass of copper in copper oxide (CuO)?
Viefleur [7K]

Answer:

79.89%

Explanation:

Copper has a molar mass of 63.55

Oxygen has a molar mass of 16.00

If you add these you get 79.55

To get the mass percent of copper divide copper by the whole. 63.55/79.55*100= 79.89%
