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.

What mass is in 5 moles of helium?
ArbitrLikvidat [17]

Answer:

Mass = 20 g

Explanation:

Given data:

Number of moles of He = 5 mol

Mass of He = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass = 4 g/mol

by putting values,

5 mol = Mass / 4 g/mol

Mass = 5 mol × 4 g/mol

Mass = 20 g

What is the name given to an ion that has lost electrons? someone help me please D:
marin [14]

The name given to an ion that has lost electrons is cation. Details about cations can be found below.

<h3>What is a cation?</h3>

A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.

Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.

A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.

Therefore, it can be said that the name given to an ion that has lost electrons is cation.
