Calculate the number of cells in a hummingbird, assuming it has a mass of 10-2 kg.
Nikitich [7]

The number of cells in a hummingbird, given the data is 10¹² cells

<h3>How to determine the mass of one cell</h3>

We'll begin by obtained the mass of a cell. This can be obtained as illustrated below:

Mass of 1 cell = 10 × mass of bacterium

But

Mass of bacterium = 10⁻¹⁵ Kg

Thus,

Mass of 1 cell = 10 × 10⁻¹⁵ Kg

Mass of 1 cell = 10⁻¹⁴ Kg

<h3>How to determine the number of cells in the hummingbird</h3>

The number of cells in the hummingbird can be obtain as follow:

  • Mass of 1 cell = 10⁻¹⁴ Kg
  • Mass of hummingbird = 10⁻² Kg
  • Number of cells =?

Number of cells = Mass of hummingbird / mass of 1 cell

Number of cells = 10⁻² / 10⁻¹⁴

Number of cells = 10¹² cells

Thus, the number of cells in the hummingbird is 10¹² cells

Explain why a hydrogen atom can become either an ion or a part of molecule?
NikAS [45]

<span>If it loses that 1 electron (0 electrons, 1 proton, 1 neutron) it become an ion that is positively charge because it has more protons than electrons. [Ignore the neutrons] </span>

<span>If it gains an electron (2 electrons, 1 proton, 1 neutron) it becomes an ion that is negatively charge because it has more electrons than protons </span>

<span>A molecule - when 2 or more "different" elements combine or when 2 or more of the "same" elements combine </span>

<span>1 proton 1 electron <----- that is considered to be neutral </span>

<span>3 protons, 3 electrons <----- neutral </span>

<span>5 protons 5 electrons <----- neutral </span>

<span>6 protons, 5 electrons <-- positive ion [more protons than electrons] </span>

<span>5 protons, 8 electrons <--- negative ion [more electrons than protons] </span>
