Which type of species would be the perfect option to repopulate an area that is in the primary succession stages?

1 answer:

4 0

Answer:In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

How dose an atom change if all of its electrons are removed

cluponka [151]

Answer:

The atom becomes a positively charged ion.

Explanation:

The building blocks of an atom are protons, neutrons, and electrons.
The protons and neutrons present in the core of the atom are called nucleus.
The electrons are scattered in an ordered way around the nucleus.
The protons are positively charged and the electrons are negatively charged particles. The neutrons do not possess any charges.
Binding energy is supplied to the atom to remove an electron.
It is possible to remove the electrons of the lighter elements.
When an electron is removed from the hydrogen atom. It becomes positively charged ion or simply proton.
When all of the electrons are removed from the helium atom, it becomes a positively charged α particle.
It is practically very difficult to remove all of the electrons from the heavier elements.
When all of the electrons are removed from an atom it becomes an unstable positively charged ion.

Question 27 (Mandatory) (11 points)

Lostsunrise [7]

Groups

Same number of valence electrons

Li, Na, K

Explanation:

If the periodic table is not color coded, the groups of elements gives the arrangement of atoms with the same chemical properties.

All elements that are in the same group have the same chemical properties.

Periodic table groups are also called family. They are the vertical columns on the periodic table.

Elements that same number of electrons in outermost shell have the same chemical properties.

The outermost shell is called the valence shell of an atom.

They are the shell containing the most loosely held electrons. Group 1 has just one electron in their outermost shell.

Li Na k group 1

F Cl Br group 7

Why do opaque materials become warmer when light shines on them?

gavmur [86]

Opaque materials absorb all the light that shines on them. None of it comes out the other side. That's why they're opaque.

Opaque materials become warmer when light shines on them, because <em>they absorb the energy</em> carried by the light that shines on them. (According to the law of Conservation of Energy, that energy has gotta go somewhere.)
