The answers that apply are;

  1. reproduction of the organism
  2. growth of the organism
  3. repair of damaged or dead cells
  4. reproduction of new cells

In the reproduction of the organism, mitosis is required in the generation of daughter cells in sexual reproduction.

In the growth of an organism, mitosis is key in the process of a cell replicating its genetic material and itself.

When a cell has been damaged, it is eliminated through apoptosis and digestion after which new cells divide by mitosis to replace the damaged cell.

Mitosis is also required in the reproduction of new cells from existing ones.

Summary of climate change
GuDViN [60]
It’s the release of harmful gases e.g. carbon dioxide into the environment due to human activity, therefore causing a rise in global temperatures, which is climate change. Warmer temperatures negatively impact our environment because it causes a decrease in biodiversity, allows more diseases to spread(most live in warmer temp.) and so on.

Sandra drew an isosceles triangle that has an angle that measures 46 degrees. Which could be the measures of the other two angle
kipiarov [429]

Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

or

46, 67 and 67°

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.
