Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.

Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support
Otrada [13]

Answer:

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. ... Sulfur is not usually mentioned as a dietary supplement because the body gets plenty of it in proteins. Humans get nitrogen from food. The element is an important component of amino acids, which are used to build peptides and proteins. Nitrogen is also an essential component of the nucleic acids DNA and RNA and all of the other molecules derived from the nitrogenous bases.

This type of energy is thought of as motion. What type of energy is present?<br> 1 point
MatroZZZ [7]

kinetic energy

The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.

What is the importance of regulating gene expression
Sonja [21]

Answer:

Regulated gene expression is crucial to the proper growth & survival of an organism and cannot be over-emphasized. Without it, the genetic code of a chromosome is the equivalent of a computer data file without the appropriate application to run it.

¿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.
