Which of the following is an advantage of sexual reproduction?
A. Produce identical copies of an organism.
B. Produce natural variation to adapt to environmental change.
C. Quickly populate a new habitat.
D. Reproduce very quickly.

Answers

Answer:

B

Explanation:

Produce natural variation to adapt to environmental change is an advantage of sexual reproduction. Correct Option is 2.

The advantage of sexual reproduction is that it produces genetic variation within a population. During sexual reproduction, offspring inherit a combination of genes from both parents, leading to unique genetic combinations. This genetic diversity results in natural variation among individuals within a population.

This variation is advantageous because it allows a population to better adapt to changing environmental conditions. In a changing environment, some individuals may possess traits that are better suited to the new conditions, making them more likely to survive and reproduce. Through natural selection, these advantageous traits can become more prevalent in the population over time, enhancing the population's overall ability to adapt and thrive.

Which two atoms form an ionic bond?

Answer : A

Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).

Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.

Thus, the correct answer is option (C).

Answers

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as: vestigial structures.

Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.

These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.

These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.

The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.

Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.

Describe the structure and bonding of gold

Answers

Answer:

structure

The arrangement of atoms in gold follows what's called a "​face centred cubic" (fcc) structure. Put simply, the atoms in gold form cubes, with an atom at each of the corners, and another atom in the centre of each of the faces (you can see what this looks like in the image below).

bonding

Silver, iron, platinum, gold, and copper all form metallic bonds. Unlike covalent bonding, metallic bonding is non-directional. The strong bond consists of positively charged metal atoms in fixed positions, surrounded by delocalized electrons.

Explanation:

Gold's atoms are face-centered cubic (fcc) and has metallic bonding in it's structure.

What is the bonding and structure of gold?

Because a cloud of electrons holds the atomic nuclei of gold together, gold is soft. Instead of having a set of electrons allocated to one nucleus, this cloud floats through the gold framework. Metallic bonds are the forces that exist between the nuclei and the electron cloud.

In gold, atoms are arranged in a configuration known as a "face-centered cubic" (fcc) structure. Simply put, the gold's atoms take the shape of cubes with one at each of their four corners and another in the middle of each of their six faces.
