Describe the structure and bonding of gold
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.

what parts of a cell are most likely involved with inherited traits?
Chromosomes are most likely involved with inherited traits.
What are Chromosomes?A chromosome is defined as the long DNA molecule which contains part or all of an organism's genetic material. Most chromosomes consist of very long thin DNA fibers coated with packaging proteins where the most important of these proteins in eukaryotic cells are histones.
These structures are found in the nucleus of cells which contain long pieces of DNA. DNA is the material that holds genes and is the building block of the human body.
Chromosomes also contain proteins which help the DNA stay in the proper shape.
Thus, Chromosomes are most likely involved with inherited traits.

Answer:
eubacteria
Explanation:
I took the quiz :)
The organisms that belong to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rods, and spirals are known as Eubacteria.
What do you mean by the Prokaryotic domain?The prokaryotic domain may be characterized as the kingdom of Prokaryotes is significantly made up of two domains namely, Archaea and Bacteria. These eubacteria are classified under the domain of bacteria which is represented by the relation based on the DNA experimental approach.
According to the context of this question, there are mainly three types of eubacteria commonly found. They are round (coccus), rod-like (bacillus), comma-shaped (vibrio), or spiral. All these types of different body plans, structures, and functions with respect to their morphology.
Therefore, eubacterium is a type of organism that belongs to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rod, and spiral.

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.
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.

through plants. In your answer you should refer to materials moving upwards in a plant and to
materials moving downwards in a plant
Answer:
Explanation:
Water moves through the xylem in a stream called a transpiration stream, up to the leaves of the plant. Sugar is made during the process of photosynthesis. Unlike water and ions, it travels through the plant via the phloem, moving up and down through the plant.
What molecules are required for the Calvin cycle? (3 answers)
Answer:After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build food in the form of carbohydrate molecules. The carbohydrate molecules made will have a backbone of carbon atoms. Where does the carbon come from? The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
Explanation:The Interworkings of the Calvin Cycle
In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. The reactions are named after the scientist who discovered them, and reference the fact that the reactions function as a cycle. Others call it the Calvin-Benson cycle to include the name of another scientist involved in its discovery (Figure 5.14).
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
Answer:
CO2, ATP, and NADPH

Chlorophyll appears green because it…?
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
Answer:
A. absorbs green light
B. reflects green light
C. emits green light
ANSWER: B. reflects green light
Explanation:
our eyes can only see what objects reflect, so if it's appearing green then obviously it's reflecting the green light.

Ciliated ependymal cells: A) help form the blood-brain barrier. B) circulate cerebrospinal fluid. C) form myelin in the brain and spinal cord. D) serve as wandering phagocytes during brain injury.
Ciliated ependymal cells: circulate cerebrospinal fluid.
Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.
They are part of glial cells, which share space with neurons in the nervous system.They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.
