What makes one mineral harder than the other? Explain

Biology
2 answers:
Lana71 [14]3 years ago
5 0

Answer:The ones that are tightly bound together look different than do ones with looser bonds. For example, in the illustrations below, (A) shows the atomic structure of carbon in a diamond, and (B) is the carbon arrangement in graphite. (A) is more compact than (B), hence it is harder.

Explanation:Rocks are made of minerals, and different minerals have different crystal structures. The chemical bonds that hold atoms together in these minerals are stronger in some than in others, and the atoms themselves determine which bonds are stronger than others.

Answer:

The hardness of a mineral is mainly controlled by the strength of the bonding between the atoms and partly by the size of the atoms. It is a measure of the resistance of the mineral to scratching, the Mohs scale is for natural minerals.

The sister taxon of the Chordata is the _____.
snow_tiger [21]

Answer:

Ambulacraria

Explanation:

Ambulacraria or Coelomopora is an invertebrate clade that encompasses the Echinodermata and Hemichordata within the deuterostomies. This grouping is considered Chordata's sister taxon because it has a common ancestor.

The phylum Chordata is considered the last within the evolutionary range and comprises all vertebrates and some invertebrates such as amphioxus and tunicates. The main feature of this phylum is the presence of notochord in at least one of its embryonic phases. In vertebrates, the notochord will later make room for the Vertebral Column.

The evolution of H. floresiensis is an example of island dwarfism.

Explanation:

H. floresiensis is a species of hominid. It differs significantly than the other hominid species in size though, as it appears to be a dwarfed version of its ancestors and close relatives. Its alleged ancestor is literary twice taller, which brings in the question as to what has triggered such an evolutionary adaptation.

This hominid species lived only on a relatively small island, in isolation. The resources are very limited, and the climate is warm and humid all year around. As seen in many species of animals, when individuals get into such an environment, they tend to experience either island dwarfism, or island gigantism. The island dwarfism tends to be common among large and medium sized species, while the island gigantism tends to be more common among the small species.

When the ancestors of H. floresiensis ended up in this environment, it was advantageous for them to smaller. The reason for that is that smaller bodies require less nutrition, and are also producing less heat.

frosja888 [35]

Answer;

-Zygote

When sperm and ovum unite at conception, a zygote results.

Explanation;

-Conception occurs when a sperm cell from a fertile man swims up through the vagina and into the uterus of a woman and joins with the woman's egg cell (ovum) as it travels down one of the Fallopian tubes from the ovary to the uterus.

-A zygote is the union of the sperm cell and the ovum. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo.
