Some minerals are evenly distributed around the planet, while other minerals are quite rare. Why are some minerals so rare and unevenly distributed?
A. Certain minerals form only under high heat and pressure that develop near volcanoes.
B. Certain minerals form only in Earth's crust, so they are difficult to locate.
C. Certain minerals form only in specific climates, and not all climates, are the same around the world.
D. Certain minerals form only in the extreme heat found at the bottom of lakes and rivers.
Please answer with an explanation THAT ISNT a browser answer you just copied pls
Answer:
A.
Explanation:
certain minerals form only under high heat and oressure that develop near volcano. That is why minerals vary among areas.
The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.
What are minerals?A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.
Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.

Hemostasis involves a complex chain of events, and any disorder that affects any individual clotting factor can disrupt the entire process. As a result, managing many clinical conditions involves controlling or manipulating the clotting process. Excessive coagulation can cause dangerous blood clot conditions such as the formation of an embolus and a thrombus. Inadequate coagulation is associated with disorders like hemophilia, an inherited disorder characterized by the inadequate production of clotting factors. About one person in 10,000 has hemophilia. What is the name of the formed element that is critical for initiating the formation of a blood clot
Answer:
Fibrin
Explanation:
The name of the element that is critical for initiating the formation of a blood clot is fibrin.
Fibrin is a fibrous, non-globular protein that is formed by the polymerization of fibrinogen as a result of the reaction with protease thrombin. The threads from fibrin form a network of fibers around the platelet plug at the area of damaged blood vessels in the process of injuries, thereby forming the initial clot.

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
population II stars
red dwarf stars
population I stars
brown dwarf stars
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.

Arrange the following steps to explain the process of protein synthesis inside the eukaryotic cell.
Answer:
Ribosomes are produced inside the nucleus, by the nucleus, then leave the nucleus through nuclear pores
Some ribosomes attach to ER whereas others move freely in cytoplasm
Ribosomes use mRNA to make proteins
Ribosomes synthesis proteins that are then placed in vesicles (sacs)
Proteins then move to the golgi apparatus where they get folded and carbohydrates and lipids attached to them
Fully active proteins leave the cell through cell membrane

1. How is the property of compressibility of gases used in everyday life? Give an example.
Answer:
Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.
Everyday life examples:
(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.
(2) Tubes of bicycles are filled by the pumps that compress the air.
(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.

How does the crossing-over of chromosomes that occurs during recombination result in increased genetic variability in population?
THIS IS A TEST ANSWER
Answer:
they swap alleles
Explanation:
when homologous chromosomes cross over during meiosis, they exchange segments of DNA/swap alleles. this means that the chromosomes now have a completely unique combination of alleles, which causes variation. It is also random which of these unique chromosomes end up in which daughter cell (the gametes) and since fertilisation is a random and independent event, which unique male gamete that fertilises which unique female gamete is also random. This means the resultant zygote has a unique combination of alleles that is unlike either of their parents.
Mitchell's family has the unusual trait of having an extra finger. Many members of his family were with an extra finger, which is a recessive trait. a family dinner, Mitchell's grandmother helped him sketch a pedigree of the family. Dark-shaded family members were born with an extra finger. No shading indicates people who do not have an extra finger. A question mari means it is unknown. Mitchell is #8 on the pedigree and grandmother is #2. Based on the pedigree what do you predict members number 12 number 11 and 13.

As skeletal muscle is further stretched beyond the length where optimum force is developed, ________. As skeletal muscle is further stretched beyond the length where optimum force is developed, ________. the thick filaments overlap one another, thereby reducing their ability to interact with actin the thin filaments overlap one another, thereby reducing their ability to interact with myosin the thick filaments are pulled away from one another, thereby reducing their ability to interact with actin the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin the amount of calcium released by the sarcoplasmic reticulum is reduced as length increases
Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.
