Answer:
O They are produced from molten minerals.
Explanation:
Minerals can be produce form molten rocks or materials in nature.
Minerals are solid inorganic compounds with a definite composition and an ordered atomic arrangement.
Minerals are naturally formed. When rocks melt, they can aggregate or concentrate certain minerals in parts of the melt. This process known as differentiation takes place at different temperature and pressure conditions in a molten rock.What is distillation?
Answer:
Distillation is the action of purifying a liquid by a process of heating and cooling.

Answer:
D
Explanation:
The Earth’s core has two different parts is true about the earth's layer.
What is Earths core?
The extremely hot and dense core of our planet is called the Earth's core. Underneath the chilly, brittle crust and the largely solid mantle is the ball-shaped core.
Earth was a homogeneous ball of hot rock when it first formed roughly 4.5 billion years ago. The ball heated up even more due to radioactive decay and heat left over after planetary formation (the collision, accretion, and compression of space rocks).
After roughly 500 million years, our young planet's temperature reached 1,538° Celsius (2,800° Fahrenheit), the temperature at which iron melts. The iron age refers to this crucial period in Earth's history.
Therefore, The Earth’s core has two different parts is true about the earth's layer.

what is the difference between cell membrane and visking tubing
Explanation:
cell membrane- is a semipermeable tissue that selectively allows the movement of materials in and out of a cell while a visking tubing is a artificial cee membrane
Answer:
Explanation:
Cell membrane is a semi permeable wall found in living cells . It is separate the inside cell from the the outside environment. This allow the movement of substances in and out of the cell. It allow diffusion of gases in and outside the cell.
Visking tubing is made of regenerated cellulose which look aliitle bit similar sellotape when it is dry. It is an artificial membrane that is similar to the cell membrane. It is a selectively permeable membrane with small pores that allow the movement of smaller molecules in through them.

The study of fossils is called paleontology. On earth, there are different types of fossils present on the earth. For example Body Fossils, Molecular Fossils, Trace Fossils, Carbon Fossils, Pseudofossils.
The correct answer is option A.
What are fossils?A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnantsAccording to the question, all the options are relatable to the good fossils index except option A.
The fossils can be found anywhere on the earth, not at a specific location.

Which type of mutation results in a frameshift mutation? Check all that apply.
substitution
insertion
deletion
point mutation
Which type of mutation adds one or more base pairs?
insertion
substitution
deletion
Insertion-deletion type of mutation results in a frameshift mutation changing the amino acid code for protein, hence options A and B are correct.
What is frameshift mutation?A frameshift mutation is produced via insertion and deletion. "indel" mutations, which stand for insertion or deletion mutations, result in frameshift mutations.
The way the DNA is read is altered by these changes. The nucleotides that follow in a DNA sequence can all be affected by a frameshift mutation, making them more likely to have severe effects.
A frameshift mutation is brought on by insertion and deletion, mutations from insertional or deletional mutations result in frameshift mutations.
Therefore, frameshift mutations happen when one or more nucleotides are added or removed, provided that the total number of nucleotides added or subtracted does not exceed three, disrupting the normal sequence of codons, hence options A and B are correct.
