Answer:
Igneous rock to metamorphic rock
Metamorphic rock to igneous rock
Sedimentary rock to metamorphic rock
Explanation:
In changing a rock through the listed processes heat is highly required.
Transformation from a rock to igneous rocks requires the most heat because the rock body must be molten.
Igneous rock to metamorphic rock is a metamorphic change that requires significant heat and pressure. The mineralogical fabric is affected by this change. In moving from metamorphic to igneous rock, the melting temperature of a rock must be attained in order for magma to form. Sedimentary changes to metamorphic rocks also require heat.12.

Drag the tiles to the correct boxes to complete the pairs.
Match the genetic mutations with their names.
Answer:
See below!
Explanation:
Translocation ⇒ CCGGTT + TTAGGC = CCGGTA + GTTGGC
A translocation is a change in location between two chromsomes.
Inversion ⇒ CTTAAT = TAATTC
An inversion is when a gene is flipped.
Deletion ⇒ CGAGGTT = CGTT
A deletion is when a part of gene is deleted.
Duplication ⇒ ATTCGG = ATTCGGATTCGG
A duplication is when a gene is duplicated.
Insertion ⇒ CTTAAT = CTTAACGCT
An insertion is when nucleotide bases are inserted into a gene.
Substitution ⇒ CGAT = CTAT
A substitution is when part of a gene is replaced with a different base pair.

The ion with the smallest radius is
a. Br-
b. Cl-
c. I-
d. F-
e. O2-
Answer:
D. F-
Explanation:
Br - 185pm
Cl - 175pm
I - 198pm (I'm not sure what "I" is but I guess it is iodine)
F - 147pm
[tex]O_{2}[/tex] - 152pm
=> The ion with the smallest radius is F - 147pm

what is a chemical change? and what is a physical change?
In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
A chemical change is a change where something new can be formed and normally can not be changed back. Examples of a chemical change are precipitates being formed, gases being formed, quick temperature change rust, bubbling, foaming, burning, etc. A physical change is a change where nothing new is formed and normally can be changed back. For example you painted a wooden block red. If you want, you can always change the color again. Nothing chemically or permanantly happened to it. More examples of a physical change are; color change, change of state, luster, shape, size, hardeness, etc.

what is the difference between saturated and unsaturated hydrocarbons
Answer:
Unlike saturated hydrocarbons in which all hydrogen atoms and carbon atoms are bonded together with single bonds, unsaturated hydrocarbons have double or even triple bonds between the carbon atoms.

Please help me answer Question 1.
Answer:
9 moles of oxygen are produced from 6 moles of potassium chlorate.
Explanation:
Given data:
Number of moles of KClO₃ = 6 mol
Number of moles of oxygen produced = ?
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
now we will compare the moles of KClO₃ and O₂.
KClO₃ : O₂
2 : 3
6 : 3/2×6 = 9
Thus, 9 moles of oxygen are produced from 6 moles of potassium chlorate.
19.5 g O2 is equal to how many moles of O2? _____moles O2
Explanation:
Molar mass of O2: 32g/mol
Moles of O2 = 19.5 / 32 = 0.609mol
It may be harmful when people compete to see who can hold their breath the longest underwater. Without oxygen, brain cells *
Answer: Without oxygen, brain cells cannot make enough ATP.
Explanation:
Hypoxia is a condition that occurs due to low levels of oxygen. In conditions such as holding of breath for a long period of time, the oxygen carrying haemoglobin ( oxyhaemoglobin) breaks down, releasing oxygen to the body tissues, which constantly consumes oxygen keeping the levels low.
In the presence of decreased oxygen supply, autoregulatory mechanisms that control the blood flow to the brain by adjusting the diameter of the arterioles fails. The consequent rapid decrease in the cerebral blood supply leads to hypoxia and lack of glucose( decreased ATP production). If severe hypoxia is sustained for more than a few minutes, this could lead to irreversible brain damage.
Therefore, It may be harmful when people compete to see who can hold their breath the longest underwater.
Without oxygen, brain cells die as a result of the cells being unable to
metabolize glucose.
The brain is an important organ that controls almost all the activities that
takes place in the body. They have cells which converts the glucose to
energy which is needed for day to day activities.
When there is no oxygen, glucose isn't metabolized and energy is deficient.
The brain cells won't be able to function and then causes its cells to die
thereby resulting in brain damage.

Which of the following is an example of BALANCED forces?
A ball rolling uphill
O A ball sitting motionless on the ground
O A ball bouncing on the ground
O A ball rolling downhill
Answer:
Concepts: Physical Forces
In order for an object to be balanced, then it must be in equilibrium which means that no additional forces are being exerted. A ball sitting motionless would result in a balanced force that exerts no additional forces.What kind of bonding would exist between
sulfur and hydrogen?
Answer:
nonpolar covalent
Explanation:
Comparing their electronegativities will help determine the type of bond. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The difference in electronegativity (ΔEN) is used to determine bond type. Hydrogen has an electronegativity of 2.20 and sulfur has 2.58. The difference is 0.38,so the electrons are shared in a nonpolar covalent bond.
