Answer:
C.22 grams because mass cannot be created or destroyed
Explanation:
Reaction equation:
2H₂ + O₂ → 2 H₂O
Mass of oxygen = 18g
Mass of hydrogen = 4g
The mass of water produced is 22g according to law of conservation of mass.
The law states that " in a chemical reaction, mass is always conserved"
The sum of the mass of product and reactants must always be the same.
Deletion is when a part of the chromosome is deleted. (Removed)
Insertion is when part of our chromosome has an extra bit added to it.
Translocation Is when one part of the chromosome is moved to another chromosome.
The correct answer is inversion, to invert means to turn upside down. So when part of the chromosome is taken off but attached backwards (turned upside down) we call it inversion
Hope that makes sense
<span>1) Which of
the following is a possible formula unit? PbO - Li2B - Al2Pb3
- ClO
The correct answer is PbO which is Lead(II) oxide – also known as Lead Monoxide
– which is an inorganic compound. It is an Amphoteric oxide which can be found,
in modern use, in industrial glass, ceramics, or computer components, due to
its crystal structure. </span>

<span>2) What is
the formula of a compound formed between iodine (I) and calcium (Ca)?
Calcium will always give two electrons. but iodine can receive only one. Therefore
two atoms of iodine react with one atom of calcium to give CaI2. Their bond is
an ionic bond.
Ca 2+ + 2I 1- --> CaI2</span>

<span>3) What is
the resulting formula unit when strontium (Sr) and phosphorus (P) bond?
Strontium (Sr) wants to lose two (2) electrons, and phosphorus (P) wants to
gain three (3). By using the criss-cross method, if you flip the 2 and 3 to the
opposite elements, you will end up with the formula Sr3P2.</span>
Answer:
If the parent reproduces sexually, it's offspring will inherit exactly half of it's DNA. The other half is inherited from the other parent. If the parent reproduces asexually, it's offspring will be a clone (i.e. have the same DNA).
Explanation:
Answer:
Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier.
