Answer:
Explanation:
Reactants
Solid 'iron'III'oxide' = Fe₂O₃
'carbon'monoxide'gas' = CO
Product
'iron'metal' = Fe
carbon'dioxide'gas = CO₂
Now
Fe₂O₃
+ 3CO
→ 2Fe + 3CO₂
The reactants are positioned at the left hand side of the equation.
The products are at the right hand side
s = solids
g = gases
This property of water affects life on Earth because it<span> floats on the surface, sustaining life at the bottom of lakes and oceans</span>
Answer:
B. An idea supported by evidence.
The display communicates that the males are from their own species and that they may not be from the same species group as the females.
Answer:
a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.
Explanation:
Tay-Sachs, which is a recessive lethal disease ---- Let say the recessive lethal diseases is s
∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.
Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.
Let show an illustration for the above statement.
Let the heterozygous individual be Ts, if Ts cross with another Ts;
we will have:
Ts × Ts
T s
T TT Ts
s Ts ss
the offspring are TT,Ts,Ts,ss
We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
