the answer is hydrocarbons contain 10 hydrogen atoms :D
Answer: Seastars prey on mussels and shellfish which would otherwise have no other natural predators. Herbivorous fish like the butterflyfish pictured to the left prey on marine algae. Without this crucial predator-prey balance, the algae would over-grow, which would then kill coral, as they compete for the same resources.
Answer:
0.02564 kg ore contain 10.0 g of nickel.
Explanation:
Given data:
Percentage of nickel in ore = 39.0%
Mass of ore required to have 10 g of nickel = ?
Solution:
39.0% means that 39.0 g of nickel is present in 100 g of ore thus,
39/100 = 0.39
0.39 × X = 10.0 g
X = 10.0 g/0.39
X = 25.64 g
Gram to kilogram:
25.64 g × 1kg /1000 g
0.02564 kg
Answer: Oxidation reaction occurs when a reactant losses electrons in the reaction.
Reduction reaction occurs when a reactant gains electrons in the reaction.
Explanation: Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Answer:
100% pea plants will be with green pod and with round seeds.
Explanation:
As per the question given, a homozygous pea plant having green pod (gg) and round seeds (WW) is crossed with a pea plant having homozygous green pod (gg) and heterozygous round seeds(Ww). A pea plant homozygous for green pod and round seeds (ggWW) will produce one type of gametes having alleles (gW), whereas, a pea plant homozygous for green pod and heterozygous for round seeds(ggWw) will produces two type of gametes having alleles gW and gw. On crossing, phenotypically, they will produce all pea plants with green pod and round seeds. But genotypically, 50% of green pod pea plants with homozygous round seeds and 50% of green pod pea plants with heterozygous round seeds.
