Answer:
The complete question includes a chart which I'm including below:
Which mutants are in the same complementation group as mutant strain 1?
of course: ("+" indicates that complementation was observed)
,,,and the answer regarding which mutants are in the same complementation group as mutan strain 1 are: 2,4, & 7.
b. They absorb dissolved carbohydrates via water.
c. They make carbohydrates through the process of photosynthesis.
d. They make carbohydrates through the process of cellular respiration.
Answer:
Out of the 22 amino acids, 8 cannot be produced in the body and must be consumed from outside sources, so they're called "essential".
Answer:
red-hot iron bar
Explanation:
An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.
The woman with ptosis and her father have the genotype Pp, while her mother has pp. If she marries a man with normal eyelids (pp), there is a 50% chance that their children will inherit the dominant P allele and have ptosis.
The subject here is centered around genetics, specifically, a dominant genetic disorder called ptosis. The woman with ptosis would have a genotype of Pp, because she inherited one ptosis allele (P, for dominant) from her father and one normal allele (p, for recessive) from her mother. Hence, her father's genotype was also Pp, and her mother's was pp.
If the woman marries a man with normal eyelids (genotype pp), each child would have a 0.5 (or 50%) probability of inheriting the dominant P allele from the mother and thus, having ptosis. This is because each child will get a p allele from the father (since he can provide only that), and either a P or p allele from the mother with the probabilities being 50% for each. Hence, for these offspring, their potential genotypes can be Pp (ptosis) or pp (normal).

B. start a chemical reaction
C. produce a catalyst
D. produce the reactants
Option B is correct.
B. start a chemical reaction
Activation energy is the amount of energy that is needed to start a chemical reaction. To start a chemical reaction we have to provide this amount of energy. Different type of catalyst are used to lower the activation energy and catalyze the reaction.
Activation energy refers to the energy needed to initiate a chemical reaction, making 'B. start a chemical reaction', the correct answer to the question.
Activation energy is the amount of energy required to start a chemical reaction. It's the necessary energy to break the initial bonds of the reactants in a chemical reaction. Without adequate energy to pass this threshold, the reaction cannot proceed. For example, the energy required to start a fire (the reaction) is the heat from a match or lighter (activation energy). Once this energy threshold is surpassed, the reaction continues until the reactants are used up or another factor stops it. Hence, the correct answer to your question is B: start a chemical reaction.
