B.) Photosynthesis and cellular respiration are competitive processes that require the same reactants to start a reaction
C.) Photosynthesis and cellular respiration are complementary processes that could not occur without one another
D.) The only difference between photosynthesis and cellular respiration is whether or not light is available to start the reaction
Answer:
The correct answer would be C.) Photosynthesis and cellular respiration are complementary processes that could not occur without one another.
Photosynthesis is the process by which green plants convert sunlight into chemical energy or food or glucose.
It produces glucose or food from simpler substances like carbon dioxide and water in presence of sunlight and chlorophyll.
The overall reaction can be written as:
6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂
In contrast, the cellular respiration converts the chemical energy of the food into ATP (adenosine triphosphate).
It oxidizes glucose completely in presence of oxygen to produce carbon dioxide, water, and energy (approximately 36-38 ATP).
It takes place in almost all organism including plants.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
Thus, we can say that photosynthesis and cellular respiration are complementary to each other.
(B) species.
(C) genus.
(D) family.
(E) phylum
How did detectives nab the suspect based on the pod evidence?
A) Detectives knew that Palo Verde trees grew in a limited area of the state.
B) Detectives used DNA markers to match the pods from the truck to pods on the scene.
C) Detectives constructed a pedigree chart of the trees in the area to determine genotypes.
D) Detectives did test crosses in the lab to determine the relationship of the pods and trees
Detectives used DNA markers to match the pods from the truck to pods on the scene to nab the suspect in an ongoing murder investigation. Hence, the correct option is B.
DNA markers are the variations that can be used to identify and track specific genes or regions of the genome. DNA markers are used in a variety of applications including medical, genetics, forensic science and agriculture.
There are several types of DNA markers such as SNP, AFLP, microsatellites, RFLP. In forensic science, they are used to identifying individuals by analyzing the DNA samples that are collected from the scene of crime.
In the case given here, by using DNA markers, the forensic experts helped the detectives to match the pods from the truck to the pods on the scene. Hence, the correct option is B.

What’s the mRNA sequence?
What will be the amino acid sequence?
Will there likely be effects?
What kind of mutation is this?
mRNA Sequence: AUGUGGAACCGUGACU
Amino Acid Sequence: Methionine-Tryptophan-Asparagine-Arginine-Cysteine.
Likely Effects: Minimal impact, as the mutation is a silent mutation, not changing the amino acid.
Mutation Type: Point Mutation.
To find the mRNA sequence, we need to perform transcription, where DNA is used as a template to synthesize complementary mRNA. In this case, we have a substitution mutation in the DNA sequence, so the mRNA sequence will also be affected.
Original DNA Sequence: T A C A C C T T G G C G A C G A C T
Mutated DNA Sequence #5: T A C A C C T T G G G A C G A C T
The mRNA sequence is formed by replacing T with U (uracil) in the DNA sequence:
Original mRNA Sequence: A U G U G G A A C C G C U G C U G A
Now, let's determine the amino acid sequence using the mRNA sequence. Amino acids are coded by codons (three-letter sequences). Here's the mRNA sequence grouped into codons:
AUG UGG AAC CGC UGC UGA
The codons code for specific amino acids:
AUG: Methionine (start codon)
UGG: Tryptophan
AAC: Asparagine
CGC: Arginine
UGC: Cysteine
UGA: Stop codon
So, the amino acid sequence is Methionine-Tryptophan-Asparagine-Arginine-Cysteine.
As for potential effects, the mutation seems to result in a single amino acid change (from glycine to asparagine). Whether this has significant effects on the protein's function depends on its role. If the protein is critical for an essential function, even a single amino acid change can have noticeable effects. However, if it's a less crucial protein or a non-coding region, the impact may be minimal.
This mutation is a point mutation, specifically a missense mutation, where one nucleotide is substituted with another, leading to an amino acid change in the resulting protein.
