The picture below shows a stained gel. The gel was made using DNA
samples obtained from individual fish. Lane 8 is the positive control for a
species of carp. Lanes 1 through 7 show DNA from individual fish. Which lane
represents a fish of the same species as the positive control (lane 8)?
Answers
In this case, Lines 5, 4 and 1 represent the same species as Line 8 in the electrophoresis gel.
What is an electrophoresis gel?An electrophoresis gel is a device used to separate molecules according to their charge and molecular weight.
Electrophoresis can be used to identify DNA samples due they may have PCR bands may have different sizes.
In conclusion, in this case, Lines 5, 4 and 1 represent the same species as Line 8 in the electrophoresis gel.

the best conclusion to make from this observation?
o O
A. Cell A produces more protein than Cell B
O
B. Cell A has a larger vacuole than Cell B.
C. Cell B does less work than Cell A.
O
D. Cell B creates more energy than Cell A.
Answers
Answer:
The best explanation regarding the observation of more mitochondria in cell A than in cell B is that cell B does less work than Cell A.
Explanation:
Mitochondria are the organelles in charge of energy production in the cell. Tissues with high energy demand, such as striated muscle, have cells with a large amount of mitochondria, to satisfy this requirement.
According to the observation, if the cell B has less work than the A cell, its energetic demand is lower and the consequence is a smaller quantity of mitochondria in its cytoplasm.
The other options are not correct because:
A and B. The fact that the A cell has more mitochondria is not related to protein synthesis or having larger vacuoles.
D. Cell B does not produce more energy than Cell B because it has fewer mitochondria.

Orchids are a recently evolved plant that have a novel feature known as aerial roots. What is the most likely function of an orchid's specialized roots? Aerial roots are the site of energy synthesis. Aerial roots allow the orchid to attach itself to trees. Aerial roots produce food for the orchid through photosynthesis. Aerial roots anchor the orchid to the ground.
Answers
Answer:
Aerial roots allow the orchid to attach itself to trees
Explanation:
Orchids are a group of plants that are mostly epiphytic in nature i.e. depends on other plants for physical supports. According to this question, orchids have evolved to develop a novel feature called AERIAL ROOTS.
This specialized kind of roots serves different functions in the orchid plants but however, the most likely is for PHYSICAL SUPPORT. The orchids use their developed aerial roots to climb and attach itself to their tree host in order for them to reach sunlight.
Answer:
the answer is B- Aerial roots allow the orchid to attach itself to trees.

Respiration is a series of enzyme-catalyzed reactions. Looking at the data below what is the optimum temperature
for the enzymes responsible for respiration?
Answers
Answer:
30C
Explanation:
One sign that a chemical reaction has taken place is the production of a gas. The more gas bubbles produced, the more reactions that the enzyme is catalyzing.
The highest number of gas bubbles are produced at 30C. The enzymes have the greatest activity in catalyzing chemical reactions at this temperature.
Therefore, this is the optimum temperature for the enzymes in this experiment.

Answers
Answer:
A mutation that changes the first letter to 'C' is called Frameshift mutation.
Explanation:
FRAMESHIFT MUTATION -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three. A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.Hence, the answer is Frameshift Mutation.C) Explain the difference in how the plant and the woman get glucose molecules to use for energy
Answers
Answer:
Ok:
Explanation:
The woman eats and digests food to get glucose while the plant can undergo photosynthesis which forms glucose.
The plant and the woman utilize different mechanisms for accumulating glucose in their body to use for energy.
What is Glucose?Glucose may be defined as the main type of sugar in the blood which provides immediate energy to the body's tissues to perform metabolic activities.
Plants utilize the process of photosynthesis to construct their food
(glucose) with the help of carbon dioxide and water in the presence of sunlight, while the woman eats food products which are then digested into the stomach, and glucose is synthesized which is then transported into the bloodstream.
Therefore, it is well described above.
