another variable, while holding all other conditions

D) Thesis
please answer i have a 60 average in this class
Answers
Answer:
A. Experiment
Explanation:
The question above is related to the "Scientific Method." The "Experiment" is being conducted after the researcher comes up with a hypothesis (scientific guess). This step predicts the accuracy of the hypothesis and ensures that it is being conducted "fairly." In order to do this, the researcher has to control the situation. That said, he needs to manipulate one variable at a time. All the other conditions have to remain constant.
In poultry, black is dominant to white, but the heterozygote is blue. If you consistently
eliminated the black and white birds which appear in your flock of Blue Andalusians, how many
generations of such selection would it take to produce a true breeding flock of Blue
Andalusions?
Answers
Answer:
indeterminate
Explanation:
The answer would be an indeterminate number of generations.
The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.
Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.
Which of the following allows for water molecules to have high surface
tension?
strong covalent bonds between water molecules
weak ionic bonds between water molecules
weak hydrogen bonds between water molecules
strong hydrogen bonds between water molecules
Submit
Answers
Answer:
Among common liquids, water exhibits a distinctly high surface tension due to strong hydrogen bonding between its molecules. As a result of this high surface tension, the surface of water represents a relatively “tough skin” that can withstand considerable force without breaking. A steel needle carefully placed on water will float.

How are photosynthesis and respiration related?
Answers
Function, Photosynthesis, Cellular Respiration, Significance, Considerations.
HOPE IT HELPS :)
Answer:
The products of photosynthesis are the reactants of cellular respiration; the products of cellular respiration are the reactants for photosynthesis.
Explanation:
Photosynthesis uses CO2, sunlight, and H2O to create glucose (C6H12O6) and O2. Cellular respiration uses glucose (C6H12O6) and O2 to create ATP (energy molecules), carbon dioxide, and H2O. One cannot exist without the other. They also help balance out CO2 and O2 levels in the atmosphere.
a germ line mutation can have what possible outcome on the progeny (offspring)?
Answers
Answer:
A germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ovum). Mutations in these cells are the only mutations that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote.

why is sun converted into chemical energy in the bonds of organic molecules?
Answers
Answer: The sun sustains all life on earth through photosynthesis, the process by which plants and other organisms convert the energy of sunlight into chemical energy, stored in the bonds of organic molecules. A central challenge of modern science is to replicate this process using synthetic catalysts, and thus produce solar fuels by artificial photosynthesis.

What do you notice about the ligands and their receptors in these images?
Answers
Answer:
What can be noticed about the ligands and their receptor is that the configuration of both coincide, as a key would with its lock, which demonstrates the specificity of a receptor by its ligand.
Explanation:
A ligand corresponds to a molecule considered a signal or a messenger, while the receptor is a protein on the cell surface, with the capacity to accept a ligand.
Ligands and receptors constitute pairs that complement each other, so that each receptor can bind to a specific ligand, similar to what happens with a key and a lock.
Once the ligand-receptor complex is formed, changes occur inside the cell, which define a certain effect.
Which term best describes viruses?
a. Miniscule
b. Gargantuan
c. Harmless
d. Sterile
Answers
Answer:
a. miniscule
Explanation:
A microorganism that is smaller than a bacterium that cannot grow or reproduce apart from a living cell.
Viruses are really small, much smaller than cells described as miniscule. Therefore, the correct option is A.
They are so small – ranging from 20 to 300 nanometers in size – that they can only be seen under an electron microscope. These infectious organisms are composed of genetic material, either DNA or RNA, that is coated with an inhibitory protein. Their ability to invade host cells and control the cellular replication machinery increases their pathogenicity.
Many diseases can be brought on by viruses, including the common cold, influenza, COVID-19, and more serious infections. To create vaccinations, antiviral drugs, and public health measures to prevent outbreaks and protect world health, it is essential to understand how viruses work. The complexity of these small but powerful agents is still being uncovered by ongoing research.
Therefore, the correct option is A.

Question 4 of 10
Which of these events could be a result of an error made during
transcription?
A. The next generation of the organism inherits the error
B. The mRNA produced has a different base sequence
C. A carbohydrate is produced instead of a protein
D. The gene used to produce the mRNA is altered
Answers
Answer:
B. The mRNA produced has a different base sequence
Explanation:
Transcription is the process in which mRNA is transcribed from DNA, which is then translated into a protein.
An error made during transcription does not alter the sequence of the DNA. Therefore, the gene itself is not altered and the error is not passed on to the next generation.
Carbohydrates are never produced by transcription and translation, which produce polypeptide chains which from mature proteins.

The translation is one of the important processes of the central dogma, in which the messenger RNA molecule is decoded in a ribosome.
The answer can be given as:
tRNA Anticodons - UAC Amino Acids- methionine Number of Water Molecules Produced -0In the translation, the mRNA sequence is decoded to produce the anticodons within the ribosomes. The translation of amino acids starts with the starting code AUG. The tRNA anticodon complementary to the mRNA will produce UAC.
In RNA, thymine is replaced by uracil, which is complementary to adenine. Thus, the UAC codes for methionine will be formed.

He loses consciousness.
He experiences severe shivering.
Answers
Answer:
He loses Consciousness
Explanation:
Because of his struggle to breathe he will eventually lose consciousness
An indication that a man might be choking includes the loss of consciousness. Thus, the correct option is C.
What is Choking?Choking is the inability of an organism to breathe which is caused by a blockage in the throat or windpipe. Choking occurs when an object or food particle becomes lodged in the throat or the trachea. It blocks the airflow. If the airflow is blocked in the trachea, choking can be a medical emergency and it needs urgent attention as it could lead to death.
The main symptom of choking is an inability to breathe or talk. There may be coughing. In severe cases, the skin may also turn blue. Another important indication that a man might be choking is the loss of consciousness.
Therefore, the correct option is C.
