Genotypes are effectively codes to help sort out the various possible allele pairs of genes. In contrast, a phenotype is a physical trait that can be observed.
Which term best describes viruses?
a. Miniscule
b. Gargantuan
c. Harmless
d. Sterile
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.

Answer:
mark most brainliest have a great day
Explanation:
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?
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.

Answer:
Figure 3
Explanation:
A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:
- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.
- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.
- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.
- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.

manipulates one variable to discover its effect on
another variable, while holding all other conditions
constant is called an?
A) Experiment
C) Observation
B) Hypothesis
D) Thesis
please answer i have a 60 average in this class
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.

Which of the following pairs are inaccurate?
O chromosomes
nucleic acids
O amino acids — proteins
O lipids – enzymes
O carbohydrate — energy
Answer:
The pairs that are inaccurate are lipids - enzymes (third option)
Explanation:
Enzymes are biological catalysts whose structure is formed by proteins, and for this reason there is no relationship between lipids and enzymes.
The biological function of enzymes is to accelerate biochemical reactions, reducing activation energy. As for the lipids, they are more related to other biological substances, the hormones.
As for the other options:
The chromosomes are formed by nucleic acids, specifically DNA. Amino acids form proteins. Carbohydrates are the main source of energy for living organisms.How are photosynthesis and respiration related?
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.

What do you notice about the ligands and their receptors in these images?
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.

why is sun converted into chemical energy in the bonds of organic molecules?
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.

Explanation:
Suppose that a farmer wishes to start a you‑pick berry farm, where customers pick their own fruit from the berry bushes. In this variety of berry, the tall, thornless, and terminal flower phenotypes are produced by the s, t, and a alleles respectively. These phenotypes are recessive to the short, thorned, and axial flower phenotypes, which are produced by the S, T, and A alleles. The farmer has two berry plants. When selfed, the first plant produces tall, thorned plants with a mixture of axial and terminal flowers. The other plant produces a mixture of tall and short plants, which are all thornless and have terminal flowers. The farmer wishes to generate a pure‑breeding line of tall, thornless plants with terminal flowers, as such plants are most convenient for berry‑picking. What are the genotypes of the farmer's two original berry plants?
Answer:
The genotypes of the two original plants the farmer has are as follows:
Plant 1: ss,TT,Aa and Plant 2: Ss,tt,aa.
Explanation:
A genotype is literally the underlying makeup that will produce a result that is visible and measurable, that we know as phenotype. In this particular case, we have a farmer who wishes to establish his farm with a specific type of plant: one that is tall, thornless, and has terminal flowers because they are the best for berry-picking, and that is the business he wishes to establish.
In order to be able to obtain this type of plant, he needs to first count with a starting point, the parent plants from which he will be able to produce the line he wants to establish. But to do that he needs to first know the genetic makeup with which, when he crosses the plants, he will then obtain the phenotypical results he seeks.
The question itself tells us the types of alleles (which are, in simple terms, the holders of the genetic information), that produce the phenotypical characteristics of the plants the farmer has. So we know that there is one type of bush that is tall, thornless and has terminal flowers, and its alleles are s, t and a. The other bush has short, thorned and axial characteristics, and therefore its alleles are: S, T and A.
When the question then gives us the information about the resulting plants when the originals are selfed, and their characteristics, we are able to tell the genetic makeup, or genotype, of the original two plants the farmer has because we can combine the alleles mentioned given the characteristics (phenotypes) and thus obtain the two parent plants.
Answer:
The genotypes of the two original plants the farmer has are as follows:
Plant 1: ss,TT,Aa and Plant 2: Ss,tt,aa.

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
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.
