Mutations can be classified by their effect on the DNA sequence or the resulting protein. The triplet nature of the genetic code means that base changes within coding sequences can have several different outcomes.
Which of these correctly describes the effects of the different types of mutations.
Choose three that apply.
Responses
A missense mutation results from the substitution of one base, changing an amino acid to another amino acid, possibly affecting protein function. The effects of this mutation can be positive, negative, or neutral.
B frameshift mutation results from the deletion or insertion of a base or bases, resulting in a change to the amino acid sequence following the mutation. The results of this type of mutation often depend on the location in the sequence where it occurs.
C nonsense mutation changes an amino acid to a STOP codon, resulting in a change to the sequence the amino acid chain.
D frameshift mutation results from the deletion or insertion of a base or bases, resulting in a change to the amino acid sequence following the mutation. These mutations are always lethal.
E silent mutation involves a substitution of one base, but does not change the amino acid, resulting in the same protein. The results of this mutation is most likely neutral.

are less dangerous than ultraviolet rays
have very long wavelengths
are not emitted by the sun
Answers
Answer:
have very long wavelengths
Explanation:
The first X-ray image was captured by Wilhelm Conrad Roentgen (1895), who accidentally discovered these rays while experimenting with vacuum tubes. X-rays are high-energy electromagnetic radiation with very long wavelengths (in the range of 0.01 to 10 nanometers, nm). They are shorter in wavelength than ultraviolet rays and longer than gamma rays. X-rays have energies ranging from 100 electron-volts (eVs) to 100 kiloelectron-volts (keVs). On the other hand, the radio waves are blocked by the planet's ionosphere and, therefore, they cannot reach the Earth.

What are the unique characteristics of the garden pea that allowed George Mendel (the father of genetics) to study them successfully?
Answers
Mendel chose the pea, one of many species, to study because the plants and seeds exhibit a variety of distinctive characteristics that appear in two readily recognizable forms (e.g., seed shape is round or wrinkled; plant height is tall or short).
George Mendel, the father of genetics, chose pea plants for his genetic experiments for a variety of reasons, including
• Garden plants are simple to grow.
• Pea plant blooms are hermaphrodites, which means they exhibit traits of both sexes.
• Plants of the pure breed can be easily obtained through self-fertilization.
• Pea plants produce more quickly than other plants.
• They have a high rate of survival and remarkable disease resistance.
Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the idea that genes are passed down from each parent as unique, paired units.
Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the offspring. Gregor Mendel experimented with hybridization on about 29,000 pea plants. Mendel found that peas were the perfect subject since they possessed seven easily observable features that he could control. He set up two settings before starting his pea studies.
As a result, we can infer that Mendel chose the pea as the species to study out of all the others since it has a diversity of distinguishing traits in both its plants and seeds.

What are some components that makeup lipid envelopes on viruses?
Answers
Answer:
Some of the components that make up lipid envelopes on viruses include:
Phospholipids: The main component of the lipid bilayer in the viral envelope is phospholipids, which are made up of a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail.Proteins: Viral envelope proteins are embedded in the lipid bilayer and help the virus to interact with host cells, infect them, and evade the immune system.Glycoproteins: Some viruses have glycoproteins on their envelope allowing them to bind to specific receptors on host cells and initiate infection.Cholesterol: Some viruses incorporate cholesterol into their envelope to help stabilize the lipid bilayer.Lipid rafts: These are specialized regions within the lipid bilayer containing high concentrations of cholesterol and glycolipids. Lipid rafts facilitate viral entry into host cells by concentrating viral envelope proteins in a specific region.Other lipids: Viral envelopes may also contain other lipids, such as sphingolipids and gangliosides, which influence the interaction between the virus and host cells.The composition of viral envelopes can vary depending on the type of virus. These components determine the virus ability to infect host cells, evade the immune system, and replicate within the host.

Your friend says that a certain amount of kinetic energy is required to break the bonds between atoms and
make a chemical reaction go. If the molecules DO NOT have at least that energy then there will be no reaction
within the substance at all. Is your friend correct? Why or why not? If not rephrase their statement to make it
true.
Answers
The statement that a certain amount of kinetic energy is required to break the bonds between atoms and make a chemical reaction go is not entirely accurate.
The rephrased statement is:
For a chemical reaction to occur, a minimum amount of energy, called the activation energy, is required to break the bonds between atoms in the reactant molecules, and the likelihood of a reaction occurring increases with the number of molecules with sufficient energy to overcome the activation barrier."
What are chemical bonds?A chemical bond is a strong attraction between atoms or ions that allows molecules and crystals to form. Ionic bonds and covalent bonds both form when two oppositely charged ions interact electrostatically.
For a chemical reaction to occur, a minimum amount of energy, called activation energy, is required to break the bonds between atoms in the reactant molecules. This activation energy can come from a variety of sources, including heat, light, or catalysts, and it is often provided by the thermal energy of the surroundings.
However, it is not true that if the molecules do not have at least that energy, then there will be no reaction within the substance at all. In reality, there will always be some molecules with enough energy to undergo a reaction, even at lower temperatures, due to the statistical distribution of kinetic energies among molecules.

2. In Experiment 2, does adding an acid to a basic solution result in an acid or a base?
3. In which experiment is the acid added to a buffered base? How can you tell?
Answers
Acid and base are mixed to give salt and water. This process is exothermic in nature giving out heat called heat of neutralization which causes an increase in temperature.
So, these reactions can be explosive in nature when acid is added to any base and this raises the temperature of acid-base reactions.

"pH" is the negative of the logarithm of the hydrogen ion concentration, according to the simple Arrhenius definition of acids and bases. As a result, as the concentration of acid (hydrogen ions) increases, so does the pH value.
"Equal" acid-base ratios in solution require a more precise description. Varied concentrations in pure volumetric ratios can have extremely different equilibrium pH values.
If we interpret it as the common "equivalence point" where the acid and base components "neutralize," the resulting pH is in the "middle" - pH 7.0 - only when the acid and base are of equal relative strength in terms of dissociation, not concentration.
A strong base weak acid will have an equivalency point that is somewhat higher in pH than a weak base, strong acid.

how are the inheritance of yellow pod color in peas and cytic fibrosis in humans similar to each oter
Answers
Recessive traits are coded by two copies of recessive alleles. The inheritance pattern is autosomal recessive. Yellow pod color and cystic fibrosis are inherited by autosomal recessive genes.
What are recessive traits?Recessive traits are those coded by recessive alleles and can only be expressed in individuals whose genotyope is homozygous recessive. This is, individuals who only carry recessive alleles for that trait.
Alleles (dominant and recessive) are variants of the same gene.
The gene codes for a characteristic, and the allele codes for one variant of the characteristic, which is the trait.
So recessive traits are coded by the recessive variant of a gene.
Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.
For instance,
The characteristis pod color is coded by a diallelic gene. The dominant allele codes for green and the recessive allele codes for yellow. Yellow is the recessive trait.The characteristic cystic fibrosis is coded by a diallelic gene. The dominant allele codes for normal individuals, while the recessive allele codes for affected individuals. Cystic fibrosis is the recessive trait.Yellow pod color and cystic fibrosis are inherited by autosomal recessive genes.
