Because insertions and deletions produce a frame-shift that modifies the interpretation of following codons, they are frequently more detrimental than substitutions that modify only one amino acid.
What is a mutation?A alteration in the DNA sequence of an organism is referred to as a mutation. Errors in the replication of DNA during the process of cell division, exposure to mutagens, or viral infections are all potential causes of mutations.
Base substitutions, deletions, and insertions are the three different kinds of DNA mutations that can occur.
Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, as a result, alters the entire amino acid sequence that follows the mutation, insertions and deletions are typically more harmful than substitutions, in which only one amino acid is changed. This is because frame-shifts change the reading of subsequent codons.

Plants and animals are multicellular organisms?
Which statement best describes the difference between them and other organisms?
(A) they have organelles in each cell perform function to keep the cell alive
(B) they are made of many specialized cells types that perform specific functions to keep the entire organism alive
(C) the cells that make them up are larger than cells that make up bacteria, yeast, or amoeba
(D) they can all use socialized cells to make their own food by capturing the suns energy, other organisms cannot do this
Answer:
B) they are made of many specialized cells types that perform specific functions to keep the entire organism alive
Explanation:
A multicellular organisms are organisms that possess many cells in its body system. As stated in this question, plants and animals fall under this multicellular category. These cells begin to specialize in function as they divide through a process called CELL DIFFERENTIATION.
In comparison with the number of cells of other organisms, which are unicellular (one cell), multicellular organisms are made of many specialized cells types that perform specific functions to keep the entire organism alive whereas in unicellular organisms, only the organelles in one cell performs the function.

why does the gummy bear grow when soaked in sugar water?
Answer:
Salt or sugar ions in water are much smaller than the gelatin molecules in the candy. ... Because of osmosis, water molecules move to an area with more solute in it to balance things. The catch is that the water is locked up in the candy and can't move. The Gummi Bear can't shrink further, so it stays about the same size.

Gummy bear grow when soaked in sugar water because of osmosis, water molecules move to an area with more solute in it to balance things.
What do you mean by osmosis?Osmosis is the movement of solute molecules from lower concentration to a higher concentration of solution through a semipermeable membrane.
During osmosis, the solvent moves from the solution that is lower in solute concentration to the solution that is higher in solute concentration.
Osmosis helps in stabilizing the internal environment of the organism by balancing the levels of water and intracellular fluids. The nutrients and minerals enter the cell by osmosis which is necessary for the survival of cells.

5. What gametes are produced by the following organisms: a. Genotype YyRr, if Y and R are on different chromosomes b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
a) YR, Yr, yR, yr
b) YR, yr
c) Yr, yR
d) YR, yr, Yr, yR
Explanation:
Before gametes are formed, during anaphase sister chromatids separate and migrate to the poles. Following the low of segregation and independent assortment, alleles from the same trait and from different traits separate independently from each other. During this separation, there might be different gene combinations according to their position in the chromosome, the occurrence of crossing over, and the destiny of each chromatid.
a. Genotype YyRr, if Y and R are on different chromosomes
Genes are located in two different chromosomes, which means that there might be four possible gametes.
YR, Yr, yR, yrb. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
Genes are located in the same chromosome, which means that there might be two possible gametes.
YRyrc. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
Genes are located in the same chromosome, which means that there might be two possible gametes.
YryRd. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
The fact that there is 50% crossing over means that these genes are not linked. There are four possible gametes

What is a type of reaction that occurs when you burn something? (combine it with oxygen)
Answer:
Combustion is the scientific word for burning. In a combustion reaction, a substance reacts with oxygen from the air. Combustion reactions happen at high temperatures, and transfer energy to the surroundings as light and heat. This is why you see flames when things burn.
Answer:
A substance combines with oxygen and releases energy in the form of heat and light.
combustion is the best type of chemical reaction.
Explanation:
When a substance combines with oxygen and energy is emitted in the form of heat and light, this process is called combustion.
There are two types of combustion.
1) Complete Combustion : It is a type of combustion in which fuel is quickly react with high amount of oxygen forming carbondioxide, water, heat and light.
2) Incomplete combustion : It is a type of combustion in which fuel is react with low amount of oxygen forming carbonmonoxide, carbon and water.
Explanation: Combustion is a reaction in which a substance (a fuel) reacts with oxygen to produce heat energy. Another name for combustion is burning. Combustion can be complete or incomplete: complete combustion takes place in the presence of unlimited supply of oxygen in which the substance is completely oxidized leaving water and carbon dioxide as by-products. Incomplete combustion occurs in the presence of limited quantity of oxygen in which the substance is not completely oxidized. The byproducts are carbon monoxide and soot.
What is true about cardiac (heart) cells compared to brain cells?
Different DNA which make different proteins
Same proteins being used to create different DNA
Same DNA being used to make different proteins
Different proteins used to create different DNA
Answer:
Same DNA being used to make different proteins
Explanation:
Cells of all living organisms contain the genetic material called DNA. One of the characteristics of multicellular cells is the ability of their cell to DIFFERENTIATE i.e. form specialized cells during division.
However, it is worthy to note that all cells possess the same DNA but some of the genes contained are expressed into proteins while others are not. This leads to why cells that contain similar DNA make different proteins and perform differently.
In this case, cardiac (heart) cells and brain cells contain the same DNA but due to the expression of some genes and repression of others, they are able to differentiate into different cells.
What type of bond is formed when two atoms share one or more pairs of valence electrons?

When sufficient heat is applied, double-stranded DNA denatures into two single-stranded molecules as the heat breaks all of the hydrogen bonds. In an experiment, molecules of single-stranded DNA from species X are separately hybridized with supoosedly homologous single-stranded DNA molecules from five species (A-E). The hybridized DNAs are then heated, and the temperature at which complete denaturation occurs is recorded. Based on the data, which species is probably most closely related to species X
Answer and Explanation:
When sufficient heat is applied, DNA unwinds, and the hydrogen bonds that grip the strands together weaken and break. The process of breakdown of double-stranded DNA into single strands is called DNA denaturing. The temperature at which double-stranded DNA is half denatured is termed as Tm (melting temperature). By the absorbance of the DNA solution, the amount of strand melting is measured at 260nm. At this wavelength, nucleic acids absorb light. When DNA strands come together, the proximity of the bases in the DNA strands reduces some absorbance. When the DNA strands separate, the absorbance rises 30% to 40%, and quenching of the absorbance disappears. This is known as hyperchromicity. By using DNA denaturation, the sequence difference between the two DNA sequences can also be detected. When double-strand DNA is heated, it denatured into a single-stranded state. The mixture is cooled to allow the strands to re-hybridize. Hybrid molecules are formed among related sequences.

The final paragraph of the CNN report said that "several eye specialists" had pointed out that the study should have accounted for heredity. Myopia is passed down from parents to children. Myopic parents are more likely to have myopic children, and may also be more likely to leave lights on habitually (since the parents have poor vision). In what way does the knowledge of this possible genetic link affect how we interpret the data from the study? Explain.
Answer:
Myopia is a phenotype that results from interactions between genetic factors and the environment
Explanation:
A quantitative trait is a polygenic trait that depends on the cumulative effects of many genes and the environment. Some examples of quantitative traits include weight and height. Myopia is a quantitative trait whose phenotype depends on the combined action of different genes and the environment. It has been shown that genetics plays a central role in this trait (myopia), it is for that reason that myopic parents are more likely to have myopic children. However, there also are environmental factors (e.g., diet) which increase the risk to suffer myopia.

You immediately step back because the spinal cord sends a command via the _______ - Word Answer Type your answer here to your leg muscles, which are acting as the ________ - Word Answer
Answer:
1. Receptor (nociceptor).
2. Afferent neurons.
3. Spinal cord.
4. Motor neurons.
5. Efferent neuron (effector).
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).
