Answer:
A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases.
Explanation:
A species of frog lives in a forest. A snake species moves to the ecosystem where the frogs live and begins to hunt the frogs. Using your
understanding of natural selection, what is the most likely explanation of what will happen to the frog population when the snakes, who
are predators and will hunt the frogs, move into the ecosystem?
O A. Some of the frogs would try to develop new traits to avoid the predator and pass those on traits to offspring, and the other frogs
would die.
OB. All of the frogs would try to develop new traits to be able to avoid the predator, and they will all survive and pass on their new
traits to offspring.
OC. The frogs that were born with traits that allow them to avoid the snake would be more likely to survive and reproduce, and the
frogs that are not would be less likely to survive and reproduce.
o D. Since all of the frogs have identical traits, they would all be equally good or bad at avoiding the snake and so they would all survive
and reproduce or they all would die.
Answer:
The answer is C
Explanation:
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.
When the snakes moved in, the environment changed. The frogs that have the traits to avoid the snakes will be able to adapt to this change and survive and reproduce. Those without these traits will be found by and eaten by the snakes.
Why doesn’t the chromosome number double every time a new generation is formed?
Answer:
Mitosis
Explanation:
Mitosis is the process of cell division. both daughter cells that come out of mitosis are duplicates of eachother. the chromosomes split so each cell has the same amount as the parent cell. thus, the chromosomes do not double.
To determine if a particular plant is h0m0zygous or h8t8rozygous, you would have to test cross with a (h0m0zygous, H8t8rozygous) recessive.

The measurement used for insulation is called the: H-factor R-factor X-factor L-factor
Answer:
R-factor.
Explanation:
Insulation can be defined as the process in which physical objects (materials) oppose the flow of current by providing a least resistance path or the opposition to the conduction of heat energy.
R-factor is an abbreviation for thermal resistance. The R-factor is the most commonly used measurement for providing all of the informations about the insulating properties of an insulator. Therefore, the measurement used for insulation is called the R-factor.
Most manufacturers specify the R-factor on the label of an insulating material.
Generally, the higher the R-factor of an insulating material the better it is for insulation.
Hence, the ability of a material to prevent the flow of heat or electricity (current) is largely dependent on its R-factor.

Briefly describe the layers of the atmosphere:Troposphere-Exosphere-Stratosphere-Mesosphere-Thermosphere-
Answer:
Explanation:
-Troposphere. It is the lowest layer and encompasses the Earth's surface up to an average height of 12 kilometers; about 17 kilometers in the equatorial regions and about 9 kilometers at poles
- Stratosphere.Separated from the troposphere by the tropopause is this layer containing 19 percent of the atmospheric gases, but very little amount of water vapour.
-Mesosphere. It is located above the stratosphere up to a height of 80-85 kilometers in the mid-latitudes, where the mesopause is located.
-Thermosphere. From the upper limit of the mesopause extends the thermosphere, known as the upper atmosphere.
-Exosfera. It is the last layer, the outerest until connected with the solar wind.

Answer:
Organic Molecules
Explanation:
Question 4
By examining
scientists can test predictions for situations in which it is
impossible or unethical to use experiments.
O variables
O control groups
observations
O correlation
Answer:
correlation
Explanation:
By examining correlation, scientists can test predictions for situations in which it is impossible or unethical to use experiments.
Correlation determines if there is, and measures the strength of the relationship between two variables. Hypotheses are usually tested by experiments in science, but some situations make experiments impossible or unethical to be performed directly. In such cases, simulational experiments are performed and correlation is used to theoretically determine or predict the outcome of situations.

What happens when living things get in the dirt?
Is it possible to know the location of a gene on a chromosome if only one other gene is used?
Answer:
The arm of the chromosome. Each chromosome is divided into two sections (arms) based on the location of a narrowing (constriction) called the centromere. By convention, the shorter arm is called p, and the longer arm is called q. The chromosome arm is the second part of the gene's address.

Find out two types of water purification and name and describe them here.
Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.
Why can some hazards be predicted and others can’t?
Answer:
Predicting the size, location, and timing of natural hazards is virtually impossible, but now, earth scientists are able to forecast hurricanes, floods, earthquakes, volcanic eruptions, wildfires, and landslides using fractals.
In a DNA strand, you find that 20% of the bases are Adenine. What percentage of the DNA would be Cytosine?
Answer:
Yes
Explanation:Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.

1. How does soil porosity affect water holding capacity?
Answer: Soil porosity refers to the space between soil particles, which consists of various amounts of water and air. Porosity depends on both soil texture and structure. ... Water can be held tighter in small pores than in large ones, so fine soils can hold more water than coarse soils.

Explain the relationship between codon and gene.
Answer:
A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases.
