Rough-skinned newts produce a strong toxin called TTX as a defense mechanism against predators. Garter snakes
can tolerate a very limited amount of the toxin. However, several populations of garter snakes have recently shown
an increased tolerance for TTX. The different populations of snakes have independently acquired a gene variation
that allows them to better block the effects of the toxin.


Which of these most likely to increase in garter snakes?

A. The average number of genes in the garter snake populations

B. The number of times a garter snake replicates the variant gene

C. The frequency of the variant gene in the garter snake populations

D. The average number of times genes mutate to create a tolerance for the toxin

Explanation:

During the process of protein synthesis, the best explanation for what is occurring at the arrow is as follows:

Protein synthesis may be defined as a biological process through which cells make proteins in order to accomplish metabolic functions that facilitate the survival of living organisms. The process of protein synthesis terminates with the help of two stages. They are as follows:

Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While the process of translation acquired the transfer of genetic instructions from the mRNA to the sequence of amino acids in order to form proteins. This takes place in the cytoplasm of the cell.

Explanation:

Norther hemisphere Is the half of the Earth that lies on the north of the equator. The equator is the line that divide the Earth into two halves.

During the winter, the northern hemisphere is colder because the northern hemisphere move away from the sun and receive less sunlight form the sun. The sun is very high in temperature and it has high heat, when the northern hemisphere move away from it, there is lower heat or temperature that get to it , making it to become cooler or have lower temperature. The countries in the northern hemisphere comprises of all countries in Europe, North America, Asia,part of South America and little part of Africa.

Answer:

Helium and carbon dioxide

The elements that are not common in human body are carbon dioxide and helium. The correct options are B and E.

A chemical element is a type of atom with a specific number of protons in its nucleus, including the pure substance made up entirely of that species.

Chemical elements, unlike chemical compounds, cannot be broken down into simpler substances by any chemical reaction.

The human body is made up of only six components: oxygen, hydrogen, nitrogen, carbon, calcium, as well as phosphorus.

Sulfur, potassium, sodium, chlorine, and magnesium make up about 0.85% of the remaining mass. All 11 of these elements are necessary.

Carbon dioxide and helium are elements that are not found in the human body.

Thus, the correct options are B and E.

Answer:

Mucous membranes

Explanation:

The epidermis (external) and mucous membranes (internal) represent the first non-specific barriers that act against invading pathogens and harmful substances. The mucous membranes separate the external environment surrounding the mucous cells from the body's internal environment. These membranes are considered as selectively permeable barriers that act to prohibit the passage of pathogenic microorganisms (e.g., bacteria) and harmful agents (toxic chemical substances).

Answer:

Carbon dioxide (CO2) and water (H2O)

Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating.  Thus, option B is correct.

Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.

Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.

Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.

Therefore, selective breeding will most likely decrease genetic diversity.

Answer:

Explanation:

the number of moles of solute per liter of solution. molar concentration

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution. Explanation: To get the molarity, you divide the moles of solute by the liters of solution. Molarity=moles of solute liters of solution. For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution.

Answer:

Independent: Purposely altered

Dependent: Changes with respect to the independent being altered

Controlled: Never changes

Explanation:

An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.

A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.

A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
