Answer:
B. From sea to land, toward areas of lower air pressure
Explanation:
The pattern of wind flow is most likely to occur from sea to land during a hot summer season in a coastal location due to difference of air pressure. In the summer season when the land is heated, the temperature of the air also increases and hot air rises up, as a result a region of low pressure is created at the surface. The air over the sea moves into this area of low pressure on the land. Hence, the direction of the wind is from the sea to the land during the day in summer season.

least amount of digestion. For each tube, explain why it would
have exhibited that that level of digestion.
2. How could the experiment be modified to further test human
digestion actions? What variables would you change? What would
you keep the same?
3. In which test tube was the activity most like that of a real human
stomach? Explain.
Answer:
Los alimentos son nuestro combustible y sus nutrientes proporcionan a las células del cuerpo la energía y las sustancias que necesitan para funcionar. Pero, antes de que los alimentos puedan hacer eso, los debemos digerir, descomponiéndolos en trozos pequeños para que nuestros cuerpos los puedan absorber y aprovechar.
El primer paso del proceso digestivo tiene lugar antes de que ni tan siquiera probemos la comida. Con solo oler una tarta de manzana casera o pensar en lo delicioso que va a saber un tomate maduro, empezamos a salivar, y el proceso digestivo se inicia preparándonos para ese primer bocado.
Casi todos los animales tienen un sistema digestivo en forma de tubo, donde los alimentos:
entran por la boca
pasan por un largo tubo
salen del cuerpo en forma de heces (caca) a través del ano
A lo largo del camino, se descomponen en moléculas diminutas para que el cuerpo pueda absorber los nutrientes que necesita:
Las proteínas se deben descomponer en aminoácidos.
Los almidones se descomponen en azúcares simples.
Las grasas se descomponen en ácidos grasos y glicerol.
Los residuos que el cuerpo no puede aprovechar son los que salen del cuerpo en forma de heces.

How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism
Answer:
if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual
Explanation:
A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?
Answer:
Due to over-pumping of water.
Explanation:
The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

What is the ultimate role of ecological succession in an environment
Answer:
The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.
Explanation:
The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.
What is Ecological Succession?This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.
The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.
This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.
The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.
Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.

Researchers Robert Briggs and Thomas King used ultraviolet radiation to destroy the nuclear DNA of frog eggs. Nuclei from adult skin cells and from tadpole-gut epithelial cells were cultured and then injected into eggs that had their nuclei destroyed. The results were tadpoles. Which conclusion is supported by the data from this investigation?
Answer:
Nuclei of gametes and somatic cells are similar to each other in its function.
Explanation:
The conclusion of the data is that the nuclei of gametes and somatic cells are similar to each other because both performs same function in the cell i.e. regulates activities of the cell. The nuclei of somatic or skin cells work efficiently in the egg cells due to similar composition and structure of nuclei that performs similar function in the cell so that's why injection of skin cell's nuclei into egg cells results the same i.e. formation of tadpoles.
How can a chloroplast, a structure found in plant cells but not in animal cells, provide energy for BOTH plants and animals?

A study has shown 75% of teenage boys drink 1 liter of soda per day. How many 250 ML cans of soda would a boy drink in a week if he drank 1L per day?
According to the study, if the boy drinks one liter of soda per day then, he will drink 28 soda cans of 250mL volume in a week (seven days). Each day, he drink four cans of 250mL.
What is Soda drink?A soft drink is a drink which usually contains water, artificial sweeteners, and a natural or artificial flavoring agent. The sweetener used in the soda drink can be a sugar, high-fructose corn syrup, fruit juice, a sugar substitute, or combination of these compounds. They may also contain caffeine, coloring, preservatives, and other ingredients.
If a boy drinks 1 liter of soda per day. Then, the number of cans of 250mL soda he drinks in a day will be:
1 liter = 1000mL
Number of cans which a boy drinks in a day = 1000mL/ 250mL
Number of cans of soda = 4
The number of cans which a boy drink in a week i.e., 7 days = Number of cans which a boy drink in a day × number of days in a week
Therefore, the number of cans which a boy drink in a week = 4 × 7
The number of cans of soda = 28
Therefore, the boy drinks 28 cans of soda in a week.

Suppose a trait is controlled by a gene that has one dominant allele (G) and one recessive allele (g).
Which of the following crosses would be expected to produce the greatest variety of genotypes among the offspring?
Answer:
Gg x Gg
Explanation:
Gg x Gg crosses would be expected to produce the greatest variety of genotypes among the offspring.
What is Punnett Square?A Punnett square is defined as a graphical representation of the possible genotypes of the offspring resulting from a particular cross or breeding event. Creating a Punnett square requires knowledge of the genetic makeup of the parents.
For a monohybrid cross, Punnett squares are 2X2 squares containing four boxes where each represents a fertilization event between the original gametes. While the second type is used to predict the outcome of breeding experiments where two traits are being observed and the Punnett square is large with sixteen boxes.
In the above example, if a Gg x Gg cross occurs, the genotype for the children will be Gg, which would be expected to produce the greatest diversity of genotypes among the offspring, i.e. 100%.
Thus, Gg x Gg crosses would be expected to produce the greatest variety of genotypes among the offspring.

A radioactive material has a half-life of 30 days. You begin with 4 grams of radioactive material.
a. How much of the original is left unchanged after 90 days?
b. After 120 days?
Give explanation. Don't go.ogle.
Answer:
a. 0.5 grams b. 0.25
Explanation:
Just use the half-life formula(I linked it below)
a. 4(1/2)^90/30=1/2
b. 4(1/2)^120/30=1/4
A. 0.5 grams is left unchanged after 90 days.
B. 0.25 grams is left unchanged after 120 days.
What is Half life?The half-life of a radioactive isotope is defined as the time it takes for half of the radioactive isotope to decay. It is stable in specific radioactive isotopes. It is unaffected by circumstances. It is also independent of the initial amount of that isotope.
It can be find out by this formula:-
[tex]N=N_o (1/2)^n\\\\[/tex]
where, N= quantity of the substance remaining
[tex]N_o[/tex]= initial quantity of the substance
n= number of half lives
For above given example,
Given that radioactive element X has a half-life 30 days
Hence the number (n) of half-lives in 90 days
n=90/30
n=3
The amount N of radioactive element X left after n=3 half-lives with initial amount [tex]N_o[/tex]=4 gm
[tex]N=N_o (1/2)^n\\\\\\N= 4 (1/2)^3\\N= 4(1/8)\\N= 0.5 gms\\\\\\[/tex]
For 120 days, n=120/30
so, n= 4
Then,
[tex]N=4(1/2)^4\\N=4(1/16)\\N=0.25 gms[/tex]
Thus, A. 0.5 grams is left unchanged after 90 days.
B. 0.25 grams is left unchanged after 120 days.

Answer:
C. a distant luminous object travels rapidly away from an observer.
Explanation:
Option C is the correct answer.
Redshift is actually observed when a distant luminous object travels rapidly away from an observer.
In redshift, observers actually see an object that is travelling away from them and it has longer wavelength. The opposite is the blueshift where observers see a light traveling towards them and shifted to shorter wavelength.
In astronomy, redshift takes place when the object's visible light travels towards the red end of the spectrum.
A red shift is observed when a luminous object is moving rapidly away from the observer.
A red shift refers to a shift to a longer wavelength. It is observed when a luminous object is moving away from an observer. This is different from a blue shift where the luminous object is moving towards the observer.
Hence, in astronomy, a red shift is observed when a luminous object is moving rapidly away from the observer.

investigating how waste production affects a certain person's ecological
footprint?
A. Opinion the person has about environmental impact
B. Measurement of the amount of waste produced
C. Identification of the person
D. Calculation of resulting ecological footprint
Answer: Measurement of the amount of waste produced.
Explanation:
Measurement of the amount of waste produced is the independent variable for a controlled experiment in this case. Therefore, the correct statement is option B.
What is the independent variable?The independent variable is the variable that can be changed in a controlled experiment. In this case, the researcher can manipulate the amount of waste produced followed by observation of its effect on the ecological footprint.
The researcher can manipulate the amount of waste by changing the factors such as the type of waste produced, recycling facilities available, etc. under controlled conditions.
Once the independent variable is manipulated, the researcher can observe its effect on the dependent variable. In this case, the ecological footprint of the individual is a dependent variable. The dependent variable is the variable that can be affected by the independent variable and is measurable.
Therefore, the measurement of the amount of waste produced is the independent variable for a controlled experiment.
