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?
Answers
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.

Based on the living things in the pyramid, please tell me what examples would fit into these categories
Primacy Producers, primary consumers, secondary consumers, and tertiary consumers.
Answers
Answer:
Primacy Producers----- Oak tree , primary consumers------ Caterpillars , secondary consumers ------- blue jays, and tertiary consumers ----- hawk.
Explanation:
Oak tree refers to the primacy Producers in this pyramid because it produces food by using the solar energy. Caterpillars are primary consumers that feeds on the producers and also known as herbivores, blue jays are the secondary consumers that feeds on the primary consumer which is the caterpillar, and tertiary consumers are the hawk that feeds on the secondary consumer i.e. blue jays. In this way, energy flows in the food chain of an ecosystem. During this flow of energy, only 10% of energy is transferred from one trophic level to another while the remaining releases in the environment in the form of heat energy.

denitrification
Explanation:
Denitrification occurs when N is lost through the conversion of nitrate to gaseous forms of N, such as nitric oxide, nitrous oxide and dinitrogen gas. This occurs when the soil is saturated and the bacteria use nitrate as an oxygen source. De-nitrification is common in poorly drained soils.

A. mitochondria, oxygen
B. chloroplast, oxygen
C. mitochondria, carbon dioxide
D. chloroplast, carbon dioxide
Answers
Answer:
B. chloroplast, oxygen
Explanation:
This is because plants take in the carbon, water, air,and it transforms the water into oxygen and carbon into glucose. So it absorbs light, and the chloroplasts are special structures that are responsible for that absorption of light, They are green, because of chlorophyll, which gives the green pigment to leafs
photosynthesis takes place inside them, so they can absorb light to start the process.

Answer:
D. Ted should be wearing a self-contained breathing apparatus
Explanation:
According to this question, Ted has entered into an empty pit in order to do some maintenance work and his colleague, Sam, is outside the pit ready to assist him in case of emergency.
It is necessary to take additional precautions even if Ted is tied to a lifeline or the pit is empty. However, the additional precaution should be that Ted should be wearing a self-contained breathing apparatus (SCBA) in case of breathing or respiratory problems down the pit.

7. In an abandoned field, the gradual replacement of grasses by shrubs and then by trees is known as A) predation B) saprophytism C) ecological succession D) transfer of energy
Answers
Answer:
C. Ecological Succession.
Explanation:
A is incorrect because predation is the act of an animal preying on another animal for food which has nothing to do with grass and trees. B is incorrect because saprophytism is the ability of certain plants to live in dead or decaying organic matter. For example, imagine mushrooms growing on decaying trees. That still doesn't explain what the REPLACEMENT of grasses, bushes, and trees are called. D is incorrect because that is energy transferring to another, that answer wouldn't make sense. From what I know, ecological succession is the process of change in the species structure of an ecological community over time. So, if there is an abandoned field but grasses and trees are slowly popping up there over time (There's a lot more to it) then C, ecological succession is your answer.

Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?
Answers
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is C.There are not enough nucleotides available to construct new DNA.
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.

Two samples of radioactive material from the same rock is prepared for testing. Sample A is cut into a 2 inch cube. Sample B is crushed into a fine powder. Compared to the half-life of the material in Sample A, the half-life of the material in the powdered Sample B is:
Answers
Answer:
The same
Explanation:
Half life is the time taken for the number of atoms in a radioactive sample to decrease to half of the initial number of atoms. It is also the time taken for the activity of a radioactive sample to decrease to half of its original value.
If samples A and B were obtained from the same rock, then they contain the same number of atoms having the same initial activity even though the samples were not prepared in the same way for analysis.
Hence, samples A and B have the same half life.

Which of the following crosses would be expected to produce the greatest variety of genotypes among the offspring?
Answers
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.
