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.

Answers
Answer:
the substance that they are missing is called chlorophyll, which all green leaves have
Substance missing from the unhealthy leaves are Chlorophyll.
Due to absence of chlorophyll the leaves do not absorb sun energy for photosynthesis. This leads to the leaves of plants turning yellow which eventually lead to the degradation of plantsWhat is chlorophyll?Chlorophyll is a pigment in the plants that provide them green color and help them to absorb energy from the sun and undergo the process of photosynthesis.

What is the success rate of implementation of transgenic embryos in surrogate dams? A) 50% B)100% C)25% D)<12.5% E12.5%
Answers
Answer:
D)<12.5%
Explanation:
Transgenic means one or more than one DNA sequences are introduced from another species by an artificial means into a surrogate dams to form a new offspring. Animals are usually make transgenic by a small sequence of the foreign DNA which is injected to the developing embryo of the surrogate mother.
The success rate for such implementation is nearly less than 12.5%, where most of the trial do not survive the injection. The surrogate mother cannot developed in most cases the implementation of one or more species into another.

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.

What kind of isolation occurs when two populations of birds have different courtship dances?
Answers
Answer: Also known as ethological isolation, behavioral isolation occurs when two populations are capable of interbreeding but don't because of differences in their courtship rituals.
average clutch Size: Two eggs
Predators: Humans, owls, and birds of prey
Main Prey Species: Small fish such as sardines ...
Species: Six
Explanation:
Behavioral isolation occurs when two populations of birds have different courtship dances.
What is Behavioral isolation ?Behavioral isolation is defined as when a species becomes reproductively isolated from others due to differences in behavior. It is one way in which nature prevents the inbreeding of species through behavioral differences.
This occurs when populations of the same species begin to develop distinct behaviors that are not recognized or preferred by members in another population. An example of behavioral difference is the mating call when two populations of the same species may have slightly different mating calls.
Thus, Behavioral isolation occurs when two populations of birds have different courtship dances.
