Explanation:
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
How are a good chain and a good web different
Answer:
Explanation:
A food chain only follows one path of what food animals eat. A food web consists of many food chains that show how plants and animals are connected. In conclusions, a food chain focuses on a certain animal or their path and they are linear. Food webs are more complex which show how the ecosystem works together to create a balance.
Answer:
A food chain goes in one drection and a food web is more complex and is a whole system of connected food chains.

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 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.

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
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.

Answer:
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.

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:
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.

What is the success rate of implementation of transgenic embryos in surrogate dams? A) 50% B)100% C)25% D)<12.5% E12.5%
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.

Photosynthesis takes place in the _______________ and releases __________________.
A. mitochondria, oxygen
B. chloroplast, oxygen
C. mitochondria, carbon dioxide
D. chloroplast, carbon dioxide
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.
Which product of photolysis is needed for the continuation of the light reactions?
Answer:
Here, NADP+ is the final electron acceptor, which becomes reduced to NADPH. Meanwhile, ATP is also formed. Therefore, these light reactions release oxygen as a waste product of photosynthesis, while ATP and NADPH are essential to the next step in photosynthesis, the dark reactions.
