A strawberry farmer finds that, after a hard freeze, some of his strawberries are still alive. Which best explains why these strawberries were able to survive? A. They have larger leaves to protect the fruit than the other strawberries. B. They have different genetic variations that cause them to be more resistant to cold temperatures. C. They are able to reproduce more quickly than the other strawberries. D. The color of the strawberries is darker, and they maintain their temperature better than other strawberries.

farmers can plant the strawberries earlier in the spring and later in the fall when normal strawberries usually die. So, as a result, farmers can grow many more strawberries than they used to. So that's another benefit— plants that grow better.Finally, a third benefit is that many genetically modified plants stay fresh longer after they are harvested. So, for example, there is a kind of tomato that stays fresh in the store for about two months, instead of one or two weeks. This means that there is more time to get the food to the stores and that stores have more time to sell the food.  Less food is thrown away and wasted. So it's a great benefit to have food that stays fresh longer—and we can consume more of the food we grow.Now that we've looked at some of the benefits of genetically modified plants, let's talk about the risks of growing this type of food. We don't really know what the harmful effects are, but there are several things that people are worried about.One risk is that the genetically modified plants may start to dominate the other wild plants in the environment. This is a problem with some types of tomatoes, for example. The new tomato plants are stronger than normal plants, and because they are stronger and grow faster than the wild plants, the genetically modified tomatoes may start to dominate the environment, causing the wild plants to die. So having one plant dominate all the other plants isn't good for the environment.Another risk is that genetically modified plants will hurt wild animals and insects in the environment. For example, the genetically modified corn I mentioned earlier has already caused this problem. Now some butterflies that live near the corn are dying—butterflies that are good insects, and don't eat the corn. It's possible that corn is killing the butterflies somehow, but we're not sure. We just know that more butterflies are dying than normal. But clearly, there's a risk that genetically modified foods can hurt animals and insects in the environment.But probably the most important risk is that genetically modified food may be harmful to the people who consume the food. The alterations in the plants may cause serious problems for people—we just don't know. Scientists are trying all kinds of new things, such as putting the genes from animals into a plant. For example, to make a fruit like strawberries stay fresh longer, scientists took a gene from fish —a gene that helps the fish live in cold water—and put that into a strawberry. Will that strawberry be harmful to people? We don't know. But it may be.So it's clear that there are some important benefits to genetically modified food but also some risks—risks that a lot of people aren't willing to take.

Blackberry bushes require warm temperatures to sprout shoots and begin growing foliage.  After a period of warm temperatures, most blackberry bushes require a period of cool temperatures for proper formation of the fruit and seed.  However, several types of blackberry bushes are more tolerant of variable temperatures and can develop seeds and fruit in warmer temperatures.  If global warming becomes a permanent trend, which scenario is most likely to occur?Group of answer choicesblackberry bushes that are tolerant of warm weather will become more numerous.the blackberry bushes will evolve to no longer produce fruit.cold weather blackberry bushes will become extinct.all species of blackberry bushes will adapt and evolve into warm weather bushes.

An unexpected cold snap hits the environment in which the deer live. Suddenly, both populations need to survive in a cold climate with frequent snowfall.Explain which population of deer is more likely to survive in their new environment.

Consider data Set 1. In this data set, the soluble solid content of an advance selection of strawberry was investigated.  Six plants of this selection were randomly selected and soluble solid content was determined using a refractometer.  Test the hypothesis is the average soluble solid content of this selection was higher than 12.
