Answer: I highly suggest that you reword this but here it is...
Plants are beneficial to the lives of many species on Earth. They provide us with oxygen, while also reducing the amount of carbon dioxide in the atmosphere.
Plant go through a process called "photosynthesis." This process allows them to take in carbon dioxide, water, and sunlight, and omit oxygen and glucose. Without plants, this process would only occur in microorganisms. By themselves, microorganisms do not have enough numbers and power to be able to provide enough oxygen for the rest of the species on the planet. All species that rely on oxygen would eventually perish.
Plants also prevent erosion. With their roots, plants hold down soil and stop the soil from moving. They provide structure and strength to the loose soil. If plants were not there to hold down soil, it would be entirely up to humans to provide structure in the soil.
Finally, plants are important to us because they provide us with a food source. Humans use plants as a major source of energy. We eat plants, and mass produce them to feed ourselves. Plants are also a major food source for other animals that we rely for food. Animals that we eat get there energy from plants. If we wiped out the complete bottom part of the food chain, none of the other animals would survive.
Overall, plants are beneficial to us in many ways. They provide us with energy, stop erosion, and give us oxygen. Without plants, it would be impossible for humans to survive, and we would eventually perish.
Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
Answer;
an orange that has a prolonged shelf life
Explanation;
-Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism.
-Examples of genetically engineered (transgenic) organisms currently on the market include plants with resistance to some insects, plants that can tolerate herbicides, and crops with modified oil content.
-Genetic engineering works by physically removing a gene from one organism and inserting it into another, giving it the ability to express the trait encoded by that gene. It is like taking a single recipe out of a cookbook and placing it into another cookbook.
uracil
Explanation:
because the rest are part of the DNA strand
selection favors organisms which are well adapted to the environment.
(according to Darwin's theory)
