Systolic pressure is when the ventricles contract.
Answer:
Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range.
Explanation:
Answer:
Evolution
Explanation:
Evolution is the change in habits, hereditary and physical characteristics of a species over various generations in response to environmental conditions. Evolution lead to adaptation, the nature selection of the fittest and elimination of remaining.
Evolution may produce variety and diversity in response to mutation, genetic drift and other genetic variation. These changes may pass to offspring and may express them more in one group of population.
Evolution also explain the unity among organisms by explaining their shared characteristics. This refers to their common ancestors.
Answer:
None of the Above.
Explanation:
The correct answer is fitness. The Theory of Evolution defines fitness as a result of the adaptations an organism has which increase its chance of survival.
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in <u>sexual reproduction</u> will have half of the genetic information of body cells and will be genetically <u>unique</u>. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a <u>zygote</u>: the first body of a new individual.
The new individual will now have cells that are <u>diploid</u>, meaning they have two sets of chromosomes. They zygote will have to do a lot of <u>mitosis</u> allowing it to grow quickly and ensure that all of its cells are genetically unique.
