Not Science Vocab
abnormal
unusual or not normal.
What is photosynthesis?
Photosynthesis is the process by which plants, algae, and some bacteria use light energy to convert carbon dioxide and water into glucose and oxygen.
What is the difference between abiotic and biotic factors?
abiotic=not living factors, biotic= living factors
What is mitosis and why is it important?
Mitosis is the process of cell division that produces two genetically identical daughter cells from a single parent cell. It is important for growth, repair, and the replacement of cells.
What role does similar DNA sequences play a role in supporting common ancestory?
DNA sequence similarities help establish evolutionary relationships among species. Organisms with more similar DNA sequences are likely to share a more recent common ancestor, providing evidence for common ancestry and evolutionary connections.
Circulate
To move around in a loop or path.
What is the importance of photosynthesis for all life on earth?
Photosynthesis is crucial because it provides the primary source of energy for nearly all living organisms and releases oxygen into the atmosphere, which is essential for the respiration of most life forms
What might happen if carrying capacity is exceeded?
If the carrying capacity is exceeded, resources may become depleted, leading to a decline in population size, increased competition, and potential ecosystem collapse.
How does cell differentiation occur?
Cell differentiation occurs through changes in gene expression and environmental signals that guide cells to develop into specific types with distinct functions.
Why are similarities in anatomical structure important for studying evolution?
Similarities in anatomical structures, such as bones or organs, suggest that different species may share a common ancestor. By comparing these structures, scientists can infer evolutionary relationships and the presence of homologous traits.
Quantitative
data or observations that involve numerical measurements
During cellular respiration, what is the significance of carbon dioxide and water as output?
Carbon dioxide and water are byproducts of the chemical reactions in aerobic respiration. Carbon dioxide is expelled from the body as waste, and water can be used in other cellular processes.
How do invasive species influence biodiversity?
Invasive species can negatively affect biodiversity by outcompeting native species for resources, leading to a decline in native populations and altering the ecosystem balance.
What impact do environmental factors have on trait expression?
Environmental factors can affect how genetic traits are expressed. For instance, certain environmental conditions may enhance or suppress the expression of particular traits. Statistical methods can help analyze how these factors interact with genetic influences.
How does heritable genetic variation contribute to evolution?
Heritable genetic variation introduces new traits into a population through mutations and sexual reproduction. This variation is passed on to offspring and provides the raw material for natural selection to act upon, leading to evolutionary changes.
Conserve
To use something carefully so it’s not wasted.
Why is energy flow in a food chain not perfectly efficent?
Energy flow is not perfectly efficient because some energy is lost as heat at each step in the food chain.
How do herds of animals use group behavior to protect themselves.
Herd animals use group formation to create a barrier against predators and protect vulnerable members of the group.
How does meiosis create new genetic combinations?
Meiosis creates new genetic combinations through processes like crossing over, where homologous chromosomes exchange genetic material, and independent assortment, where chromosomes are randomly distributed into gametes. This shuffling of genes leads to genetic diversity in offspring.
Why might not all offspring survive in an environment?
Not all offspring survive due to environmental constraints such as limited resources, predation, and competition. These factors create selective pressures that determine which individuals are more likely to survive and reproduce.
Constraints
limitations or restrictions that must be considered when designing solutions to problems. Including: cost, materials, time, environmental impact, and societal needs
How does the cycling of matter help maintain balance in an ecosystem?
The cycling of matter ensures that essential elements are continuously reused and available for living organisms, helping to maintain the balance of the ecosystem.
What could happen to an ecosystem if an extreme event like a volcanic eruption occured?
After an extreme event like a volcanic eruption, the original ecosystem might be destroyed, leading to the formation of a new ecosystem through primary or secondary succession.
How does the reproductive system interact with other body systems?
The reproductive system interacts with the endocrine system (through hormone regulation), the circulatory system (through blood supply), and the nervous system (through sexual behavior and arousal). These interactions ensure the proper functioning of reproductive processes.
How does natural selection lead to evolution over time?
Natural selection contributes to evolutionary change by favoring individuals with advantageous traits, leading to an increase in the frequency of these traits in the population. Over time, this process results in populations adapting to their environments and evolving in response to selective pressures.
