Answer:
B. passed through levels A, B, and C to organisms
Explanation:
DDT is an insecticide that passed through the food chain from one trophic level to the next.
The concentration of DDT increases with the each trophic level in food chain and the amount of toxin increases as passes from A to B, B to C, and C to D where D has the higher concentration of DDT as it is the higher trophic level than A, B, and C.
Hence, the correct answer is "B. passed through levels A, B, and C to organisms".
Answer:
She will obtain results to support -or reject- her working hypothesis. These results are subjected to statistical analyses in order to confirm that they are statistically significant
Explanation:
The scientific method is a rigorous process that consists of raising a working hypothesis, which is tested by experimentation or observational procedures and analysis of the results. The statistical analyses may have key roles during this procedure. In an experiment that involves statistical analyses, the results are subjected to statistical measures to evaluate the significance level and thus confirm (or reject) the statements made in the working hypothesis. The p-value is one of the most used statistical measures to determine if differences are due to randomness, or they are statistically significant.
Answer:
Observation
Explanation:
The aspect of science that has to do with the recording of color, shape, and other physical features in order to identify a cell would be <u>observation.</u>
<em>Observation in science is the collection of data via perception or through the use of scientific instruments. Perception generally involves the use of human senses such as sight, touch, taste, and hearing to collect data in order to arrive at a conclusion. </em>
<u>The color, shape, and other physical features of a cell requires a perception of sight. Hence, it involves observation.</u>
The expected e heterozygous phenotype would be orange.
Codominance is a type of non-Mendelian inheritance in which both alleles of one genotype are simultaneously expressed. So, in this example if allele A is responsible for red flower color and allele a for yellow flower color, Aa genotype (both alleles) will give both colors (red and yellow mixed together give orange).
The plant would stop photosynthesis due to the lack of light in the dim closet. Chlorophyll and other colors would be lost, and it would turn white. It would eventually exhaust the energy reserves in the roots and stem and perish.
<h3>What about photosynthesis?</h3>
Photosynthesis is the process through which plants turn carbon dioxide, water, and sunlight into oxygen and sugar-based energy. More than just the essential necessities of water and sunlight are needed for growth. The five key factors that influence how well your plants or crops develop are light, carbon dioxide, water, soil organisms, and nutrients.
Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time. This mechanism primarily provides energy to the planet's life systems. This indicates that without energy, it cannot happen (from the Sun). Chlorophyll, a green pigment found in leaves, absorbs the needed light. Chloroplasts, which contain chlorophyll, are present in the palisade and spongy mesophyll cells of plants.
