- Nearpod-12.17.20 Rea Signed in as: Aiden Hun Q Review / v Finish Tes ABC Question 3 A scientist claims that orchid populations will be smaller in areas that have an average spring temperature of 9°C compared to areas that have an average spring temperature of 7°C. Which argument BEST supports this claim? Orchid populations will be smaller at higher temperatures because the probability of male pollinating bees arriving before orchid flowering is lower. This will result in decreased orchid reproduction and smaller populations. A re Orchid populations will be smaller at higher temperatures because the probability of male pollinating bees arriving before orchid flowering is lower. This will result in increased orchid reproduction and smaller populations. Orchid populations will be smaller at higher temperatures because the probability of male pollinating bees arriving before orchid flowering is greater This will result in increased orchid reproduction and smaller populations.

- Question: In biotic feeding system, energy transfer is 100% efficient. True or False?1.1 Microbes in the soil could be beneficial to plants and one way to evaluate this is by determining the R/S ratio. Define the R/S ratio. 1.2 Both rhizospheric and root-free soils were collected from five (5) plants before (BT) and after (AT) treatment. Using the microbial biomass that appear in Table 1, the R/S ratios before (BT) and after (AT) can be determined. Use these values to determine the respective R/S ratios. Kindly show all workings.

As an introductory lab in biology class, Mr. Schoder has you conduct an experiment to practice using the steps of the scientific method. Each group will be given 3 planting kits which include pots, sol and seeds. Students are going to plant their seeds and grow their plants for the first week. Once the first week has passed and the seeds have sprouted, groups are going to divide their planters into three groups, one group of plants will receive OmL of water per day. another will get Sml of water per day and the third will receive 10ml of water per day. Students will measure and record the height of the plants once a week for 6 weeks. During the experiment the students found that after the 6 week period the plant that received Oml of water died and had a height of Ocm. The plant that received 5ml of water per day reached a height of 50cm and the plant that was watered 10mL of water per day…
