Question
Chapter 45.2, Problem 1TC
Summary Introduction
To explain: The reason underlying the given hypothesis and an experiment that could help to test the hypothesis.
Introduction: Pollen grains are male gamnetophytes of seed palnts. Pollen grains have a coating of sporopollenin that protects them during pollination. Pollen grains are found on the anther of the stamen and are transferred to the stigma and then the male gametes fertilize the ovum and lead to the formation of a zygote.

Think about the Bucket Orchid's use of secondary metabolites. How does the Bucket Orchid use secondary metabolites to “manipulate” the bee’s activities? Carefully assess each event you see in the video. There is evidence for 5 specific and distinct ways that the orchid 'manipulates' the bees activities (so there are 5 distinct possible answers). Please briefly describe 4 uses of secondary metabolites by the orchid and make sure you are specific and each one is distinct from the others.

I’m not quite understanding this question can you explain which best describes bottleneck?
Recently, scientists have become concerned that bees are dying in large numbers. One of the primary
suspects has been a new kind of pesticide. Now, other researchers are investigating the potential
toxicity of metal pollution on bees.
Soil may become contaminated by exhaust from vehicles, industrial machinery, and farming equipment.
In a study that allowed bees to forage from flowers that were uncontaminated or contaminated with
nickel and aluminum, bees avoided the flowers that were contaminated with nickel. However, the bees
did not discriminate against the flowers that were contaminated with aluminum. This may indicate that
the bees foraged in the past on aluminum-contaminated flowers and had become tolerant or immune to
the aluminum. The results of the study may have implications for phytoremediation, the practice of
growing plants on polluted soil to remove contaminants.
1. Which are the effects of metal toxicity of metal pollution in bees?
2. What is phytoremediation? Is it…

The students got higher scores in the exam because the class size is small. 6. A farmer observed that during seasons of drought and soil becomes more saline, his tomato plants were more susceptible to fungal infection. The combination of salinity and drought and the infestation of fungi led to significant reductions in fruit yield and size. The farmer proposes a general hypothesis, “Salinity and drought affect the severity of fungal infection in tomato plants.”arrow_forwardIncrease K1 to shift the N1-intercept out for the pathogen O No further engineering is needed because there is a steady state point Decrease 12 to shift the N2-intercept up for the pathogen Increase K2 to shift the N2-intercept up for the probioticarrow_forward
