Question
Chapter 40.6, Problem 3CC
Summary Introduction
To explain:
The process how the density-dependent birth rate of dune fescue grass exemplifies negative feedback in the biological system.
Concept introduction:
The species of the dune fescue grass (Vulpia fasciculate) grow rapidly and form dense covering on the land region in the presence of nutrients, carbon dioxide, oxygen and sunlight. The rapid growth causes the scarcity of food, nutrients, oxygen and sunlight. This causes the inhibition of the growth and proliferation of the plant species.

Question:-
Franco and Nobel (1989) discovered that there are downsides to having a nurse plant for young cacti. They found that while young cacti survive more often, they grow slower than young cacti without a nurse plant. What are the authors' two explanations for why that happens?
Explain why blue tits in France were unable to experience local adaptation (i.e., timing reproduction to coincide with peak insect emergence when breeding on holm oaks)? Describe the conditions under which local adaptation to holm oaks could occur?

- Think critically A student want to study the Moulting in mosquitoes. He very much clear about the mechanism of Moulting but unfortunately he forgot to choose the right hormone. He has two types of hormone, juvenile hormone and moult inhibiting hormone. He tries with both the hormone in mosquitoes and observed the results. What will be the results to the mosquitoes development with the juvenile hormone and the moult inhibiting hormone. It's not an assignment or complex question. It's an entamology question. Kindly answer and Don't reject it under complex or essay type. It's not comes under those category. Thank youarrow_forwardExplain in short plz. Asap. Thanks Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, andgene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive.arrow_forwardINTERPRET DATA Compare the two graphs in Figure 1-17.

How does it deal with these pressures?arrow_forwardThe Problem: Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs. The specific bean on which each egg is laid determines the future success of the larva that develops from that egg. Choosing where to lay an egg is the most important decision a female bean beetle will make for her offspring, yet even within one bean species the seeds available may be very different in quality. Seeds vary in size (even if from the same plant), so the amount of resource available to larvae on different beans will not be the same. Seed mass may vary by as much as 50% among mung beans purchased in a local store, a species on which Callosobruchus develops normally and may complete its lifecycle. During what stage do beetles find the majority of their nutrition? tadpole larval juvenile adultarrow_forwardThe Problem: Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs.
