Answer:
Without rain, there would more than likely be no collection of water for animals to drink such as ponds, lakes, rivers, etc. Rain, in addition to providing these animals with water to drink, also provides them with their natural habitats such as fish, mosquitoes, and other water creatures. Without rain, animals would merely perish, and soon, humans would as well.

According to the food chain shown, about how much energy from the grasshopper trophic level is transferred to the frog trophic level?
The amount of energy transferred to frog is 10% of the energy contained in grasshopper.
This is a representation of energy levels and distribution in a food chain in an Ecosystem. When a group of organism represent the same level in a food chain, in an ecosystem ,this is trophic level. Food chain represent a linear representation of nutrients and therefore energy distributions in an ecosystem.
Basically, in an ecosystem, there is always reduction in energy transfer from one trophic level to another by 10%. This is because, as the energy is transferred from the producer (green plants) to the primary consumer, the hopper, only 10% of the available energy will pass through to the hopper because 90% of the energy will be used by the green plants for metabolic and other physiologic activities. As this is transferred to the next trophic level, the Frog, this will be reduced (for the same reasons) so that 10% of the energy received by the grasshopper is transferred to the frog.
Practically, if 100,000Kcal of energy was obtained by hopper from the primary producer,10,000kcal(10%) of 100,000 will be transferred to frog.
This 10% occurs at each trophic levels.

Why would Humans would not be able to repair and grow your muscles without bacteria
Answer: the genes of those microbes are more responsible for human survival than the genes of our own human body! Not all of the bacteria in our bodies are bad. Just as we cannot live without air and water, we cannot live without our microbes. So, the cells that make our muscles function are not even our own body cells!

1. Will loves to go fishing in the coastal estuary. He brings home his catch every weekend and bakes the fish for dinner. The next time he goes to his favorite fishing area, a sign is in place, warning residents of high heavy metals in the water. Which statement best explains the impact of eating fish from the estuary?
Heavy metals can biomagnify in large fish, making human consumers ill.
Heavy metals are water soluble; humans can eat them in small amounts.
Large fish will die from the heavy metals, but small fish can be consumed.
Will should avoid small fish but can collect large fish with less heavy metals.

how is the scientific method used in earth science (it was due yesterday)
Answer: The steps used in scientific methods are to ask a question, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, and communicate results. A controlled experiment tests only one factor at a time so that scientists can determine the effects of changes to just that one factor.
Answer:
The scientific method is the gold standard for exploring our natural world. You might have learned about it in school, but here’s a quick reminder: It’s the process that scientists use to understand everything from animal behavior to the forces that shape our planet—including climate change.
All of the following among A-D apply to toll-like receptors EXCEPT A. they bind to PAMPS B. they induce the release of cytokines when activated C. they directly lyse bound pathogens D. when stimulated, they activate the immune system of the body E. there are no exceptions, A-D are all true
The toll-like receptors do NOT directly lyse bound pathogens (Option C). These protein receptors play fundamental roles in the innate immune system.
Toll-like receptors (TLRs) are single-pass membrane-spanning protein receptors that play fundamental functions in the innate immune system.
TLRs are differentially expressed on the surface of antigen-presenting cells (i.e., macrophages and dendritic cells) in order to recognize evolutionary conserved antigenic domains in different pathogenic microorganisms (e.g. bacteria).
TLRs initiate innate immune responses such as, for example, inflammatory responses, by identifying conserved pathogen-associated molecule patterns (PAMPs).

organisms that have bigger genomes are more complex than organisms with smaller genomes.
Given that breaking bonds requires energy and forming bonds releases energy, explain how we know that cellular respiration releases energy overall?
because it's overall final fee energy value is less than it's initial, meaning that it has a negative free energy amount. therefore, there is a net release of energy in cellular respiration, so we know it releases more energy than it invests into the bonds of its products.
How is glucose stored in skeletal muscle? Why cannot glucose be released from skeletal muscles to maintain blood glucose concentration?
Answer:
In skeletal muscles with low glycogen, glucose will be stored as muscles glycogen.
Skeletal muscles are unable to release glucose because muscles lack glucose 6 phosphatase. Also, muscles glycogen is mainly a local energy substrate for exercise, rather than an energy source to maintain glucose concentration during fasting.
