Answer:
Carbon compounds plants passing in the form of carbohydrates, protein, and lipids along the food chains to the animals.
Explanation:
In the food chain, plants produce glucose as food and cellulose for their cell wall. Animals eat plants for their food. So through the food chain, carbon presents in plants move to animals in the form of lipids, proteins, and carbohydrates mainly.
This is a symbiotic relationship between the Boxer crab and sea anemone.
The symbiosis is a type of relationship between two species which has benifit for both the participating organisms.
Here in case of boxer crab, the crab gets the help from the sea anemone in the form of protection. The sea anemone chases the predators and thereby saves the organism from being hunted.
On the other hand, the sea anemone gets food from the crab's prey which he hunts.
So there's a benifit for both.
B) Option 2: Photosynthesis
C) Option 3: Use of language and complex communication
D) Option 4: Exoskeleton
Answer:b
Explanation:
The special characteristic that separates humans from all other living organisms is our ability to use language and complex communication. We can share a wide range of thoughts and feelings through a variety of symbolic communication systems, a capability no other creatures possess.
The distinct characteristic that differentiates human beings from all other living organisms is 'Option 3: Use of language and complex communication'. Humans have a unique capacity to express a limitless range of ideas and emotions through complex systems of symbolic communication including language, writing, art, mathematics, and science. Other organisms communicate, but none have the ability to create, manipulate, and pass down complex symbolic systems like humans.

B. A store is hiring a lot of immigrants to work on the weekends.
C. A restaurant is letting their waiters keep all of their own tips.
D. Two large, national companies are merging and laying off workers.
ANSWER: A. A factory does not clean its workspace every night.
EXPLANATION: The National Consumer's League is an American consumer organization founded in the year 1899. It advocates for consumers on marketplace and workplace issues. They voiced for safer and secure workspace, fair working conditions, protected workers from exploitation by employers, promoted food inspection and advocated for child labor restrictions, the limiting of work hours and establishing minimum wage laws for women. So, it can be guessed that they are protesting for factory's clean workplace.
Answer;
-Independent variable
Explanation;
-An independent variable is defines as the variable that is changed or controlled in a scientific experiment. An independent is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable on the other hand, is the variable being tested and measured in a scientific experiment.
-A change in the independent variable directly causes a change in the dependent variable.The independent and dependent variables may be viewed in terms of cause and effect.
Answer:
In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1
Explanation:
Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.
Lidocaine does not affect the generation of action potentials because it blocks voltage-gated sodium channels.
In the context of neural signaling, lidocaine often functions as a local anesthetic by inhibiting voltage-gated sodium channels, which are necessary for the propagation of action potentials. If the action potential at R1 was not affected in the presence of lidocaine, it could be due to several reasons. One possibility is that lidocaine was applied upstream or downstream of R1, which would not directly impact the action potential at R1. Another possibility is that there are no voltage-gated sodium channels at R1 to be affected by lidocaine.
