Answer:
1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.
2. neurons that detect chemicals such as those found in food. Chemoreceptors.
3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.
4. the structure that gives the response to an environmental change. Effector
5. neurons that detect electrical fields. Electroreceptors.
6. secretion of hormones into the blood stream to affect distant processes. Endocrine.
Explanation:
An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.
There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.
Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.
The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.
There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

A trait that does not offer members of a population a great advantage will most likely
A. increase the reproductive rate in successive generations
B. decrease in frequency in successive generations
C. appear at the same frequency in successive generations
D. undergo a series of mutations in successive generations
A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.
What is theory of natural selection?
According to Charles Darwin in his theory of natural selection, organisms must compete for scarce resources. Only the fittest can survive. The fittest are organisms that have undergone the required genetic changes that increases their chances of survival. They pass on these genetic changes to the next generation or offspring.
When availability of food decreases, organisms begin to change genetically as they struggle for scarce resources thereby leading to variation in a population. All organisms must compete for survival. Natural selection continues to occur even today.When organisms struggle to survive, they usually mutate to increase chances of reproduction.
Therefore, A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.

The diagram shows the same type of molecules in area A and area B.
With the passage of time, some molecules move from area A to area B. This movement is the result ot the process of
1. phagocytosis
2. pinocytosis
3. diffusion
4. cyclosis
Answer:
3. diffusion, because molecules are moving from a high concentration(A) to a low concentration(B)
Diffusion is the net flow of matter from a location of high concentration to a region of low concentration as a result of the random mobility of molecules. Both stopping and reversing this process are not possible. Thus, option C is correct.
What are the main mechanism in diffusion process?The molecules' kinetic energy causes random motion, which causes diffusion. This mechanism happens in simple diffusion without the help of a carrier protein.
The molecules travel from an area of high concentration to an area of low concentration due to their random mobility.
Chemicals flow across the plasma membrane from areas of high concentration to areas of low concentration in cells to maintain an equilibrium (balance) of internal substances.
This implies that if there are more items inside the cell than outside, they will go outside and vice versa. It happens when the medium around the cell contains more water than the cell itself.
Therefore, This movement is the result of the process of diffusion.

Match each idea about evolution to the person or group where it originated from the drop down menu
Hello. You did not present the ideas about evolution to which the question refers, which makes it impossible for your question to be answered. However, I will try to help you in the best possible way, showing you the main ideas about evolution and the people who originated them.
According to Jean-Baptiste organisms evolve as a way of seeking perfection.
According to the ancient Greeks and Romans, all living things are in a constant process of change. This change causes evolution and when a living being evolves it causes the evolution of another living being, since everyone is connected and related.
According to Darwin, evolution occurs over time and through an ancestor. For him All living beings have a common ancestor, which evolved over time and generated new species. Darvin also believes that any characteristic acquired by evolution could be passed on to the descendants.
According to Malthus, living beings generate a number of descendants disproportionate to the resources necessary for their survival and this causes evolution.

During one year, seven coyotes in a population die. Eight immigrate into the population, but none emigrate. If the overall population growth is 13 coyotes, what was the birth rate of coyotes during the year? Use this formula: population growth = (birth rate + immigration) – (death rate + emigration) 7 11 12 15
Answer:
Death rate= 7 coyotes
Immigration= 8
Emigration= 0
Population growth= 13
Let’s suppose that the birth rate for the given population is x.

Answer:
Unicellular prokaryotes that live in dust: Eubacteria
Unicellular eukaryotes that line in pond water: Protista
Multicellular eukaryotes that live all over the planet and consume food: Anamalia
Unicellular prokaryotes that live in volcanic ash: Archaebacteria
Multicellular eukaryotes that have cell walls and are heterotrophic: Fungi
Multicellular eukaryotes that have cell walls and are autotrophic: Plantae
Explanation:
Prokaryotic organisms can be classified into two groups: Eubacteria and Archaebacteria. Eubacteria (i.e.,“true” bacteria) are unicellular prokaryotic microorganisms that live in normal environmental conditions. On the other hand, Archaea (Archaebacteria) are prokaryotic older organisms that thrive in extreme conditions (in this case, volcanic ash). Moreover, eukaryotic organisms can be classified into four kingdoms: Protista, Plantae, Fungi and Animalia. Protista are unicellular eukaryotes that live in different aquatic environments (i.e., oceans, ponds, streams, etc). Animals are multicellular, mobile, heterotrophic (i.e., organisms that cannot produce its own food) organisms whose cells lack walls. Fungi are heterotrophic organisms that acquire their food by absorbing dissolved organic compounds, whose cells have cell walls (but they lack chloroplasts). Finally, plants are multicellular autotrophic (i.e., organisms that produce their own food) organisms whose cells contain walls and chloroplasts (to produce food by photosynthesis).
