Answer:
b) x: fin
y: lateral line
z: swim bladder
Explanation:
The dorsal fin is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.
The Lateral Line is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.
The swim bladder is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.

(c) dry mud

Answers
Answer:
(a). soft substrates
Explanation:
Mobile organisms can be measured by both direct and indirect methods. Direct methods may involve observing the actual behavior (e.g., scoring via timing). Moreover, indirect methods are those where the technique used depends on the species being examined, collecting information such as through recording of tracks in the soft substrate (e.g., mud, sand, snow), presence of fur/feathers, droppings (mammals), etc. For example, indirect observation of insects may involve the determination of exoskeletons, sounds, etc.

How can histograms help you describe a population? Use the word bank above to help you explain your answer.
Answers
Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
Explanation:
A histogram is a graphical representation of a variable using bars. In such a bar, its area is proportional to the frequency of the values represented. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest. On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented. Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).
Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.
The population can be given as the number of people living in a specific area. The histogram represents the population, with frequency as the function of the area.
What is a histogram?A histogram is the graphical representation of the data in the form of bars. The population is given as the number of people in an area.
The population in the area is termed as frequency. The bar graph represents the frequency of population as the function of the area and thereby helps in the determination of the population.

reasons why transpiration is important in plant
Answers
Answer: Transpiration is how water leaves a plant. It is important because water is needed for photosynthesis and because water cools a plant off.
Check the image attached
Explanation
Explanation:
Transpiration is how water is removed from a plant. Most transpiration happens from the leaves of a plant. Water is absorbed through the root hairs, is transported through the plant due to osmosis, and exits through the stomata and evaporates.
Transpiration is important because water is needed for photosynthesis and because water cools a plant off.

What is the relationship between the economy and environmental quality? (3 points)
There is no relationship between the economy and environmental quality.
Generally speaking, better economies are associated with worse environmental quality.
Generally speaking, environmental quality initially declines and then improves as an economy grows.
Generally speaking, better economies are associated with better environmental quality.
Answers
Answer:
There is no relationship between the economy and environmental quality.
Environmental quality is a term related to different environmental cues such as, for example, air/water pollution, presence of noise, access to open public spaces, the visual impact of buildings, etc. Environmental quality can affect human health and the quality of life of the individuals in a given area/city. For example, water contamination is linked to the transmission of different diseases (e.g., gastroenteritis; encephalitis, hepatitis A), thereby negatively affecting human health and the quality of life of persons who don't have access to potable water. Similarly, poor air quality can be associated with respiratory diseases and cancer. The improvement in environmental quality does not necessarily involve economic resources. It is possible to improve environmental quality by:1-protecting people against climate change;
2-improving water/air quality;
3-reducing pollution;
4-reducing waste and increasing recycling;
5-limiting the visual impacts of new infrastructure; etc.
In conclusion, there is no direct association between the economy and environmental quality.
