Answers
About the question:
You will find the chart in the attached files
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.

ians do not rely on their lungs alone for breathing in air. They need the skin a
adequate intake of oxygen. Which of the statements below explains the reason
mphibians have only one lung to breathe in air
nly a small amount of air enters the lungs as they breathe.
surface area of the lungs are small compared to other terrestrial vertebrat
surface area of the lungs do not have folds compared to other terrestrial v
Answers
Answer:
These lungs are primitive and are not as evolved as mammalian lungs. Adult amphibians are lacking or have a reduced diaphragm, so breathing through the lungs is forced. The other means of breathing for amphibians is diffusion across the skin. To aid this diffusion, amphibian skin must remain moist.
Two common respiratory organs of invertebrates are trachea and gills. Diffusion lungs, as contrasted with ventilation lungs of vertebrates, are confined to small animals, such as pulmonate snails and scorpions.
Explanation:
Amphibians utilize gills for breathing early in life, and develop primitive lungs in their adult life; additionally, they are able to breathe through their skin.

sometimes colder than the core body temperature?
O A. So that less energy is lost in cold environments.
OB. The fingers need to be colder to protect the durability of the nails.
C. The fingers do not have thermoregulation mechanisms.
D. So that more energy is lost in cold environments.
Answers
Answer:
A. so that less energy is lost in cold environments.
Explanation:
When it’s cold outside, your body makes sure to keep the blood flowing to your core and vital organs to keep them warm. This can change the amount of blood flow to your hands and feet, making them feel cold. This is normal. The blood vessels in your hands and feet constrict (spasm) when it’s cold, to prevent heat loss from your core

21. What determines the kind of genes an organism
possesses?
Answers
Answer:
The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA.
Answer:
The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA. ... The order of bases as you go down the rungs of the ladder determine what genes an organism will have, and therefore, what traits it will have.
Explanation:
Fun facts:
Genes carry the information that determines your traits which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes. ... And chromosomes are found inside cells. Your body is made of billions of cells.

Some blackcaps that migrate to the United Kingdom have become distinguishable by certain physical and behavioral traits from blackcaps that migrate to Spain. What best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter?
Answers
Answer:
Increases.
Explanation:
There is a good effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter because there is more food available for the blackcap bird which automatically increase the population of the bird. Food is the main factor that contributes in the increase or decrease population of blackcap in the United Kingdom and prevent the removal of this bird in that environment.
why do you think Harvey placed the sea urchin cells in a hypersonic solution?
Answers
Harvey placed the sea urchin cells in a hypersonic solution in order to see the behaviour of the cell in the hypersonic solution.
What Harvey placed the sea urchin cells in a hypersonic solution?In 1940 Ethel Brown Harvey evolve a technique for separating embryonic sea urchin cells. She took a pair of embryonic cells to develop from the first cell division after Harvey's fertilization. She settles the pair of cells in a hypertonic solution, carrying double the amount of salt as that contained in seawater. Most sea urchins produce a group of early embryonic cells which is known as micromeres. Small blastomeres Harvey that form by unequal cell division at the vegetal pole of the early embryo. Harvey Sub-Sea is the first that indicated Maritime Labor Convention compliant.
So we can conclude that Ethel Brown Harvey developed a technique for dividing embryonic sea urchin cells.
