"In the snake experiment, what was the basis for the hypothesis that mimic species benefit from looking" like unrelated harmful
Fantom [35]

Answer:

The contrast in coloration was pivotal to determine if predators attack snakes based on their colors.

It was for studying MIMICRY in snakes.

Assuming all the.snakes were the same the number of attacks will not indicate anything about the effect of the colored rings.

This question on the need for provision of a controlled experiment during experimental investigation. Thus in order to test the effect of a particular condition,another contrasting condition must be provided to determine if the condition under investigation is the actual results obtaned or the influence of other factors in the environment or in the experiment.

The change in the color of the ring is the VARIABLE .In the artificial snake the variable is the presence of this coloed rings against its absence in this snake.

since it changes in the artificial snake

astraxan [27]

Complete question:

17. In the 1950’s a young woman sued film star/director Charlie Chaplin for parental support of  her illegitimate child. Charlie Chaplin’s blood type was already on record as type  AB. The mother of the child had type A (AO) and her son had type O blood (OO).

a. Complete a Punnett square for the possible  cross of Charlie and the mother.

b. The judge ruled in favor of the mother and ordered Charlie Chaplin to pay child  support costs of the child. Was the judge correct in his decision based on blood typing  evidence? Explain why or why not. *refer to any Punnett squares to support your answer.

Answer:

The judge committed a mistake in his decision. There are <u>no chances</u> for this couple to have a child who has 0 blood type.

Explanation:

<u>Available data:</u>

  • Charlie Chaplin’s blood type was AB
  • The mother of the child had type A (AO)
  • The son had type O blood (OO).

Cross: Charlie Chaplin x The Woman

Parental)    IAIB    x    IAi

Gametes) IA   IB       IA     i

Punnett square)    IA          IB

                      IA   IAIA      IAIB

                        i    IAi        IBi

F1)  1/4 = 25% of the progeny would have IAIA genotype, blood type A

      1/4 = 25% of the progeny would have IAi genotype, blood type A

      1/4 = 25% of the progeny would have IAIB genotype, blood type AB

      1/4 = 25% of the progeny wouldl have IBi genotype, blood type B

According to the results of the cross observed in the Punnett square, there are no chances for this couple to have a child who has 0 blood type.

Blood type 0 can only be produced by two recessive alleles i, one inherited from each parent. The mother could provide the recessive allele because she is IBi, but Chaplin could not pass to his progeny any recessive allele.

The judge committed a mistake in his decision.

Where do the branches of the bronchial tree ultimately end? 2. list the steps of the pulmonary circuit of the cardiovascular sys
Aneli [31]
1. The branches of the bronchial tree ultimately ends at the alveoli.
Bronchial tree consist of bronchi, bronchioles, and alveoli. Bronchi are formed as the lower part of the trachea divides into two tubes. Bronchioles are smaller tube divisions of the bronchi. It walls contain smooth muscle and no cartilage. Alveoli are tiny ends of the alveolar ducts, which functions as the site for gaseous exchange. 

2. Blood flows from the left atrium; mitral (bicuspid valves), the left ventricle, aortic valve, aorta, veins and heart, right side of the heart, superior and inferior vena cavae, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary trunk, pulmonary artery, lungs, pulmonary veins, then back to the heart...

3. Arteries and the veins differ in structures and they way they functions; Arteries carry oxygenated blood away from the heart to the body (except pulmonary artery) while veins carry deoxygenated blood back from the body to the heart (except pulmonary veins). A structural differences includes; the veins contain valves while arteries lack. Arteries have narrow lumen while veins have wide lumen. Lastly, blood carried by veins has higher pressure compared to blood carried in vessels.

4. The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and the bronchioles. Blood moves in and out of the lungs throgh the pulmonary arteries and veins that connect to the heart.

5. The cartilage rings of the trachea
They are strong but flexible tissues which support the trachea or the windpipe while still allowing it to move and flex during breathing. Additionally these cartilage rings are C-shaped to provide room for the esophagus, which lies along the back side of the trachea.

6. Functions of the larynx includes;
To protect the airway from choking on material in the throat
to regulate the flow of air into our lungs
The production of sounds used for speech 
Larynx is part of the respiratory system and is located between the pharynx and the trachea. Humans use larynx to breathe, talk and swallow. 

7. Structures that make up the pathway of air through the respiratory system starting with the external nares; We start with; External nares, nasal cavity, internal nares, nasopharynx, laryngopharynx,oropharynx, larynx, trachea, primary bronchus, secondary bronchus, tertiary bronchus, bronchiole, terminal bronchiole, respiratory bronchiole, alveolar duct, alveolar sac and alveolus.
