Smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one occasion, two smurfs from different groups did mate. A big-footed, white smurf mated with a small-footed, blue smurf. Three offspring resulted: one big-footed and blue and two small-footed and blue.Which statement about the inheritance of color in smurfs is most likely to be correct?
Answers
Answer:
See the answer below
Explanation:
The most correct statement would be that the blue color is dominant over the white color.
According to Mendelian law, when there are two different versions of the same gene/trait in which one is dominant and the other is recessive, the dominant version will be expressed while the recessive version only stays in the background.
In this case, the alternate versions of the same trait in the smurf are the white and blue colors. When they are mixed together in the offspring, the blue color is expressed and the white color stays in the background. It means the blue color is dominant over the white color.
Explique la importancia e incidencia del buen funcionamiento de las hormonas en el cuerpo del ser humano y que consecuencias puede tener si hay alteración en el nivel hormonal
Answers
Answer:
Las hormonas activan vías de señalización celular, con lo cual regulando el crecimiento, metabolismo y reproducción del organismo
Explanation:
Las hormonas son moléculas mensajeras que circulan a través del torrente sanguíneo para llevar a cabo diferentes funciones. Estas moléculas se unen a receptores específicos presentes en la superficie de las células con la finalidad de controlar diferentes aspectos de su funcionamiento. Las hormonas son principalmente producidas por glándulas endocrinas pero también pueden ser secretadas por células intersticiales y epiteliales.
Las hormonas se dividen cinco clases principales:
a- pequeños neurotransmisores implicados en el funcionamiento del sistema nervioso (gonadotropina, somatostatina)
b- derivados de aminoácidos que también tienen funciones neuromotoras (dopamina, catecolamina)
c- proteínicas asociadas a funciones metabólicas y del desarrollo (insulina)
d- hormonas esteroideas derivadas de colesterol (estrógenos) que regulan el desarrollo de las características reproductivas y metabólicas e inmunológicas
e- hormonas derivadas de vitaminas liposolubles A y D (retinoides) vinculados a mecanismos que previenen el envejecimiento celular
A nerve is a bundle of axons, and some nerves are less sensitive to lidocaine. If a nerve, rather than an axon, had been used in the lidocaine experiment, the responses recorded at R1 and R2 would be the sum of all the action potentials (called a compound action potential). Would the response at R2 after lidocaine application necessarily be zero? Why or why not?
Answers
Answer:
the response at R2 after lidocaine application will not be zero
Explanation:
The response at R2 after lidocaine would not be zero because it is recording the of all action potentials and some axons may be unaffected.

Organisms exhibit different types of adaptations as a means of survival. What type of adaptations do the caterpillar and the plant show in this interaction?
Answers
Answer:
The type of adaptations exhibited by both organisms depends the effects each exhibited on the other.
When natural selection acts on the variation passed from generations to generations in a population,the organism involved are best fitted to survive in their habitats.The Ability of species of organisms to be best fitted against the selective pressure,so that it is naturally selected in the population is called adaptation.It is one of the driving force of evolution.
in this scenario the caterpillar,is camouflage by its green color,which blend with that of the leaves.And therefore ensure the escape from the predators e,g birds,spiders,reptiles This is an example of structural adaptation.Since it is the structural characteristics of the caterpillar that adapted it to its environment.
Likewise in the case of the plants,despite harbouring the caterpillar it ensures it does not destroy it physiological make up,by releasing chemical substances to keep away the organisms.This is called physiological adaptation,because certain biochemical substances are diffused by the plants in response to the caterpillar (stimulus), to keep off the organisms away,to ensure the survival of the leaves.Since physiology is the study of function of an organisms,changes in biochemical and cellular reactions must be responsible for the biochemical substances produced.

A virus inserts its DNA into the DNA of another organism. C. High-energy waves like UV light or radiation physically damage the DNA. D. A repair DNA polymerase fixes a damaged DNA strand.
Answers
Answer: Option C.
High-energy waves like UV light or radiation physically damage the DNA
Explanation:
Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.
Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.

A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Answers
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.

2. How might a mutation that causes a single letter change in the DNA sequence affect
your protein structure and function?
Answers
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells

b) Shape of the RBCs.
c) Chemical composition of the hemoglobin.
d) Size of the RBCs.
e) Presence of specific glycoproteins on the cell membrane.
Answers
Answer:
) Presence of specific glycoproteins on the cell membrane
Explanation:
When specif glycoproteins(antigens) or antibody are present on a cell membrane of Red blood cell,they can be used to identify the blood type.Antigens are substances capable of triggering an immune response in a cells.
In addition,they function in transport of molecules across the RBC. They help in the maintenance of the RBC,and aiding the arrest of cells capable of causing diseases to the body.
Therefore,they are good determinants of blood types,based on this two types of antigens present in a blood type.
These two antigens used for classification of blood types are the 1-the ABO antigens 2,the Rhesus antigens.
Essentially,when a WBC produces an antibody ,which is a molecule that defends the body,If this is not compatible,the antibody will recognize it as a foreign body and attack it.Thus such blood types are not compatible. Thus the antibody-antigen reaction are good for knowing and classify blood types.
Antigen can also be glycoprotein,carbohydrate or glycolipids.
Generally blood types are inherited from both parents.Therefore the antigen present on the RBC are combination of the alleles from each parent.
