A woman has a child and sues a man for child support, claiming that he is the father. She is blood Type A, her child is blood Type O, and the man is blood Type B. The man says that this proves that he is not the father, but the judge in this case says it proves no such thing. Can a child with Type O blood be the father’s child? Prove either the father or the judge correct by using evidence with a punnett square.
Answer:
If both parents have an O allele, then the child could be O.
Explanation:
If the mom is AO and the dad is BO, there is a 25% chance of having an O child
A O
B AB BO
O AO OO
Yes, it is possible for a couple with mother having blood group A and father blood group B to have a child with blood group O.
Blood group or blood type is the classification of blood on the basis of the antigens present on the surface of red blood cells.
There are four main blood groups or blood types which include A, B, AB and O. Blood group of a person is determined by the genes which they inherit from their parents. Each group can be either RhD positive or RhD negative, which means in total there are eight blood groups present in human beings.
The punnett square for this couple is attached with the answer. Here, the genotype of mother will be AO and the genotype of father will be BO. Here, A and B are dominant on O blood group.
Therefore, it is possible for this couple to have a child with blood group O.

Cottontail rabbits closely resemble the fall and winter plants in which they hide
Answer:
In earlier generations, the rabbits that looked most like their surroundings survived and reproduced.
Explanation:
The cotton-tailed rabbits consist of 20 species that are found in America and have stubby tales with white under them. They're distributed over north, central, and southern America. They live in nests called forms, have an average life span of 2 years. Due to their camaflugeous nature, they change their coat color twice every year to protect themselves from predators.Abby has blue eyes like her father. Where is the trait found?

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.

Answer:
False
False its faster! Hope this helps! More information here! Answer: An area going through secondary succession reaches its climax community faster because the area begins with some soil and some plant and animal species. An area that goes through primary succession, on the other hand, begins with no soil and no organisms, so reaching the climax community takes longer.

CUAL ES LA CONCENTRACIÓN DE OXÍGENO EN EL AIRE EN LA PAZ (BOLIVIA) CARTAGENA, Y COLOMBIA
Answer:
La concentración de oxígeno tanto en La Paz (Bolivia), como en Cartagena y en Colombia es la misma. Lo que se modifica según las alturas a las que se encuentran esas ciudades es la presión del aire, que a mayor altura menor presión. Esto hace que haya menor cantidad de oxígeno disponible para nuestro cuerpo.
Explanation:
Se dice que a 3000 metros sobre el nivel del mar la disponibilidad de oxígeno para el cuerpo humano se reduce en un 30% aproximadamente, y a más 5000 metros al menos al 50%. Esto puede producir hipoxia, o falta de oxígeno en sangre. También se le llama mal de altura o soroche.
La respiración pulmonar se debe a un intercambio de gases y gracias a diferencias de presiones en el aire que inspiramos y en nuestro cuerpo y sangre.
En ciudades como La Paz, que se encuentra a más de 3000 metros sobre el nivel del mar, se suele encontrar en la sangre de las personas una menor saturación de oxígeno que en aquellas que viven en ciudades a altitudes cercanas al nivel del mar.
Which statement about the effects of natural events and human activities is true?
A.The environment is not usually affected by natural events
B.Human activities and natural events can damage the environment.,
C.Natural events always have a positive impact on the environment.,
D.All human activities change the environment in a negative way.
Answer:
B. Human activities and natural events can damage the environment.,
Explanation:
Human activities are those activities carried out by a human being. The environment is being degraded daily as a result of the activities of man as well as natural occurrences e.g earthquake, tsunami, wild fire etc.
Human activities also called anthropogenic activities that damage the environment include sewage pollution, burning of fossil fuels, oil spillage etc. Hence, according to this question, human activities and natural events can damage the environment.

Answer:
5= mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

difference between parallel venation and reticulate venation
this is where you can get
The difference between parallel venation and reticulate venation is in parallel venation, the vein of the leaf blade is in a parallel pattern, and in reticulate the vein of the leaf blade is a net or web-like structure.
What is venation?Venation is the pattern of veins present in the leaves. There are different patterns of veins present in the leaves, parallel venation, for example, banana leaf, and reticulate venation, for example, papaya leaf.
Thus, In contrast to reticulate venation, where the vein of the leaf blade is arranged in a net-like pattern, parallel venation has the vein of the leaf blade arranged in a parallel pattern.

Si un RNA mensajero (mRNA) esta formado por 700 nucleótidos, ¿puede ser posible que
la cadena peptídica sintetizada tenga tan solo 70 aminoácidos?
Answer:
Si, esto es posible ya que para llegar a su forma madura el ARN mensajero sufre un procesamiento conocido como empalme alternativo donde su longitud se reduce drásticamente mediante la eliminación de regiones no codificantes (intrones) presentes en el trascripto primario
Explanation:
En células eucariotas, la transcripción refiere al proceso donde un gen es usado como templado para generar un ARN mensajero (ARNm) inmaduro conocido como pre-ARNm, el cual contiene regiones cortas codificantes (exones) y regiones largas no codificantes (intrones). Durante el proceso de empalme alternativo, también conocido como splicing alternativo, este pre-ARNm sufre un procesamiento mediante el cual los intrones son eliminados y los exones son retenidos y empalmados, con lo cual el ARNm maduro final reduce drásticamente su longitud original. En el caso arriba descripto, una proteína con 70 aminoácidos resultaría de la traducción de un ARNm maduro que posee 210 bases nucloetídicas, ya que cada triplete de nucleótidos o 'codón' corresponde a un sólo aminoácido agregado a la cadena polipeptídica durante la síntesis proteica en los ribosomas.
