Quorum-sensing contributes to the ability of bacterial colonies to congregate into nearly solid masses which act as barriers to effective decontamination and sterilization called:
Biofilms are formed when bacteria congregate into a nearly solid mass. This occurs when bacteria use quorum sensing to communicate with each other and create pathways for cells to attach to and form a matrix.
The matrix shields the cells from external forces and helps to protect the bacteria from antibiotics, desiccation, and extreme temperatures. Biofilms can form on just about any surface, including medical and surgical instruments, water pipes, and even on the surfaces of plants and animals.
The formation of biofilms makes it difficult to decontaminate and sterilize, since the bacteria are protected within the matrix and can withstand harsh chemicals and extreme temperatures. Biofilms are also highly resistant to antibiotics, making them difficult to eradicate.

B) A. FALSO.
B. VERDADERO.
C. VERDADERO.
D. VERDADERO.
c) D. Contracción de los bronquios.
d) A. Axon, dendritas, cuerpo neuronal.
Explanation:
B) A. FALSO. La médula espinal es una estructura tubular larga y delgada, formada por tejido nervioso, que se extiende desde la médula oblonga del tronco cerebral hasta la región lumbar de la columna vertebral. El cerebro junto con la médula espinal forman el sistema nervioso central, y particularmente la médula espinal es la vía para transmitir los mensajes que envía el cerebro al cuerpo y del cuerpo al cerebro. Entonces no se ocupa de la apreciación de sensaciones.
B. VERDADERO. El cerebelo desempeña un papel importante en el control motor pero también puede estar implicado en algunas funciones cognitivas, como el lenguaje así como en el control emocional, la regulación de las respuestas de miedo y placer,. Aunque sus funciones relacionadas con el movimiento son las más importantes.
C. VERDADERO. El cerebro es la porción mas grande del encéfalo (órgano dentro del cráneo) y está formado por dos hemisferios. También comprende varias estructuras subcorticales, como el hipocampo, los ganglios basales y el bulbo olfativo. Es la región más grande del sistema nervioso central y sus funciones incluyen la iniciación y coordinación del movimiento, tacto, visión, oído, regulación de la temperatura, el razonamiento, las emociones, aprendizaje, etc.
D. VERDADERO. La médula oblonga o bulbo raquídeo es una larga estructura en forma de tallo que constituye la parte inferior del tronco encefálico. Se encarga de conectar al cerebro con la médula espinal, y es responsable de varias funciones del sistema nervioso autónomo que incluyen el control de la ventilación a través de señales procedentes de los cuerpos carotídeos y aórticos como también el control cardiovascular al regular los latidos cardíacos. Aunque también está relacionado con otras funciones tales como la tos, estornudo, reflejos del vómito y la deglución.
c) El sistema nervioso parasimpático (SNP) es una de las tres divisiones del sistema nervioso autónomo, siendo las otras el sistema nervioso simpático y el sistema nervioso entérico. El sistema nervioso autónomo se encarga de regular las acciones inconscientes del cuerpo, en donde el sistema parasimpático es responsable de la estimulación de las actividades de "descanso y digestión" cuando el cuerpo está en reposo, especialmente después de comer. Controla por ejemplo, la salivación, el lagrimeo, la micción, la digestión y la defecación. Su acción se describe como complementaria a la del sistema nervioso simpático, responsable de estimular las actividades asociadas a la respuesta de "lucha o huida". Entonces los procesos que son resultado de la acción del sistema nervioso parasimpático son:
D. Contracción de los bronquios. El SNP controla órganos en situaciones o momentos que requieren una respuesta rápida.
d) Una neurona o célula nerviosa es una célula eléctricamente excitable que se comunica con otras células a través de conexiones especializadas llamadas sinapsis. La misma consta de:
A. Axon (proyección larga y delgada de una célula nerviosa que conduce impulsos eléctricos conocidos como potenciales de acción), dendritas (extensiones protoplásmicas ramificadas de una célula nerviosa que propagan la estimulación electroquímica recibida de otras células neuronales al cuerpo celular), cuerpo neuronal (o soma, es la parte bulbosa de una neurona que contiene el núcleo celular)

Humans has the same transformation as other animals even though humans are special.
10. Summary/reflection:
Given that whales and other mammals resembled other mammals in terms of their skulls and other sculptures, based on the fossil evidence, humans have undergone evolutionary transitions.
The transition from land animals to whales is one of the most well-known instances of a supposed change cited by the evolution contingency in the opening of the program. The fossils of Pakicetus, Ambulocetus, Rhodocetus, Dorontid, and Basilosaurus show that this transition can be explained. Pakicetus only has a small portion of its cranium to display, as opposed to a whole transitional fossil.
The program portrays Ambulocetus as a fully preserved fossil of an aquatic mammal with legs, yet this is a stretch of the fact because the animal's skeleton was actually discovered to be extremely fragmented. Rhodocetus is solely represented in the series by a skull.

What is the probability that two parents with the genotype AaBb will produce an offspring with the genotype AaBb?
The probability of parents with the AaBb genotype producing offspring with the genotype AaBb is 4/16. Thus the correct answer is (b) 4/16.
The Punnett square method is used to forecast the prospective offspring from a certain cross based on the gametes of the parents. The parents carefully create the gametes that are arranged in a checkerboard pattern so they can understand all the potential children that can be generated. The likelihood of each prospective offspring can be determined using the checkerboard method. In the cross, there are four gametes produced by each of the two dihybrid parents. As a result, the hybrid has the capacity to produce a total of 16 offspring. Out of the 16 possible combinations, only four types of offspring can have the AaBb genotype.
Parents: AaBb*AaBb
Genotypes: AB Ab aB ab * AB Ab aB ab

What was the most significant conclusion that Mendel?
The most significant conclusion that Mendel drew from his experiments is that 'Traits are inherited in discrete units one from each parent'.
The main conclusion that Mendel drew from his experiments is that traits are inherited from each parent in his individual units and are not the result of interbreeding. He called these separate substantive factors pairs.
Mendel's main conclusion, drawn from his experiments with peas, is that factors are inherited as discrete units and do not exhibit mixing.
The peas he used in his experiments were a good choice because of their distinct contrasting traits, hermaphrodite flowers, short lifespan, and less variation in results with crosses.All monohybrid and dihybrid crosses he considered phenotypic and genotypic ratios were identical.
Genes are now discovered to be pieces of DNA that reside on chromosomes, but Mendel did not know which genes (Mendelian factors) consisted. A study of chromosome behavior was carried out by Sutton and Boveri with the aid of a microscope. They later compared it to the behavior of factors and genes.
