The environmental problem which likely caused all of these problems is smog from city areas is causing acid rain.
A chemical reaction that starts when compounds like sulfur dioxide and nitrogen oxides are released into the air begins is what causes acid rain. These substances have the ability to soar very high into the atmosphere they combine and react with water, oxygen, and other chemicals to form smog which will form acid rain, which is a form of pollution that is even more acidic. In affected areas, dead or dying trees are common sights. Aluminum is leached from the soil by acid rain. that both animals and plants may be harmed by aluminum. Minerals and nutrients that trees need to grow are also taken out of the soil by acid rain. Fish are directly harmed by elevated aluminum levels and low pH. Additionally, fish are less able to compete for food and habitat due to chronic stress brought on by elevated aluminum levels and low pH, which may or may not result in the death of individual fish.

9- The results of this type of DNA analysis are often used to help
determine *
A) the number of DNA molecules in an organism
B) if two species are closely related
the number of mRNA molecules in DNA
OD) if two organisms contain carbohydrate molecules
Answer:
B) if two species are closely related.
Explanation:
DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.

If your parents are the P generation, what generation are you?
Answer:gen z
Explanation:
Base your answer to this question on the following information: You have isolated a primary signal factor from the blood of a space alien, which you name XFF (for X-files factor). You also have Isolated various types of alien cells which appear to Interact with XFF. Based on preliminar data, you think that XFF could be similar to one of three compounds normally found in human blood: epidermal growth factor (EGF), epinephrine, or estrogen. Which of the following would best be used to demorstrate XFF is most like EGF?
A. exposure of cells to tyrosine kinase inhibitors
B. microinjection into cells of nonhydrolyzable GTP analogues
C. exposure of cells to ryanodine
D. exposure of cells to radioactive XFF
E. receptor binding assays
Answer:
The correct answer is - A. exposure of cells to tyrosine kinase inhibitors.
Explanation:
EGF or epidermal growth factor is a protein compound found in human blood responsible for signaling is the member receptor tyrosine kinase family of proteins.
EGF signaling leads to activation or stimulation of various pathways such as Phosphatidylinositol 3-kinase, Ras and or Raf signaling, and or Akt signaling chain of reactions, or STAT pathway. By exposing the cells to the tyrosine kinase inhibitors leads to any of the given pathways then XFF is most likely similar to EGF.

How many subunits are in ribosomes??
Answer:
2 subunits
Explanation:
pls help i need answer asap! The digestive system is a group of organs working together to convert food into energy and basic nutrients that are transported throughout the body. Food passes through a long tube inside the body known as the alimentary canal, made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Once food is chewed, the bolus is moved into the stomach for further digestion. Examine the Interconnections chart and select the body system that is responsible for moving the food from the start to the finish of the digestive system.

B) muscular system
C) integumentary system

4. Explain why the cave appears black.
Answer:
Caves normally apear black. Yes, this is because in a cave there are no natural sunlight or lights in a cave. For example, If your room was all dark it would look black...yes. Same with a cave!

Explanation:
Teniendo en cuenta problemáticas de la biología o de su aprendizaje ,pensar un tema investigar desde el enfoque cualita tivo y otro desde el enfoque cuantitativo
Answer:
Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal
- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio
- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio
Explanation:
Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).

El aparato digestivo de los cocodrilos, adaptado para ingerir una gran variedad de presas es una adaptación de tipo?
La respuesta correcta para esta pregunta abierta es la siguiente
A pesar de que no anexaste opciones o incisos para responder, podemos comentar lo siguiente.
El aparato digestivo de los cocodrilos, adaptado para ingerir una gran variedad de presas es una adaptación de tipo evolutivo morfológico.
Esto significa que a través de los años, la evolución de los cocodrilos los ha llevado a ajustar sus órganos, tal y como es el caso del aparato digestivo.
Esta capacidad de adaptación es una de las tantas maravillas de la naturaleza que permite la adaptación de los organismos de los animales a las necesidades que tienen y los hábitats donde viven, para que puedan sobrevivir cazando los tipos de animales que comen para poder sobrevivir en sus estados naturales.

A married couple plans to have children. The wife has blue eyes (a recessive trait) and her husband has brown eyes (a dominant trait). The husband’s mother had blue eyes. What percentage of their children could possibly have blue eyes?
Answer:
75%
Explanation:
The mom only carries the gene for blue eyes. The dad carries the gene for blue eyes, and the gene for brown eyes. So hypothetically speaking (because Punnet squares are only guesses/predictions) 75% of the kids could have blue eyes
Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so they are less visible to birds than white moths. As a result, black moths are more likely to survive and reproduce, enabling the gene for black coloration to be passed on to the next generation. This increases the frequency of genes for black coloration in the population. Which evolutionary process does this scenario describe
Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.
In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.
