A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
Answers
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.
Hope this make sense!

what will happen to the concentrations of ATP,NADPH, and sugar when you add paraquat
Answers
Answer:
Increase ATP
Decrease NADPH
Decrease Sugar
Concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.
The concentrations of ATP,NADPH, and sugar decreases when you add paraquat because paraquat is a toxic chemical which blocks the activity of respiration in plants leading death of those plants. Paraquat inhibits the ATPase activity which is responsible for the production of ATP.
So due to no cellular respiration no ATP is produced. Paraquat (PQ) also inhibit photosynthesis so no glucose as well as NADPH is produced so we can conclude that concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.

What is deforestation?Deforestation refers to the loss of forest area worldwide to other uses such as agricultural land, urbanization and mining activities. Deforestation, greatly accelerated by human activities since the 1960s, has adversely affected natural ecosystems, biodiversity and climate.
Several factors, both human and natural, cause deforestation. Natural factors include natural forest fires and diseases caused by parasites that can lead to deforestation. Nevertheless, human activities are one of the main causes of global deforestation.

Answers
Answer:
1. binary fission
2.s phase
3.cytokinesis
4 spindle
5.exit from cell cycle
Cell cycle is essential for the cell to divide and grow. The correct answers are 1. Binary fission, 2. S-phase, 3. Cytokinesis, 4. Spindle fibers, 5. Exits from the cell cycle.
1. Binary fission: The parent cell divides into two brand-new daughter cells. The genetic material is split and duplicated into two pieces. Here, the DNA of each daughter cell is duplicated.
2. S-phase: DNA replication and a large portion of DNA repair activities take place in cells during the S phase, which is situated between the G1 and G2 phases of the cell cycle.
3. A cell splits into two daughter cells by physically dividing its cytoplasm through a process called cytokinesis.
4. Spindle fibers: When a cell divides during mitosis and meiosis, spindle fibers are the filaments that make up the mitotic spindle. During nuclear division, they play a major role in transporting and sorting the chromosomes.
5. G0 phase: G0 phase cells do not actively prepare to divide. When cells leave the cell cycle, they enter a quiescent (inactive) state. Some cells briefly enter G0 before the start of G1 is signaled by an outside source.
Therefore, the correct answer is c) binary fission, b) S-phase, c)cytokinesis, d) spindle fibers and e) exit from cell cycle.

What canwe do to decrease our disruption of the nitrogen Cycle?
Answers
Answer:
We can use less pollutants.
Explanation:
Gracias a una investigación internacional se ha averiguado que las actividades humanas causan estragos en los bosques tropicales al alterar el ciclo de nitrógeno normal. Los descubrimientos, publicados en Science, proporcionaron las primeras pruebas de efectos a largo plazo por contaminación de nitrógeno en árboles tropicales. Los científicos, de Austria, Canadá, Alemania y Panamá, trabajaron en dos emplazamientos remotos del Observatorio Terrestre Global del Instituto Smithsonian en Panamá y Tailandia. «La contaminación atmosférica fertiliza los bosques con uno de los nutrientes más importantes para el crecimiento», afirmó S. Joseph Wright del Instituto Smithsonian de Investigación Tropical en Panamá. «Comparamos el nitrógeno que contenían hojas de especímenes secos recogidas en 1968 con el de muestras de hojas de 2007. La concentración de nitrógeno foliar y la proporción de isótopos de nitrógeno tanto pesados como ligeros ha aumentado en los últimos 40 años del mismo modo a como lo hicieron en un experimento anterior en el que se abonó el suelo del bosque. » El nitrógeno se origina en el interior de las estrellas gracias a temperatura y presión elevadas. En condiciones normales es incoloro, insípido e inodoro, y poco propenso a reaccionar con otras sustancias. En la atmósfera flota más del 75% del nitrógeno, que además es un componente esencial de las proteínas. Uno de los cambios que «activan» el nitrógeno viene producido por ciertas bacterias colonizadoras de raíces vegetales que extraen nitrógeno de la atmósfera y lo que significa o fijan en una forma útil para el crecimiento vegetal. Cuando las bacterias ya no necesitan el nitrógeno la planta lo absorbe, para luego pasar a los animales. La fijación del nitrógeno se define mediante el proceso de Haber, que convierte el proceso de nitrógeno gaseoso en amoníaco, un ingrediente común en los abonos. La fijación de nitrógeno por medios artificiales ha aumentado la cantidad de emisiones de nitrógeno reactivo en un 100%. Según los investigadores, el nitrógeno presenta dos formas o isótopos, átomos con la misma
