The sputum (fluid coughed up from the lungs) of many smokers contain cells with mutations in the genes for p53. The smoking-induced mutations appear to be an early signal showing that cancer of the lungs will follow. What is the likely relationship between early p53 mutation and the development of lung cancer

Answers

Answer 1

Answer:

The correct answer would be - mutations in the p53 would prevent abnormal cells from dying by apoptosis.

Explanation:

P53 or tumor protein 53 gene is the gene that produces a protein that controls DNA repair and apoptosis in the cell cycle if there is an error in the DNA or cells growing abnormally therefore known as tumor suppressor gene.

If there is a mutation in this gene will prevent it from performing its function of DNA repair or stimulating apoptosis and then p53 would prevent abnormal cells from dying by apoptosis.

Thus, the mutation in P53 would lead to the growth or development of lung cancer.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.

Answers

Answer:

C

Explanation:

They threaten the other animals. They can take their food, homes, and they don't have natural predators.

Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.

Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.

Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.

The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,

Thus, biodiversity is threatened due to the invasive species.

O A. reflection
O B. refraction
O C. absorption
OD. deletion

Answers

Answer:

B. refraction

Explanation: hope this helps!

The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.

What is Refraction?

Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.

Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.

Therefore, the correct option will be B.

Which part of the carbon cycle occurs when plants, trees, or fossil fuels are burned?
A. Transpiration B. Oxidation C. Photosynthesis D. Combustion

Answers

Answer:

Combustion.

Explanation:

It's just as it sounds, combustion is the process of burning something. In the carbon cycle, combustion occurs whenever any organic living or non-living thing is burned in the proximity of oxygen, afterwards producing carbon dioxide.

Combustion is the part of the carbon cycle which occurs when plants, trees, or fossil fuels are burned. Thus, the correct option is D.

What is Combustion?

Combustion or burning is a high-temperature exothermic redox chemical reaction which occurs between a fuel and an oxidant. The oxidant is usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. This is one of the major reasons of pollution.

Three main types of combustion include rapid combustion, spontaneous combustion, and explosive combustion.

Therefore, the correct option is D.

Why is some amount of air is left inside in your lungs after inhalation

Answers

Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.

So your answer will be Residual volume...

Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D

It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

Which organelle plays an important role during mitosis, helping to move chromosomes around the cell
a

Ос
Od
vacuoles
Golgi bodies
chloroplasts
centrioles

Answers

Answer:

Explanation:

Duplicated centrioles are responsible for moving chromosomes during mitosis.

They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.

It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.

Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.

They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.

Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.

These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.

During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.

At the end in telophase, where nuclear membrane becomes visible it disappears.

In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.

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%.
