Answer:
As APC is indicated as a tumor suppressor, lack of APC would lead to tumor development in the mutated mice.
Explanation:
The wnt signaling pathway plays an important role in controlling stem cell proliferation. Stem cells are present in the gut and other locations where they are required to be replenished after short intervals. In the gut, the gut epithelial is exposed to a very tough environment i.e. digestive acids. Thus it is replenished where the new stem cells originate from underlying stem cells.
Axin binding is the major component of this process. However, the unaffected axin leads to binding with a component termed TCF. TCF4 genes include cell cycle factors (such as myc) that encourage cell regeneration.
When the ligand is absent and APC is present, the axin bound with APC to form a team that directs and controls the cell regeneration.
Thus, if APC is not expressed in a cell, beta-catenin in the axin is available to bind to TCF inducing wnt response element genes that stimulate cell proliferation.
The result in tissue level is an enhanced rate of cell growth which leads to tumor.

Fresh steak is said to have both negative and positive redox potential. Discuss how the redox potential affects the microbial ecology of the food
Answer:
Increases redox potential decreases microbial growth inside food.
Explanation:
The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.

photosynthesis
(3) Guard cells change the size of leaf openings, regulating the exchange of gases.
(4) Guard cells release oxygen from the leaf at night.
Antibody molecules and receptor molecules
Answer:
The first one is your answer
Chloroplasts take in more nitrogen, which increases the rate of photosynthesis illustrates feedback mechanisms in plants.
feedback mechanism is a form of system regulation that occur in living organs which help to return or restore the body to it's original normal internal condition for sustainability of living. It is also called homeostasis.
Chloroplasts take in more nitrogen, which increases the rate of photosynthesis illustrates feedback mechanisms in plants because nitrogen helps to increase the concentration of chlorophyll which is the green pigment house in chloroplast that aid the increase of photosynthesis rate in plants.
Therefore,Chloroplasts take in more nitrogen, which increases the rate of photosynthesis illustrates feedback mechanisms in plants.

All of these events are characteristic of an El Niño event except:
A- the Midwestern United States experiences more rainfall than usual.
B- the usual South America-to-Southeast Asia winds ease.
C- South Africa, Japan, and Canada experience warmer than usual weather.
D- ocean surface temperatures are lower than usual.
E- storms form off the coast of California.
Answer:
B- the usual South America-to-Southeast Asia winds ease.
Explanation:
The usual South America-to-Southeast Asia winds did not blow from west to east because of El Nino event. In normal condition, the winds blow easterly from South America-to-Southeast Asia which means from west to the east direction but due to El Nino event, the wind blows is reversed which causes the blowing of winds towards westerlies which means from east to the west direction so the usual blowing of winds from South America-to-Southeast Asia did not occur.

Chemical reactions of fossil fuels
Difference between biomass and fossil fuels
Comparing biomass with other renewable
energy sources
Making energy choices locally
Answer:
CH4 + 2O2 -----> CO2 + 2H2O.
Explanation:
CH4 + 2O2 -----> CO2 + 2H2O is the chemical reaction of burning of fossil fuels. The main difference between biomass and fossil fuels is that biomass is biological material which can be derived from living whereas Fossil fuel such as coal, oil and gas are derived from biological material. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass is renewable just like other renewable energy sources because both can be used again and again. The energy choices locally occurs according to the availability of energy resources in that locality.
If the birth rate and death rate are balanced in a population, how might a population increase in size?
I
Answer:
Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow
Explanation:
Natural increase in a population occurs where Birth rate is greater than death rate. ... Natural decrease occurs when death rate is greater than birth rate. This means that more deaths occur in a population than babies are born so population numbers decline
The population will be doubled by immigration. The correct option is C.
What is immigration?When an animal settles down in a habitat because it has resources nearby or because it is a good fit for them, this is referred to as immigration.
When an animal emigrates, it's because its habitat is no longer perfect for it and it needs to move to a new location with a better habitat.
It is the quantity of members of the same species that have entered the habitat during the time period under examination from outside the habitat.
To immigrate means to move permanently to another country. To migrate is to move, much like wintertime birds. Depending on the viewpoint, one can either migrate, immigrate, or emigrate.
Immigration can increase the size of a population if the birth and death rates are equal.
Thus, the correct option is C.

Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.

Answer:
espero que te sirva
Explanation:
El calentamiento global y el cambio climático tienen coincidencia en la principal
de sus causas, la emisión masiva de los diferentes gases de efecto invernadero o
GEI que retienen el calor dentro de la atmósfera y sobre la superficie terrestre a
través del denominado efecto invernadero.
El efecto invernadero es un proceso natural por el cual se produce la retención
del calor procedente del Sol en la atmósfera terrestre gracias a la capa de GEI que
se encuentra en ella. Estos gases en cantidades normales mantienen la
temperatura del planeta aproximadamente a 33ºC por encima de la que podría
tener si estos no existieran, por lo que el planeta sería demasiado frío para que se
desarrollase vida en él. Sin embargo, actualmente el efecto invernadero se está
volviendo tan intenso a causa de nuestras emisiones que comienza a tener graves
repercusiones en el medio.
El Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC)
concluyó en el Quinto Informe de Evaluación (AR5) de 2013 que la influencia
humana había sido la causa dominante de este calentamiento producido desde la
mitad del siglo XX a través de la emisión de GEI, lo cual es una evidencia cada vez
mayor. Entre los principales gases emitidos se encuentran el vapor de agua, el
dióxido de carbono, el metano y el ozono.
