Si la filosofia es un saber acerca de las cosas desde un punto de vista universal, entonces dificilmente sea ciencia
Explanation:
Esta afirmación es correcta, porque si bien la ciencia se deriva de la filosofía, la filosofía es la necesidad humana de obtener conocimientos y así desarrollar un pensamiento racional, crítico y diferente al sentido común, y por tanto se conceptualiza como algo más subjetivo, cultural y más amplio que la ciencia. , que se basa en hechos y estudios para respaldar un análisis. A través de la filosofía es posible desarrollar la ciencia, pero son cosas diferentes porque la ciencia está ligada al empirismo y la filosofía es más amplia y comprensiva.

7. A student astronomer went out and took photographs of the Moon that were several days apart.
Images that look like her photographs are shown above. The light part of the Moon appeared to get
smaller over time. Why did this happen?
a
Between the first photograph and the second photograph, the Moon moved farther away
from the sun so less sunlight reached the Moon's surface.
b
Between the first photograph and the second photograph, Earth moved so its shadow was
blocking more of the Moon so the student astronomer was able to see less of it.
с
Between the first photograph and the second photograph, the Moon rotated so that less of
the light-colored rock on the Moon's surface faced Earth.
d
Between the first photograph and the second photograph, the Moon moved so that the
student astronomer was able to see less of the half that faces the sun.

Answer:yh it is b
Explanation:
A student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.
What is the significance of the moon revolution?The changing appearance of the moon over time is due to its changing position in its orbit around the earth, the light part of the moon appeared to shrink over time as the moon moved in its orbit, causing the illuminated part that faces the earth to diminish and the dark phase to appear.
Hence, a student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.

Explanation:
Sewage sludge (biosolids) removed from a municipal wastewater treatment plant is a mixture of organic material and water. Research and explain why the incineration of sewage sludge may require more energy than it produces. Explain why people may be reluctant to use biosolids as a fertilizer for food crops.
Hey love! <3
Answer:
Sewage systems are used all around the world transferring waste to treatment plants where they are filtered and traded in for organic material. If the sluge were to be incinerated it could be repurposed, however the gas used to burn the sewage waste comes from condensing saturated fuel oil and requires 195 SCM of natural gas to successfully complete the chemical transfer. That's a lot of energy, and the natural process costs plenty more then what you're getting in returns. Through the process toxins can develop inside of the incinerated waste which could poison crops and animals, studies also show the process can release carbon monoxide into the air. To conclude it's called sewage waste for a reason, what goes down should stay down instead of putting what we eat and inhale at stake.
Hope this helps out! (ﾟヮﾟ) Sincerely, Kelsey from Brainly.

The incineration of sewage sludge may require more energy than it produces because of the high cost of energy.
Municipal wastewater treatment plants are estimated to consume more terawatt hours per year of electricity, which equates to about billions in annual electric costs. That's a lot of energy, and the results show that wastewater sludge able to produced up to 44.82 ml biogas/kg of sludgePeople may be reluctant to use bio solids as a fertilizer for food crops.
because:-
One health risk with the land application of bio solids is the potential exposure to pathogens (disease causing organisms)One of the risk is that the bio solids may contain chemicals that are directly toxic in small concentrations or doses.What is sewage sludge?Sewage sludge is a product of wastewater treatment.

Which of the following is not an appropriate unit for momentum?
A. g • cm/min
B. g • m/S
C. km • m/S
D. kg • m/hr
Answer:
Option C us correct.
km • m/S
Explanation:
This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.
From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.

Given RRYY x Rryy, what will the parents be? (no links please)
I'm guessing the genotypes given (RRYY x Rryy) are the offspring (if this isn't the case this answer may be wrong)
RRYY has both dominant alleles. So we can safely say that the parents are both RRYY.
For Rryy :
Rr is heterozygous (the alleles are not the same), so the parents could be:
RR x rr
RR x Rr
Rr x Rr
(if you do a small punnet square, you can double check these!)
Since yy has both recessive alleles, the parent is yy as well.

Which of the following is most likely to contribute to density-dependent regulation of populations? Group of answer choices Individuals voluntarily stop mating so that overcrowding does not occur. Density-independent factors lead to fewer births and increased mortality. The incoming energy decreases in populations experiencing a high rate of increase. Density-dependent factors lead to fewer births and increased mortality.
Answer:
Density-dependent factors lead to fewer births and increased mortality.
Explanation:
The carrying capacity can be defined as the maximum population size an environment can support. Density-dependent limiting factors produce a logistic growth pattern (S curve) in the population until it reaches its carrying capacity, thereby decreasing the birth rate and increasing the mortality rate in the population. Some important density-dependent limiting factors able to control the size of the population are competition (intraspecific competition), predation and diseases.

Each gland consists of two parts: an inner medulla, which produces epinephrine and norepinephrine (adrenaline and noradrenaline), and an outer cortex, which produces steroid hormones.
The structures that are part of the cortisol pathway are the hypothalamus and liver.
Cortisol is a glucocorticoid in the brain with the function of operation of Gluconeogenesis and stress. The pathway of cortisol in the body is termed as cortisol pathway.
What structures are in the Cortisol pathway?The cortisol pathway is started with the release from the brain, targeting the hypothalamus. The release of epinephrine and nor-epinephrine is controlled with the cortisol release.
The release of the hormones targets the pituitary and adrenal gland and controls the release of stress hormones.
The gluconeogenesis process is controlled by the cortisol hormone. The process takes place in the liver.
Thus, the structures that are part of the cortisol pathway are the hypothalamus and liver.

Which of the following statements is true?
Fusion reactions split hydrogen nuclei apart.
Fission reactions release more energy than fusion reactions.
Nuclear power plants change electricity into nuclear energy.
U-235 is an isotope of uranium.
Answer:
Fission occurs when a neutron slams into a larger atom, forcing it to excite and spilt into two smaller atoms—also known as fission products. Additional neutrons are also released that can initiate a chain reaction.
When each atom splits, a tremendous amount of energy is released.
Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control.
The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.
Explanation:none

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.
