Quick question. I am trying to cite my sources for my biology research project and the website that I used is a rare disease informational center with different topics. For example there is a summary section, a symptoms section etc.... I need to cite my sources however each section has a different publication date because they don’t update the entire article at once. I am currently trying to use an in text citation for the summary because I used a quote from the summary so do I just use the summary publication? But I did use other sections of this website for other parts of my essay so when it comes time to making my bibliography what do I do
Answer:
For your bibliography, you need to put the website but also put the sections you got your examples from. Also, don't forget to put the person who published the summary down as well. Hope this helped

Describe the similarities and differences between plant and animal cells
Answer:
Plant cells have a cell wall and a cell membrane.
In plants, the cell wall surrounds the cell membrane.
Animal cells have a cell membrane but no cell wall.
Plant cells have cytoplasm.
Both have a nucleus.

In the experiment, "Do white cats eat more than black cats?" the independent variable would be:
the color of the cat.
how much each cat weighs.
how much food each cat eats.
the temperature of the food.
In the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.
What is an Independent variable?An independent variable may be defined as a type of variable that significantly and effectively stands alone and isn't changed by the other variables you are trying to measure. The independent variable is the cause. Its value is independent of other variables in your study.
According to the context of this question, the color of the cat would not depend on how much food a particular type of cat eats. This will depend on the nature and diet of the cat along with its physiology and pattern. So, the color of the cat would be thought to be the independent variable in the experiment because it does not make any sense in the eating cat.
Therefore, in the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.

What significance does density have for earth?
Answer:
The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.
factors affecting environment and development
Answer:
Environmental factors affecting plant growth and development include light, temperature, water, humidity, and nutrition. At the time of nurturing a tree, it is important to know how these factors could affect the growth and development of a plant. Knowledge about environmental factors helps the owner promotes proper growth.

Is this a true or false question? If so, this statement is true.
Explanation:
Della and Nick drove at constant
speed from town A to town B along
the same road. The distance between the
two towns was 210 km. Nick left
Town A half an hour later than Della
Both of them arrived in Town B at
the same time . Della drove at a
Speed of 60 km/h Find Nick's speed.
Plzz help mee
Answer:
70 km/hr
Explanation:
Distance between town A and B = 210 km
Della's speed = 60 km/hr
Time taken by Della = distance / speed
Time taken by Della = 210 km / 60km/ hr
Time taken by Della = 3.5 hours
Since Nick left half an hour later Than Della ;
Then, Nick's travel time = 3.5 - 0.5 = 3 hours
Nick's average speed = Distance /time
Nick's average speed = 210 / 3 = 70km/hr
how is specialization beneficial for an organism
What is the general relationship between distance from the sun and a planets density?
Answer:
There is no connection between a planet's distance from the Sun and its rate of rotation (spin on its own axis or Planetary Rotation Period). While it is true that, generally speaking, the gas giants have higher rotation rates than the earth like planets closer to the Sun, any correlation is only coincidental.

While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hear them
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
