4. What factors contribute to a random distribution pattern? Why do animals
not maintain this distribution pattern year round?
1
Answer:
Random distribution may result when resources are equally distributed and are not scarce. As breeding brings individuals together, random distribution is not maintained year round.
When resources are readily available and evenly distributed, random distribution may occur. The random dispersion of individuals is not maintained year-round, since breeding brings people together.
What contribute random distribution pattern in animals?In environments with stable resources and environmental circumstances, random dispersion typically occurs. This pattern of dispersion is unique in that there are no substantial social contacts between species.
On land and in the water, animals are not equally dispersed. Climate zones or in all the confinements is known as Continuous Distribution, and such species of animals are known as Eurytopic Animals.
They are constrained to certain locations by a number of criteria such as food, shelter, and climate.
Therefore, The absence of any significant social interactions between species is what distinguishes this pattern of dispersion.

All of the following processes are the ones that lead directly to the formation of sedimentary rock EXCEPT-
deposition of rock fragments.
O
freezing of water in cracks in rock.
o
melting of rock deep underground.
movement of wind that carries earth material.
Answer:
melting of rock deep underground.
Explanation:
The melting of rocks deep underground does not produce sedimentary rocks. Most igneous rocks are produced by this process.
When molten rocks underground called magma is solidified in the subsurface, it results into the formation of igneous bodies.
Sedimentary rocks forms by the accumulation of sediments. Inside the basin where the sediments are deposited, they are compacted, cemented and lithified. Chemical and physical weathering of rocks produces sediments.why does the fire snake weight less than it was when it was on fire
Answer:
When Zoe weighs the ingredients (sugar and baking soda), it weighs 25 grams in total. When she weighs the “snake” it weighs 23 grams. This is because some carbon dioxide gas produced during the chemical reaction escapes into the air.
What conclusion can you draw from the information shown in the graph?
O A. Global temperatures are increasing due to human activity.
B. Earth is currently experiencing a period of global warming.
O C. Temperature is the only aspect of climate that is changing.
O D. Global temperatures are increasing due to natural causes.
Answer:
The correct option is;
B. Earth is currently experiencing a period of global warming
Explanation:
From the graph, we have;
1) From 1880 to 1900 the temperature anomaly (°C) averages a few degrees below the average surface temperature
2) The decrease below the average surface temperature is larger from 1900 to 1920
3) The surface temperature rises more steadily from below average to a little above average from 1920 to 1940
4) Between 1940 to 1980, the temperature hovers around the average surface temperature
5) The Earth's surface temperature is more or less steadily increasing from 1960 to present
Therefore, the Earth is experiencing a period of global warming

6. How does the speaker know that the lump of metal she is holding is an asteroid?
- The speaker knows that the lump of metal she is holding is an asteroid because the patterns formed inside the metal. She explains that the rock is older than the earth and that it is an asteroid. This is due to the patterns formed inside it. These patterns show that it contains metallic crystals that cannot be formed on earth, but instead in space where temperatures mean that molten metal takes billions of years to cool. The scientists also use representative sampling. This is done when they deal with such large quantities of objects for estimating.
7. How does the speaker “hunt” asteroids? Describe how teams of scientists collect data about asteroids.
- The speaker “hunts” for asteroids by attempting to search for them for scientific use. She analyzes how long ago these rocks were coming across the earth and how many are in the universe. She also is classifying them by color and shape. Some of the objects can be classified into one or more categories and this could lead to disagreements on where they should or should not be listed. Also, the objects can be difficult to see properly.

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combination is
Answer:
The equivalent resistance of the combination is R/100
Explanation:
Electric Resistance
The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.
Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:
[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]
If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:
[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}...+\frac{1}{R/10}[/tex]
This sum is repeated 10 times. Operating each term:
[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]
All the terms have the same denominator, thus:
[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]
Taking the reciprocals:
[tex]R_e=R/100[/tex]
The equivalent resistance of the combination is R/100

Which diagram has a greater gravitational force
Answer:
2
Explanation:
Due to the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn together by a stronger gravitational attraction. As a result, the gravitational pull between two objects grows as their respective masses rise.
What mass has a greater gravitational force?Since the gravitational force is exactly proportional to the mass of both interacting objects, heavier items will be attracted by stronger gravitational forces. Therefore, the gravitational attraction between two objects grows as their respective masses do as well.
The attraction created by gravity is between masses. The gravitational force, commonly known as the gravity force, increases with the size of the masses. With an increase in the distance between masses, the gravitational pull rapidly lessens.
Therefore, second have greater gravitational force.

12. What is the photoelectric effect, and what experimental evidence led scientists
to discover it? Does this support the wave or particle theory of light? Why?
Answer:
Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
Explanation:
The effect is often defined as the ejection of electrons from a metal plate when light falls on it. In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the material may be a solid, liquid, or gas; and the released particles may be ions (electrically charged atoms or molecules) as well as electrons. The phenomenon was fundamentally significant in the development of modern physics because of the puzzling questions it raised about the nature of light—particle versus wavelike behaviour—that were finally resolved by Albert Einstein in 1905. The effect remains important for research in areas from materials science to astrophysics, as well as forming the basis for a variety of useful devices.
The emission of electrons from the surface of a metal by the action of light is called photoelectric effect. This phenomenon indicates the behavior of light as particles called photons.
What is photoelectric effect ?The phenomenon of ejection of electrons from the surface of a metal when light of a suitable frequency falls on it is called photoelectric effect. Upon striking the surface of metals , light can set up an electric current which current which corresponds to the flow of electrons. This phenomenon is discovered by Einstein
For instance, visible light can cause ejection of electrons from the surface of metal like cesium which has low ionization enthalpy. This phenomenon is related to the observation that if light is considered as particles.
The particles of light is then called as photoelectrons or photons. Photoelectric effect find application in photoelectric cells used in colorimetry, spectrophotometers etc.
