When a rock starts to change color, rust, and break down, it is caused by _____
1wind
2erosion
3mechanical weathering
4chemical weathering
Answer:
the answer is 4
Explanation:
answer each one please!
1. What factors shaped the cliffs of Victoria, Australia over time?
2. How do you know a rock has been or is being weathered?
3. How are weathering and erosion different?
Answer:
Explanation:
1.The powerful surf and the salt of the erratic and moody Southern Ocean started to erode the rugged limestone cliffs along Victoria's Coastline.
2.Animals that burrow underground, such as moles, gophers or even ants, can also cause physical weathering by loosening and breaking apart rocks. Dens and tunnels are signs of this type of weathering. Other animals dig and trample rock on the Earth's surface, causing rock to slowly crumble apart.
3.When the smaller rock pieces (now pebbles, sand or soil) are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.
can someone give me an example on how to write dichotomous keys please
Answer:
"For example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles."

Question: How do different variations lead to evolution of species?
We have learned that mutations and sexual reproduction can lead to variations. Variations that allow an organism to survive in its environment are considered adaptations. The variation with the best adaptation for the environment will survive and reproduce while the others will eventually die off. If the environment changes, a different variation may survive instead. For your final project you will model this in a lab assignment.
Background Information:
Pretend there is an organism on earth called a weezy. There are three variations of weezys: ones with two arms and hands with five fingers (weezy A), ones with one arm and hand with five fingers (weezy B), and ones with one arm and hand with three fingers (weezy C).
Weezys are eaten by smurfs. To protect themselves from smurfs, weezy's build towers out of rocks and climb up to the top of them. Because smurfs can’t climb, the weezys are safe if they manage to get to the top. However, weezys must build their towers quickly because smurfs are extremely fast. The ones who build their towers quickly enough survive, but the ones that are too slow usually get killed by smurfs.
In this activity, you will simulate the three variations of weezys in a population. You will measure how long it takes you to build the tower while pretending to be each type of weezy. You will do three trials for each weezy. As you are doing the activity, complete the data table below. When you are finished, answer the questions that follow.

What is litmus paper? How is it used to determine if a compound is an acid or base?
Answer:
Litmus paper is a tool used to test whether a substance is an acid or base. When a substance is dissolved in water, the resulting solution causes the litmus paper to change color. The acidity or alkalinity of a solution is determined by the concentration of hydrogen ions, or power of hydrogen, expressed as a pH value.
(I think this is right I'm not totally sure.)
What are some factors that affect an element’s reactivity?
Answer:
Four major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons). Metal reactivity relates to ability to lose electrons (oxidize), form basic hydroxides, form ionic compounds with non-metals.

describe the cellular evidence that both plant and animal cells obtain energy through cellular respiration.
Answer:
Explanation:
The glucose required for cellular respiration is produced by plants. Plants go through a process known as photosynthesis. Photosynthesis can be thought of as the opposite process of cellular respiration. Through two processes known as the light reactions and the dark reactions, plants have the ability to absorb and utilize the energy in sunlight. This energy is then converted along with water and carbon dioxide from the atmosphere into glucose and oxygen. Since this is the opposite process of cellular respiration, plants and animals are said to have a symbiotic relationship. This means that plants and animals live together and benefit from each other.

Explanation:
The rate of photosynthesis can be determined by measuring the rate that reactants are used up by a plant or by measuring the rate that products of photosynthesis are produced by a plant. How would placing a plant in a dark room for 24 hours affect the rate of photosynthesis?
A. The rate of photosynthesis would increase and the plant would take in more water.
B. The rate of photosynthesis would decrease and the plant would produce more sugar.
C. The rate of photosynthesis would increase and the plant would produce more oxygen.
D. The rate of photosynthesis would decrease and the plant would take in less carbon dioxide.
Answer:
The answer is D.
The photosynthetic reaction produces oxygen and sugar. When a plant is placed in the dark then the rate of photosynthesis decreases due to less intake of carbon dioxide, Thus, option D is correct.
What is photosynthesis?Photosynthesis has been said a reaction that uses light energy to form chemicals like glucose and carbon dioxide. The rate of photosynthesis is determined by the product formation from the reactants consumed.
Light is a factor that determines the rate of photosynthesis as solar energy is used to split the water molecule and carbon dioxide to produce oxygen and sugar molecules.
The concentration of carbon dioxide and sunlight are rate-determining limiting factors. Less amount of carbon dioxide will be available for plants to intake and hence less reactant will be produced.
Therefore, option D. less carbon dioxide will be present in the room.
