(2 pts) Describe the process in which an ecosystem moves from a pioneer species to a climax community.
Answer:
As an ecological community develops, it goes through a series of stages called ecological succession. The enduring community, in which specific and environmental changes are minimized, is called the climax community.
Explanation:
Succession is a process that generally begins after a significant alteration or extinction of an existing community. During succession, a community begins from a point where pioneer species colonize a new area. Pioneer species actively work to provide nutrients to soils and thus allow life to begin to form in them.During this time, there is widespread growth of these fast-growing species. If this new development is in an area that has never been settled before, this is called primary succession. If colonization occurs where an area has been so severely disturbed that the original community no longer exists, this is called secondary succession. Primary succession begins with the establishment of pioneer species such as lichens and mosses. These change the physico-chemical characteristics of the substrate. Later, small plants such as grasses, shrubs and then trees arrive, until culminating in a climax community dominated by certain species. The equilibrium that characterizes the climax community can be altered by climatic, ecological and evolutionary factors.
Which describes organisms going into deep sleep for the winter?
A. Birds migrating
B. Animals hibernating
C. Trees losing their leaves
D. Insects during metamorphosis
Answer:
Animals hibernating is the answer
Explanation:
Hiberntion is when animals sleep for months in the cold winter
When animals hibernate, it is usually in the winter. They store food with them for when they wake up.
An example is squirrels which store acorns near them when they go to hibernate
Birds migrating is usually to lay eggs
Trees losing leaves is usually so that they can store their precious nutrients like glucose
Insects during metamorphosis is when they change form, eg from a caterpillar to a butterfly

Changes in _____ result in the formation of metamorphic rocks.
a. Weathering
b. Sedimentation
c. BothAandB
d. Temperature and Pressure
Answer:
During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids.

Why should organisms that produce more offspring have a more likely chance of survival?
Answer:Organisms must struggle to get what they need to survive, competing against other organisms that want the same things they do.
Explanation:
Answer:
I will try to put this in the simplest terms I can:
If you think about it, organisms actually do not live that long. There are multiple cause and effect reasons, such as low resources, no food, extinction, and so on. Thus, organisms must produce offspring to keep their "family line" consistent.

5. The theory of common descent states that all modern organisms
*
A. Can change in response to environmental change
B. Are descended from a single ancestral species
C. Can be arranged in a linear order from "Least Evolved" to “Most Evolved”
D. Have not changed over time
Answer:
B
Explanation:
All living beings are in fact descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth, according to modern evolutionary biology. Common descent is an effect of speciation, in which multiple species derive from a single ancestral population.
What process can change all three rock types in a new metamorphic rock?
Answer:
The three main rock types are igneous, metamorphic, and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

The process of obtaining food by __________________ is called phagocytosis.
Answer the following questions:
⦁ What is the purpose/function of the Respiratory System?
⦁ What is the purpose of the tiny hairs called cilia in your nose?
⦁ What are the purposes of the pharynx?
⦁ What is the purpose of the epiglottis?
⦁ How is the respiratory system linked to the cardiovascular system
Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

1. What causes the inside of the cell to be more negative compared to the outside of the cell? Resting Potential, Action Potential
Answer:
Resting potential
Explanation:
This is because , the resting potential is negative in side of the cell because it has more negative charge inside than outside due to accumulation of alot of sodium and potassium ions. when an axon is at rest in the cell, the anions produce negative charge, the sodium pumps eject sodium out of the cell and potassium is injected in, and the sodium gates and potassium gates are all closed.
