Answer:
The statement which best describes about ecological succession is that the one which states that It is a series of 'rapid changes' in an ecosystem.
Ecological succession is caused by human intervention. Therefore, the correct statement is option B.
What is ecological succession?Ecological succession is a natural process that takes place after an ecosystem is disturbed by something like a fire, flood, or human activity. It is an anticipated example of changes in the species synthesis and local area design of an environment over the long haul.
Ecological succession is a process in which the ecosystem's physical and biological characteristics undergo a series of gradual shifts over many years or even centuries.
From the pioneer stage to the climax stage, where the ecosystem reaches a relatively stable state, ecological succession involves a series of stages. Different species of plants and animals replace one another during ecological succession, resulting in shifts in the ecosystem's physical and biological conditions.
Therefore, ecological succession is caused due to human intervention where the ecosystem is disturbed by a fire, flood, or human activity.

On May 18,1980, Mount St. Helens in the state of Washington erupted with the force of a hydrogen bomb. The volcano had been dormant for over 120 years, but now 57 people were dead; forests and lakes were totally destroyed, including nearby Spirit Lake, which became a mud hole. The blast leveled trees in areas over 10 miles from the crater and ash deposits suffocated life on the mountain. However, within weeks, mammals that had taken shelter underground started to appear in the area, and now, over thirty years later, many areas of the mountain are colonized with a large variety of plant and animal life. How does an area move from a sterile, barren wilderness to one full of life
Answer:
The correct answer is - Ecological Succession.
Explanation:
Ecological succession is a change in the species or biodiversity over time by the increase in the vegetation or growth of the community. This takes place after a natural disaster or any event that causes nudation or complete removal of species or comunities from an area such as volcanic eruption.
It starts with nudation then invaded with primary successors and then ecological conditions lead to invading more species and the third stage would be competition and interaction between a component of the species and vegetation then stable.

Rain cannot occur until ____?
A. the air becomes saturated with water vapor
B. the water vapor exceeds an absolute humidity of 80 ppm
C. a warm front meets a cold front
D. clouds reach an altitude of 1000 ft
Answer:
A. the air becomes saturated with water vapor
Explanation:
The saturated water vapor air forms clouds ( nimbus clouds ) which hold that vapour at a low pressure
Answer:
A. The air becomes saturated with water vapor
Explanation:
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew point is the temperature at which condensation happens.
What is affected by natural selection?
Answer:
variation
Explanation:
Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

What would most likely happen if there were no condensation stage in the water cycle
Answer:
No precipitation.
Explanation:
if there were no condensation stage in the water cycle then there will be no precipitation and as a result the water cycle will stop. Condensation is the change of water from its gaseous state or water vapor into liquid water. This condensation process occurs in the upper atmosphere where the temperature is lower as compared to the earth surface so the water vapors turn into liquid state and will fall from the sky in the form of rainfall and snowfall so we can say that no condensation will leads to no precipitation.
A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 125.6 units of niacin and 5,400 units of retinol. She uses two types of commercial pellet food. Food A contains 0.86 units of niacin and 30 units of retinol per gram. Food B contains 0.66 units of niacin and 40 units of retinol per gram. How many grams of each food does she feed this group of rats each day
Answer:
- 100 grams of food A (x)
- 60 grams of food B (y)
Explanation:
According to this question, the group of laboratory rats are being fed a daily diet of:
- 125.6 units of niacin and 5,400 units of retinol
Let x represent the number of grams needed for food A.
Let y represent the number of grams needed for food B.
This means that:
Food A: Niacin = 0.86x, Retinol = 30x
Food B: Niacin = 0.66y, Retinol = 40y
Since there are 125.6 units of niacin fed to the rats in total, then;
0.86x (A) + 0.66y (B) = 125.6
Since there are 5400 units of retinol fed to the rats in total, then;
30x (A) + 40y (B) = 5400
Solving these two equations simultaneously using elimination method:
0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)
30x (A) + 40y (B) = 5400 ............ (eqn 2)
Multiply eqn 1 by 30 and eqn 2 by 0.86
30 × 0.86x + 0.66y = 125.6
0.86 × 30x + 40y = 5400
25.8x + 19.8y = 3768 ............ (eqn 3)
25.8x + 34.4y = 4644 ........... (eqn 4)
Subtract eqn 3 from eqn 4
14.6y = 876
Divide both sides by 14.6
y = 876/14.6
y = 60
Substitute value for y (60) into eqn 2
30x + 40y = 5400
30x + 40(60) = 5400
30x + 2400 = 5400
30x = 5400 - 2400
30x = 3000
x = 3000/30
x = 100
Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
surrounded by water.
Answer:
The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.
It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.

2. Optic chiasma
3. Corpora quadrigemina
4. Cerebellum
5. Thalamus
6. Medulla oblangata
7. Corpus Collosum
8. Fornix
9. Cerebral aqueduct
10. Midbrain
Explanation:
The hypothalamus is a small central region of the brain that regulates body temperature by responding to both internal and external stimuli and also produces the antidiuretic hormone (ADH) in order to trigger the reabsorption of water in the kidneys. The optic chiasma is a special sensory structure located along the visual pathway, directly in front of the hypothalamus, which is crucial to vision. The corpora quadrigemina, also known as quadruple bodies, are reflex centers located in the mesencephalon (midbrain) that regulate the position of the head and eyes in response to somatic stimuli. The cerebellum is a part of the brain located behind the top part of the brain stem which is involved in motor movement regulation and balance control. The thalamus (massa intermedia) is a paired gray matter structure found near the center of the brain that plays vital roles associated with sensory and motor functions of the brain. The medulla oblangata (medulla) is a structure located at the base of the brain involved in the regulation of sensory, motor, and mental functions (e.g., breathing, pain modulation, etc). The corpus callosum (the callosal commissure) is a bundle of nerve fibers that connects the two hemispheres of the brain. The fornix (agenesis of the corpus callosum) is a large interhemispheric commissure that connects neurons in the right and left hemispheres. The cerebral aqueduct (aqueduct of Sylvius) is a narrow channel that connects the third and fourth ventricles, thus allowing the cerebrospinal fluid to flow between the ventricles. Finally, the midbrain o 'mesencephalon' is a small region located in between the forebrain and hindbrain, which is involved in auditory and visual processing, eye movement and coordination.
