The role of pioneer species in primary succession is to produce the soil.
WHAT IS PRIMARY SUCCESSION?Primary succession is the type of succession in which there is no previous form of life in a habitat.
Pioneer species are those species that first colonize an area. In primary succession, pioneer species like lichen colonize bare rocks i.e. no soil.
Therefore, role of pioneer species in primary succession is to produce the soil.

Which of the following is a result of a large forest fire?
Wildlife populations will increase in the area .
Wildlife populations will decrease in the area.
New plant growth will decrease for many years.
All new organisms will populate the area.
Answer:
u already know the answer
Explanation:the answer
When their population of the wildlife should be increased in the area so this result in the largest forest fire.
What is population:
Population represent the no of individuals for the specific species in the area. The animal & plant population depend upon various things for survival purpose. here the limited factors should be food, water, etc. So in the case when there is the population of the wildlife so it does not reduce the area, nor their is any decrement of the new plant growth. Also, there is no new organism that populated the area.
Therefore, When their population of the wildlife should be increased in the area so this result in the largest forest fire.

In a carbon dioxide molecule (O=C=O), which statement is true of the electrons?
A) The electrons are being shared between the carbon and oxygen atoms.
B) The carbon has gained electrons, giving it a negative charge.
C) The electrons are involved in ionic bonding.
D) The oxygens have gained electrons, giving them a negative charge.
Answer: Option A.
The electrons are being shared between the carbon and oxygen atoms.
Explanation:The electrons are being shared between the carbon and oxygen atoms because each oxygen share four electrons with the central carbon, therefore carbon atoms have 8 electrons that is shared with oxygen. The oxygen have two shared pairs in double bond and two lone pairs in non bonding. Carbon and oxygen form covalent bond. This satisfies the octet rule because the electrons are shared in both oxygen and carbon octet.
In a carbon dioxide molecule (O=C=O),

Where in an equation for photosynthesis does oxygen belong?
on the left side, because it is a product
on the right side, because it is a product
on the right side, because it is a reactant
on the left side, because it is a reactant
Answer:
On the right side, because it is a product.
Explanation:
6 CO2 + 6 H2O + light -----> C6 H12O2 + 6 O2.
In photosynthesis, the oxygen belongs to the right side of the reaction, because it is a product. Thus, the correct option is B.
What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some algae prepare their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.
The chemical reaction of the photosynthesis is as follows:
[tex]6CO_2 + 12H_2O[/tex] + sunlight → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex].
Therefore, in photosynthesis, the oxygen belongs to the right side of the reaction, because it is a product. Thus, the correct option is B.

How large is the visible light portion of the Electromagnetic Spectrum?
Answer:
The human eye can detect up to 700 nanometers but the range adjacent to the visible spectrum is called the near infrared and the longer wavelength part is called far infrared. The region just below the visible in wavelength is called the near ultraviolet. Hence the visible part of electromagnetic spectrum lies in between ultraviolet and infrared.

Where would muscle B in the image set most likely be found
A. Lining of a tendon
B. Lining of a thigh bone
C. Lining of the ventricle of the heart
D. Lining of the esophagus
Muscle A - Smooth muscle
Muscle B - Skeletal muscle
Muscle C - Cardiac muscle
Muscle B which is a skeletal muscle can be found in LINING OF A TENDON.(option A)
The Skeletal muscle forms those muscles that move the bones of the skeleton,they are straited because they have straitions that is strips which can be seen on examination using a microscope,they are voluntary and also under conscious control.they are roughly cylindrical in shape and lies parallel to one another with a distinctive appearance that is banded and consists of alternating dark and light strips.
Although most skeletal muscles move bones,the diaphragm is a type that is made from the type of muscle,it is made to accommodate a degree of voluntary control in breathing.
The fibre cells in skeletal muscle are cylindrical in shape and they contain several nuclei that can be up to 35cm long. Contraction of the Skeletal muscle is stimulated by motor nerve impulses that originates in the brain or spinal cord and ends at the neuromuscular junction.
When Individual muscles cells in a muscle shorten,they pull on the connective tissue framework which runs through the the whole muscle and the muscle develops a degree of tension/tone.
Skeletal muscles are found between bones in the body and they use the tendons to connect to bones.

Which two cycles are linked by the production and utilization of carbon dioxide? Where do these cycles occur?
Answer: The Calvin Cycle in Photosynthesis and The Krebs Cycle in Cellular Respiration. The Calvin Cycle occurs in chloroplasts and The Krebs Cycle occurs in the Mitochondria.
Explanation:
The two cycles that are associated by the utilization and production of carbon dioxide are cellular respiration and photosynthesis. These two processes takes place in the mitochondria and chloroplasts.
What is photosynthesis and cellular respiration?The process by which green plants and some of the organisms utilize light from the sun to produce foods from water and carbon dioxide is known as photosynthesis. The process generally takes place in the chloroplasts of the cell. In the process, energy is captured and oxygen is released.
The set of metabolic reactions and procedures, which occur in the cells of organisms to transform chemical energy from the molecules of oxygen or nutrients into ATP, and then discharge waste products like water and carbon dioxide. The process takes place within the mitochondria.
Thus, in cellular respiration production of carbon dioxide takes place, while in the process of photosynthesis carbon dioxide is used to produce food.

What is the relationship between the number of wolves and the number
of deer?
Answer:
if the number of wolves increase the number of deer decrease
Explanation:
because deers are prey and wolves are predators
Wolves and deer show a prey-predator relationship. This indicates that as the number of wolves increases, the number of deer decreases and if the number of deer increases it means that the number of wolves has been decreased.
What is Prey-predator relationship?Prey-predator relationship is a type of association seen in the environment. In this relationship, one species feeds upon the other species. The prey species is the animal being fed on, and the predator is the animal who feeds. The predator prey relationship develops over time.
As the prey population increases, there is more food for the predators. So, after a small time, the predator population increases as well. This number keeps on increasing till sufficient food is available. As the number of predators keeps on increasing, more prey are captured. This results in the decrease in prey population.
The relationship between the wolf and its prey, deer is very complex. Wolves population keep deer moving, which provides an ecological benefit for the health of the deer and plant species which are damaged from over-browsing. This keeps the number of species constant.

Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic processes. To function properly, the organelles must move substances across their membranes.
what is a feature shared by mitochondria and the endoplasmic reticulum that increases the efficiency of their basic functions?
Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
