Which would be the most accurate title for this picture?
a)primary succession after a controlled fire
b)primary succession after a volcanic eruption
c)secondary succession after a controlled fire
d)secondary succession after a volcanic eruption
Primary succession after a volcanic eruption would be the most accurate title for this picture. So, the correct option is B.
What is Primary succession?The process of ecological succession known as primary succession occurs where there was previously no biological community, such as on bare rock, in sand dunes, or after a volcanic eruption. Pioneer species that can colonize bare rock and soil, such as lichens and mosses, typically initiate primary succession by doing so.
As these pioneer species slowly decay and decompose, they add organic matter to the soil and promote colonization by other plants and animals. The primary succession process can take hundreds or even thousands of years to achieve a stable climax community, which is an organism community that is mostly self-sustaining and adapted to its environment.
So, the correct option is B.

Explanation:
Because if the organism is performing cellular respiration, it will be taking in oxygen causing it to decrease, while carbon dioxide will be increasing
Answer:
D.) the organism is performing respiration because the carbon dioxide is increasing and the oxygen is decreasing.
Explanation:
Over time, when an organism, (for example, a cat) is breathing in a confined space for a long amount of time, the air in the space will have more carbon dioxide in it.
This is because as the cat breathes in the oxygen, it is exhaled as carbon dioxide.
Therefore, after a long period of time that cat will have breathed in a lot of the oxygen which is replaced with carbon dioxide.

The sierra Nevada mountains are made from...
A Mafic igneous intrusive rock
B felsic igneous extrusive rock
C felsic igneous intrusive rock
D Mafic igneous extrusive rock
PLEASE HELP ASAPPPP
The Sierra Nevada mountains are made from felsic igneous intrusive rock, specifically granite, which is formed from slow-cooling magma beneath Earth's surface.
Explanation:The Sierra Nevada mountains are composed principally of felsic igneous intrusive rock. This felsic composition is rich in light-colored minerals such as feldspar and quartz, which indicate that the rock is granite in nature. The formation process involves magma cooling slowly beneath the Earth's surface, allowing time for larger crystals to develop, which gives the rock a coarse-grained texture. Therefore, the correct answer to which type of rock the Sierra Nevada mountains are made from is option C: felsic igneous intrusive rock.

Answer:
Plants alternate their generations between sporophyte and gametophyte generations.
Explanation:
Plants life cycle has two generations i. e. Sporophyte and gametophyte. Sporophyte is the first phase of plant life cycle in which spores are produced that are diploid i. e. double number of chromosomes while the second phase is gametophyte in which gametes are produced that are haploid i. e. half number of chromosome. Gametes contains sperm cells and egg cells which fuse together in the process of fertilization.
What are some of the causes that disrupt the natural balance of the ecosystem? ridding the soil of decomposers removing predators by hunting overpopulation of predators breeding hybrid plants removing prey by transplantation
Answer: overpopulation of predators
Explanation: Overpopulation of predators is the correct option. Predators are the organisms which kill other organism so as to obtain them as food. The organism being killed is called as the prey.
If the population of the predators increase this will lead to the extinction of many species of prey. As it is evident that every organism in the ecosystem has a typical role to play. Therefore, it can be said that role of prey will not be performed and this may lead to disturbance in the ecological balance.

He should hold the graduated cylinder in his hand so the surface of the water is at eye level.
II.
He should place the graduated cylinder on a flat surface and bend down so the surface of the water is at eye level.
III.
He should take the reading from the bottom of the curve of the surface of the water.
IV.
He should take the reading from the highest point of the surface of the water.
A.
II and IV only
B.
I and IV only
C.
I and III only
D.
II and III only
To measure the volume of water in a graduated cylinder, follow these steps: place the cylinder on a flat surface and read the volume from the bottom of the curved surface (meniscus).
Explanation:To measure the volume of water in a graduated cylinder, the correct procedures are:
He should place the graduated cylinder on a flat surface to ensure stability and accurate readings.
He should take the reading from the bottom of the curve of the surface of the water (the meniscus).
These procedures help to ensure accurate measurements by minimizing human errors and taking into account the meniscus, which is the curved surface of the liquid in the graduated cylinder.

Cellular respiration involves a reaction between glucose and oxygen to form. A.water.
B. energy.
C. carbon dioxide.
D. all of these.
Answer: D
Explanation: THE PRODUCTS FOR cellular respiration are water CO2 AND energy
Cellular respiration involves a reaction between glucose and oxygen to form water, energy in the form of ATP (Adenosine triphosphate), and carbon dioxide. Thus, the correct option is D.
What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor such as the oxygen atom to produce large amounts of energy, to drive the bulk production of ATP (adenosine triphosphate) in the mitochondria of cell.
In the process of cellular respiration, glucose molecules and oxygen react to form ATP molecules. Water and carbon dioxide are released as byproducts from this reaction. The three stages of aerobic cellular respiration are glycolysis, the Krebs cycle, and oxidative phosphorylation.
Therefore, the correct option is D.
