Which of the following is not a natural cause of extinction?
a.competition due to overpopulation
b.introduction of non-native species
c.catastrophic events
d.disease
Answer:
Introduction of Non-native species would be the answer. ( B )
Explanation:
Now let's break it down.
A. Competition due to overpopulation
Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.
B. Introduction of Non- native species.
So what does it mean by Non-native species?
It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.
C. Catastrophic Events
Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.
D. Disease
This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.
So, the Answer would be B.
HOPE THIS ANSWER HELPED :)Among the given options, the one that is a natural cause of extinction would be:
b). Introduction of non-native species.
'Non-native species' are described as the species that are introduced to an ecosystem different from its native habitat.
These species are severe threat to the existing ecosystem of the new habitat including plants, animals, aquatic life, etc. where they've been shifted.
Thus, it is not a natural cause as these species are not naturally introduced but the humans introduce them.
They turn so dominating to get their food and other things that it lead not only harmful but also lead to the extinction of the native species.
Hence, option b is the correct answer.

In vesicular transport, __________ transport materials into and out of the cell using _______.
Endocytosis and exocytosis transport materials into and out of the cell using vesicles.
Endocytosis is called the process by which cells incorporate into them molecules, large or small, which are covered by the formation of a vesicle that detaches into the cell, forming phagocytic vesicles.In exocytosis, the proteins or molecules produced in the endoplasmic reticulum are wrapped in a vesicle towards the Golgi apparatus, where they are released to be used by other cells or by the body in different processes.Therefore, we can conclude that exocytosis and endocytosis are the biological processes responsible for the transport of particles and substances into and out of the cell.

which of the following happens to a cell in hypotonic solution
A- The cell gains water and expands
B- The cell stays the same
C- The cell loses water and shrivels
D- Water moves out of the cell
Answer:
In a hypotonic solution, the solute concentration is lower than inside the cell. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies
Hypotonic solutions have lower solute concentrations than cells. If water keeps entering the cell, it can strain the membrane until the cell bursts and dies. Therefore, option (A) is correct.
What is hypotonic solution?In comparison to another solution, a hypotonic solution will have a lower solute concentration because of its composition. Without another solution to compare it to, it is impossible to determine whether a solution is hypotonic, isotonic, or hypertonic. A solution is said to be hypotonic when it has a relatively low concentration of solutes in comparison to another solution.
As a consequence of this, the solute concentration is lower in a hypotonic solution than it is inside of the cell. If the water continues to enter the cell, it has the potential to stretch the cell membrane to the point where the cell lyses and dies as a result of the rupture.

what are two organisms in the food web that have a predator-prey relationship? i need examples
Answer:
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
What do you mean by predator-prey relationship?In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.
Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.
The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.

Explanation:
My teacher sent me back my ws and that was a question i got wrong
Fermentation is a chemical process by which molecules such as glucose are broken down anaerobically. Therefore, option (A) is correct.
What do you mean by fermentation?Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Moreover, fermentation occurs in the absence of oxygen (anaerobic conditions), and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation.
Hence, fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.

Define the following types of sexual reproduction: Binary fission, budding. fragmentation, parthenogenesis
Answer:
Binary fission-Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Budding-Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud.
Fragmentation-Fragmentation in multicellular organisms is a form of asexual reproduction in which an organism is split into fragments. Each of these fragments develop into matured organism, full grown individuals that are genetically and morphologically identical to their parents.
Parthenogenesis-
Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth,” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.
