Abiotic components are the non-living, chemical, and physical elements of an ecosystem that have an impact on living things and how ecosystems function, hence option A. fallen leaves is the correct option.
What are abiotic factors in the ecosystem?Temperature, light, water, and other abiotic elements of the ecosystem are examples.
The nonliving components of the environment, or abiotic influences, frequently have a significant impact on living things. Water, sunlight, oxygen, soil, and temperature are examples of abiotic variables.
Abiotic factors are non-living components of an ecosystem that influence their surroundings. Examples could be light, water, and temperature in a terrestrial habitat.
Therefore, abiotic elements in a marine ecosystem would be salinity and ocean currents. A particular ecosystem is produced by the interaction of biotic and abiotic elements.

cell walls, cytoplasm and endoplasmic reticulum
cell membranes, DNA and lysosomes
DNA, cytoplasm and cell membranes
Answer: DNA, cytoplasm and cell membranes
Plants, animals, and bacteria have cytoplasm in common.
Plants, animals and bacteria :Plants are the autotrophic organisms. Animals are heterotrophic organisms. Bacteria are prokaryotes.
Plant cell, animal cell and bacterial cells have cytoplasm in common. DNA is also found in them and chloroplast is found in plant cell only. They help in the site of photosynthesis.
In Bacterial cell membrane bound organelles are absent such as Chloroplast, mitochondria and endoplasmic reticulum.
Cell membrane is also called plasma membrane is present in all plant and animal cell. DNA is a genetic material of the organism. In Higher organisms such as plants and animals DNA is a genetic material and in organisms like Bacteria RNA is present.
Therefore, Plants, animals, and bacteria have cytoplasm in common.

Which event has been responsible for most extinctions?
A. Asteroids striking Earth
B. The evolution of photosynthesis
C. Rapid changes in climate
D. Sudden volcanic eruptions
The event that has been responsible for the most extinctions in the history of life on Earth is likely rapid changes in climate. Option c is correct.
Throughout Earth's history, there have been numerous instances of dramatic climate change, often associated with shifts in ocean circulation patterns, volcanic activity, or other factors. These shifts have led to periods of mass extinction, during which large numbers of species go extinct in a relatively short period of time.
One of the most famous examples is the extinction of the dinosaurs, which was likely caused by a combination of asteroid impact and subsequent climate change. However, other mass extinctions have been associated with purely environmental factors, such as changes in atmospheric composition, sea level, or temperature. Option c is correct.

Answer and Explanation:
There are four phenotypes: tall, short, round, wrinkled
Let us say that for the high trait, tall dominates over short. For the shape trait, round dominates over wrinkled. This is:
T allele determines tall plantst allele determines short plantsR allele determines rounded seedsr allele determines wrinkled seeds.The fact that parental are dihybrid, tells us that their genotypes were TtRr

On the basis of Thomson’s model of an atom, explain how the atom is neutral as a
whole.
Answer:
As per Thomson’s model of an atom, the number of electrons (negatively charged) are
equal to the number of protons (positively charged) in an atom. Hence the +ve and –ve
charges are neutralized by each other that makes atom neutral as a whole.
Explanation:
Hope it's answer you plz mark as Brainlist
Answer:
Explanation:
Accorrding to Thomson's model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere.. Thus, by counterbalancing each other's effect, they make an atom neutral.
