Assuming there has been no geological activity to disturb the order of the rock layers, rock layer is (b) The oldest rocks at Location.
What are the Finding of the oldest rocks?The global is a tougher challenge than it'd seem. Earth's crust is a dynamic gadget and is constantly in motion, so rocks are always being moved around, created and melted down withinside the fantastic geological recycling programThe oldest zircon dates are 4.36 billion years. Before this study, the oldest dated rocks have been from a frame of rock called the Acasta Gneiss withinside the Northwest Territories, which can be 4.03 billion years old.

A new predator is introduced to an aquatic ecosystem. In a population of fish that live there, very small fish are more easily able to hide from the predators, and very large fish cannot be easily eaten by predators. What type of natural selection is acting on the population, and what will be the expected result?
A.Stabilizing selection: Since both extremes are selected against, the fish population will remain about the same.
B.Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, small and large fish will be common.
C.Stabilizing selection: Over time the fish population will change. Medium-sized fish will become rare, small and large fish will be common.
D.Disruptive selection: Since both extremes are selected against, the fish population will remain about the same.
Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, and small and large fish will be common is a type of natural selection that is acting on the given population. So, it's B.
What do you mean by Ecosystem?An ecosystem may be defined as any place or area where the members of different species or communities live together and interact with one another for the purpose of food, shelter, and space.
As predators are only able to attack the moderate-sized fishes, so the population of moderate-sized fishes may decline in the aquatic ecosystem, while extremely short and large fishes are able to maintain their population at the same pace.
Therefore, the correct option for this question is B.

The organization of a organism from smallest to largest is Cell, tissue, organ, organ system, organism
True
False
The cellular organization from smallest to largest is cells, tissues, organ, organ system and organism. Hence, the given order is true.
What is cellular organization ?Cellular organization refers to the hierarchical arrangement of cells in living organisms. All living organisms are composed of one or more cells, and the way in which cells are organized within an organism is critical to its overall function and survival.
At the smallest level, cells are organized into organelles, which are specialized structures within the cell that perform specific functions. For example, mitochondria are organelles that produce energy for the cell.
Cells are then organized into tissues, which are groups of cells that work together to perform a specific function. Examples of tissues include muscle tissue, which is responsible for movement, and nerve tissue, which is responsible for transmitting signals throughout the body.
Tissues are then organized into organs, which are structures that are made up of two or more different tissues and perform a specific function. For example, the heart is an organ that is made up of muscle tissue and nerve tissue and is responsible for pumping blood throughout the body.
Finally, organs are organized into organ systems, which are groups of organs that work together to perform a specific function. For example, the circulatory system is an organ system that includes the heart, blood vessels, and blood and is responsible for transporting oxygen and nutrients throughout the body.

and through human activities like burning of fossil fuels...
The respiration process adds carbon dioxide to the air. Therefore, option "C" is correct.
What is respiration?A metabolic process known as respiration involves an organism's living cells taking in oxygen and releasing carbon dioxide from the oxidation of complex organic substances to obtain energy (ATP). High-impact breath happens in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The synthetic condition is C6H12O6 + 6O2 → 6CO2 + 6H2O.
There are two types of respiration that occur in nature that is aerobic respiration and anaerobic respiration. Aerobic respiration involves the use of oxygen for oxidation and later oxygen is not used.
Therefore, respiration is the cellular process that happens in all organisms.
