4.Diffusion

Explanation:

Diffusion if the movement of particles from a region of high concentration (where there is many) to a region of low concentration (where there is less) until it is evenly distributed.

The cell spends less time in the M phase, also known as the mitotic phase, where the actual division of the cell takes place.

During this phase, the cell undergoes mitosis or meiosis, depending on the type of cell, resulting in the formation of two daughter cells. In contrast, the interphase is the longest phase of the cell cycle, where the cell grows and carries out its normal metabolic activities.

The R phase, also known as the S phase, is a sub-phase of interphase where DNA replication occurs. Prophase is the first phase of mitosis and is relatively short compared to the M phase as a whole.

During prophase, the chromosomes condense, the nuclear envelope breaks down, and the spindle fibers form. In metaphase, the chromosomes align at the metaphase plate.

During anaphase, the sister chromatids separate and move towards the opposite poles. Finally, during telophase, the spindle fibers disassemble, the nuclear envelope reforms, and cytokinesis occurs, resulting in the division of the cytoplasm and formation of two identical daughter cells.

In terms of the amount of time spent in each phase, interphase is the longest, accounting for about 90% of the cell cycle. M phase, on the other hand, is relatively short, accounting for only about 10% of the cell cycle. Therefore, a cell spends less time in M phase than in interphase.

The answer is fungi.

The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.

What do you mean by predators ?

Predators are animals that hunt, kill, and consume other animals (known as prey) for their sustenance. Predation is a common form of interaction between different species in many ecosystems. Predators come in many different forms, such as mammals, birds, fish, insects, and reptiles.

Predators are typically characterized by certain physical and behavioral adaptations that help them hunt and capture prey. For example, many predators have sharp teeth, claws, or beaks that are used to kill and consume their prey. Others may have specialized hunting techniques or strategies that make them highly effective predators.

The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.

Roadrunners are known to be opportunistic hunters and can feed on a wide range of prey items. They are ground-dwelling birds and use their speed and agility to catch their prey. Roadrunners are also known to eat eggs and young of other birds, including owls.

Owls, on the other hand, are nocturnal predators that are known for their exceptional hearing and vision, which enables them to hunt in low light conditions. They are also skilled hunters and can catch a variety of prey, including rodents, small mammals, and birds.

Therefore, both roadrunners and owls are capable of competing for food, but the level of competition depends on the availability of prey, habitat, and other factors. In general, the competition between these two species is likely to be limited, as roadrunners are diurnal (active during the day) and owls are nocturnal (active at night).

extinction, in which ecosystems change drastically

Explanation:

The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.

It represents Glycolysis, a key metabolic route that produces energy and generates precursors for the production of primary metabolites in plants. Thus, option (C) is correct.

Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.

Answer:

The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".
