Answer: exocytosis
Explanation:
- When molecules are too large or too charged to cross the plasma membrane by diffusion or osmosis, they use vesicular transport, also known as exocytosis. In vesicular transport/exocytosis, vesicles allow large molecules to exit the cell because the vesicle fuses with the plasma membrane and its contents spill out.

Option c In mitochondria, exergonic redox reactions provide the energy to establish the proton gradient
Phoimage illustrative of mitochondria Cell organelles called mitochondria, which are membrane-bound, generate the majority of the chemical energy needed to power a cell's metabolic processes (plural: mitochondrion).Adenosine triphosphate is a little molecule that stores the chemical energy generated by the mitochondria (ATP). By using the energy created during the oxidation of the food we eat, oxidative phosphorylation—the traditional function of mitochondria—generates ATP. Most biochemical and physiological processes, including growth, mobility, and equilibrium, all require ATP as their principal energy source. Mitochondria are organelles in cells that transform food energy into a form that cells can utilise. The fluid around the nucleus of each cell contains hundreds to thousands of mitochondria (the cytoplasm).

How can we differentiate so many different foods if we can only taste four flavors on our tongue: sweet, bitter, sour, and salty?
We can detect sweet, sour, salty, bitter, and savory tastes because of the presence of out taste buds. It has microvilli that are described to be very sensitive microscopic hairs. They are the one responsible for sending the message of taste to the brain so you will be able to know or differentiate the different taste of food. Each taste has a the presence of chamical substances that is stimulating the receptors on the taste buds. We are able to taste our food because of the sensory cells in our taste buds. We identify the flavor of our food by the odor that comes from our sense of smell because flavor includes taste and odor.

The tendency to respond to a conditioned stimulus that is similar, but not identical, to the original conditioned stimulus is called Stimulus generalization.
The capacity to act in a new situation according to a strategy learned in earlier, analogous circumstances is known as stimulus generalization. The challenge is figuring out which elements of the learning circumstances should be applied to all situations.
When an organism's response that was previously conditioned by one stimulus can then be elicited by another stimulus that shares the same properties, this phenomenon is known as stimulus generalization. A conditioned stimulus is a stimulus that may potentially cause a conditioned response.

What is carcinogen?Anything that has the potential to cause cancer is a carcinogen. They fall into three main categories: oncogenic (cancer-causing) viruses, physical carcinogens, and chemical carcinogens (including those derived from biological sources).The majority of carcinogens, either alone or in combination, cause cancer by interacting with cell DNA and impairing healthy cellular function. As a result, a tumour (an abnormal tissue development) eventually develops. Tumors have the capacity to spread (metastasize) from their original sites, invade, and cause dysfunction in other tissues, leading to organ failure and death. The two main ways that carcinogens cause these tumors to develop are through DNA changes that promote cell division and stop cells from being able to self-destruct in response to common triggers like DNA damage or cellular injury (apoptosis).

1. what happens if the number of cod decreases?
2. What would happen if the phytoplankton were removed?
3.
Aquatic ecology would collapse without phytoplankton. Carbon levels would rise if plankton disappeared, causing climate change. Phyotplanktons may generate dangerous algal blooms if cod numbers drop (HABs).
What is phytoplankton?In the same way as terrestrial plants possess chlorophyll and are dependent on sunlight for their survival and growth, phytoplankton, which are sometimes referred to as microalgae, are found in aquatic environments. The vast majority of phytoplankton are buoyant, which allows them to float in the upper layers of the ocean where the sunlight can reach them.
When there is an excessive amount of nutrients available, phytoplankton have the potential to grow out of control and produce toxic algal blooms (HABs). These blooms have the potential to produce exceedingly poisonous chemicals, which can have a negative impact not just on fish and shellfish, but also on animals, birds, and even humans.
