Answer: d, seasonal cycles
Explanation: it doesn't affect the population.
The delay between the atrial and ventricular contractions is caused by the atrioventricular node (AV node). The AV node is a small cluster of cells located between the atria and ventricles.
It acts as a gatekeeper, slowing down the electrical signal from the atria so that the ventricles have time to fill with blood before they contract.
There are two main reasons for the delay at the AV node:
The AV node cells have a high threshold for depolarization. This means that they need to be depolarized to a higher level than the cells in the atria before they will fire an action potential.
The AV node cells have a long refractory period. This means that they cannot be re-excited for a period of time after they have fired an action potential.
The combination of these two factors creates a delay of about 0.12 seconds between the atrial and ventricular contractions. This delay is essential for proper heart function, as it allows the ventricles to fill with blood before they contract.

survival.
Answer: Temperature, Humidity(can go hand in hand), pH, and sunlight to name a few
Three environmental factors that affect Salmonellagrowth and survival are temperature, moisture, and pH level.
Salmonella is a type of bacteria that can cause food poisoning in humans. It is commonly found in raw or undercooked poultry, eggs, and other food products. The growth and survival of Salmonella are influenced by various environmental factors. Three important factors that affect Salmonella growth and survival are temperature, moisture, and pH level.
Temperature: Salmonella bacteria thrive in temperatures between 40°F (4°C) and 140°F (60°C). This temperature range is known as the danger zone for bacterial growth. At temperatures below 40°F, Salmonella growth slows down, while temperatures above 140°F can kill the bacteria.
Moisture: Salmonella requires a moist environment to grow and survive. High levels of moisture provide favorable conditions for bacterial growth. Dry environments, on the other hand, can inhibit Salmonella growth.
pH Level: Salmonella bacteria prefer a slightly acidic to neutral pH range of 4.0 to 7.0. Extreme pH levels, either highly acidic or highly alkaline, can inhibit the growth of Salmonella.
Understanding these environmental factors is crucial in preventing the growth and spread of Salmonella in food and other environments.
