Answer:
Crossing-over
Explanation:
Crossing-over is a phenomenon that occurs in the Prophase stage of meiosis I. Two chromosomes of a homologous pair comes together in a process called SYNAPSIS to form a TETRAD structure. While the chromosomes synapses, breaks occur at corresponding points in the non-sister chromatids i.e in one chromatid of each chromosome. Since the chromosomes are homologous, breaks at specific points mean that the segments that are broken off contain specific genes i.e. alleles. The broken sections are then exchanged between the chromosomes to form complete new units, and each new recombined chromosome of the pair can go to a different daughter sex cell.
In meiosis, the maternal and paternal chromosomes can be shuffled into daughter cells in many different combinations. The resulting chromosomes are not entirely maternal, neither are they entirely paternal. This ensures genetic variation in sexually reproducing organisms.
TRUE or FALSE ?
TRUE. Foodborne pathogens typically cause gastrointestinal symptoms like nausea, vomiting, diarrhea, and abdominal pain due to contaminated food consumption.
TRUE. Foodborne pathogens, like waterborne pathogens, are certainly pretty probable to reason gastrointestinal symptoms. These microorganisms, including bacteria like Salmonella, E. Coli, and parasites like Giardia, frequently enter the digestive machine thru contaminated food or water.
Once ingested, they could trigger diverse gastrointestinal troubles inclusive of nausea, vomiting, abdominal pain, diarrhea, and in extreme instances, dehydration and electrolyte imbalances.
The body's natural reaction to those pathogens outcomes in the release of pollutants and the infection of the digestive tract, main to the characteristic signs and symptoms.
While a few pathogens may also reason moderate pain, others can cause more critical ailments, specially in prone populations like the aged, youngsters, and those with weakened immune structures.
Preventive measures, consisting of practicing right food dealing with and hygiene, are vital to mitigate the chance of foodborne ailments and their related gastrointestinal signs and symptoms.
To learn more about Pathogens, refer:
TRUE. Foodborne pathogens, like waterborne ones, often cause gastrointestinal symptoms such as nausea, vomiting, diarrhea, and abdominal pain when ingested through contaminated food.
True. Like waterborne microbes, foodborne microorganisms are almost certain to cause gastrointestinal side effects. At the point when polluted food containing destructive microorganisms like microbes, infections, or parasites is devoured, these microorganisms can enter the stomach related framework.
They frequently bother the covering of the stomach and digestive organs, prompting a scope of gastrointestinal issues like queasiness, spewing, loose bowels, stomach torment, and spasms. The seriousness of side effects differs relying upon factors like the kind of microbe and the singular's general wellbeing.
It means a lot to take note of that while most foodborne sicknesses are gentle and determine all alone, some can be extreme or even perilous, particularly for weak populaces like the old, small kids, pregnant people, and those with debilitated insusceptible frameworks.
Thusly, rehearsing appropriate sanitation measures, including careful cooking, sterile food dealing with, and keeping away from cross-pollution, is vital to limit the gamble of ingesting foodborne microbes and encountering related gastrointestinal trouble.

Answer:
Stolon
Explanation:
Population density is calculated by dividing the total population of a specific area by the total land area of that area.
The formula for population density is:
Population density = Total population / Total land area
To calculate population density, you need to know the total population and the total land area of the area you are studying. For example, let's say we want to calculate the population density of a city with a population of 500,000 people and a land area of 100 square kilometers.
Using the formula, we can calculate the population density as follows:
Population density = 500,000 / 100 = 5,000 people per square kilometer
This means that in the city we are studying, there are approximately 5,000 people living in each square kilometer of land.
Population density is an important measure that helps us understand how crowded or sparse a particular area is in terms of population. It is often used to compare different regions or to analyze population trends over time. By calculating population density, we can gain insights into the distribution of people and understand the impact of population growth on a specific area.
