If there are none, say that prokaryotic cells have a cell wall, large vacole and chloroplast.

An isolated carbon atom (atomic number 6) has an electronic configuration of 1s2 2s2 2p2. In this configuration, there are two unpaired electrons present in the 2p orbital.

Isolation refers to the state of being separated, detached, or cut off from others or one's surroundings. It can occur on a physical, social, or emotional level. When someone is isolated, they may experience a lack of contact, support, or interaction with others, leading to feelings of loneliness, disconnection, and exclusion. Isolation can have negative impacts on mental and emotional well-being, as humans are social beings who thrive on social connections and interactions. It is important to recognize and address feelings of isolation to promote overall health and well-being. Supportive relationships, community engagement, and seeking professional help are ways to combat isolatio

It is impossible to completely sterilize the human skin due to the presence of natural microbiota. The skin is the largest organ in the human body, and it is covered by a diverse microbial community, which includes bacteria, fungi, and viruses. This community is collectively known as the skin microbiome.

The skin microbiome plays an essential role in maintaining skin health by protecting against pathogens, regulating immune function, and preventing infection. Attempts to completely sterilize the skin can disrupt this delicate balance and cause damage to the skin's barrier function.

Although it is impossible to completely sterilize the skin, good hygiene practices such as regular hand washing and avoiding sharing personal items can help reduce the risk of transmitting harmful microorganisms. Additionally, medical professionals use various antiseptic techniques to minimize the risk of infection during invasive procedures such as surgery.

Overall, the natural microbiota of the skin makes complete sterilization impossible, but proper hygiene practices can help minimize the risk of infection.

Fire reproduces if a spark from the original fire as it lands on another object is reasoning.

Reasoning is the ability or process of thinking and process thing in a logical and factual way. The use of a reason for a situation is reasoning and it is a sensible way of thinking.

Fire needs oxygen to spark up and fire up. When there are good ventilation and fire breaks up and burns with full light and heat. If the spark of fire burns other objects, it also burned up due to fire. This is the proper and factual reason for burning a fire.

Evidence is when given some evidence for the given statement but in the statement, the evidence is not given, just a reason is given for the burning of fire.

It depends. Please look at the explanation.

Explanation:

Since the question does specify what the reference was, I will be referring to different time periods. This question is a bit complicated, and I apologize in advance that this answer will most likely be very long.

There are many things that affect how often these blooms are reported. For example, when people still lived in close colonies, they covered less water mass than now (also because of the population differences). However back then, there probably wasn't as many algae blooms since the environment wasn't as contaminated.

1.) People are more likely to report these sightings when they don't know much on the subject - If you look in the past, humans have been trying to create a reason for everything. When there was a natural disaster, and  they didn't understand it, they said that the divine beings were angry. When people got lucky, they called it fate, or that they had the favor of the god/God/god(s). In the 1700s, the first algae bloom was reported. Of course, they didn't have enough information on the matter and tried to blame it on something. If they saw it again, they might take it as a bad omen and immediately report it. This would increase the percentage of blooms reported that happened around the civilization.

2.) There is a matter of population difference -  In the 1800s, there was approximately one billion people in the world. This population is nearly two times the population in 1700 CE (population: 600 million). Of course, seeing as people started to migrate / spread out across the land, there would be more rivers/bodies of water that are near a civilization. This means that they should, hypothetically, have a larger number of blooms reported. (Note that it is a larger number and not percentage)

3.) Environmental Contamination - As the population rapidly grows, there is a lot more inventions, experiments, technology, and development happening. This also means that the over populated cities such as London would have worse sanitary conditions. (This statement applies only to the before bacteria & other microorganisms were discovered.) Improper disposal of waste would ultimately lead to land and water contamination, which results in more algae blooms appearing. Trash could have also gone to the middle of the ocean. Algae blooms that appear in the middle of the ocean most likely wouldn't get reported, as it isn't located near a civilization. In this case, the percentage would decrease, since the ratio would be off.

Conclusion:

There are many factors that are involved in this complicated problem. It is  also impossible for me to decide which had more algae blooms reported, also because it wasn't specified whether the question was asking for the number or the percentage. Since I cannot properly answer this problem, I listed the major things to think about.

The type of weather can people in this area expect are Fewer clouds, Less precipitation, and Snowfall.

A high-pressure system is usually associated with sinking air, which suppresses cloud formation and results in clear skies and less cloud cover.

As a result, people in areas where a high-pressure system is approaching should expect fewer clouds.

Furthermore, because sinking air can suppress precipitation, high-pressure systems are usually associated with drier conditions. As a result, people in areas where a high-pressure system is moving in can expect less precipitation.

Furthermore, colder temperatures can be brought by high-pressure systems because they frequently push cooler air down from the upper atmosphere.

If the temperatures are cold enough, the precipitation that does fall may be snowfall rather than rain.

Thus, people in an area where a high-pressure system is moving in can expect clear skies, lower chances of precipitation, and possibly colder temperatures with the potential for snowfall.

The methods for safely working using aseptic technique are: Autoclaved tips and surface-sterilized tools should be used for all aseptic transfers.

Prior to transferring microorganisms to another medium, sterilize the wire loop by heating it until it glows red hot. Laboratory benches and surfaces should be cleaned with a sterilizing agent such as 70% ethanol before and after each use. The practice of using aseptic technique ensures the safety of both the microbiologist and the culture being grown. Aseptic techniques are a range of techniques used to protect microbiological cultures from being contaminated by other microorganisms that might exist in the surrounding environment.

Aseptic technique refers to any set of procedures that is performed under sterile conditions in order to avoid the introduction of contamination. Aseptic technique is commonly used in the laboratory when working with microorganisms that are sensitive to contamination or infection. In order to safely work using aseptic technique, it is important to follow several guidelines, including using sterilized tools and surfaces, cleaning laboratory benches and surfaces, and using a sterilizing agent such as 70% ethanol before and after each use.
