32. warm water bodies
The hurricanes are one of the most devastating storms in the world. They develop over warm bodies of water and then quickly lift up, full of moisture, and move. As they move quickly, they encounter cold fronts, and the collision between the two results in extremely strong winds and enormous amounts of precipitation. The end result is usually lot of damage done to the nature and the human settlements, casualties are very common unfortunately, and there's large floods.
33. warm
The thunderstorms are forming along a warm front. This type of storms is not in the category of the most dangerous ones, but it is also not a one to be underestimated. The thunderstorms form along a warm front that has gathered a lot of moisture in it. It is a quick moving, warm, moist air mass, and it manage to produce short lasting, but very heavy rainfall, and lot of thunderstorms, with the thunderstorms being particularly dangerous.
34. snowstorms
The snowstorms are type of severe weather condition that occurs in winter. This type of storm may not sound as terrifying as hurricane or a tornado, but it can be equally dangerous, occasionally even more dangerous. The snowstorms bring in very cold winds, significant drop in the temperatures, and enormous amounts of snowfall. The snow can reach several meters in height, and supported by the ice, it is capable of destroying even houses because of its weight. The electrical lines are often destroyed as well, the roads are blocked, the movement in general is almost impossible, so almost always there are casualties because of it.
35. 74 mph
The hurricanes are one of the most dangerous storms, and one of the reasons for that is the strength of the wind they produce. In order for a storm to be classified as a hurricane, it has to have a wind speed of at least 74 mph. The hurricanes are classified in 5 categories according to the wind speeds, and even though the minimum is already a very high wind speed, the highest ones are capable of ripping of houses, large trees with their roots, and pretty much everything on their way.
36. falling and flying debris
The tornadoes are one of the most dangerous storms, and their epicenter are the United States. This type of storm is well know for its very elongated inverse cone shape, quick movement, and very strong winds. The wind speed of the tornadoes is one of the biggest concerns as it can kill easily, but it is not the only problem. The biggest problem, and the most casualties caused by the tornadoes are because of the falling and flying debris that the tornado has picked up along the way, and the debris may include anything from large rocks, to pieces of objects, and even large animals.
37. exercises
The hypothermia is one of the most common killers when it comes to people being exposed to low temperatures. While the best way to avoid hypothermia is to get out of the cold weather and go somewhere warm, that is not always possible, as mostly it is the people that are not able to get to warm place that suffer from it. The most commonly recommended thing to do is to do exercises like the jumping jacks or flapping the arms. These two exercises are recommended because they quickly manage to increase the blood flow, especially at the tips of the fingers and toes.
38. first aid kit, water, non-perishable food
In order for the people to be able to stand a chance to survive in case they are trapped for some time because of a hurricane, they should be well prepared. While there are numerous things that are recommended, there few that are on the top of the list and are necessary. The most important things to have are a first aid kit, as injuries are very common, water, around 1 gallon per person per day, and non-perishable food in order to have safe supplies of nutrition that will not spoil.
39. a. hurricane b. snowstorm c. tornado d. thunderstorm
There are numerous different types of storms, all of which have their own unique characteristics. They can all be dangerous in their own way. Some produce strong and devastating thunderstorms, some have very powerful winds, some cause intense rainfall and floods, some heavy snowfall and frost. Each can be devastating, and for each of them there are specific ways for protection, including having certain supplies, and having a good warning system that can warn the people in time about the danger.
40. southern and southeastern
The United States are the country in the world that has by far the most tornadoes. Not that the United States have the most tornadoes in the world, but they are also the strongest and largest ones as well. The parts of the country that are the most affected are the southern and southeastern part, where the tornadoes rage in certain parts of the year and cause enormous damage, and unfortunately casualties. The tornadoes manage to destroy pretty much everything on their way, and staying safe from them is very hard and there's no ways that provide total security.
When will a cell have a high degree of potency?
A. During cell specialization
B. Prior to cell specialization
C. After cell specialization
D. Adjacent to cell specialization
Answer:
B. Prior to cell specialization
Explanation:
Ability of a cell to differentiate into other cell types is called as its potency. A totipotent cell has can differentiate into whole individual as it has ability to give rise to all the parts of the multicellular organism. A cell has higher degree of potency before its differentiation. Once the cells are differentiated into specific cell types, they lose their potency.
Final answer:
A cell has a high degree of potency b) prior to cell specialization, as it can still differentiate into various cell types. During differentiation, cells specialize, resulting in the loss of some potency and lead to unique characteristics for each cell type.
Explanation:
A cell will have a high degree of potency prior to cell specialization. Potency refers to a cell's ability to differentiate into different types of cells. Before specialization, cells can become any type of cell within the organism, which is why they are considered to be highly potent. As cells undergo the process of differentiation, they become more specialized and lose some of their potency. This is a one-way process, meaning that once a cell has specialized, it typically cannot go back to being a potent stem cell.
The differentiation of cells is a key stage in development where cells become specialized in their size, shape, metabolic activity, and overall function. While all cells contain the same DNA, they only express certain genes that are necessary for their specific functions, akin to how different actors in a movie only read their parts of the script, resulting in unique characteristics for each cell type.
Therefore, the correct answer to the question, "When will a cell have a high degree of potency?" is B. Prior to cell specialization.
A ______ usually develops in the late summer over tropical waters.
A) Drought

What process can change igneous rock into sedimentary rock ?
Igneous rock can be transformed into sedimentary rock through weathering and erosion, which breaks down the rock into sediments.
Initially, igneous rocks on Earth's surface are exposed to weathering and erosion, which are processes that break down the rocks physically and chemically into smaller fragments. These fragments, once detached, are transported by agents like water, wind, or ice, a process called erosion. Eventually, these sediments are deposited, accumulating in places often underwater. Over time, the accumulated sediments undergo compaction and cementation, which are the key stages in the transformation of loose sediments into solid sedimentary rock. Compaction occurs as the weight of overlying sediments compresses the deeper layers, squeezing out water and reducing the space between particles. During cementation, minerals precipitate from water and fill the spaces between sediment particles, effectively gluing them together. This results in the formation of sedimentary rock layers, characterized by their strata.

The timely removal of crops from the field is called
Answer:
harvesting or harvest
Explanation:
The term 'timely removal of crops' refers to harvesting, but the question seems to involve practices like slash-and-burn, known as swidden or shifting cultivation, and crop rotation. These practices help maintain soil fertility and prevent nutrient depletion in agricultural areas.
However, the description provided seems to reference a variety of agricultural practices that involve clearing land for farming. One such practice is slash-and-burn agriculture, also known as swidden or shifting cultivation, where land is cleared by cutting and burning vegetation. Crops are planted for several seasons, after which the plot is left to rejuvenate while the farmer moves on to a new area. This cycle allows the soil to recover and prevents the depletion of nutrients. Another related concept is crop rotation, where the crops are changed in a particular field to prevent exhausting the soil. Rotating crops contributes to soil health and helps manage pests and diseases.

How do cells in a multicellular organism become specialized?
Answer: Cell specialization or cell differentiation is a process of converting generic cells in the body into specialized cells. The specialized cells can perform a certain function within the body. The cell specialization occurs in two stages of a multicellular organism.
i hope this helps yu can probaly find more on https://pediaa.com/how-do-cells-become-specialized/ :)
Answer:
Cells becomes specialized through cell differentiation
Explanation:
Cell differentiation is the process by which the cell in a multi cellular organism gets differentiated.
Basically the function of a cell is determined by DNA. During cell division identical cells are produced with varied genetic identity and this "variation in genetic identity" causes different cells to perform different function. The DNA of a cell with specific genetic area is expressed based on the functionality of the cell irrespective of the expression of entire DNA areas.

The given punnett square shows cross between parent 1 with genotype "Tt" and parent 2 with genotype "tt". Parent 1 forms two types of gamete which are "T" and "t" while parent 2 forms all gamete with "t" only. Random crossing of these gametes gives the genotype ratio= 1 Tt : 1 tt.
After three half- lives, a sample contains 10 grams of parent isotopes. How many grams of the parent isotope were present to start?
its not for biology..... its for Earth/Space Science
Answer: Initial amount of parent isotope present in the sample was 80 grams.
Explanation: Initial amount was= 80 grams
The sample undergone radioactive decay and after first half-life, it has= 40 grams (half of initial amount)
after second half-life, it has= 20 grams
And after third half-life, it has= 10 grams
Thus, the sample at present has 10 grams and initially had 80 grams of the parent isotope materials.
Answer:
The answer is 80
Explanation:
a half lives takes away half of an amount, in the question it said 3 half- lives.
the only posible answer is 80.
FIRST half lives: 80-40=40
SECOND half lives: 40-20=20
THIRD half lives: 20-10=10
80 is the only way to get to 10 with three half-lives.

George Brooks and his colleagues found that pyruvic acid produced through glycolysis can be used in aerobic respiration or converted to lactic acid in muscle cells, with lactic acid later being reconverted into pyruvic acid for further energy production. These findings have significant implications in athletic training, helping athletes understand how to manage lactic acid build up and utilize metabolic processes for optimizing muscular performance.
Explanation:George Brooks and his colleagues completed research into lactic acid in muscle cells. This research discovered that during exercise, pyruvic acid, formed as a product of glycolysis, can either be used in aerobic respiration or converted to lactic acid. This process involves the enzyme lactate dehydrogenase (LDH).
It was initially thought that an accumulation of lactic acid caused symptoms such as muscle stiffness, fatigue, and soreness. However, newer research conflicts with this. Now, it's understood that once lactic acid has been removed from the muscle and circulated to the liver, it can be reconverted into pyruvic acid and catabolized further for energy.
One significant application of these findings in the field of athletic training is understanding that in the absorptive state following intensive exercise, muscle cells can convert excess glucose to glycogen for storage. Additionally, amino acids are utilized in synthesizing actin and myosin, the proteins responsible for rebuilding muscle fibers.
Furthermore, understanding these metabolic processes in muscle fibers can help devise methods of training and recovery that optimize muscular performance. This understanding can also help individuals increase muscle endurance and delay fatigue by managing the buildup and removal of lactic acid in muscle cells during and after exercise.

Answer:
A. The atom determines the chemical property of an element.
Explanation:
Answer:
A. The atom determines the chemical property of an element.
Explanation:
An atom is made up protons, electrons and neutrons. The atoms valance electrons determine its chemical properties. For example, Na has 1 valance electron. Na just like all other alkali elements lose that one outermost electron to form a cation thus gaining an octet. Because of the one valance electron, alkali elements show metallic property and other chemical properties. If an atom has an unstable nucleus then it becomes radioactive.
