The culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.
Arctic outbreak"Bursts" of cold air like this are usually confined to the Arctic region thanks to a series of low-pressure systems, says the NWS. However, one of these waves advanced through Canada and "escaped" to the US.
According to experts heard by Reuters, it is a vast mass of icy air in the atmosphere, which brings with it frigid temperatures - which can be prolonged if storms form.
From this information we can conclude that according to the US Weather Service (NWS), the culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?
Α.
Substances are moving rapidly across the cell membrane.
B. ATP is being rapidly consumed near the cellular membrane,
C. Substances are moving from high to low concentrations.
D. Substances are moving through channels in the cell membrane
Answer:D. Substances are moving through channels in the cell membrane
Explanation:
In case of active transport, ATP is being rapidly consumed near the cellular membrane. Thus, the correct option is B.
What is Active transport?Active transport is the movement of molecules or ions across a cellular membrane from a region of its lower concentration to a region of its higher concentration against the concentration gradient of the molecules or ions. Active transport requires cellular energy to achieve this movement of molecules or ions. The cellular energy is supplied in the form of ATP (Adenosine triphosphate) molecules.
The transport of molecules occurs through transport proteins such as carrier proteins and channel proteins against the concentration gradient.
Therefore, the correct option is B.

Compare a water molecule, H2O, to a hydrogen peroxide molecule, H2O2- Which statement is true?
OA. Water and hydrogen peroxide are made from different types of atoms, combined in the same way.
OB. Water and hydrogen peroxide are made from the same types of atoms combined in the same way.
OC. Water and hydrogen peroxide are made from the same types of atoms, but combine in different ways.
OD. Water and hydrogen peroxide are made from different types of atoms, combined in different ways.
Answer:
C, Water and hydrogen peroxide are made from the same types of atoms, but combine in different ways.
Explanation:
Water is H2O, also known as 2 hydrogen atoms and 1 oxygen atom. In Hydrogen peroxide, its 2 hydrogen atoms and 2 oxygen atoms. They both include the same atoms but in different formations.
Compare a water molecule, [tex]H2O[/tex], to a hydrogen peroxide molecule, [tex]H2O2-[/tex].The statement that is true is water and hydrogen peroxide are made from the same types of atoms, but combine in different ways. Thus, option C is correct.
What is water?Water is a compound made up of nitrogen and oxygen. It is an inorganic substance which is odorless as well as tasteless, and it is a trasnparent chemical substance and it is the main constituent of hydrosphere of earth.
The chemical formula of water is [tex]H2O[/tex] and its molar mass is 18.01528 g/mol with density 997 kg/m3. The boiling point of water is 100 degree celsius and melting point of water is 0 degree celsius.
The elements is defined as a substance which cannot be splitted into simpler form or components by any chemical reaction. An element is also known as atom's species that has a particular number of proton.
All the elements such as carbon, oxygen, and hydrogen found in ethanol but when they are seperated from ethanol they have totally different compound. They are pure element and [tex]ethanol[/tex] is a mixture.[tex]ethanol[/tex]
Therefore, Compare a water molecule, [tex]H2O[/tex], to a hydrogen peroxide molecule, [tex]H2O2-[/tex].The statement that is true is water and [tex]hydrogen[/tex][tex]peroxide[/tex] are made from the same types of atoms, but combine in different ways. Thus, option C is correct.

What type of symbiosis occurs when one organism benefits and the other is harmed?
Answer:
Parasitism
Explanation:
In this a parasite takes its food or other needs from the host but later harms the host too.Some examples like leeches who takes blood from our body but harms us tooParasitism is an ecological relationship between two organisms in which one organism benefits while the other organism suffers. It may also be a type of symbiosis.
The majority of microorganisms investigated in medical microbiology are parasitic and prey on human tissue. Parasitic microbes, for instanse, cause cholera, leishmaniasis, and giardia. Any relationship between two or more biological species is referred to as symbiosis. Such relationships are typically long-term and have a significant impact on one or both organisms' fitness. Benefits and physical characteristics distinguish symbiotic relationships. Mutualism, defined as a relationship in which both species benefit, is very common in nature. There are numerous examples of mutualistic bacteria in the abdomen that aid digestion in both humans and animals in microbiology. A commensal relationship is one in which one species benefits while the other is unaffected. Humans have a variety of commensal bacteria in their bodies that do not harm them but are necessary for survival, like when dead skin is consumed by bacteria.

how does the cell membrane of a tube worm maintains a stable environment
Answer:
The cell membrane of a tubeworm is selectively permeable and they prevent minerals in the water from flowing it in the cell of tube worms. By doing this the cell membrane protects the cell from any osmotic damage. By selectively preventing these minerals it maintains the stable environment in the cell

Explanation:
A tissue through which gases are exchanged between the blood and the air in the lungs.
a) stratified squamous epithelium
b) simple squamous epithelium
c) simple culumnar epithelium
d) simple cuboidal epithelium
Answer:
B- simple squamous epithelium.
Explanation:
Alveoli consists of simple squamous epithelium which is the main site for gas exchange. Thus, the correct option is B.
Gas exchange through the process of pulmonary respiration takes place in the alveoli (singular alveolus) of the lungs.
Alveolus is made up of two types of cells - type I and type II alveolar cells.
Type I alveolar cells are simple squamous epithelial cells supported by a thin elastic basement membrane. These cells form a continuous lining of the alveolar membrane and are the main sites for gas exchange.
Type II alveolar cells are septal cells that are present in between the type I cells. They secrete a fluid to keep the surface between the cells moist and it also contain surfactants for reducing the surface tension and preventing the collapse of alveolus.
