Which list of characteristics describes organisms classified as bacteria?
A.Multicellular, prokaryotic, autotrophs or heterotrophs
B.Unicellular, eukaryotic, autotrophs or heterotrophs
C.Unicellular, prokaryotic, autotrophs or heterotrophs
D.Multicellular, eukaryotic, heterotrophs
Unicellular, prokaryotic, autotrophs or heterotrophs characteristics describes organisms classified as bacteria. So, the correct option is C.
What is Bacteria?Bacteria are defined as microscopic, single-celled organisms, which are present in millions, in every environment, both inside and outside other organisms, where some bacteria are harmful, but most are useful. They serve purposes that support many forms of life, both plant and animal, and they are used in industrial and medicinal processes.
Bacteria lack a membrane-bound nucleus and other internal structures, being ranked among unicellular life-forms called prokaryotes. They are unicellular organisms that obtain their nutrition from either autotrophic mode or heterotrophic mode.
Thus, unicellular, prokaryotic, autotrophs or heterotrophs characteristics describes organisms classified as bacteria. So, the correct option is C.

The more homologous structures two species have, the ________ closely related they may be.
Answer:
more closely
Explanation:
The more alike the structures are the more closely related the organisms are to one another.
The more homologous structures two species have, the more closely related they may be, as homologous structures are traits or anatomical features that are similar in different species.
Homologous structures are features that are similar in different organisms because they are inherited from a common ancestor. These features may have different functions in each organism, but they share a similar underlying structure. For example, the bones in the wings of a bird, the arms of a human, and the flippers of a dolphin are all homologous structures, despite having different functions and appearances. The degree of similarity of homologous structures can be used as an indicator of how closely related two species are to each other.

Why can the product of a synthesis reaction never be an element?
Answer:
The hallmark of a synthesis reaction is that a more complex product is formed from the reactants. One easy to recognize type of synthesis reaction occurs when two or more elements combine to form a compound. The other type of synthesis reaction happens when an element and a compound combine to form a new compound.

With an increase in farming comes an increased impact on the environment. Why would increasing amounts of pesticides in the soil and groundwater be bad?
Answer: Pesticides are found as common contaminants in soil, air, water and on non-target organisms in our urban landscapes. Once there, they can harm plants and animals ranging from beneficial soil microorganisms and insects, non-target plants, fish, birds, and other wildlife.

Increasing amounts of pesticides in the soil and groundwater be bad because they are harmful to the health of humans and animals, and they cause very harmful diseases.
What are pesticides?Chemicals known as pesticides are used to control or kill pests that threaten crops on farmlands. These pesticides are harmful to the health of people and animals if consumed, even if they aid the farmer in eliminating his pest problem and probably boost productivity.
Pesticide tolerance, as established by the Environmental Protection Agency (EPA), refers to the quantity of a pesticide chemical that can be applied to a product.
Therefore, growing concentrations of pesticides in the soil and groundwater are problematic, since they endanger both human and animal health and lead to extremely dangerous diseases.

Describe the chemical composition of the Earth's atmosphere. Which elements are abundant? Which are not?
Answer:
Nearly all of the Earth's atmosphere is made up of only five gas es: nitrogen, oxygen, water vapor, argon, and carbon dioxide. Several other compounds are also present. Although this CRC table does not list water va por, air can contain as much as 5% water vapor, more commonly ranging from 1-3%.
Explanation:
Site: Go ogle sorry...
The Earth's atmosphere is primarily composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases such as argon, carbon dioxide, and neon. Water vapor levels vary but can reach around 4%. Additionally, there are trace amounts of various gases, including methane and ozone.
In the Earth's atmosphere, nitrogen and oxygen predominate. At around 78%, nitrogen predominates, with oxygen making up around 21%. These two gases are necessary for maintaining life since oxygen is required for breathing and nitrogen is used by plants and other living things.
Smaller amounts of other gases like neon, carbon dioxide, and argon are also present. Water vapor plays a significant effect on weather and climate, fluctuating but sometimes reaching 4%. Methane, ozone, and other trace gases are present in small levels yet have a big impact on climate, affecting greenhouse effects and atmospheric chemistry.

A cyclist travel 9 km in 30 minutes. What is the students average speed in km/h?
A.14 km/h
B.16 km/h
C.18 km/h
D.20 km/h
The students average speed is 18km/h. So, the correct option is C.
What is Speed and Velocity?Speed is defined as the time rate at which an object is moving along a path, whereas velocity is defined as the rate and direction of motion of an object. Speed is a scalar quantity as it has only magnitude, whereas velocity is a vector quantity as it has both magnitude and direction.
Speed is expressed as
Speed= Distance/ time taken
Velocity is expressed as:
Velocity= Displacement/ Time taken
Both are expressed as meter per second. (m/s)
For above given information,
If student travelled 9km in 30 minutes
So, it will cover in 1hr = 9* 60/30 = 18km/hr
Thus, the students average speed is 18km/h. So, the correct option is C.

How does heart failure affect the lungs?
Carbon dioxide enters the lungs.
Blood leaves the lungs.
Fluid can build up in the lungs.
Too much oxygen enters the lungs.
Answer:
A damaged heart can't pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe.

best answer I could find, hope it helps
Explanation:
Difference between Solid Liquid and Gases
Highly Strong intermolecular forces between the molecules, leads to a definite volume in Solids.

The intermolecular forces are practically non-existent. Thus, there is no definite volume.
Solids have a definite shape to them. Liquids do not have a definite shape.
Gases do not have a definite shape.
The intermolecular space between solids is absent.
The intermolecular space is moderate but present.
The intermolecular space is free-flowing and plenty.
The force of attraction between the molecules is incredibly high.
The force of attraction between molecules is pretty moderate.
There is no intermolecular force of attraction between the molecules.

Evidence:
Reasoning:
Answer:
Stratovolcano Stratovolcanoes
Explanation:
