which term best describes an enzyme
An enzyme is a biological catalyst that seeds up chemical reactions.
What is Enzyme?
A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
All biological activities in living things involve chemical reactions, and enzymes regulate the majority of them.
Many of these processes would not occur at a noticeable rate without enzymes. Every element of cell metabolism is catalyzed by enzymes.
Therefore, An enzyme is a biological catalyst that seeds up chemical reactions.

Answer:
b A moveable moveable joint joint that that allows allows back back and and forth forth movementmovement
Explanation:
A moveable joint that allows back and forth movement. Therefore, the correct option is B.
What is moveable joint?A synovial joint, commonly referred to as a movable joint, allows for a variety of motion between bones. Limbs and other areas of the body that require movement have movable joints.
These joints have a synovial membrane that secretes synovial fluid, and they are enclosed in a capsule of connective tissue. This fluid helps lubricate the joint and lower friction as the bones move in closer proximity to each other.
Ball-and-socket joints, pivot joints, saddle joints and gliding joints are some examples of movable joints. Different types and ranges of motion are possible with each type of joint.
Therefore, the correct option is B.

Which organism turns nitrogen back into nitrogen gas?
A. denitrifying bacteria
B. nitrogen fixing bacteria
C. decomposers
D. nitrifying bacteria
Answer:
b
Explanation:
part of the nitrogen cycle
Denitrifying bacteria turns nitrogen back into nitrogen gas. The correct option is A.
What is nitrogen fixation?Any natural or artificial process called nitrogen fixation causes free nitrogen, a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites.
Chemically, nitrogen fixation transforms atmospheric nitrogen into ammonia, which is ingested by living things.
In essence, nitrogen fixation transforms atmospheric nitrogen into a form that plants can use more easily.
Nitrate is transformed back into nitrogen gas by denitrifying bacteria, which then reenters the atmosphere. Runoff and fertilizer-related nitrogen enters the ocean, where it interacts with marine food webs.
Thus, the correct option is A.

Why are enzymes so important in metabolism?
Why is using the presence of chromosomes inside of a cell NOT a reliable method to
determine if the cell is a prokaryote or a eukaryote?
Because both prokaryotic and eukaryotic cells have chromosomes (prokaryotes, and more specifically, bacteria, generally have just one chromosome, but there are some bacteria as well as archaea—which are also prokaryotes—that have multiple chromosomes).
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic
The nucleus of a eukaryotic cell is bounded by internal membrane, therefore, it is distinctive.
In contrast, the nucleus of a prokaryotic cell lacks internal membrane, hence its nucleus is not distinctive.
Chromosomes are Deoxyribonucleic (DNA) molecules that carry genetic information of a cell or organism.
The chromosomes are present in both the eukaryotic and prokaryotic cells. Chromosomes present in the eukaryotic cells are called eukaryotic chromosomes while chromosomes present in the prokaryotic cells are called prokaryotic chromosomes.
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic

. How long has it taken barren rock to become paradise?
Answer:
Volcanoes are created over approximately 10,000-500,000 years by thousands of eruptions -- each lava flow covering the one before it. In the case of oceanic island volcanoes, lava erupts first from fissures, or cracks, on the deep ocean floor. The flows continue to build up and finally an island emerges from the sea.

is a human is apart of earth's lithosphere true or false
Humans utilize the lithosphere for their habitat, but humans are not a part of it. So the statement is false.
What is lithosphere?The outer, solid layer of the Earth is called the lithosphere. The lithosphere gradually thickens over time as the Earth's convection system's cooling surface layer. It is broken up into quite sturdy plates or parts that move independently of one another. Plate tectonics is the term used to describe these lithospheric processes. The crust and highest layer of the mantle are both included in the lithosphere, which floats atop the weaker asthenosphere. The lithosphere comes in two varieties:
The oceanic crust is connected to the oceanic lithosphere.The Continental crust is connected to the Continental lithosphere.When compared to the continental lithosphere, which is generally 150 km thick and is made up of 50 km of crust and 100 km or more of the topmost mantle, the oceanic lithosphere is typically 50–100 km thick (although is not thicker than the crust under the mid-ocean ridges).
The oceanic lithosphere is denser than the continental lithosphere, whose mantle is connected with crust comprised of felsic rocks, and is mostly composed of the mafic crust and ultramafic mantle.
Therefore, the statement is false.

Biofuels are fuels derived directly from living matter. Read this article about a scientist who discovered how one bacterium can transform plants into usable energy. Then answer the following questions. Today, many people read only the headlines of news stories instead of taking time to read the entire article. This habit can lead to misconceptions about the actual story. What misconceptions could someone have by reading just the headline of this article? How are these misconceptions clarified if the entire article is read?
Answer:
The headline suggests that using bacteria to turn plants into biofuel is a simple process. But reading the article reveals that there were many different types of scientists involved in the process. Also, the headline gives the misconception that this process is so simple that it’s ready to be used. But the last paragraph of the article states that this process has only been done on a small scale, and transforming the process for the entire industry would likely be quite difficult.
