Which of the following is not an example of a marine producer?
A. Cyanobacteria capable of photosynthesis
B. Bacteria that carry out decomposition
C. Phytoplankton
D. Chemosynthetic Archaea
Answer:
B. Bacteria that carry out decomposition
Explanation:
This is your answer because these don't produce anything. These are things that don't produce their own food, but they eat something else. One example on land can be Mushrooms.
So hence, your answer is only B. Bacteria that carry out decompositon

what do fossil fuels hold, what kind of energy do they hold, what is converted into, & what kind of energy
Answer:
Explanation: Energy gained from burning fossil fuels is converted to electricity and heat in commercial power plants. When fossil fuels are burned carbon and hydrogen react with oxygen in air to carbon dioxide (CO2) and water (H2O). During this reaction heat is released which further amplifies the reaction.
What are three ways to conserve resources?
Answer:
Proper utilization of resources and saving them for the future generations is known as resource conservation. Reduce, recycle and reuse are the three common ways to conserve resources.That's my correct answerWhat is the evidence that supports the autogenic hypothesis?
Answer:
Explanation:
The hypothesis is supported by the studies on mitochondria. The mitochondria contains its own DNA and sythesizes many of its RNA and proteins. The mitochondrial protein synthesis machine, the ribosomes are similar to those found in bacteria. Similar to the bacterial cells, the mitochondria also contain circular genome

Neurotransmitters are typically stored in which of the following parts of a neuron?
Answer:
Neurotransmitters are synthesized by neurons and are stored in vesicles, which typically are located in the axon ’s terminal end, also known as the presynaptic terminal. The presynaptic terminal is separated from the neuron or muscle or gland cell onto which it impinges by a gap called the synaptic cleft.
Explanation:
Consider the following two statements about DNA melting temperature:
1) The melting temperature of a sample of DNA is the temperature at which 50% of the double helices in the sample have completely denatured.
2) A molecule with 53% GC base pairs would have a higher melting temperature than a molecule of equivalent length with 53% AT base pairs.
Determine which one of the statements below is CORRECT.
A. Statement 1) and statement 2) are false.
B. Statement 1) and statement 2) are true.
C. Statement 1) is true; statement 2) is false.
D. Statement 1) is false; statement 2) is true.
Given what we know, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.
Why is statement 1 false and 2 is true?Statement 1 states that the melting point of DNA is determined by the denaturalization of 50% of the double helices in the sample. This is not the case, since the DNA melting point is when 50% of the sample becomes single-standard DNA. Statement 2 is true in that a higher concentration of GC base pairs leads to a higher melting point for DNA.
Therefore, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

Your science class has taken swabs throughout the school. The image shows the petri dish containing a bacterial culture that developed from a swab of one computer keyboard in the classroom. You would like to make a detailed observation of the internal structures of the bacteria in your culture. You know that In order to see just their shape, it is necessary to use a magnification of about 400x to 1000x. Based on this, develop a logical argument for using a transmission electron microscope.
The TEM magnifies 1,500,000X and produces a 3D image.
In order to keep the students safe, the bacteria must be dead before viewing with any microscope.
The TEM magnifies up to 2000,000X and you can see great detail including the internal structure of cells.
The TEM produces a 2D image of whatever specimen you are viewing.
A logical argument for using a transmission electron microscope (TEM) is: C. The TEM magnifies up to 2000,000X and you can see great detail including the internal structure of cells.
What is a microscope?A microscope can be defined as an optical device that is typically designed and developed to produce an enlarged (magnified) image of a minute (very small) object, in order to show all the littlest and tiniest details about the object that cannot be seen by the natural human eye.
The types of microscopes.In Science, there are different types of microscopes and these include the following:
Scanning electron microscope.Polarizing microscopeInverted microscopeCompound light microscope.Transmission electron microscope.Ideally, a magnification of about 400x to 1000x is required to see the shape of a bacterial culture. However, a transmission electron microscope (TEM) can magnify up to 2000,000X and as such you can see great detail of a bacterial culture, including the internal structure of their cells.

Where would you find the warmest waters?
deep zone
surface-mixed zone
transition zone
polar zone
Answer:
Surface Mixed Zone, because the warmest is at the surface so it'll get the most sunlight. etc. It *stays* the warmest because warm water is less dense than cool water. Layers in the ocean are very well-defined since the warm water on top will stay warm and the cold water stays cold.

Dna provides the instructions for making what type of macromolecule?.
Answer:
Protiens
Explanation:
DNA's instructions are used to make proteins in a two-step process. First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA.
Which step occurs when RNA polymerase attaches to the promoter DNA? termination of the RNA molecule elongation of the growing RNA molecule initiation of a new polypeptide chain initiation of a new RNA molecule
Initiation of a new RNA molecule is the step that occurs when RNA polymerase attaches to the promoter DNA (Option D).
What is the RNA polymerase enzyme?RNA polymerase is an enzyme used to synthesize RNA during a cellular process called transcription, which first required the binding of this protein with a specific region of the DNA gene sequence called promoter.
Therefore, with this data, we can see that the RNA polymerase is an enzyme that binds to the DNA gene sequence in order to initiate the cell process of transcription.

CELL TRANSPORT: Describe how a large protein and an oxygen molecule will
enter or leave a cell, HINT they do not use the same transport method.
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).
It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell. If the particle is solid, endocytosis is also called phagocytosis. If fluid droplets are taken in, the processes is called pinocytosis.

It helps synthesize DNA. It is a major component of the cell membrane. It is a major component of the cell membrane.
Answer:
The correct answer is - It helps code for proteins.
Explanation:
Nucleic acids are biomolecules that are essential for all life forms, they are of two major types RNA and DNA. In RNA the sugar is ribose whereas in DA deoxyribose sugar is present.
Nucleic acids are helpful in protein synthesis in both types of cells and all organisms. These biomolecule codes for the protein and makes the polypeptide chain made up of amino acids with the help of mRNA and tRNA with ribosomes.
