Answer:
I think the answer would be light-based microscope .
Hope it helps,
I'm not so sure.
A type of microscope that was most recently developed is known as the scanning tunneling microscope. Thus, the correct option for this question is A.
What is a microscope?A microscope may be defined as a type of laboratory instrument which is utilized in order to visualize objects that are too small to be observed by the unaided eye.
With associated the microscope, microscopy is the branch of science that considerably deals with the investigation of small objects and structures with the utilization of a microscope.
A scanning tunneling microscope (STM) is a type of microscope that is significantly utilized in order to determine imaging surfaces at the atomic level. Its development is thought to be done in 1981 by the inventors Gerd Binnig and Heinrich Rohrer. It is later modified in 1986 by IBM Zürich.
Therefore, the scanning tunneling microscope is a type of microscope that was most recently developed. Thus, the correct option for this question is A.

What do DNA and RNA code for?
Answer:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Answer:
"How does/Does only using one brand of makeup, milk makeup that is vegan affect how the skin will react to makeup that doesn’t have many toxic ingredients?"
I would make this more percise and easier to read. It's a little long and wordy.
I would say this instead: How does one brand of milk and vegan makeup affect the skin's reaction to other makeup that has no toxic ingredients?

Answer:
The Skin weren’t preserved at all
Explanation:
One reason why most fossilized animals have incomplete remains is that parts like the skin aren't usually preserved at all. There are however some instances in which the skin are preserved but it’s very rare.
This is because of the action of decomposers on the remains of the body parts and the presence of scavengers which eats the body parts thereby making the remains incomplete.
Will water that contains no solute ever stop flowing into a hypertonic solution through osmosis?
Answer:
No, it will never stop flowing
Explanation:
Osmosis is the movement of water from an area of lower concentration of solute to an area of higher solute concentration through a semi-permeable membrane. If one side of the membrane is completely free of solute, water will move to the hypertonic solution continuously in a bid to achieve equilibrium until all the water completely moves to the hypertonic side. This is because equilibrium cannot be attained since one side is completely void of solute and another has solutes.
It is like having red coloured paint on one side and water on another side of a membrane, and the water moves into the paint compartment and only stops when they both have the same color. No matter how much water moves across, they cannot have the same color on both sides.

What are proteins?Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
Moreover, every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.
Serious protein deficiency can cause swelling, fatty liver, skin degeneration, increase the severity of infections and stunt growth in children. While true deficiency is rare in developed countries, low intake may cause muscle wasting and increase the risk of bone fractures.

Scientists can identify cells by categorizing the different features of a cell by noting down the shape, color, and other physical features. This aspect of science is known as_________ Observation Inference Hypothesis Controlled Experiment
Answer:
Observation
Explanation:
The aspect of science that has to do with the recording of color, shape, and other physical features in order to identify a cell would be observation.
Observation in science is the collection of data via perception or through the use of scientific instruments. Perception generally involves the use of human senses such as sight, touch, taste, and hearing to collect data in order to arrive at a conclusion.
The color, shape, and other physical features of a cell requires a perception of sight. Hence, it involves observation.

Prokaryotic cells do not contain many of the organelles that eukaryotic cells have. Prokaryotic cells do have a primitive form of _____________.
A.) ribosomes
B.) Golgi apparati
C.) mitochondria
D.) chloroplasts
Answer:
Ribosomes
Explanation:
Prokaryotic cells do have a primitive form of ribosomes. Thus, the correct option for this question is A.
What are Prokaryotic cells?Prokaryotic cells may be defined as the types of cells that lack a well-defined nucleus and other membrane-bound cell organelles. The genetic material of a prokaryotic cell is a single chromosome made up of a single strand of DNA.
A Prokaryotic cell typically has a cell membrane or plasma membrane that functions or operates like a protective cover. Golgi apparatus, mitochondria, and chloroplasts are significantly absent in prokaryotic cells. This is because they are membrane-bound cell organelles.
The traces of ribosomes are required for the process of protein synthesis in order to accomplish metabolic activities required for the survival of prokaryotic organisms.
Therefore, prokaryotic cells do have a primitive form of ribosomes. Thus, the correct option for this question is A.
