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

Answers

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

Answers

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.

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.

What have you learn about atoms and the universe

Answers

Answer:

Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.

Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei. This all took place within the first few minutes of the universe's existence

Will water that contains no solute ever stop flowing into a hypertonic solution through osmosis?

Answers

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.
