Can you observe cells with the naked eye? Explain.
Answer:
No
Explanation:
According to science, human beings can't observe cells and other tiny organisms with our naked eyes coz our eyes aren't strong enough to observe but we can use a microscope which has strong lenses.
As cell is a tiny microscopic structure, it can be visible under microscope only.
what are the types of cell ?Cell is the basic unit of any living organism, can be observed in animal, plant, microbes etc; Bacteria are unicellular in nature, all higher eukaryotic organisms are multicellular in nature like plants and animal cell.
The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.
The eukaryotic cells have cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.
It has mitochondria energy house, a cytoskeleton for structure and passes information, and lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.

what name is given to factors that should not change in an experiment, science changes might affect the outcome
Answer: These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

A potential answer to a research question is a(n)
A. theory
B. observation
C. question or problem statement
D. hypothesis
A research question is the basis of the experimental analysis of the subject matter. A hypothesis is said to be the potential solution to a research question. Thus, option D is correct.
What is a hypothesis?The hypothesis has been defined as the supposition that acts as the basis of the research and experiment and has been constituted of some evidence and facts to formulate the research question.
It acts as a starting point for any investigation and research and must be falsifiable. They should be testable in order to determine the verifiability of the research topic. If the tested hypothesis is correct then further research is conducted.
It can also be defined as an educated guess that is based on some prior knowledge and facts that are deduced through experiments.
Therefore, the hypothesis is a potential solution.

Certain traits, such as color blindness, are determined by an X-linked recessive gene. A couple in which both have normal vision have a color-blind son. The probability of this couple having a daughter who is a carrier is
Answer:
A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.
Explanation:
If a woman has only one color blind ‘gene’ she is known as a ‘carrier’ but she won’t be color blind. When she has a child she will give one of her X chromosomes to the child. If she gives the X chromosome with the color blindness ‘gene’ to her son he will be color blind, but if he receives the X chromosome which doesn’t carry the color blindness ‘gene’, he won’t be color blind.
A color blind boy can’t receive a color blind ‘gene’ from his father, even if his father is color blind, because his father can only pass an X chromosome to his daughters.
A color blind daughter therefore must have a father who is color blind and a mother who is a carrier (who has also passed the color blindness ‘gene’ to her daughter). If her father is not color blind, a ‘carrier’ daughter won’t be color blind. A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.
The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process within the cell.
Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.
When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.
The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.
The ribosome represents the actual site of protein synthesis.The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.
