Data Analysis:
Part 1: Calculate the percentage of the cell cycle spent in each stage. Number of cells in given stage ÷ total number of cells counted × 100 = % of the cell cycle spent in this stage
Part 2: Using your percentages in part 1, create a graph that represents the time spent in each stage of the cell cycle.
Insert Chart [Hint: don’t forget to consider the relationship between your data and the type of chart to best represent your data]
Conclusion:
Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
Was your hypothesis correct? Why or why not? Be sure to include evidence from the data you collected to support your conclusion.
Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.
Questions:
Using what you have learned in the lesson and the virtual lab activity, answer the following questions in complete sentences.
What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
If your observation had not been restricted to the tip of the onion root, how would the results be different?
The distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.
What is the cell cycle?The cell cycle is a series of well-defined steps in the life of a cell that begins with cell growth and end with its division.
The cell division has a series of steps that may be classified according to the phenomena that occur in these phases.
For example, chromosomes condense during the first stage of cell division (prophase), where they migrate to the equatorial plate at metaphase.
In conclusion, the distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

which adaptation do ferns, gymnosperms, and angiosperms have that mosses do not have?
Answer:
pollen and seeds
The adaptation do ferns, gymnosperms, and angiosperms have that mosses do not have they have seeds and pollen for reproduction.
What do mosses not have?Mosses make up the majority of bryophytic plants. They are small plants with a simple structure, they do not have conducting vessels, flowers and seeds.
Ferns have a vascular system that transports food, water and minerals to the upper parts through hair-like roots. Mosses do not have true roots or a vascular system. Instead, they absorb water and minerals from the soil where they grow.

what kind of punch do a jelly fish like
Answer:
a smack
Explanation:
Answer:
Jelly fish like a smack punch.
Explanation:
The mystery of what kind of punch a jellyfish like matched in beautifully with the show's theme - and explained why they're dubbed Scorpion. Scorpions are strongly loyal to the other members of their cyclone group. As they solve their cases, the squad surely creates a ruckus! Scorpions, like other scorpions, have very hard shells and are disliked by many people. A smack is a bunch of jellyfish, and the answer to the riddle is a clever play on the term punch. And, of course, this is what the marines called the team at the start of the show when they intended to make fun of them.

which microscope would be best to look at the wings of two different butterflies to determine which is a monarch butterfly and which is a viceroy butterfly?
To determine the difference between a monarch butterfly and a viceroy butterfly, it would be best to use a microscope that has high magnification and resolution, such as a compound light microscope or an electron microscope.
What is a microscope?A microscope is an optical instrument that is used to magnify small objects or details, such as cells or tissues, so that they can be studied or observed more closely. There are various types of microscopes available, including compound light microscopes, scanning electron microscopes, and transmission electron microscopes, which use different principles to produce magnified images of the objects being examined.
A compound light microscope would allow you to see the structures of the wings in detail, while an electron microscope would provide even higher resolution images, but would require the wings to be coated in a thin layer of gold or other metal in order to be viewed. Both of these types of microscopes would allow you to see the fine details of the wings and compare them to determine which is a monarch butterfly and which is a viceroy butterfly.

Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.
Answer: the answer is A
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.
The illustration below represents____,
which is responsible for genetic diversity.
Answer: Crossing over
Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️
The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.
What is Crossing over?Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.
Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.
Therefore, the correct option is B.

Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”

Answer:
Eggs and fried chicken with mentally stabled fries

Match the digestive organ on the left with its function.
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
