Patrick loves bubble gum and would like to be able to blow bigger bubbles than anyone else
in Bikini Bottom. To prepare for the Bikini Bottom Big Bubble Contest, he bought five different brands of
bubble gum and needs your help to find the brand that creates the biggest bubbles. Write an experiment to
test the bubble power of the bubble gum brands and help Patrick win the contest.
Answer:
Abstract:
The purpose of the experiment was to determine which brand of bubble gum could inflate the most under a given set of controls.
5 brands were tested under controlled circumstances such as:
- Zero wind space
- Consideration was given for the bubble gum that could achieve the highest size given the maximum chew of 40 times.
- to ensure that a reasonable average was given for each brand, the test was repeated thrice per brand the size per bubble gum was recorded and the time and the average computed.
Introduction:
In this experiment, the brand of bubble gum with the ability to inflate to the biggest size was tested
Hypothesis
The bubble gum with the biggest average size is the best bubble gum to enter the competition with. It guarantees that Patrick's chance of winning under very stringent circumstances is guaranteed.
Procedure
First, Patrick must create a table with 6 columns and 3 rows.
the first column will be the Serial number sectionThe topmost row of each of the five columns will be labelled with one brand of gumPatrick will need an assistant who will help to measure the sizes of each bubble and also act as a time-keeper. For each brand of gum, Patrick will chew for at least 40 times before he starts to inflate them.The timekeeper will, with the help of a stopwatch, measure how long it took to inflate a brand of gum. Each brand will be inflated at 3 times. Each result will be recorded in the rows under the column for that brand.In order to further ensure that there is control, after each inflation, Patrick must chew each gum for 20 timesThe experiment must be carried out in a room that is not windyMaterials
StopwatchElectronic or Manual SpreadsheetIf Manual Spreadsheet then a writing material will be requiredAssistant for observing and recording the time and size of each inflationA mirror this is optional given that there is an assistanta well-lit room void of fan or windA calculator if a manual spreadsheet is used.
Conclusion
Here Patrick will indicate the result of the experiment and calculations.

Compare and contrast animal fats and plant and fish oils
Explanation:
On the other hand, lipids with unsaturated fatty acids (unsaturated fat) tend to be liquid at room temperature and thus they are called 'oils '. Lipids are present in all living organisms including Archaebacteria. ... Fats of animal origin are called as 'animal fat ' and those of plants are called 'plant fats'.
Which of the following is NOT a form of active transport? A) cyclosis B) phagocytosis C) diffusion D) pinocytosis
Diffusion is not active and instead a form of passive transport. So the correct option is option C.
Because diffusion is a non-electrical process, small particles move faster than larger ones. For example, molecules such as oxygen, CO2, and glucose move through cells.
Active transport involves moving molecules from a low-concentration region to a high-concentration region. In contrast to diffusion, active transport involves moving molecules against a concentration gradient.
The term “active” refers to the fact that transport is energy-dependent. Active transport is energy-intensive, whereas diffusion is energy-free.

Write down the secretion, function and deficiency disorders caused by the following gland.
(i) Pancreas (ii) Pituitary (iii) Thyroid gland (iv) Adrenal gland.
Answer:
(I) pancreas - it secretes insulin
it's function is to regulate the sugar levels in blood
if it does not function properly it causes diabetes (sugar)
(ii)pituitary- it secrets growth hormone
it's function is to regulate the growth in human body
if it produces lots of hormone then the body will increase a lot in size known as gigantism
if it produces very less hormone then the body will not increase in size and will be very short known as dwarfism
(III)thyroid gland-it secretes thyroxin
its function is to maintain metabolism growth
lack of iodine makes this gland swell up known as goitre.
(iv)Adrenal gland - it secrets adrenaline
it's function is to help us prepare and respond to stressful situations
because of its malfunction the body does not get enough hormones.

1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are soluble in it. Water is such a good solvent because the molecular structure of a water molecule is polar, having a negative charge at one end and a positive charge at the other end. Which model best represents a water molecule? A. B. C. D.
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

Diatoms are one of the most common types of phytoplankton in marine habitats. Like plants, diatoms contain chlorophyll and produce glucose from which of the following?
CO2 and O2
CO2 and H2O
O2 and ATP
ATP and H2O
Answer:CO2 and H2O
Explanation:
Diatoms produce glucose from CO2 and H2O.
The sun is the only source of energy in the ecosystem. Plants can trap this energy from the sun through the process of photosynthesis. Photosynthesis is the process by which green plants use energy from the sun to combine carbon dioxide and water to form glucose.
Hence, like plants, diatoms contain chlorophyll and produce glucose from from CO2 and H2O.

A classmate argues that Schwann and Schleiden are responsible for the cell theory. How do you respond? Cite facts and use logical reasoning to support your argument.
Answer:
Yes.
Explanation:
Yes, Schwann and Schleiden are responsible for the cell theory, both the scientists presented the cell theory in 1839. I agree with the argument of my classmate because the person who first presented cell theory was both Schwann and Schleiden. Schwann works on plant cell whereas Schleiden works on animal cell and formulate cell theory. So my classmate's argument is right about cell theory.
Schwan and Schleiden proposed the first cell theory, suggesting spontaneous generation. Virchow changed it proposing cell division. After many years and the contribution of many researchers, the modern cell theory emerged.
---------------------------------------------------
Schwann studied animal tissues. Through careful observation, he concluded that all animal tissues were made of cells.
Simultaneously, Schleiden arrives at the same conclusion when studying vegetable tissues.
Around 1830, they met and together proposed the first cell theory. The theory stated that:
1. Every living being is made of cells.
2. Cell is the basic unit of life.
3. Cells are originated from spontaneous generation.
Virchow, who studied human tissues, sow the cell in its dividing process.
He proposed that cells were not originated from spontaneous generation, as Schwann and Schleiden had stated.
Instead, he said that cells were the product of other pre-existing cells and were originated by cellular division.
Virchow rejected the third state of Schwann and Schleiden’s ideas.
According to these sequence of events, the original cell theory changed to
1. Every living being is made of cells.
2. Cell is the basic unit of life.
3. Cells are originated by cellular division.
After many years of continuous studies about cells and their functions, the modern cell theory emerged.
In general terms, the modern theory can be resumed as,
1. Every living being -unicellular or multicellular- is made of cells, which are the most basic units of life.
2. Cell control the vital functions of organisms.
3. Cells proceed from preexistant prokaryotic cells, and are originated by cellular division.
