You will need two saucepans about the same size with lids, a watch or a clock, water, a stove, two eggs.
Pour equal amounts of water into each saucepan. Make sure both have enough water to cover an egg.
Cover one saucepan with a lid.
Put the saucepans on separate burners of the same size on your stove and turn them on to high.
Start timing to see which pot of water comes to a vigorous boil first. (You’ll have to listen to the covered one to tell when it boils—lifting up the lid will spoil the experiment.)
How much longer does it take the second pot of water to boil?
When the two pots of water are boiling:
Place an egg in each one and cover both pots.
Leave one burner on high heat and lower the other to simmer.
Time them for three minutes then remove both eggs at the same time.
Break the eggs and see if one is more cooked than the other.
Explain your observations and what you can conclude based on what you know about heat and energy conservation.
one egg is hard semi-ish boiled and the other is not at all
The normal sodium level in human blood is 135 mEqjL. If a blood test taken immediately after a meal reveals a sodium level of 150 mEqjL, what will most likely result
Answer:
Causes high blood pressure, heart disease, and stroke.
Explanation:
Increase occur in high blood pressure, heart disease and stroke due to increase in sodium level in the blood. If the meal has no sodium then there is no increase occur in the sodium level in human blood while on the other hand, if the meal has more sodium then there is high increase in sodium level in human blood which causes high blood pressure, heart disease, and stroke.

Explanation:
Enzymes lower the activation energy for a chemical reaction to proceed.
Answer:
The statement is true since one of the main functions of the enzyme is to lower the activation energy so that a chemical reaction to proceed.
Explanation:
Enzymes are specialized protein molecules that contribute to faster chemical reactions. One of the functional characteristics of an enzyme is that it reduces the activation energy for a reaction to occur.
Activation energy is the amount of net energy required for a reaction to occur. By lowering the activation energy, a reaction occurs faster, which is achieved with a biocatalyst such as enzyme.
whats is friction?????
Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Describe endocytosis, phagocytosis, pinocytosis, and exocytosis.
Answer:
Endocytosis: Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle.
Phagocytosis: Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles.
Pinocytosis: Pinocytosis, a process by which liquid droplets are ingested by living cells.
Exocytosis: Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport.
Explanation:
Explain the role of nutritional systems in contributing to the maintenance of homeostasis in organisms.
Answer:
Nutritional Systems are very important when it comes to homeostasis. The body needs certain nutrients when performing the body's daily functions. The body needs nutrients like proteins and carbs because they contain energy. The energy from these nutrients help the body to it's daily tasks and stay healthy.

In which experimental set up shown would you expect the Elodia plant inside a test tube to produce the least amount of oxygen
Answer:
Due to less concentration of carbondioxide gas.
Explanation:
Elodia plant inside a test tube produces the least amount of oxygen due to limited carbondioxide gas that is necessary for photosynthesis process. If a test tube has less amount of carbondioxide gas which is a reactant in photosynthesis so in the end the Elodia plant generates less amount of glucose as well as oxygen while on the other hand, if there is more carbondioxide gas is available to Elodia plant, more oxygen as well as glucose is produced.
Which of the following is an incorrect match? a. endocytosis – substances taken into the cell b. exocytosis – substances secreted from the cell c. pinocytosis – liquids secreted from the cell d. phagocytosis – large particles taken into the cell
Answer:
The correct answer is c.pinocytosis – liquids secreted from the cell
Explanation:
Pinocytosis is a type of endocytosis in which substances are internalized into the cell from the celullar exterior. The components are not secreted from the cell but are uptaken into the cell. This internalization process is characterized by the formation of an invagination of the cell membrane where then is formed a vesicle surrounding the component to be uptaken.
Precipitation falls to the ground and eventually ends up in the ocean. Which of the following is the most direct way for the water to get from the soil to the ocean? A. By way of a recharge zone with a low percolation rate B. By way of a closed watershed C. By way of an open watershed D. By way of thermohaline circulation within an aquifer
Answer: D. By way of thermohaline circulation within an aquifer
Explanation: The most direct way for the water to get from the soil to the ocean is by way of a recharge zone with a low percolation rate. Human activity in the recharge zone can limit the amount water that reaches the aquifer.

John had two different colored rabbits that were brothers, one grey rabbit, and one that was white with black spots. Both of these rabbits' parents were only white and black. Explain the terminology and reasoning for these color differences the brothers compared to their parents.
Answer:
They recombine in the offspring, bringing the total gene count back up to two per trait per animal. This recombination of genetic material from parents into children is why we have such diversity among both people and rabbits.

The house fly, Musca domestica, has a haploid chromosome number of 6. How many chromatids should be present in a diploid, metaphase cell (metaphase of mitosis)
24 chromatids should be present in a diploid, metaphase cell (metaphase of mitosis).
What is mitosis?Chromosome replication and equitable distribution between the two daughter cells occur during the cell division process known as mitosis. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. Hence, mitosis is sometimes referred to as equational division.
There are four phases in mitosis and that is prophase, metaphase, anaphase, and telophase.
Thus, If the house fly has a haploid chromosome number of 6, which means it has 12 chromosomes in a diploid state. When a cell undergoes mitosis, the diploid chromosome number of the cell becomes double. Therefore, there will be 24 chromatids in a diploid metaphase cell.

The moon is roughly one-sixth the size of the earth.
Which statement is true?
The gravitational pull of the moon is greater than the earth because it is larger than earth.
The gravitational pull of the moon is less than the earth because it is smaller.
There is no gravitational pull on the surface of the moon.
The gravitation pull of the moon is the same as the earth because they are both spheres.
Answer:
The gravitational pull of the moon is less than the earth because it is smaller.
Explanation:
Objects with more mass have a larger gravitational pull. Just like stars, which are many, many times more massive than planets, have a larger gravitational pull.

The batteries in a flashlight are Dead and the flashlight no longer works. What happened to the energy that was in the battery
Answer:
See the answer below
Explanation:
When the batteries in a flashlight become dead and the flashlight no longer works, it means that the chemical energy present in the battery has been converted to electrical energy to power the touch and eventually got lost to the environment as heat.
In a typical flashlight that works with batteries, the chemical energy in the batteries is converted to electrical energy, and this powers the bulbs in the flashlight. Gradually, the electrical energy is converted to heat energy and this is lost to the environment by radiation. When all the energy is lost to heat, the batteries are said to be dead and the flashlight stops functioning.

A botanist finds that when compared to pink flowers, the population of purple flowers is very high. Ten years later, the population of purple flowers is nearly gone, and the number of pink flowers has tripled. Why would this be?
Answer:
Because of the reduction or near extinction of the purple flowers noticed by the botanist Ten years after it was in abundance, this fall in the population could be caused by the unfavorable change in the plant's environment. While the pink flowers tripled because some factors in the environment were favorable for its growth.
Explanation:
From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:
1. Disease and pest attack on the purple flowers.
2. The pink flowers developed a good survival mechanism even in adverse conditions.
3. Environmental stress could also come into play on the purple flowers.
4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.
