Answer:
7683.2 Joules
Explanation:
We can calculate potential energy using the equation that is used to calculate the work done by a conservative force, in this case, gravity.
U(x)gravity = mgy
U represents potential energy, m is mass, g is gravity, and y is the height.
U(x) = (80 kg)(9.8 m/s^2)(9.8m)
Potential Energy = 7683.2 Joules

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)
Answers
Question: The House Fly, Musca Domestica, Has A Haploid Chromosome Number Of 6. How Many Chromatids Should Be Present In A Diploid, Somatic, Metaphase Cell? The Answer Is 24.
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.

In which experimental set up shown would you expect the Elodia plant inside a test tube to produce the least amount of oxygen
Answers
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
Answers
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.

Describe endocytosis, phagocytosis, pinocytosis, and exocytosis.
Answers
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.

The batteries in a flashlight are Dead and the flashlight no longer works. What happened to the energy that was in the battery
Answers
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.

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.

Enzymes lower the activation energy for a chemical reaction to proceed.
Answers
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.
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?
Answers
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.
