Fireflies emit light. The production of light by an organism is called bioluminescence. To generate visible light, cells in a firefly's tail produce thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of the following best describes how the luciferase enzyme speeds up the chemical reaction? F Luciferase increases the amount of time the light is visible. G Luciferase decreases the amount of energy required for the reaction to start. H Luciferase increases the number of sites on luciferin that must bind to oxygen. J Luciferase decreases the temperature of the environment inside the body of the firefly.

Explanation:
b
The description that best describes how the luciferase enzyme speeds up the chemical reaction is - Luciferase decreases the amount of energy required for the reaction to start.
Fireflies generate a chemical reaction that allows their body to emit light, inside their body. This light generation is called bioluminescence. This process involves various steps:
Oxygen binds with calcium, luciferin chemical with ATP to make oxyluciferin.In the body of fireflies, there is the production of an enzyme called luciferase.This chemical reaction takes place in presence of luciferase that speeds up this reaction by decreasing the activation energy of the reaction.At the end of the reaction body of fireflies light up.Thus, the correct answer is - Luciferase decreases the amount of energy required for the reaction to start.

Interpret each rule of Kartilya ng Katipunan in one word
Answer:
Throughout the clarification category below, the definition including its query is mentioned.
Explanation:
The Kartilya ng Katipunan acted as either the reference book or field guide for the organization's new representatives, which set out other principles and expectations including its party. Emilio Jacinto published the first version of Kautilya. The revamped Decalogue was later published by Andrés Bonifacio. It would never be released although Bonifacio thought that Kartilya of Jacinto seemed equivalent to what he has already created.which is smallest to largest form?
human tissue, human cell, bacterial cell, virus, human organ, human organ system.
Answer:
Explanation:
virus, bacterial cell, human cell, human tissue, human organ, human organ system.
The smallest to largest forms in the order:
VirusBacterial cellHuman cellHuman tissueHuman organHuman organ system.The Virus comes first as it is much smaller than the Bacterial cell and can be
viewed with an electron microscope which has a higher magnification
Cells are the smallest unit of life and they aggregate to form tissues . The
tissues then aggregate to form organs and organs to organ system which is
why the human cell comes next followed by the Human tissue, Human organ
and lastly Human Organ systems.

Which of the following is not a function of the cell membrane?
•It supports and shapes the cell.
•It assists in cell division.
•It positions organelles.
•It provides energy to the cell.
Answer:
A is the right answer
Explanation:
The cell wall is the outermost layer of the cell. It surrounds the cell membrane and provides these cells with structural support and definite shape. It prevents the over-expansion of the cell when water enters the cell.

during which phase of the cell cycle does most cell growth occur
Cell growth occurs constantly throughout interphase. S phase is the time when all the cell's chromosomes are replicated so significant cell growth occurs here, but during both G1 and G2 cell growth occurs.
hope this helps
During the interphase of the cell cycle most cell growth takes place.
What is cell cycle?A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the maximum of its time in what is referred to as interphase, where it grows, reproduces its chromosomes, along with prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
The cell cycle's longest phase is interphase. This is the stage at which the cell undergoes and duplicates its DNA before entering mitosis.
Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.
Thus, the cell growth takes place in the interphase of the cell cycle, and the division takes place in the M-phase.

The excretory system disposes waste through the stomach.
True or False?
Answer:
False.
Explanation:
Actually the stomach isn't part of the excretory system, it's part of the digestive system. The organs of the excretory system include the kidneys, large intestine, liver, skin, and lungs. The kidneys (also part of the urinary system) filter out blood from waste. The large intestine's job is to eliminate solid waste that remains after food is digested and water is extracted from the indigestible matter. The liver breaks down many substances in the blood, including toxins. Sweat glands in the skin secrete a fluid waste called sweat or perspiration; however, its primary functions are temperature control and pheromone release. The lungs (also in the respiratory system) excrete some waste products, such as carbon dioxide and water.

The mountains of the Sierra Nevada play a role in the formation of desert in eastern California and Nevada.
What is this an example of?
Answer:
The correct answer would be - The lithosphere influences the atmosphere and biosphere .
Explanation:
The mountains of the Sierra Nevada play the role of a barrier that blocks the air or wind that brings the clouds filled with water to eastern California and Nevada as it can not pass the mountains and reach the other side of mountains which cause less or no rain to this region.
Rain is a very important aspect for the region to be less diverse in plants and animals as most of them require water but as it is described there is no or very little precipitation so it becomes desert.
This makes it an example of the lithosphere influences the atmosphere and biosphere .
