Answer:
About 12.5%
Explanation:
Every half life usually eliminates about half or 50% of drugs that is stored in the body system.
Therefore, after one half life, the percentage of drug stored in the body will be 50%, after two half lives it will be reduced by 50% which is 25%.
After three half lives, the percentage of drug stored in the body will also be eliminated by 50% which will be half of 25% and it will be 12.5%.
Therefore, the answer is 12.5%.
leave absorb carbon dioxide from the air through
Answer:
Plant leaves have small openings, called stomata, all over their surfaces. The stomata open to absorb the carbon dioxide needed to perform photosynthesis. They also open to release the oxygen produced by this process.

or unbalanced?
Why?
Answer:
Unbalanced
Explanation:
I cant really explain this from the top of my head but i do know that if the forces were the same, the objects velocity will remain constant, but if the forces are unbalanced it will either slow down or speed up the objects velocity. an example would be tug of war i guess

Answer: analyze datawrite reports build models
Explanation:
How was genetic engineering able to solve the problem of tomatoes being damaged in transit without sacrificing taste?
What was the problem with this genetic engineering solution?
Answer:
The genetic engineering produced on these tomatoes was the solution to reduce the amount of chemical usage to crops as well as introducing a greater disease resistance, insect resistance, and increase shelf life. Conclusively, scientists and farmers still wanted to keep their natural color and flavor, yet change it into a more positive way. 70 years ago, spoke of the dangers of nightshade foods, covering all this ground, and stating that traditionally in South America, where potatoes and tomatoes come from they were eaten as medicine – that is given specifically for a short period time for a specific condition.

Explanation:
hat happens when humans burn fossil fuels? Carbon is released into the atmosphere. Carbon is removed from the atmosphere. Carbon is added to the the carbon cycle. Carbon is destroyed.
Answer:
Carbon is released into the atmosphere.
Explanation:
Carbon is released into the atmosphere. So, the correct option is (A).
What is Carbon?Carbon is defined as a chemical element, like hydrogen, oxygen, lead or any other element that is very abundant in the periodic table. It exists in pure or nearly pure forms such as diamond and graphite, but can also combine with other elements to form molecules.
Carbon is used in metal smelting in the form of charcoal (from wood) and coke (from coal) as impure carbon, which is particularly important in the iron and steel industries. Graphite is used in pencils, to make brushes in electric motors, and in furnace linings, while activated charcoal is used for purification and filtration.
When we burn we the human fossils, some gases like Carbon is released into the atmosphere.
Thus, Carbon is released into the atmosphere. So, the correct option is (A).

Which statement describes why hypotheses are valuable, even if incorrect? Select one: a. Adds to existing knowledge b. Answers a defined problem c. Allows theories to be proven d. Allows theories to be disproved A theory doesn't get disproved without large amounts of da
Answer:
The correct option is a: "Adds to existing knowledge"
Explanation:
A hypothesis is an idea that is brought forth based on an observation. It needs to be tested by carefully and thoroughly planning an experimental design that either supports or refutes the hypothesis. So even if it comes out to be incorrect, it still allows us to understand some aspect of a phenomenon that was unknown till then.
Human muscle cells are examples of what type of cells?
prokaryotic
eukaryotic
bacteria
plant
Answer:
Eukaryotic
Explanation:
Answer:
Eukaryotic cells
Explanation:
Human cells have organelles, and so do eukaryotes. Prokaryotes, on the other hand, do not have any organelles and can be seen in small microorganisms such as bacteria.
Plants is not an option becuse plant cells make photosynthesis and human cells (a type of animal cell) do not, as we are missing the chloroplasts necessary for photosynthesis.

What do all living cells have in common? 1. A cell membrane and genetic material 2.Chloroplast and mitochondria 3. A cell wall and cell membrane 4. A nucleus and genetic material
Answer:
one.
Explanation:
nuclei aren't present in prokaryotes, a cell wall/chloroplasts are a part of plants. the basic beings just need a cell membrane (to separate it from it's environment) genetic material, to get information to code proteins, and ribosomes, to create proteins.
All living cells have a cell membrane and genetic material. The correct option is 1.
A cell membrane, also known as the plasma membrane, is a fundamental feature of all living cells.
It is a thin, flexible barrier composed of lipids and proteins that surrounds the cell and separates its internal contents from the external environment. The cell membrane regulates the passage of molecules, ions, and other substances in and out of the cell, maintaining an internal environment necessary for cellular processes.Genetic material refers to the hereditary material that carries the genetic instructions for the functioning, development, and reproduction of living organisms.
In most cells, the genetic material is in the form of deoxyribonucleic acid (DNA).DNA contains genes, which are specific sequences of nucleotides that encode the information necessary to build and maintain an organism.All living cells have a cell membrane that serves as a boundary and a genetic material, usually in the form of DNA, that carries the instructions for the cell's functioning and inheritance. These two components are essential for the basic structure and processes of all living cells.
Thus, the correct option is 1, A cell membrane and genetic material.

How do particle speed relate to the distance between particles
Answer:However, particles will move in straight lines until they collide with something. Collisions usually change the speed and direction of the particles movements. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other.
Explanation:
Larger particles move slower, due to their larger mass and may be influenced by numerous collisions with many nearby smaller particles. Smaller particles move faster. ... Hotter particles move faster because they have more energy. The rate of diffusion increases as temperature increases because the particles move faster. You're welcome :) - xoxo madster

Which answer choice BEST supports the idea that the Scientific Revolution questioned the established ways that Europeans understood the world around them? A During this time, philosophers and thinkers in Asia, the Middle East, and Europe developed ideas and theories about how the Universe functioned, and then used mathematics to support their ideas. B This revolution was, in part, a response to the flood of new ideas pouring into Europe as a result of its expanded contacts with the rest of the world. C Europeans were able to collect and form new knowledge, and this led to Europe's unmatched power in the centuries that followed. D This way of thinking challenged the idea that the Bible was the source of all human knowledge, both historical and scientific.
Answer:
C. Europeans were able to collect and form new knowledge, and this led to Europe's unmatched power in the centuries that followed.
Explanation:
Scientific Revolution occurs in the Renaissance period in which the transition of Europe occurs from middle age towards modern era. This change occurs due to scientific revolution in the Europe. People at that time focus on obtaining knowledge and performing new research and experiments in order to obtain more knowledge and invent new technologies which make them powerful in the coming future.
