The correct answer is option B, that is, all living organisms are composed of one or more cells, which came from pre-existing cells.
A scientific theory refers to a well-substantiated illustration of some characteristic of the natural world, on the basis of a number of facts, which have been repeatedly confirmed via the experiment and observation. Such fact-supported theories are not hypotheses, however, are reliable explanations of the real world.
During the late 1830s, the zoologist Schwann and the botanist Schleiden were examining tissues and postulated the unified cell theory. According to the unified cell theory, all the living things comprises of one or more cells, the cell is the fundamental unit of life, and the new cells originate from the pre-existing cells.
the right answer sense nobody can get it right is C (on the test) all living organisms are composed of pussss one or more cells duh.

what molecule is produced when two electrons and one proton are added to NADP+
The molecule produced is NADPH.
Explanation:The molecule produced In biochemical reactions, NADP+ acts as a "hydride" acceptor.
The hydride is not H-, but its chemical equivalent, H++2e-
The hydrogen atom adds to the nicotinamide ring, converting the molecule to NADPH.
by adding two electrons and one proton to NADP plus is NADPH.
When two electrons and one proton are added to NADP+, the molecule NADPH is produced. NADPH is a coenzyme that functions as an electron carrier, playing a critical role in the biosynthetic and energy-producing processes within cells.
The reduction of NADP+ to NADPH involves the addition of two high-energy electrons and one proton (H+). This reduction is a key reaction in photosynthesis occurring in the light cycle, as well as in other biochemical pathways. The two electrons added to NADP+ neutralize its positive charge, while the addition of the proton contributes to the formation of NADPH. This high-energy molecule carries the electrons that are required for the synthesis of various biomolecules and aids in the conversion of energy within the cell. The NADPH generated is then used in the Calvin cycle to assimilate carbon dioxide into organic compounds, as well as in other biosynthetic processes.
If there is a higher concentration of water outside of the cell
Water will move into the cell
water will move out of the cell
water will not move
water will move equally into and out of the cell
i believe in that situation water would move into the cell
even in a fully grown adult, cell still undergo cell division why is this useful
Think about skin cells. Skin cells shed every day, if cell division didn't take place, you would just constantly be losing skin cells.

Hello!
For background the plant shown is an orchid. Generally, purple is the dominant color and trait within this species and white the recessive allele.
If we use Mendell's Punnett Square we can actually see that together the pair are codominant with one another.
So the answer to your question would be, c. codominant with the allele for the white flower color.
If only one particular color was showing, we could say that one was dominant over the other. However, due to the fact that both traits show, that means they are codominant ! As recessive genes will not show under the presence of a dominant gene.
Hope this helps answer your question!

diffusion continues until the concentration on both sides of the membrane is
I don't understand it
Diffusion is the process in which movement of molecules , ions, and atoms take place from region of higher concnetration to low concentration. This diffusion will continues till both side of membrane is equal, because it is the movement of molecule from high to low concentration, so once its became equal concnetration diffusion will not take place.
Diffusion is the process where particles move from an area of higher concentration to an area of lower concentration. It continues until there's equal concentration on both sides of a membrane. This principle applies to particle movement in biological organisms and is important for cellular equilibrium and energy conservation.
Explanation:Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until there is equal concentration on both sides of a membrane. This process occurs in living organisms and it's a way for cells to maintain equilibrium, while trying to conserve energy. In essence, diffusion continues until the concentration on both sides of the membrane is equal.
An everyday example of diffusion is when perfume is sprayed in a room. At first, the scent is strongest near the source, but over time it spreads out evenly across the room. The same principle applies for particle movement across a cell membrane in a biological context.

Which statements describe Newton and the law of universal gravitation? Check all that apply
Newton's Universal Law of Gravitation states that each particle in the universe attracts every other particle with a force that is directly proportional to their masses and inversely proportional to the distance squared between them. Newton's formulation is essential for understanding gravitational forces in classical physics and is foundational for calculating planetary orbits and terrestrial gravity.
Understanding Newton's Law of Universal Gravitation
Sir Isaac Newton formulated the Universal Law of Gravitation, which revolutionized our understanding of how objects in the universe interact through gravity. This law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses. This gravitational force is also inversely proportional to the square of the distance between the particles.
The formula for Newton's universal law of gravitation can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two particles, and r is the distance between them. This law has been key to understanding celestial mechanics and is a cornerstone of classical physics. It is also the fundamental principle understanding the orbits of planets and the behavior of objects under the influence of gravity on Earth.
However, it's important to recognize that Newton's law was later supplemented by Einstein's theory of general relativity, which gives an even more accurate description of gravitational phenomena, especially near very massive objects or at very high velocities. Nonetheless, Newton's law of universal gravitation remains a crucial tool for common gravitational calculations in everyday situations where general relativity has negligible impact.
