Answer:
Isotonic Solution
Explanation:
There are commonly three types of solutions:
- Hypertonic solution = the concentration of solute is greater than in the cell
- Hypotonic solution = the concentration of solute is less than in the cell
- Isotonic solution= the concentration of solution and cell is same.
So, if the cell was in any other solution, it would have been burst or it would shrink. but nothing changed because it was in a solution where outside environment is similar to the internal environment
Answer: CARBON DATING
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years.
Answer:
two strands of nucleotides
Explanation:
nucleotides are made up of suger, a phosphate, and a nitrogen base The sugars and phosphates make up the ''handrails'' or ''backbone'' however you wanna say it and they are held together by covalent bonds.
Answer:
1.The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.
2. As the combustible materials burn, some of the chemical energy is transformed into heat energy, and some is transformed into light energy. Light energy, also known as radiation or electromagnetic energy, is a type of kinetic energy that takes the form of visible light waves, such as the light from a match
3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
4. Answer: Refraction is the bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms, and rainbows. Explanation: Refraction.
5. The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
Answer:
An axis is an invisible line about which an object rotates, or spins.
