Explain how ions, such as phosphate ions, are absorbed by plant roots.
Answers
Answer:
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption
Explanation:
....
Phosphate ions are absorbed by plant roots through the process of active transport, which requires energy and specialized transport proteins.
What is active transport?Plant roots absorb ions such as phosphate ions through a process called active transport. Active transport is the movement of ions or other molecules across a cell membrane against their concentration gradient, from an area of low concentration to an area of high concentration, which requires energy in the form of ATP.
To absorb phosphate ions, plant roots use specialized membrane proteins called phosphate transporters, which are located in the plasma membrane of root cells. These transporters actively pump the phosphate ions from the soil into the root cells, using the energy from ATP hydrolysis. The phosphate ions can then be transported throughout the plant via the xylem vessels and used for various biological processes, such as DNA and RNA synthesis and energy storage.

How many times longer is DNA than it is wide?
Answers
Answer:
About 200 km 7.
DNA is approximately six times longer than it is wide after measurements.
DNA is a 2-nanometer-diameter double-stranded molecule. Rise per base pair is 0.34 nanometers. Divide length by width to calculate length-to-width ratio. The length-to-width ratio is 6:1 due to DNA's stable diameter and base pair distance. DNA is six times longer than broad.
DNA stores and encodes genetic information efficiently in this elongated shape. DNA molecules can range from a few hundred base pairs in bacterial genomes to millions or billions in sophisticated animals. DNA stores and transmits life's genetic blueprints because it's longer than it is wide.

Why do we need friction in our world?
Answers
Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.
Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. While walking, you're pushing your foot back as you try to step forward. Friction holds your shoe to the ground so you can walk around.

Which reservoir is found underground in the cracks and spaces in the soil, sand, and rock?
A) Glaciers
B) Ground water
C) Polar ice caps
D) Rivers
Explain Why
Answers
Explanation: first of all, it is in the name. Ground water is water that is found in the ground. Another idea to find the answer would be to do process of elimination.
A glacier is a moving mass or river of ice that is mainly found in Antarctica and Greenland. Polar ice caps are regions that are covered in ice. A river is a natural flowing source of water that flows towards an ocean, sea, lake or another river. Ground water is water located beneath the Earth’s surface and can be found in cracks and rock formations. By doing process of elimination, you can easily cross out the possibility that the answer is glaciers or polar ice caps because they both have something to do with ice. This leaves you with rivers and ground water. You can eliminate rivers because rivers can’t fit into cracks and spaces in the soil. This leaves you with your answer of ground water.

Why do some electromagnetic waves have more energy than others?
Answers
Answer:
For electromagnetic waves, speed is constant, so waves with a high frequency and a short wavelength (like X-rays) are the most energetic. For all waves, a greater amplitude means more energy
Explanation:
Gamma rays have the maximum energy on the electromagnetic spectrum, while long radio waves have the lowest. In addition to visible light, the sun also radiates infrared (IR) and ultraviolet (UV) energy. A narrow range of wavelengths, from 380 nm to 750 nm, are covered by the visible portion of the electromagnetic spectrum.
What about electromagnetic waves?The electric field will change as the magnetic field changes, and vice versa.Electromagnetic waves, as opposed to mechanical waves, can move across empty space.From highest to lowest energy, the components of the electromagnetic spectrum are referred to as gamma rays, X-rays, UV radiation, visible light, infrared radiation, and radio waves. Electromagnetic waves, which have varying wavelengths from one another, include radio waves, microwaves, visible light, and x-rays. The wavelengths are (a) longer; (b) shorter.All electromagnetic waves are transverse waves that can pass through a vacuum and travel at the same speed—300,000,000 times the speed of light—while doing so.The longest wavelengths are found in gamma rays. The electromagnetic spectrum's greatest frequency is found in gamma rays. They oscillate between 1020 and 1022 HzGamma Rays are the right response.Learn more about electromagnetic waves here:
