WHAT problem was the electric toothbrush supposed to solve?
Answer:
Brushing too hard can erode the enamel on your teeth and cause gum recession. Many electric toothbrushes can solve this problem, too. They have pressure sensors that warn you if you're pressing too hard. That way, you can develop a proper touch that will remove plaque, but not damage your teeth and gums.
Explanation:
Electric toothbrush bristles vibrate or rotate to help you remove plaque buildup from your teeth and gums. The vibration allows for more micro-movements every time you move your toothbrush across your teeth

The biodiversity of cultivated crops is currently under threat from industrial
farming and climate change. The extinction of important crop plants
cause mass starvation. Which of the following is the best way for humans to could
use a seed bank to help prevent this problem?
• A. By
storing a great variety of seeds in case one variety goês
in the wild
extinct
• B. By storing a large number of seeds that can be eaten when famine
occurs
• C. By growing a large quantity of crops from seed and selling the
food they produce
• D. By growing a large quantity of
food they produce
crops from seed and storing the food they produced
The best way for humans to use a seed bank to help prevent the threat to biodiversity of cultivated crops is by storing a great variety of seeds in case one variety goes in the wild extinct.
What is biodiversity?
Biodiversity refers to the variety of life forms that exist on Earth, including the different species of plants, animals, fungi, and microorganisms, as well as the genetic diversity within each species, and the diversity of ecosystems and biomes. Biodiversity is important because it supports the basic ecological processes that sustain life on Earth, such as photosynthesis, nutrient cycling, and pollination. It also provides us with a wide range of ecosystem services, such as clean air and water, food, medicine, and cultural and recreational opportunities.
The best way for humans to use a seed bank to help prevent the threat to biodiversity of cultivated crops is option A, which involves storing a great variety of seeds in case one variety goes extinct in the wild. This approach is important because it helps to preserve the genetic diversity of crop plants, which is essential for breeding new varieties that can withstand changing climate conditions and resist diseases and pests. Storing seeds in a seed bank provides a backup in case a particular crop variety becomes extinct in the wild. It is a cost-effective way to protect the genetic diversity of crop plants and can serve as a long-term solution to the problem of food insecurity.
Option B, storing a large number of seeds that can be eaten when famine occurs, may provide short-term relief during a food crisis, but it does not address the root cause of the problem, which is the loss of biodiversity in cultivated crops. Option C, growing a large quantity of crops from seed and selling the food they produce, and option D, growing a large quantity of crops from seed and storing the food they produced, are both important for food production, but they do not directly address the problem of biodiversity loss in cultivated crops.

Water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
What do you mean by Proximal tubule?A Proximal tubule may be defined as the portion of the nephron that lies in between Bowman's capsule and the loop of Henle.
The major function of the proximal tubule is to reabsorption of sugar, sodium, chloride ions, and water from the glomerular filtrate. It decreases the volume of tubular fluid.
Therefore, water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
