<span> b. Stabilizing selection. In stabilizing selection, the average trait in the population is more favored</span>. In this case, the average leg muscle is favored over heavier and lighter because it can benefit Siberian Husky's role more.
If the plasma membrane were made of a hydrophilic substance like carbohydrate The cell would disintegrate very quickly.
- The tails, which face the inside of the cell membrane, are "hydrophobic," but the heads, which make up the exterior and inner linings, are "hydrophilic" (water loving) (water fearing).
- Water is drawn to the membrane's exterior (red) and inside (yellow), but cannot pass through the non-polar layer.
- They are insoluble in water like all lipids, but due to their special geometry, they may form bilayers without the usage of energy.
- They have hydrophilic (water-loving) phosphate heads and hydrophobic (water-fearing) hydrocarbon tails made of fatty acids, making them two-faced molecules.
- Phospholipids, which are made up primarily of fatty acids and alcohol, make up the majority of the plasma membrane.
- The plasma membrane's phospholipids are organized into two layers, known as phospholipid bilayers.

Answer: Gravitational lensing
Explanation: The arc that was seen around the galaxy by the scientist was caused by gravitational lensing; this is when a light dip and curves in the presence of huge objects.
Gravitational lensing can be simply refered to as a phenomenon where a gravitational field is created by a huge matter (cluster of galaxies) in space which distort and magnifies the lights coming from another huge matter (cluster of galaxies) from a distance but on thesame line of sight. (causing a formation of arcs of light around the huge object).

Bacteria are single celled microorganisms. They have a simple cell structure than other organisms because they have no nucleus and no cell membrane. Their control center containing the genetic information si contained in a single loop of DNA. They are classified into five groups according to their shape; cocci are spherical, bacilli are rod shaped, spirilla are spiral, vibrios are comma and spirochaetes are corkscrew. They can exist as singe cells in pairs, chains or clusters. Rod shaped bacteria are called bacilli.
