Changes in the gene pool can occur due to various mechanisms. In 1989, a large oil spill occurred in Prince William Sound, Alaska, when the Exxon Valdez oil tanker ran aground. Approximately 11 million gallons of oil were spilled and spread 1,300 miles along the Alaskan coastline. The damage from the oil spill affected thousands of animals in the area, including killer whales, harbor seals, sea otters, fish, and sea birds. Which mechanism most likely affected the gene pools of the organism populations in the areas around the oil spill?

Answer:

Hydrophobic molecules don't like water,just like the membrane.Since the membrane and these signaling molecules are made of the same thing,liquid,they can easily mix together.

Explanation:

Hydrophobic signalling molecules move right through the cell membrane to the target inside the cell.

Answer: B

Explanation:

The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce amino acids.

Final answer:

Differences observed in the plant groups would most likely be due to their differing abilities to produce glucose, a monomer that forms cellulose and other sugars vital for plant functions. Other options such as amino acids, cellulose and DNA also play crucial roles in the plant's life processes.

Explanation:

The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce glucose. Glucose is a monosaccharide, or a simple sugar, that serves as the primary fuel for plants. Glucose monomers form structures like cellulose, which primarily make up a plant's cell wall, providing it with structural support. Glucose is also involved in the formation of other types of sugars such as sucrose and lactose when combined with fructose and galactose, respectively.

However, it's important to note that all the options given - glucose, amino acids, cellulose, and DNA - are monomers or polymers that play vital roles in the life functions of a plant. Amino acids are the building blocks of proteins, cellulose is a structural polysaccharide composed of glucose units, and DNA holds the genetic information of the plant.

The Answer for that question is True.

Answer:

Finding time to exercise can be difficult, but it is important to consider time spent exercising as important time, as important as social commitments, work, and school. Therefore, effective strategies to increase time for exercise include scheduling blocks of exercise time, making people more aware of your exercise time, analyzing your schedule for the best time to exercise, pursuing activities that can be done from home, finding places to exercise that are close to home, work, or school, and finding a person with whom you can exercise.
