The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection? A)Directional selection



B)Stabilizing selection



C)Disruptive selection

Answers

Answer 1
Answer: The answer is B. Stabilizing selection. Stabilizing selection is a type of natural selection. Stabilizing selection is the opposite of disruptive selection where extreme values of a trait are favored over intermediate values.

Mammalian limbs are adapted for a variety of methods of food gathering. true or false

Answers

This is true. Mammals seem to have been thriving in the different environments around Earth. One good reason why this has happened has been because they are very well adapted to the challenges which their environment poses to them. With that said, this also means they are very good at gathering food for themselves which enables their survival.

Answers

Answer;

-Nuclei of gland cells.

Explanation;

-Enzymes are proteins that are manufactured in the ribosomes through the process of Translation. The process starts from the information contained in the DNA.

-First,  the information in a DNA molecule is read and transcribed it into an intermediary molecule called messenger ribonucleic acid, or mRNA, which takes place in the nuclei. Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are the building blocks of proteins, a process of translation which takes place in the cytoplasm in organelles called ribosomes.

B.) nuclei of gland cells

Explanation:

The paper clip, which is denser than water, floats on the surface because of water's surface tension. Surface tension is a property of water that is the result of polar water molecules sticking together or water's property ofA)
adhesion.
B)
cohesion.
C)
buoyancy.
D)
capillary action.

Answers

The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.

Answer:

The answer is cohesion.
