Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.
Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.
A mutation is an alteration of the DNA sequence. Sometimes such alterations code for the same amino acid sequence as the unaltered DNA strand during protein synthesis. In such a circumstance, the mutation is not detectable. However, other mutations alter the genetic code in such a way that a noticeable change in the trait that is associated with that gene is visible. Sometimes such mutations are advantageous and improve the organism's ability to survive in its environment.
Natural selection is the process by which organisms with more advantageous traits (being camouflaged, being covered with the correct outer covering for the temperatures of that environment, stronger/ larger/ or faster to fight off or run from predators, etc.) are more likely to survive in a particular environment. Likewise, organisms less advantageous traits are more likely to die due to the pressures exerted by the environment (such as temperature, predators, illness, etc.). Therefore, the organisms with the advantageous traits that survive are more likely to survive to find a mate and reproduce. Thus, the advantageous traits are passed down to future generations.

Answer:
The king tide, also called a perigean spring tide, is caused by the sun and the moon aligning at just the right time such that the moon is closest to the Earth and the Earth is closest to the sun.
Explanation:
Explanation:
The mechanical advantage of a machine is the ratio of the load (the resistance overcome by a machine) to the effort (the force applied). There is no unit for mechanical advantages since the unit for both input and output forces cancel out.
Velocity ratio of simple machine is the ratio of distance travelled by the effort to the distance travelled by theload in the machine. As velocity ratio or ideal mechanical advantage is a simple ratio of two distances, it also does not have the unit. The friction is not involved in it.
Answer:
This is false as genes are transferred to a fetus from the reproductive cells(sperm, Egg cells)
Explanation:
This is because humans have 46 chromosomes, however this is comprised of the 23 chromosomes in each sperm and egg cells. This shows that genes are not transferred through the blood but by sperm and egg cells. Also genes and chromosomes are stored in the nucleus of cells, however red blood cells do not have a nucleus further showing that this is false.
