Other than the modern horse, what was important of the evolution of an organism?
Marat540 [252]

Answer:

Evolution is considered a way in which past generations were able to adapt to the difficulties and changes that the world around them imposed, from the need to seek food to survival in the face of different climatic and landscape changes, becoming stronger and therefore allowing the enduring and transcendence of it.

Explanation:

The importance of evolutionary studies is very large, since all organisms and their characteristics are products of evolution. It has an enormous interest applied in topics such as biodiversity conservation, medicine, agriculture, livestock, etc. Evolutionary biology is concerned with understanding the processes that have given rise to the current characteristics of organisms, and explaining why the characteristics of those organisms are what they are and not different ones.

10. Cloud droplets form and grow as water vapor condenses onto hygro-
Natali [406]

Answer:

According to collision- coalescence theory, formation of raindrop from cloud droplets occurs when cloud droplets collide and coalesce or stick together.

Explanation:

  • The only significant difference between a raindrop and a cloud droplet is that a raindrop consist of a velocity that is non-negligible during the fall.
  • Larger droplets having higher terminal velocities fall faster and collide with smaller droplets. Often the cloud droplets stick together and coalesce to form a larger droplet.
  • This starts a chain reaction where these bigger droplets fall even rapidly, collide with the other droplets in their path and merge with these droplets.

Mutations in DNA include deletions and insertions. These types of mutations:
pantera1 [17]

Answer:

(A). Result in different amino acids to be read due to frame shifts

Explanation:

Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.  

These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.

This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.

Thus, the correct answer is option (A).
