The evolution of molecular biology has made possible to establish a new classification of all organisms according to their DNA, and it's called phylogenetic classification.This classification groups living beings according to their kinship, established according to anatomical, physiological and behavioral criteria and especially genetic, based on the similarity of genes between species.
This made it possible to discover kinship ties between species of which there is no suspicion of any morphological link between them, something which the old classification (the traditional classification) was incapable of doing (and this proves the importance of the DNA and genes in organisms classification.

Answer:
True
Explanation:
Muscle contraction. It refers to the physiological process during which the muscle, by sliding of the structures that compose it; It shortens or relaxes. Its functioning is closely related to the structure of the muscle fiber and the transmission of the electrical potential through the nerve pathways. The model that describes muscle contraction is known as a filament slip mechanism.
Small projections that originate on the sides of myosin filaments are called cross bridges, the interaction between these cross bridges and actin filaments causes contraction.
When there is an increase in the total mass of a muscle it is called muscular hypertrophy. When it decreases The process is called muscular atrophy.
When the frequency reaches a critical level, the successive contractions finally become so rapid that they merge with each other and the contraction of the entire muscle appears to be completely smooth and continuous so <u>weaker contractions</u>.
Climate is the long-term average weather conditions that occur in a particular region. Climate depends on how average weather conditions change throughout the year.
Answer:
If you have thick blood, you're at greater risks for blood clots, both in your veins and arteries. Blood clots in your veins will impact blood flow to key areas of your body.
