The answer is <span>They both suggest that snakes evolved from an ancestor with legs.
The second choice is not correct since we have no information about pythons and other snakes. We only have the relationship between geckos, snakes and legless eels. So, it is said that </span><span>snakes in general have more DNA sequences in common with four-legged geckos than they do with legless eels. This means that snakes are closer to geckos than the legless eels. We cannot conclude from this information which evolved from which, but we can say that </span><span>snakes evolved from an ancestor with legs.
In different case, if the snakes had more DNA sequence in common with legless eels, we would conclude that the snakes evolved from an ancestor without legs.</span>
Answer:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.

Answer:
Mass is how much matter an object has. like how much volume.
weight changes depending on gravity changes. your mass may be the same but you weigh differently in two places
Explanation:
The polysaccharides have been broken down.
Answer:
1/2 or 50%
Explanation:
The question involves a single gene coding for coat color in cattle. According to the question, the allele for red coat (R) is codominant to the allele for white coat (W). This means that neither of the two alleles are dominant nor recessive over one another, hence, they are both phenotypically expressed in their hybrid offspring (Roan coat, WR).
In a cross between two roan cattle (WR), each cattle will produce gametes with W and R alleles. Using these gametes in a punnet square (see attached image), a total of four possible offsprings will be produced with genotypes: RR, WR, WR, and WW.
RR (1/4) : Red coat
WR (1/2 or 2/4) : Roan coat
WW (1/4) : White coat
Based on this, the probability of producing an offspring that will be roan from the cross between two roan cattles is 2/4 equivalent to 1/2.
