B
Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.
Answer: Population distributions may be described as <em>random, uniform</em><em> or </em><em>clustered.</em>
Explanation:
In a specified region, a population comprises any number of members of the same species. Populations are described by sizes- the number of individuals; densities- individuals in a set space (per unit area); and distribution- the dispersal or non dispersal of individuals (spread out or clumped). Population distributions may be described in three ways:
- Random: the distribution pattern is haphazard, with no regular spacing; individuals grow independently of each other without competing and resources are consistent. <em>E.g. dandelion seed dispersal by wind </em>
- Uniform: individuals are evenly spaced in a predictable pattern; there may be some interaction and ideally, spaces between them are maximized in order to ensure access to limited nutrients and resources.<em> E.g. human farming- cornfields, orchards; allelopathy in plants like purple sage, which secretes chemicals to prevent the growth of other plants nearby</em>
- Clumped: there is less distance between neighboring organisms and these individuals cluster together. This pattern is most common in environments where resources are scarce, or the species is dependent on social interactions.<em> E.g. lions are highly social and hunt in prides in the wild</em>
Answer:
adding a catalyst
Explanation:
catalysts accelerate the speed of chemical reactions
Answer:
Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed.
Explanation:
Answer:
muscle contraction increases interstitial fluid pressure and compresses the blood vessels within the active muscle. As a consequence, blood flow is highest when muscles relax between successive muscle contractions.
