The role for the water test tube in each phase was that the water was used for comparison or control. In water we know there are no Macro-molecules, just water. Iodine is pretty dark but when you put it in the solution it <span>will change.</span><span />

How closely do Mendel insights into dominant and recessives traits match up with the ratios that punnett calculated in his Punne
elena-14-01-66 [18.8K]

Answer:

Perfectly in theory, except there is chance involved

Explanation:

The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.

However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.

However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.

vova2212 [387]

Answer:

Earthworms are Invertebrates and or soil Invertebrates

Explanation:

Remedial measures may be taken to promote beneficial organisms, thereby inhibiting the growth of destructive soil organisms...Can do so, because these soil invertebrates live their whole lives(most do) in the soil, adapted to, helping, and benefiting from the environment. Allowing them to act as . defenders for the soil.

Part a - bacterial cell wall peptidoglycan is a polymer of millions of n-acetylglucosamine (nag) and n-acetylmuramic acid (nam)
LekaFEV [45]
I believe the appropriate answer is, short amino acid chains, NAG, NAM, and some lipid proteins.
Peptidoglycan is also known as Murein, it is a polymer consisting of sugars and amino acids that form a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consist of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM),

Which statement best describes the relegation ship between proteins and nucleus acids
Novosadov [1.4K]

Answer:

The central dogma of molecular biology best describes the relationship between proteins and nucleic acid.

Explanation:

Nucleic acid such as DNA is the repository of genetic information in most organism.

          The genetic information stored in DNA is Transferred to RNA by transcription which deals with the the production of mRNA from DNA.

        The mRNA then undergo translation to transfer its own own genetic information in form of codons to specify amino acids of a protein molecule.

        Thus the Central dogma of molecular biology relates proteins and nucleic acids.
