Using two heterozygous tall pea plants, so Tt is the genotype.

       T        t    <---- alleles from parent one

T      TT    Tt

t       Tt      tt

^alleles from parent two on the left

Results:  TT, Tt, Tt, and tt

Genotype ratio:  1/4 TT, 1/2 Tt, 1/4 tt

Phenotype ratio: T is dominant over t, so 3/4 tall and 1/4 short pea plants

Explain the statement “Scientific knowledge is the result of debate and conformation within the scientific community.”
spayn [35]

Answer:

What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way

Explanation:

Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.

When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.

The fossil record documents the existence, diversity, extinction, and change of many life forms throughout the history of life o
Marianna [84]

Answer:

Answered below.

Explanation:

The fossil records are beneficial in giving us. wide range of knowledge about fossils but sometimes these records are flawed, in that they are incomplete or misleading.

Many of the fossil records available are incomplete because some animals tend to decay within a short period of time due to their soft tissue. Also some are destroyed due to the movement of tectonic plates over time.

Another flaw scientists encounter is that there are no fossils which illustrate or represent the orderly transition from one organism to another. Fossils generally do not support the Darwinian theory of evolution as no evidence is found of ordered, sequential transition from simple to complex life forms as postulated.

These flaws are significant because they influence our knowledge and understanding of life forms and evolution.

What is the amino acid sequence for the mRNA strand CACCCAUGGUGA?
krek1111 [17]

Answer:

Histidine- Proline- Tryptophan- Stop codon

Explanation:

The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.

Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA

The following codons in the sequence specify the following amino acid:

CAC - Histidine

CCA - Proline

UGG - Tryptophan

UGA - Stop codon

Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.

N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.
