As a general rule, the greatest vulnerability to _ occurs during the _ period of prenatal development.

1 answer:

Citrus2011 [14]3 years ago

6 0

The correct answer is letter A, thus the sentence goes:

As a general rule, the greatest vulnerability to EPIGENESIS occurs during the EMBRYONIC period of prenatal development.

This is a period in the prenatal development that epigenetic patterns and cell differentiation are intense, hence any factors that are found within the environment can ultimately alter the development of the organism.

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid

You read an article about vegetables grown in the United States. According to the article’s author, Americans need to take

Scorpion4ik [409]

Answer: Option D.

It is an evidence -based report.

Explanation:

An evidence based report is a report that is written based on scientific evidence to draw out conclusion or arguments for guidance and decision making for the people.

The article that was written, was base on some scientific proof that vegetables lack some nutrients. The vegetables have been analyzed and the constituents have been known. Conclusion was arrived at the Americans need to take dietary supplements to meet up with the daily nutrients requirements while taking vegetables.

According to appearances, which light produces the healthiest plant?

Dennis_Churaev [7]

Answer:

Blue light

Adding 10-20% blue light allowed plants to grow much healthier, with a compact appearance. There is also far-red light which is has wavelengths that are lower than normal red light–similar to near-infrared wavelengths. Far-red light helps the plants produce greater yields.
