Sophie [7]

Answer:

Answer is D.Produce non-identical genetically different gametes and reduction of chromosomes,creating a haploid gamete.

Explanation:

Meiosis is essential for sexual reproduction.In humans diploid gamete-mother cells or germ line undergo meiosis to produce haploid gametes.

The chromosomes pairs of each parent undergo crossing over during meiosis.so daughter cells i.e gametes have genetic variations.When gametes  fuse and form zygote ,its genetic make up is different from both parents.thus meiosis allows a species to bring variations in next generations.Benenficial variations help organisms to adapt to the changes in environment.

Which two codons in the mRNA represent the amino acid phenylalanine
Trava [24]

Answer:

UUU and UUC

Explanation:

Information that encodes certain functional products called PROTEIN are present in the DNA molecule. However, the information needs to be expressed via the processes of transcription and translation. Transcription is the synthesis of a mRNA using a DNA template.

The mRNA then undergoes translation, where it is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid. Due to the degenerate nature of the genetic code, more than one codon can specify one amino acid.

Hence, in the case of phenylalanine amino acid, codons UUU and UUC both specify it. This means that whenever UUU and UUC are read during translation, a phenylalanine is added to the peptide chain.

Which of the following statements about chemiosmosis is NOT true?
melomori [17]

Answer:

I don't know the answer to the first one, but I can answer the second question. <em>Cellular respiration </em><u><em>has carbon dioxide and water as waste products</em></u><em>.</em>

Explanation:

<em>Cellular respiration</em> does <u>not</u> form glucose & oxygen and doesn't occur in the chloroplast, but does form <em>ATP energy</em>, <em>carbon dioxide</em>, & <em>water</em> and the process occurs in <em>mitochondria</em>. Photosynthesis on the other hand forms glucose & oxygen and does occur in the chloroplast.
