Yes, a PH of 7 is considered neutral.
madreJ [45]2 years ago

Answer:

True.

Explanation:

An acidic solution may be defined as the solution that has more concentration of hydrogen ions and pH of the solution is less than seven. Basic solution contains more hydroxide ions and pH is above seven.

The neutral substance may be defined as the substance that has equal concentration of hydrogen and hydroxide ions in the solution. The neutral substance can be formed by the mixing of acidic and basic solution. The neutral solution has pH equal to the seven.

Thus, the answer is true.

Recall that DNA and RNA are synthesized only in the 5'→3' direction and that DNA and RNA sequences are written in the 5'→3' dire
aleksley [76]

Answer:

<u>The Transcription mRNA</u>

5'- AUG-CCC-GUU-UGG-AGA-UCG-GGU-UAC-AGC-UAG-3'

<u>The translation product</u>

5' Met-Pro-Val-Trp-Arg-Ser-Gly-Tyr-Ser-3'

Explanation:

Transcription is a process which transcripts the DNA to a molecule called mRNA or messenger RNA which contains code for the synthesis of amino acids.

The RNA nucleotide base pairs are added in the same way as in the DNA that is guanine will bind cytosine but adenine will bind uracil instead of thymine.

Since the start codon is AUG which codes for methionine and stop codons could be UAG, UAA or UGA which do not code for the amino acids during translation.

In the given question,  

Looking for the start codon which is AUG in the template strand is found and the transcript mRNA thus will be coded as

<u>Template strand</u>

3' AACTT-TACGGGCAAACCTCTAGCCCAATGTCGATCAGTTTC 5'

<u>The Transcription mRNA</u>

5'- AUG-CCC-GUU-UGG-AGA-UCG-GGU-UAC-AGC-UAG-3'

<u>The translation product</u>

5' Met-Pro-Val-Trp-Arg-Ser-Gly-Tyr-Ser-3'

Guess what percent of your DNA is the same as the following organisms.A weed? % the same as meA fruit fly? % the same as meA mou
kirill [66]

Answer:

The correct answer will be-

1. Weed- 40%

2. Fruit fly- 60 %

3. Mice- 97.5 %

4. Chimpanzee-98.5 %

Explanation:

Charles Darwin suggested that all organism on earth have descended from a common ancestor.  The modern technology-enabled humans to sequence the genome of an organism and compared them with each other.

When the human genome was compared with the genome of other organism found the similar sequences in them like - Weed shared 40% of the genome with humans, fruit fly shared 60% genome, mice showed 97.5% genome similarity and chimpanzees showed 98.5 % with the human genome.

On the basis of this, the chimpanzee was found to be the closest species to humans

In a cross between pure-breeding tall plants with pure-breeding short plants, all of the F1 are tall. When these plants are allo
Sindrei [870]

Answer:

d. The tall and short traits assort independently of each other in this cross.

Explanation:

In the given example, the alleles for tallness and shortness of the plant belong to the same gene. The dominant allele “T” makes the plants tall while the recessive allele “t” is responsible for short plants. During gamete formation, independent assortment segregates the alleles of two different genes randomly. This process produces some new allele combinations in the progeny. However, the process of independent assortment is not about the segregation of alleles of a single gene from each other.
