Answer: C). The protein formed from the mutated strand will be the same as the protein formed from the original strand.

Explanation: The two protons have the same amino acid sequence therefore, the mutated protein is the same with the protein formed from the original strand. This is because the two codons AAA and AAG codes for the amino acid lysine. A phenomenon whereby an amino acid is specified by more than one codon is known as degeneracy. This does not mean that the genetic code is flawed but each codon specifies only one amino acid. The degeneracy of the codes are not uniform, some amino acids are specified by one codon, while some are specified by more than one codons. For example, methionine and tryptophan have single codons, Leucine, serine and arginine have six codons, isoleucine has three codons, alanine, glycine, and threonine have four codons.

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
LuckyWell [14K]

Answer:

As a transcription factor

Explanation:

Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.

The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.

The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.  

Thus, as a transcription factor is correct.

Which scenario describes a way that an abiotic factor can impact a marine system? Liquid water turning into solid ice encourages
Sloan [31]

Answer:

Rapid increases in water temperature cause extensive fish kills

Explanation:

Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.

Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.

Which of the following structures is most likely to be found in an autotrophic protist?
GenaCL600 [577]

The right answer is the chloroplast.

Autotrophic species must stock up on food in order to have energy at all times.

Plants, for example, through their chloroplasts make sugar with the energy of sunlight and from soil water and carbon dioxide from the air. This sugar synthesis using light is photosynthesis.
