A complete collection of single-use and high-throughput electrocompetent and chemically competent E. coli
Choosing the ideal competent cells for your cloning applications and workflows is a critical component of success. Aspects to consider when selecting your competent E. coli strain include:
Transfection method – chemical versus electroporation
Transformation efficiency – bacterial strain and genotype
Downstream application – protein expression, library production, general cloning
<span>The vast majority of organisms within the kingdom animalia are the invertebrates and the vertebrates. These include organisms that have the ability to ingest food and movement for defense and attack. Humans are one of the organisms in the Kingdom Animalia. Hope this answer helps.</span>
Answer:
C
Explanation:
Air flowing from areas of high pressure to low pressure creates winds. Warm air can hold more moisture than cold air. Air moving at the bases of the three major convection cells in each hemisphere north and south of the equator creates the global wind belts.
The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
Temperature, moisture and sunlight are abiotic factors that make up the climate of a terrestrial biome.
<h3>What are abiotic factors?</h3>
Abiotic factors are environmental conditions that form the ecosystem together biotic (life) factors.
Abiotic factors are variable according to the type of biome and they are fundamental to sustaining life.
In conclusion, temperature, moisture and sunlight are abiotic factors of a terrestrial biome.
