Answers

Answer:

How would you  contained protein ​

Explanation:

One would test a sample of powdered milk to see if it contained protein ​by using copper sulfate solution and  sodium hydroxide solution.

What is protein?

A structure composed of amino acids. The body need proteins to function properly. They serve as the building blocks for several bodily components, including the skin, hair, and enzymes, cytokines, and antibodies.

An essential component of a balanced diet is protein. Amino acids are the chemical "building blocks" that make up proteins.

Amino acids are used by your body to create hormones, enzymes, and to build and repair muscles and bones. They can be utilized as a source of energy as well.

The test can be done as:

To your meal solution, add a few drops of copper sulfate solution. A few drops of sodium hydroxide solution should be added. Protein is present in the food if the solution becomes purple.

Thus, using copper sulfate solution and sodium hydroxide test, one can determine the protein content in the sample.

What is Entomology ?

Entomology is defined as the investigation of insects and how they interact with people, the environment, and other living things. Entomology is employed extensively in a wide range of fields, including evolutionary biology and medical research, in addition to studying the anatomy and physiology of insects. It aids agricultural entomologists in their research on biodiversity as well as in the protection of priceless resources from insect pests.

Forensic entomology is defined as the study of arthropods, particularly insects, connected to criminal activity and other judicial issues. An essential tool in the examination of homicide, self harm, and other violent crimes is forensic entomology. When properly gathered and examined by skilled forensic investigators, insect evidence found on a victim's corpse can provide important information.

Thus, a person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.

The role of the RNA-induced silencing complex (RISC) in RNA interference is to cleave tRNAs to slow the rate of translation. disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced. cleave the introduced RNA duplex. disrupt gene expression by interfering with mRNA export to the cytoplasm. create a passenger strand to bind to the mRNA and keep the mRNA from being translated.

Answers

Answer:

disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced

Explanation:

The RNA-induced silencing complex (RISC) is a ribonucleoprotein complex composed of proteins that associate with regulatory small non-coding RNAs (sncRNAs) such as, for example, microRNAs (miRNAs) and small interfering RNAs (siRNAs) in order to regulate gene expression by the RNA interference (RNAi) pathway. These sncRNAs (around 18-30 nucleotides in length) are complementary or nearly complementary to messenger RNAs, thereby they can bind to target mRNA sequences in order to trigger RNAi via mRNA degradation, translational repression, etc. The core component of the RISC complex is an evolutionary conserved Argonaute (Ago) protein that cleaves target mRNAs.

The C7 spinal nerve exits on each side through the intervertebral foramen between the C6 and C7 vertebrae. The C7 spinal nerve has both a sensory root which is composed of sensory fibers and a motor root. This nerve is required to control motor functions including shoulder movement (i.e., adduction, abduction and rotation). The C7 dermatome is a region of skin that receives sensory inputs from the C7 spinal nerve.
