Given what we know, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

This has to do with a phenomenon known as the doppler effect. This effect explains how we can perceive a star as red or blue depending on its distance and on whether or not it's moving towards or away from us. When an object moves away from us, the wavelengths of the light it emits are stretched, making the object appear red. However, when it moves towards us, this increases the wave frequency that reaches us and we observe it as blue.

Therefore, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

Answer:

The central components of the cell-cycle control system are cyclin-dependent protein kinases (Cdks), whose activity depends on association with regulatory subunits called cyclins. Oscillations in the activities of various cyclin-Cdk complexes leads to the initiation of various cell-cycle events.

Biotechnology is a branch of science that deals with technology by utilizes biological systems, living organisms, or parts of this to develop or create products with the goal of human welfare.

During brewing and baking bread yeast are used to produce alcohol are examples of processes that fall within the concept of biotechnology, Genetically modified orgnisms and crops are also product of the biotechnology. The insulin production also an example of this process.

People consider use of biotechnology unethical to produce genetically modified organisms or crops and cloning is considered as against the law of nature.

All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation

Everything needs to be sterile

All instruments need to be inspected for any signs of contamination after the sterilisation process

Shoes from outside should never be worn inside an operating room

Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment

The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids

Answer:

This could result in a mutation.

Explanation:

A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.

16 amino acids could be specified if codons consisted of two nucleotides instead of three.

Codons may be defined as an arrangement of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid.

A mutation may be responsible for such problems that would present for an organism making proteins using all 20 amino acids.

A synonymous mutation means that one base within the codon gets substituted for another. Even though the same amino acid is still produced.  

It changes the sequences of nucleotide bases within the codon, but ultimately the coded amino acids remain the same.

Therefore, it is well described above.

Answer and Explanation:

Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.

There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.

Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.

Answer:

1 Zinc, 2, Hydrogen, 2 Chlorine

Explanation:

Zinc, 2, Hydrogen, 2 Chlorine is a chemical reaction.

Chemical reaction, the transformation of one or more chemicals (the reactants) into one or more distinct compounds (the products). Chemical elements or chemical compounds make up substances.

Chemical reactions are a fundamental component of life itself, as well as technology and culture. Burning fuels, smelting iron, creating glass and pottery, brewing beer, making wine, and making cheese are just a few examples of ancient processes that involved chemical reactions.

The Earth's geology, the atmosphere, the oceans, and a wide variety of intricate processes that take place in all living systems are rife with chemical reactions.

Therefore, Zinc, 2, Hydrogen, 2 Chlorine is a chemical reaction.
