If dna is colorless when dissolved in water, how were you able to see the dna after it ran through the gel?.

Answers

Answer 1

Answer:

To visualise the DNA, the gel is stained with a fluorescent dye that binds to the DNA, and is placed on an ultraviolet transilluminator which will show up the stained DNA as bright bands. Alternatively the dye can be mixed with the gel before it is poured

how can one eukaryotic gene lead to one transcript, but multiple different proteins?

Answers

Answer:

source- The ability of certain genes to form multiple proteins by joining different exon segments in the primary trans-cript is called alternate splicing and has caused a reexamination of the concept of “one gene, one protein.

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. ... Human genes typically contain several "exons," or DNA sequences that code for amino acids, the building blocks of proteins.

in your own words-

the flexibility of bound factors to make multiple proteins by connection totally different DNA segments within the primary trans-cript is termed alternate junction and has caused a reexamination of the thought of “one gene, one macromolecule.

Scientists have long noted that it's attainable for one factor to provide slightly totally different styles of a similar macromolecule by skipping or together with bound sequences from the informational RNA. ... Human genes usually contain many "exons," or desoxyribonucleic acid sequences that code for amino acids, the building blocks of proteins.

Answers

Answer: T1-T11; two adjacent ribs

Explanation:

The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.

What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.

Because sweat is a feedback system to maintain homeostasis in the body to keep the temperature normal—if elevated for too long it will denature enzymes in the body, cause organ damage, etc. so it is needed to cool the body during exercise. Urination maintains chemical balance in the body to remove wastes, but that will not help the body keep cool during exercise.

1. What happened to the pH of the substances when the size of the sample was increased or
decreased?

2. What happened to the pH when the sample was diluted? Did the material change from its original classification as an acid/base/ or neutral?

3. Describe a neutralizing reaction and give the neutral products?

4. Predict the general pH that is the result of combining a strong acid with a weak base?

Answers

Explanation:

An acid-base reaction or neutralization reaction is a chemical reaction that occurs between an acid, for example hydrochloric acid, and a base, sodium hydroxide.

The word "salt" describes any ionic compound whose cation comes from a base (Na + from NaOH) and whose anion comes from an acid (Cl- from HCl). Neutralization reactions are generally exothermic, which means that they give off energy in the form of heat. They are often called neutralization because when an acid reacts with a base, they neutralize each other's properties.

There are several concepts that provide alternative definitions for the reaction mechanisms involved in these reactions, and their application to related problems in solution. The word neutralization can be interpreted as annihilation or as elimination, which is not far from the truth. When an acid is mixed with a base both species react to different degrees that depend largely on the concentrations and volumes of the acid and the base can be considered as an illustration the reaction of a strong acid that is mixed with a weak base, this The latter will be completely neutralized, while a portion of the strong acid will remain in solution, depending on the moles that reacted with the base. Three additional alternatives that arise from mixing an acid with a base can be considered:

A strong acid is mixed with a strong base: When this happens, the species that will remain in solution will be the one that is in greater quantity than the other.A weak acid is mixed with a strong base: The solution will be basic, since it will be the base that remains in the reaction.A weak acid is mixed with a weak base: If this happens, the acidity of a solution will depend on the acid constant of the weak acid and the concentrations of both the base and the acid.Despite the differences in definitions, its importance is evident in the different methods of analysis, when applied to acid-base reactions of gaseous or liquid species, or when the acidic or basic character may be somewhat less evident. The first of these scientific concepts of acids and bases was provided by the father of chemistry, the Frenchman Antoine Lavoisier, around 1776.

pathogens are the biological agent that can cause a disease in another organism upon infecting and causes infectious diseases. ‘Pathogen’ is a or disease-causing organisms such as bacteria, viruses, fungi, protozoans and worms.

There are different types of pathogens such as Class 1 pathogen in which the species is not associated with infectious disease. Class 2 are the pathogen species cause disease in humans but not serious and the the preventive methods, treatments are available.

Class 3 pathogens include the species cause serious diseases in humans, but necessary prophylaxis and treatment are available; Class 4 pathogens include the species cause serious human disease and disseminate in the human population with  no adequate prophylaxis or therapy exists.

Why do parrots mimic people?

Answers

Answer:

Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.

Explanation:

Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.
