Answer:
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells and makeup the genetic material. Nucleic acids are found in abundance in all living things, where they create, encode, and then store information of every living cell of every life-form on Earth.
q.no. 5 answer me please please please please please please please please please please please
Answer:
(a)The strength of natural fibers is very less as compared to synthetic fibers. Natural fibers are heavy in weight. Natural fibers can be damaged by moths and other insects. These fibers are not wrinkle-free. These fibers are not long lasting and hence not durable.
(b) Cellulose is termed as polymer because it is made up of many monomer units.
(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.
(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.
(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.
(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

please help me out, name all 3 parts of the atom.
In the atom, the arrow 1 depicts the proton. The arrow 2 depicts the neutrons, and the arrow 3 depicts the electrons. All three of these are subatomic particles.
What is an atom?An atom is the fundamental structural unit of matter. It consists of protons, neutrons, and electrons. Electrons are negatively charged particles that are present outermost shell of the atom, while protons are positively charged particles that make up the core of the atom. The neutron doesn't have any charge.
Both neutrons and protons make up the core of an atom, while electrons revolve around them. A neutral atom has equal numbers of protons and electrons. Example: the sodium atom.
Hence, the atom showing arrow 1 is a proton, arrow 2 is a neutron, and arrow 3 is an electron.

laws of thermodynamics
Answer:
The Zeroth Law of Thermodynamics states that if two systems are in thermodynamic equilibrium with a third system, the two original systems are in thermal equilibrium with each other. The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances. The 3rd law of thermodynamics will essentially allow us to quantify the absolute amplitude of entropies.
Use an examples to distinguish dominant and recessive phenotypes.
I'm a bit stuck and need some help. Much appreciated!
Think recessive phenotypes as paper and dominant phenotypes as teared paper. Once paper is teared, it can't be fixed. Not even tape. It'll just leave that mess exposed. Same with dominant phenotypes. It just takes one dominant trait to change the looks of future offspring.
If you don't tear the paper, everything is fine. Same with recessive phenotypes. As long as there's no contact with any dominant phenotypes, the looks of future offspring will change.
2. Slime moulds cannot be put neither in kingdom Plantae nor in kingdom Animalia. Give reason.
3. Give the disadvantages of the two kingdom classification.
Answer:
3. In the two-kingdom classification following are drawbacks:-
The plants comprised of photosynthetic and non-photosynthetic species. Fungi, that feed on dead organic matter, were placed under photosynthetic plants. There was another class of classification needed were the organisms with the same characteristics were clubbed into one kingdom. This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. There are some organisms which neither fall into plant nor animal kingdom like Lichens.Explanation:-

explain how bacteria cam develop resistance to an antibiotic?
Explanation:
Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs become resistant.

Fortunately I just took this quiz and received 100%!
The statement that explains scenerio that can bring an increase to winds of the jet stream is A: Faster global convection currents.
Jet streams can be regarded as a fast flowing as well as narrow and meandering, air currents which is found on Earth and other planet. It is a bands of strong wind which moves to east from west in the globe.The wind of jet stream do increase by the action of wind current, because convection current do aid the movement of this this wind from a place to the otherTherefore, option A is correct.
