Answer:
RNA is single-stranded and composed of nitrogenous bases, a phosphate group, and pentose sugar.
Explanation:
RNA is different from DNA because instead of having two matching bases; it is only made of one strand of nitrogenous bases. These bases are attached to the phosphate, which holds the whole strand of RNA together. The sugar acts as a carrier for the bases. The sugar in RNA is known as ribose and contains 5 carbon molecules. This is why it is called pentose sugar.

The consensus is that the coelacanths and lungfishes (Sarcopterygii) represent an evolutionary link between ray-finned fishes and tetrapods. What is the major feature in the Sarcopterygii that supports this hypothesis?
Answer:
Choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares.
Explanation:
Sarcopterygii also known as lobe-finned fishes which usually possess a choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares are present internally. The lungfishes are considered the closest living relatives of tetrapods because of the presence of some common features. The African lungfish has epithelial crypts located at the base of the lamellae of the olfactory epithelium that express markers of the vomeronasal receptors in tetrapods.

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:-

As compared to the circulatory system of most fishes, the circulatory system of adult amphibians has the advantage of a single circuit. partially-separate circuits for gas exchange and systemic delivery of blood. complete separation between oxygenated and deoxygenated blood. a four-chambered heart. a pocket of the gut that serves as an air bladder.
Answer:
Partially separate circuits for gas exchange and systemic delivery of blood.
Explanation:
Adult amphibians have separate circuits for gas exchange and systemic delivery of blood. Fishes usually breathe through gills and very few have nostrils. The fishes can breathe underwater with the help of their gills.

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.

Answer:
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself
Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.

A population of birds can have large, heavy beaks or thin, long beaks.
What can we say based on this data?
Select one:
We cannot conclude anything without having more data.
Having heavier beaks is a survival advantage.
Having longer beaks is a slight survival advantage, but having more data would help to confirm.
undo
There is no survival advantage between having heavier beaks and longer beaks.
Answer:
We cannot conclude anything without having more data.
Explanation:
All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data
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.

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
