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

Answer:

Facilitated diffusion takes place due to a difference in concentration on both sides of the membrane, in the direction of the lowest concentration, and does not require energy.

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.

the process green plant taking food from sun light is called photosynthetis

Answer:

Photosynthesis is a process through which plants and other organisms transform light energy into chemical energy, which is then released to power the organism's metabolic processes through cellular respiration.

Answer:

D. False, it produces ATP

The statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP. Thus, the correct option is D.

Aerobic respiration may be defined as a chemical process in which oxygen is utilized in order to construct energy from carbon dioxide and water. This type of respiration typically takes place in the presence of oxygen to catalyze a given set of reactions.

Aerobic respiration occurs in presence of water. It takes place with help of glucose further convert into pyruvate to derive carbon dioxide, water, and energy in form of ATP. The process of aerobic respiration is also known as oxidative metabolism and cell respiration. In this process, glucose reacts with oxygen to form ATP.

Therefore, the statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP along with carbon dioxide and water. Thus, the correct option is D.

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.

Answer:

in asexual reproduction you do not really get genetic diversity, therefore this is false.

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

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.

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.

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.

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.

D. Lemurs isolated to the island of Madagascar

Explanation:

Endemic is to be native and restricted to a certain place.

Endemic species are organisms that are limited and confined to a particular region. Lemurs show endemism as they are isolated to the island of Madagascar. Thus, option D is correct.

Endemism is a biological term used to depict the distribution of the organism in an area that becomes its habitat. It is shown by species that are limited and bounded to one geographical location.

Endemism is shown by the species due to genetic isolation that separates the population or the species in a geographical area and does not allow the genetic material to exchange by reproduction.

Koalas and Kangaroos in Australia, Lemurs in Madagascar, lion-tail macaque and Nilgiri blue Robin in India, and camellia plant in Japan are some endemic species.

Therefore, option D. the Lemurs in Madagascar are an example of endemic species.
