The biceps brachii muscle is primarily responsible for flexing the forearm at the elbow.

A silent mutation does not change the amino acid sequence of a protein despite a change in the DNA sequence.

Chloroplasts contain chlorophyll, which is essential for photosynthesis in plant cells.

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Chloroplasts are the organelles responsible for photosynthesis in plant cells, converting light energy into chemical energy.

Many organisms, including fungi, starfish, and Hydra, can reproduce both sexually and asexually depending on environmental conditions.

Jellyfish belong to the phylum Cnidaria, which is known for its stinging cells called cnidocytes.

E. coli is a prokaryotic organism, while the others are eukaryotic.

Euglena is classified under the kingdom Protista, which includes diverse unicellular organisms.

Yeast can reproduce both sexually through spores and asexually through budding.

Starfish can reproduce through fragmentation, where a part of the organism can regenerate into a new individual.

Starfish can regenerate lost arms, which is a form of asexual reproduction.

Hydra reproduces asexually by the process of budding, where a new individual develops from an outgrowth of the parent.

Budding is a form of asexual reproduction seen in organisms like Hydra, where a new individual develops from an outgrowth.

Starfish can reproduce by fragmentation, where a part of the organism can grow into a new individual.

Honeybees can reproduce by parthenogenesis, where an egg develops into an organism without fertilization.

Mammals reproduce sexually, while bacteria typically reproduce asexually, and fungi can reproduce both sexually and asexually.

Honeybees can reproduce through parthenogenesis, where unfertilized eggs develop into new individuals.

Mango trees can reproduce through vegetative propagation, which is a form of asexual reproduction.

Al2O3 is an amphoteric oxide, reacting with both acids and bases.

Neodymium (Nd) and Plutonium (Pu) are both f-block elements.

Lanthanum (La) and Cerium (Ce) are both f-block elements, belonging to the lanthanide series.

The mass of an electron is significantly less than that of protons and neutrons.

The electron has the least mass compared to protons and neutrons.

Conduction is a mode of heat transfer and is not associated with wave phenomena.

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

The blue color of the sky is primarily due to Rayleigh scattering, which scatters shorter wavelengths of light more than longer wavelengths.

Pteridophytes, like ferns, exhibit an alternation of generations with both gametophyte and sporophyte stages.

All of the mentioned groups (Angiosperms, Gymnosperms, and Pteridophytes) exhibit alternation of generations in their life cycles.

Substituting (0, -4) into the equation gives 4(0) - 5(-4) + 20 = 0, which is true.
