Crossed-extensor reflex prevents you from falling when you suddenly lift one foot off the ground in response to pain.
- A withdrawal reflex is the crossed extensor reflex. In the withdrawing limb, the extensors relax while the flexors contract, but in the other limb, the opposite happens.
- This can be seen, for instance, when someone steps on a nail; the affected leg pulls away, while the other leg bears the weight of the entire body.
- Contralateral means that the crossed extensor reflex takes place on the side of the body that is opposite from the stimulus.
- Afferent nerve fiber branches travel from the stimulated side of the body to the opposite side of the spinal cord to cause this response.
- They make connections with interneurons there, which then stimulate or inhibit alpha motor neurons to he muscles of the contralateral limb.

That is false. Physical characteristics of an organism are genetically passed down.
—Evidence—
A characteristic that an organism can pass on to its offspring through its genes.
The set of information that controls a trait; a segment of DNA on a chromosone that codes for a specific trait.
Heredity is the biological process responsible for passing on physical traits from one generation to another.
Carbohydrates are examples of food types or biomolecule utilised by living organisms to acquire energy amon other functions. They are classified into monosaccharides, disaccharides and polysaccharides. Polysacchrides conatin multiple monosaccharides joined together by bonds forming a long chain and a complex molecule, for example, chitin, cellulose and peptidoglycan. These polysaccharides exists as a set of long, parallel strand that are linked to one another, a feature that makes them act a structural molecules withstanding pulling and pushing forces well.

Explatatiom burning something is chemical and melting something is physical.
Answer: The correct answer is- Solar energy, carbon dioxide, and water.
Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.
This phase occurs in the thylakoid membrane of chloroplast.
During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.
This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.
In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.
Thus, solar energy, carbon dioxide, and water is the right answer.
