Answer:
It starts in the mouth Enzymes break down food
Explanation:
Mechanical digestion is a type of digestion which is done by breaking of food materials into small pieces through physical means such as cutting and crushing by teeth and muscular contraction of stomach while the break down of food molecules by the action of enzyme such as saliva etc is chemical digestion. Chemical digestion helps in speeding up the process of digestion.
Answer:
D. Enzymes break down food.
Explanation:
Mechanical digestion is the physical breaking down of food that starts in the mouth by chewing. Enzymes would be part of the chemical digestion.
Answer:
Toucans, frogs, snakes, and lizards are biotic influences in tropical rainforests.
Answer: The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2.
The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2+ 6H2O + Energy.
Explanation: Photosynthesis and cellular respiration are two opposite reactions. In photosynthesis, plants use carbon dioxide, water and sunlight to produce glucose and oxygen while in cellular respiration, both plants and animals breakdown glucose in the presence of oxygen to produce carbon dioxide and water with the release of energy.
Photosynthesis occurs only in plants and some photosynthetic bacteria while cellular respiration occurs in both plants and animals. The energy released from the breakdown of glucose in cellular respiration is used to drive other cellular processes.
Each of the two processes depends on the other for the supply of its reactants. Photosynthesis depends on cellular respiration for the supply of carbon dioxide and water while cellular respiration depends on photosynthesis for the supply of glucose and oxygen.
The balanced chemical equation for photosynthesis is 6CO2 + 6H2O -> C6H12O6 + 6O2. The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 -> 6CO2 + 6H2O. These equations represent the conversions that occur in photosynthesis and cellular respiration.
The balanced chemical equation for photosynthesis is. The equations represent the conversion of carbon dioxide and water to glucose and oxygen in photosynthesis, and the reverse conversion of glucose and oxygen to carbon dioxide and water in cellular respiration.
6CO2 + 6H2O → C6H12O6 + 6O2
The balanced chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O
The equations represent the conversion of carbon dioxide and water to glucose and oxygen in photosynthesis, and the reverse conversion of glucose and oxygen to carbon dioxide and water in cellular respiration.

Answer:
Chromatids of homologous chromosomes exchange corresponding segments.
Explanation:
The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I, but not in meiosis the II. After pairing up of in the prophase I, homologous chromosomes are able to exchange some corresponding segments and a cross-over occurs. Thanks to the cross-over event, each chromosome will have a new combination of genes. Without this, parents will produce gametes with only two different gene combinations.
Answer:
Chromatids of homologous chromosomes exchange corresponding segments.
Evapotranspiration is the conversion of liquid water to vapor by energy from the sun and plant life processes.
