Answer:
A) Food enters the mouth
B) Esophagus
C) Stomach
D)Cecum
E) Feces is expelled
Explanation:
The food is ingested through the mouth and and then it is transported through the esophagus to the stomach from where it reaches the small and large intestine and then it is finally expelled as undigested or waste foo product.
Based on the above brief explanation, the flow chart depicting food movement are as follows -
a) Food enters the mouth
b) Esophagus - known as the food pipe
c) Stomach
d)Cecum - it is a small pouch connected to small and large intestine.
e) Feces is expelled through rectum
Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.
Answer:
a) the same number of cells in both
Explanation:
In cells reproduction, in both cases we consider the same specie, the same generation time, and we assume the same broth.
The only advantage of the container with more milliliters of nutrients is that when the population increases, it will need more nutrients, so maybe the reproduction rate in the container with 100 ml will be lower.
But if the temperature, the quantity of nutrients are the same in both containers, so the volume is not a variable to affect the speed or low the reproduction rate.
A reduction in volcanic activity and earthquakes. Which results in causing warmer surface temperatures because particles released by volcanoes have a cooling effect.
Answer:
b. The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.
For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
