Please guys answers these questions! If you answer I’ll mark you brainliest. Thank you

1. digestive organs                                     accesory organs

the organs that are directly involved            the organs which helps the  

in digestion like stomach,  small intestine,      digestive organs by thier  

large intestine etc                                             scretions or by other means like

                                                                         liver ,pancreas etc

2.  food                              bolts                            chyme

                                  DIFFERENCES

the substance which    The semi hard       the soup like substance

is eaten by a person.   substance  

it is semi digested in    it leaves oral cavity    it leaves stomach and went to

oral cavity.                   and move to stomach                small intestine        

                                     SIMILARITIES

They all are nutrients containing meterials which are to be digested. they all contain carbohydrates,protiens ,fats and vitamins (somehow if the food is taken from plant source) and they all are about to be absorbed.

3.DIGESTIVE SYSTEM:

            the process in which food substance is broken into pieces and is converted into the simpler substances which can be assimilate by body cells. Different glands scretes digestive juices which digest fats,protiens ,carbohydrates etc e.g gastrin,bile,pancreatic juice and intestinal juice. and at the end all the product remain is excreted out after assimilation.

ORGANS INVOLVED: oral cavity,oesophagous,stomach small intestine ,large intestine.

4.  salivary glands are damaged:

      if salivary glands are destroyed or damaged then no saliva will produce to protect the walls of gut and the gut walls will be damaged by the acidic or basic juices of gut which will causes severe ulcer of oesophagous, stomach or intestinal.

5.CONSTIPATION:

     when too much water is absorbed by the walls of large intestine so the end product which is to be excreted will become so hard that it is dificult to excrete 0it out of body.

  CAUSES: it may be caused by hormonal disturbance ,water deficiency and may be by silliness of a person that he use to be silly to go to the bathroom at time.

6. INGESTION: Taking of food from the outside of the body from different means which contain nutrients essential for body growth.

DIGESTION: Breakdown of food into simpler substance  which can be easily taken by body cells .

ABSORPTION:Large intestine and smaal intestine absorbs the certain amount of nutrients and water from the digested substance to fullfil the body deficiencies. These nutrients are then assimilated into the body.

EXCETION:the substance which remain after absorption is excreted out of the body from exterior opening called anus is called excretion.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
