<h2>Answer:</h2><h2>when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell .</h2>

Explanation:

Cell membrane is composed of phospholipid bilayer . Cell membrane is hydrophilic at the surface of outside of the cell and inside surface of the cell thus both surface of cell membrane is a hydrophilic . Interiorly cell membrane is hydrophobic or nonpolar region because membrane composed of long fatty acid chain interiorly . Inner surface of cell membrane have no contact with water or polar molecules . When membrane binds to each other then the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell , while nonpolar parts of cell avoid water and create bilayer phospholipid where hydrophobic tails are in between the hydrophilic heads .

Explain how foods move through the digestive system, describing the actions of the organs, muscles, and digestive secretions alo
LekaFEV [45]

Answer:

Foods are ingested by the mouth where they are chewed by the teeth and savored by the taste buds present in the tongue. In the mouth, saliva breaks down food into substances that are easier to digest. Subsequently, the pharynx allows food to be swallowed and it pushes the food into the esophagus, the contractions of the esophageal muscle allow the movement of the food through the esophagus and to the stomach where the food is mixed with the  juices and are mostly digested. In the stomach nutrients are absorbed. There are particles that are not absorb and they pass to the intestine where other nutrients are transported to the blood, then pass to the large interstinum where there is water absorption and stool formation that are expelled through the rectum.

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter
Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

Anika [276]
Answer is D) <span>Saliva changes the chemical composition of food

A enzyme is a catalyst for chemical reactions, meaning it either facilitates or initiates a chemical reaction. In this case, saliva uses enzymes to change the chemical composition of food into compounds that our body can easily process and turn into energy. </span>
