The following structural changes occur as conducting tubes become smaller;

- support structures change. The trachea has more hyaline cartilage than the bronchioles

- epithelium type changes with bronchioles having ciliated columnar cells with the trachea having tall       columnar pseudostratified

eimsori [14]
Janelle should talk to any trusted adult for advice. I'm assuming she can't just get her local physician any time she wants to talk to them. Someone else who drinks is not reliable. The people at the party will probably drink too.

Which of the following statements is/are consistent with the fluid-mosaic model of membranes? (Select all that apply.) The lipid
vfiekz [6]

The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and  Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane

According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.  

The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.

Components of the cell membrane include:

• Phospholipids – Form a bilayer  

• Cholesterol –improves stability and reduce fluidity

• Proteins –integral (transmembrane) or peripheral  

• Sugars-usually attached to proteins.

Drag the numbers to put the following steps in the correct order.
deff fn [24]

Answer:

- In glycolysis, glucose is split into two pyruvate and makes some ATP

- The Krebs cycle produces ATP, NADH and CO2

- NADH gives electrons to the ETC

- As electrons move down the ETC, a H+ gradient is made

- H+ pass through the ATP synthase to make ATP

Explanation:

This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).

- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.

- Kreb's cycle produces ATP, NADH and CO2.

- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).

- Electrons move down the ETC to produce a proton (H+) gradient

- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.
