This dichotomous key helps scientists classify within the arthropoda phylum. If scientists discover an organism with: less than 10 legs, 6 legs, wings, wings with 1 or 2 colors, with legs that are approximately the same length, wings that are not net-like, and wings that meet in a straight line down the back, how would this organism be classified?

Your friend makes a claim that the image to the right shows facilitated
diffusion. You are an educated Honors Biology student, and you believe
that he/she is incorrect in their claim. Make a claim as to which type of
cellular transport is represented in the image (1 point)State TWO pieces of
evidence from the image that supports your claim (2 points).*

Answers

Answer:

Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.

Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

Diffusion is the movement _____.

of molecules to an area of lower concentration

of molecules through the cytoplasm of a cell

of water through a selectively permeable membrane

of molecules to an area of higher concentration

Answers

Answer:

what measures to be taken in an operating room

Answers

You have to make sure all of your equipment is clean

Answer:

infection control- clean equipment to prevent spread of germs

All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation

Everything needs to be sterile

All instruments need to be inspected for any signs of contamination after the sterilisation process

Shoes from outside should never be worn inside an operating room

Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment

The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids
