This process occurs in the (chloroplast / cell wall / mitochondria) which contains the green pigment (carotene / chlorophyll / xylophene). Plant cells are surrounded by a plasma membrane and a (cell wall / chitin / slime layer). The cell wall is composed of proteins and (starch / cellulose / chitin) which is a polysaccharide that we can not digest but we can write on it. The (skeleton /

All of the following are parts of the honeybee's processing of honey EXCEPT:     producing a small amount of gluconic acid.     concentrating the sugars to a supersaturated state.     conversion of some glucose and fructose into sucrose.     conversion of most of the fructose to the β-D-fructopyranose form.

1 2 3 4 description Cell membranes in both plants and animals are primarily made of this kind of molecule. This kind of molecule is usually a short-lived messenger molecule that conveys information about pain and inflammation. When circulating nutrients are insufficient to meet the body's energy needs, this type of molecule is broken down into smaller molecules that can be oxidized in cells to supply energy. This molecule is the starting point for the synthesis of many hormones, including the sex hormones testosterone and estradiol. Which molecules fit this description? 0 0 U 0 none of them 0 none of them Onone of them none of them

Which of the following is incorrect about the collagen structure? a. The covalent cross-links between the individual chains stabilize the collagen structure b. None; all the other choices are correct The helical structure is cross-linked (with covalent bonds) at both ends Od. Gly residues are all located in the center of the helix (i.e. between the individual chains) C.

The connection between these words

Now, let’s start by tapping into some important ideas and words. Below is a tic-tac-toe board. Make a straight line (horizontal, vertical or diagonal) by clicking on three words that you can connect in a complete sentence or thought. Write your sentence in the space beside the board. Create three sentences in total.

In conditions of dehydration, plant cells can increase their water retention by regulating the function of some or all of their aquaporins, membrane-bound protein channels that allow water to move through the cell membrane via facilitated diffusion. Which of the following describes a likely mechanism by which aquaporins can be used to regulate the movement of water across the plant cell membrane? A B с D Synthesis of additional aquaporins by the plant cell ribosomes will allow the cell to coun- teract the movement of water out of the cell. Inhibition of ATP hydrolysis will make the aquaporins unable to remove water from the cell and cause more water to remain in the cell. Inactivation of aquaporins will make water molecules unable to move across the plant cell membrane and allow more water to remain in the cell. Inhibition of the plant cell Golgi apparatus will decrease the production rate of vesicles and slow down the exocytosis of water molecules.
