The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.
1. Cellular respiration is a metabolic pathway that occurs inside the cell. During cellular respiration, glucose molecule is broken down in the presence of oxygen.
2. During cellular respiration, ATP (Adenosine Triphosphate) molecule is also produced that acts as energy currency and directly powers cell work.
3. Amylase is an enzyme that helps in digestion. It catalyzes the hydrolysis of starch into simple sugars. If amylase is present in normal amount it will break down starch into disaccharides. If the amount of disaccharidase amount is less than usual then less disaccharides will be broken down into monosaccharides. Thus the production of monosaccharides will decrease.
4. In the reactions shown above, the end product is largely dependent on the last enzyme. If Enzyme3 is in less amount than usual then there will be greatest reduction in the production of G and H. This is because the formation of product in any reaction is dependent on the substrate concentration and enzyme concentration.
Euglena is green in color because of the chlorophyll that is contained in the chloroplast of that organism and the body structure that is located at its base is known as flagellum
.
Explanation:
Euglena are species that are found in the fresh and salt water. They are abundantly found in inland waters where they manage themselves to bloom in large amount and color the water surface of ditches and ponds green.
This green color which them form are mainly due to the chlorophyll that is contained in the chloroplast of the organism. chlorophyll is known to be the pigment that is responsible for the green color.It is the cause for the green color in this case too.
Euglena contains a specialized body structure which is located at the base of the tail by which it manages to move.
This specialized structure is known as Flagellum.
Answer:
C) occurs by simple diffusion because lipids are able to penetrate the hydrophobic fatty acid tails within the plasma membrane
Explanation:
After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can. Free fatty acids and monogycerids can just diffuse across the plasma membrane because of their nonpolar nature.
Some absorption (e.g. for cholesterol) may be facilitated by specific transport proteins.
Answer:
A. Salamanders
Explanation:
Specialists species are species that can thrive in a unique and limited range of resources. They require a specific environmental condition to reproduce and survive in environment and also have limited or few diets they need for nutrition. These limiting characteristics put them at a disadvantage of being endangered and threatened.
Salamanders are endangered species that are fast going into extinction. They require wetland (freshwater pools) for reproduction to be possible, and feed mainly on insects. This makes them specialist species.
Ospreys, snapping turtles, and beavers are all generalist species. They can all thrive in a wide range of environmental conditions, and also have varieties of diets they can get nutrition from to survive.
