Answer:
B. proteinuria
Explanation:
Proteinuria is caused by having high amounts of protein in ones urine. If the kidneys are not working as fine as they should be working, one can have some amount of proteins filtered into their urine. Nephrotic syndrome shows that the kidneys are not working good enough. Glomerulonephritis is as a result of an inflammation of the kidney filters. Too much protein in urine (proteinuria) is an underlying cause of these.
Answer:
A. Only L-amino acids (except for glycine) are used in proteins.
B. The partial double bond character of the α-C-N bond in the peptide group limits the conformations of the peptide group.
C. Hydrogen bonding within elements of secondary structure stabilize certain atomic geometries.
D. Although any one of 20 amino acids is possible at each position, only one is used.
Explanation:
Proteins are biomolecules composed of one or more chains of amino acid residues which are joined together by peptide bonds (this sequence represents the primary structure of the protein). Proteins are made up of 20 types of amino acids which have diverse properties. The secondary structure of a protein refers to the local structure of the protein backbone, which is stabilized by hydrogen bonding between amino groups (—NH2) and carboxyl groups (—COOH) in neighboring areas of the protein. The most common secondary structures in proteins include alpha helices, beta sheets, and random turns. Moreover, the tertiary structure in proteins describes the packing of these secondary structures. The peptide bond (CO–NH) is a stable covalent bond that has a rigid planar structure and acquires partial double-bond properties, thereby peptide bonds undergo very little rotation (i.e., rotation around peptide bonds is restricted). With the exception of glycine, all amino acids are stereoisomers, i.e., there exist mirror images of their structures which are labeled as L (left-handed) and D (right-handed) in order to differentiate between mirror images. All amino acids in proteins have the L-configuration.
Answer:
In a given hybridization between two flowers, red “R” is dominant, and white “r” is recessive.in a cross between two white flowered plants, all of the offspring had white flowers ñ. If a plant grower wanted to produce red flowers, what s/he consider during breeding?
rr X rr = rr, rr, rr, and rr
all white flower (recessive homozygous)
such plant grower should cross a true breed or dominant breed of red flower with a white flower
RR X rr= Rr, Rr, Rr, and Rr
All the above flowers are red (dominant heterozygous)
Explanation:
Answer:
Mutualism: It is a type of symbiotic relationship between two organisms in which both the organisms gets benefits to each other.
For example, in leguminous plants a bacteria is present in the roots of the plants and make symbiotic relationships with each other. In this relationship, plant provides habitat and food to the bacteria and in return the bacteria fixes atmospheric nitrogen for the plant and both get benefit.
Answer:
A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.
Explanation:
The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.
