Carbohydrates: Molecules that provide energy/ fuel and build structures in the body. Example: Sugar. Starch, Cellulose. Building Blocks. Monosaccharides

Lipids:Molecules that store energy and regulate the body's metabolic processes. Building Block: Fatty Acids and Glycerol. Examples: Fats, Steroids, Cholesterol

Proteins: Molecules that provide structural support, cell communication, storage transport, movement, and defense. Building Block: Amino Acids Examples: Enzymes, Structural Components

Nucleic Acids: Molecules that enable living organisms to reproduce genetic information and pass them from one generation to another. Building Blocks: Nucleotides. Examples: DNA and RNA Building Blocks:

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant

mariarad [96]

Answer:

in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:

E. Rr pp *rrPp

Explanation:

According to the information obtained we deduce:

Comb shape is produced by R and P

Comb of walnuts with an R or a P

Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus

Pea comb: 2 recessive at the start and one dominant in the next position

1 single comb: 2 recessive at both loci

Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.

We deduce that for the pink comb the genotype is: Rrpp

and for the pea comb it is rrPp

Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

Which statement most accurately explains how allosteric regulation can change an enzyme's catalytic activity? View Available Hin

Digiron [165]

Answer:

In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.

Explanation:

Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.

Pre-leukemia myelodysplastic features in acute myeloid leukemia may include.

Alona [7]

Answer:

B) Hypogranular neutrophils

Explanation:

Myelodysplastic syndrome occurs due to a disordered production of blood cells in the bone marrow that die before they are even released into the bloodstream. This syndrome is of great clinical significance as they may progress to Acute Myeloid Leukemia. Generally, when this disease has pre-leukemic features it may include hypogranular neutrophils which is one is a feature of neutrophil dysplasia commonly observed in myelodysplastic syndromes.
