Answer:
The correct genotypic notation for a wild type with phenotypic characteristics: red eyes, long bristle and round eyes will be any of CNRDll, CnRdl, CnRDl or CNRdl if c, n, r and d are capable of independent assortment and CNRDl if they cannot.
Explanation:
The eye color and bristle size is coordinated by either recessive cn and dominant CN or Cn genes. The wild type in questions has red color eyes, which is a dominant trait coordinated by CN or Cn if c and n can undergo assortment independently or just CN if they cannot. The second characteristics of the wild type is long bristle. We were told that reduced bristle is coordinated by recessive rd Gene. Then the long bristle in our specimen wild type will have dominant genotypic notification of RD or Rd, depending if r and d can undergo assortment independently. The last trait is a round eyes, which is a recessive trait controlled by recessive allele l. Therefore, the combined characteristics of red eye color, long bristle and round eyes shape of the wild type will be CNRDl or any of CNRDll, CnRdl, CnRDl CNRdl depending on the segregation pattern of c, n, r and d.
Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
The four main classes of organic compounds (carbohydrates,
lipids, proteins, and nucleic acids) that are essential to the proper
functioning of all living things are known as polymers or
macromolecules. All of these compounds are built primarily of carbon,
hydrogen, and oxygen but in different ratios. This gives each
compound different properties.
Carbohydrates are used by the body for energy and structural
support in cell walls of plants and exoskeletons of insects and
crustaceans. They are made of smaller subunits called
nionosaccharides. Monosaccharides have carbon, hydrogen, and oxygen
in a 1:2:1 ratio. Monosaccharides or simple sugars include glucose,
galactose, and fructose. Although their chemical formulas are the
same, they have different structural formulas. These simple sugars
combine to make disaccharides (double sugars like sucrose) and
polysaccharides (long chains like cellulose, chitin, and glycogen). Color
code the glucose molecule on this worksheet (carbon-black, hydrogenyellow,
and oxygen-red). Use your textbook to help draw the
structural formulas for fructose and galactose:
The answer is D.
Homo naledi seems most likely to be a member of the genus Homo; however, its small brain size is regarded as a primitive hominin trait more reminiscent of australopithecus.
Homo naledi is an extinct species of hominin, which anthropologists first described in September 2015 and have assigned to the genus Homo.
