Answer:
b. chloroplast
Explanation:
Chloroplasts are the double membrane-bound organelles that serve as the site for photosynthesis in eukaryotes. Chloroplasts are the organelles where eukaryotic autotrophs synthesize the organic nutrients by the process of photosynthesis. According to the given information, the first eukaryotic cells were heterotrophs as they derived energy by available organic compounds. They did not synthesize the organic nutrients to use them as fuel. Chloroplasts are not present in heterotrophic organisms such as animals. Therefore, chloroplasts are most likely to have appeared last in the eukaryotic cells.
Answer:
42 kg.m/s if the two are moving in the same direction
Explanation:
momentum formula: p=mv
22kg.m/s+20kg.m/s= p
42kg.m/s=p
the momentum of both objects=42 kg.m/s
Answer:
After the transcription of DNA to mRNA is complete, translation — or the reading of these mRNAs to make proteins — begins. A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
Explanation:
Answer:
1. codominance Both members of an allelic pair contribute to phenotype producing a mixture of phenotypic traits
2 . Rh factor: An inherited protein found on the surface of the red blood cell membrane
3 . hemophilia: A hereditary condition for bleeding due to the inability to clot properly
4 . holandric gene: A gene located on the Y chromosome in XY species
Explanation:
Codominance occur when a pure breeding White flower crosses with a pure breeding Red flower and gives PINK offspring
Rhesus Factor is an antigen that appears on the surface of red blood cells. it is an important factor to consider during blood transfusion.
Hemophilia is a sex-linked condition where the sufferer is unable to have a blood clot.
Holandric gene can ONLY be passed from males (carriers of XY chromosomes) to their sons
