Answer:
this is rose plant . it's easy . what doubt you have in this question?
Explanation:
the rose is pink in color. it has green leaves with spikes. generally people give red roses on 14 feb because that day was valentine's day.
The reasons are:
- the blood is very low on nutrition
- the leech is not feeding itself regularly
The leech slows it metabolism a lot, so it can survive on very low nutrition. The blood is very low on nutrition, and it is the leech's food source, so the evolution made it preserve energy.
The leach doesn't have the opportunity to feed itself on regular basis, so it takes maximum advantage of any opportunity and consumes as much blood as possible so that it can survive long term when it will not have food at disposal.
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
Answer:
A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.
Explanation:
Missense mutations
CCG codes for Proline amino acid
• Mutation in first nucleotide codes for
UCG specifically encodes Serine
ACG specifically encodes Threonine
GCG specifically encodes Alanine
Missense mutation
• Mutation in second nucleotide specify for coding
CUG specifically encodes Leucine
CAG specifically encodes Glutamine
CGG specifically encodes Arginine
• Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.
