Answer:
Primates have the greatest brain size to body size ratio of any mammalian group.
Explanation:
Primates can be described as mammals which have digits. Apart from having digits, primates comprise of features like skull and teeth. Primates undergo sexual reproduction to produce offsprings and are characterized of being placental mammals.
Primates are organisms that have the largest size of the brain tin relation to their body ratio. Among primates, Humans have the largest brain to body size ratio, making them by far the most intelligent organism in the animal kingdom.
Answer:
The question is incomplete, it lacks the main questions, those questions are:
a. What is the genotype for black chickens?
b. What is the genotype for white chickens?
c. What is the genotype for erminette chickens?
Explanation:
This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.
Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.
The white phenotype will only be expressed when the genotype is WW
The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.
Answer;
-inhibition of peptidoglycan synthesis
-inhibition of fimbriae synthesis
-interfering with translation at 70s ribosomes
Explanation;
-
Selective toxicity refers to the ability of the drug to targets sites that are relative specific to the microorganism responsible for infection. Sometimes these sites are unique to the microorganism or simply more essential to survival of the microorganism than to the host.
-Antibacterial action generally falls within one of four mechanisms, three of which involve the inhibition or regulation of enzymes involved in cell wall biosynthesis, nucleic acid metabolism and repair, or protein synthesis, respectively. The fourth mechanism involves the disruption of membrane structure.
A Enzymes read the DNA code and build a new DNA molecule from scratch
