A new disease has recently been discovered in a community, and you have been brought in to investigate. The disease appears to p

inessss [21]

From the options what can be said about this disease is that ( B ) : The Pathogen replicates without using host cells' replication machinery and it is directly transmitted.

Since The new disease transmits from one person to another via handshake that means that the disease is a directly transmitted disease, also given that the disease can be cured with the use of antibiotics shows that the causative agent is not a virus but a bacteria. bacteria are living organisms with their own machinery for self replication, therefore they do not need the host cell to replicate the disease before transmission.

Hence we can conclude that the disease is caused by a Pathogen which replicates without using host cells' replication machinery and it is directly transmitted.

The species that is known as a robin in England has a yellow breast, and another species that is known as a robin in the United

Fittoniya [83]

Answer:

The correct option is <em>C. Different species can share the same common name.</em>

Explanation:

A single organism might have the many common names or it might happen that different species have the same common name in different parts of the world. Common names can be sued when people from the same country, speaking the same language are talking.

But as scientific research is carried out in all parts of the world, scientists made up the system of binomial nomenclature. Under this system, each specie is given a unique name .

HELP!! RELATIVELY QUICKLY PLEASE!!

Daniel [21]

Okay, first the clear up. The Homozygous dominate trait is RR and is Red, the Heterozygous trait is Rr and is Pink, and the Homozygous recessive trait is rr and is white.

Part A: The co-dominance or incomplete dominance mixes the colours together, so the phenotype for the Heterozygous Rr flower is pink.

Part B: This question is easiest to explain with a punnet square... so. Diagram attached.

Part C: To get only Heterozygous genotypes, the gardener must cross only White flowers with red flowers. Because both these flowers are homozygous pairs, it means that any offspring created from that group would have a mix of the two. This is clearly seen in the F1 generation of Mendel's experiments for further proof. If any other pair is chosen ie Red with red: all red offspring, white and white, all white offspring. Pink and pink, a 1:2:! ratio. Red and Pink: 1:1 ratio of red and pink. White and pink: 1:1 ratio of pink and white. Red and white: Only pink offspring.

Hope that helps, message if you need it explained.
