Blocking would be best used 'by blocking on chicken type'. This means conducting separate trials for different types of chickens while testing the chicken feed because the type of chicken was determined to impact egg production.
In a scientific experiment where the aim is to conclude whether a certain chicken feed leads to higher egg production, blocking would be used to control the variables that might affect the result of the experiment. According to the information given, chicken's water intake is said to have negligible influence on egg production, however, the type of chicken does impact the production quantities.
Therefore, the ideal way to apply blocking to the experiment would be by differentiating the groups of chickens based on their type; this method is referred to as blocking on chicken type. The implication of this is, testing different chicken feeds on different types of chickens separately to ensure the accuracy of the experiment results by eliminating confounding factors.

Answer:
The correct answer would be the virus envelope.
Viral envelope is a protective covering present around the capsid proteins in some viruses.
It is usually derived from the cell membrane of the host and thus it is composed of lipid and viral proteins.
It provides stability to the viral particle, helps in protecting the viral genome, and aids in the fusion of the virus with the membrane of the host.
Examples of viruses in which envelope is present: herpesviruses, poxviruses, flavivirus, hepatitis D et cetera.
Examples of viruses in which envelope is absent: adenoviridae , papillomaviridae , picornaviridae , caliciviridae et cetera.
b. seed.
c. cone.
d. flower.
The answer is B- Seed.
Explanation:
RNA polymerase II is inhibited by certain drugs and toxins. One well-known inhibitor of RNA polymerase II is a toxin called α-amanitin, which is found in some species of poisonous mushrooms, such as the death cap mushroom (Amanita phalloides).
α-Amanitin functions by binding to RNA polymerase II and preventing it from transcribing messenger RNA (mRNA). This inhibition of mRNA synthesis disrupts the process of protein production in eukaryotic cells, which can ultimately lead to cell death and various toxic effects in the affected organism.
It's important to note that inhibition of RNA polymerase II is highly toxic and can be fatal if ingested. Poisoning from mushrooms containing α-amanitin can result in severe liver and kidney damage. If there is a suspicion of mushroom poisoning, immediate medical attention is crucial.
Answer:
the convective zone of the sun
Explanation:
In the the convective zone of the sun the energy is carried upwards by the rising hot gas and subsequently it cools and descends, that is to say that the energy is transported mainly by means of convection.
In this area, circular current patterns are formed where the hot plasma rises and the cold plasma descends.
