The correct answer is A. Flower color is a recessive trait.

The recessive gene does not show its effect in heterozygous condition according to Mendel’s law of dominance. Thus, in heterozygous condition, dominant gene determines the phenotype for a trait. In this question a plant is homozygous for flower color. This indicates that pink flower determining gene can only be expressed in homozygous condition. Therefore, flower color is a recessive trait.

Which microscope would be used to observe surface structure of corona virus?

Answer:

SEM ANSWER

Explanation:

Electron microscopy is a powerful tool in the field of microbiology. It has played a key role in the rapid diagnosis of viruses in patient samples and has contributed significantly to the clarification of virus structure and function, helping to guide the public health response to emerging viral infections. In the present study, we used scanning electron microscopy (SEM) to study the infectious cycle of SARS-CoV-2 in Vero E6 cells and we controlled some key findings by classical transmission electronic microscopy (TEM). The replication cycle of the virus was followed from 1 to 36 h post-infection. Our results revealed that SARS-CoV-2 infected the cells through membrane fusion. Particles are formed in the peri-nuclear region from a budding of the endoplasmic reticulum-Golgi apparatus complex into morphogenesis matrix vesicae. New SARS-CoV-2 particles were expelled from the cells, through cell lysis or by fusion of virus containing vacuoles with the cell plasma membrane. Overall, this cycle is highly comparable to that of SARS-CoV. By providing a detailed and complete SARS-CoV-2 infectious cycle, SEM proves to be a very rapid and efficient tool compared to classical TEM.

which classification level is broader than the kingdom level; which branch of biology is concerned with the naming and classifyi

shtirl [24]

Domain is broader than the kingdom level.

Levels of classification that are broader than phylum are regions and kingdoms. There are five kingdoms: Monrea, Protista, Fungi, Plants.

Taxanomy is the branch of biology concerned with the naming and classifying of organisms.

Protists are described as diverse organisms because they have many different characteristics. They are either heterotrophs or autotrophs. They are also eukaryotes that are not classified as plants, animals or fungi.

Animals group of organisms includes only multicellular heterotrophs.

If two species belong to the same class, they also belong to the same taxon higher up in the hierarchy. Here they belong to the same side and kingdom.

The gradual change in a species over time is called Evolution.

The levels of classification that are broader than the phylum are domains and kingdoms.

Taxonomy is the science of naming, describing and classifying all living organisms, including plants.
