Answer:
the atmospheric changes generated very rapid changes in body size and peak in response to changes in the food supply are led to natural selection, since this type of bird easily adapts to weather conditions and your body assumes these changes for survival
Explanation:
Answer:
Genes that are relatively close to one another on a chromosome will move with one another during the process of fertilization and meiosis. Thus, there will be a lined inheritance for these genes. On the other hand, genes that are found on different chromosomes will have independent inheritances because every pair of the homologous chromosomes will be positioned differently when the
y are arranged at the middle of the cell during the first meiotic division.

Answer:
slow rising check mark curve
Explanation:
Seismographs can be used for this.
Answer:
Answer No 1:
The earliest evidence for the occurrence of viruses was the discovery of an infectious agent in the sap of a tobacco plant. Experiments were set with different filters from which bacteria could pass but viruses being even smaller than bacteria could not pass.
Viruses were difficult to study because they are very small and couldn't be seen even under a microscope.
Answer No 2:
Wendell Stanley made his studies on the tobacco mosaic virus (TMV). Wendell Stanley developed techniques and crystallized this virus. At that time, it was known that even a very simple cell does not undergo crytallization. Hence, Wendell Stanley got to known that this structure is some infectious agent which has the ability of crystallization.
Answer No 3:
The four forms of viral genomes are:
- double-stranded DNA
- single-stranded DNA
- double-stranded RNA
- single-stranded RNA.
Answer No 4:
The capsid can be described as proteins which make up a shell to enclose the genome of a virus. Capsomeres can be described as the protein sub-units from which a capsid is made. The shapes of a capsid can be characterized into
- rod-shaped: helical viruses, or inside spherical viruses
.
- icosohedral: icosohedral viruses or the heads of bacteriophages.
Answer No 5:
The components of a viral envelope involve phospholipids and membrane proteins and proteins and glycoproteins. The phospholipids and membrane proteins are derived from the host cell. The proteins and glycoproteins are of the viral origin.
