Details about comets are described below.
Explanation:
- A comet is a very small solar system body made mostly of ices mixed with smaller amounts of dust and rock. Most comets are no larger than a few kilometres across. The main body of the comet is called the nucleus, and it can contain water, methane, nitrogen and other ices.
- Sometimes comets are referred to as “dirty snowballs” or “cosmic snowballs”. Comets orbit the Sun in elliptical paths – just like the planets.A comet has four components: a nucleus, a coma, a dust tail and an ion tail.
The nucleus of a comet contains the vast majority of its total mass.
- Comets are icy bodies in space that release gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.
- Comets are made of water, ice, dust, and gasses likes carbon monoxide and methane. After identifying what is in the nucleus, you will know what the coma and tail are made of.
Answer:
Linkage may be defined as the transmission of chromosome to the next generation that are located on same chromosome. Linkage results in the formation of recombination progeny.
PDS (parental ditypes) and non parental diypes can be used to find linkage in the Neurospora and other organism Parental ditypes has the genotype same as parental genotype whereas non parental ditypes contains recombinant progeny. If the ratio and arrangement of PDS and NPDs is 2:4:2 or 2:2:2:2. This means linkage is present between the gene and centromere of an organism.
Answer:
Hiya there!
Explanation:
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.
