Answer: plants and animal cannot use nitrogen in the arthmosphere because nitrogen is a noble gas, unreactive and it is not available in the form they can use them.

Explanation:

Nitrogen is the most abundant gas in the atmosphere constituting about 80% of total gases available.

Nitrogen is important for plants and animal to build proteins, aminoacid and DNA. Nitrogen in the arthmosphers cannot be use by plants and animals because it is unreactive and not available in the form that it can be use.when organisms die, their bodies decompose and nitrogen is released to the soil, bacteria convert the nitrogen to nitrate in a form that can be absorbed by plants roots and used. The leguminous plants have root nodules that contain nitrogen, nitrogen fixing bacteria in the soil convert nitrogen to nitrate to be use by plants. This is a summary of the entire nitrogen cycle.

Answer: Atmospheric Nitrogen is unreactive

Explanation:

The atmosphere is made up of about 80% Nitrogen, 16% oxygen, about 4% carbon dioxide, rare gases etc.

However, the 80% Nitrogen is highly unreactive, and needs to be trapped by competent micro organisms known as nitrogen-fixing bacteria in the root nodules of legumes.

Then, it is converted to several forms like nitrites, nitrates (easily absorbed by plants), ammonia and finally escape to the atmosphere again.

This brief illustration explains the NITROGEN CYCLE, and it is the only means by which plants and animals can use the highly unreactive nitrogen

The varicella virus is a common childhood virus that causes chicken pox. Shingles, a disease also
Ratling [72]

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

  • Lytic cycle
  • Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.

Which of the following shows all of the tripeptides that can be formed from one molecule each of lysine (Lys), threonine (Thr),
Ierofanga [76]

Answer:

LysThrHis, LysHisThr, HisLysThr, HisThrLys, ThrLysHis, ThrHisLys

Explanation:

You easily combine the options for the tripeptide if you made a chart

Also you can calculate the posibilities with the factorial function in the calculatio (x!): 3*2*1 (you can multiplicate the number of amoniacids by the followed numbers until 1) = 6

explain why it is important to keep the levels of nucleotides relatively balanced in the context of dna and rna synthesis
juin [17]

Answer:

Read Below

Explanation:

Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected
