What Is Half-life Of Mercury-203

Answers

Answer 1

Answer:

The correct answer is - 47 days approximately.

Explanation:

In this given graph is the decay graph of mercury-203, there is a representation of the relation of change in the amount of the mercury -203 with the time in days. The red arch is showing the change of parent isotope percent with elapsed time and the green dashed arch showing the daughter isotope percentage with isotope.

The half-life is the required time to decay an element to half of its inital amount, according to the definition the half-life of parent isotope mercury-203 is the amount where the red arch is present at 50% in the graph that is 47 days approximately.

Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards?


A. High daytime temperatures allow them to grow as large as the food supply will allow.


B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.


C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.


D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.

Answers

Answer:

A. High daytime temperatures allow them to grow as large as the food supply will allow.

Explanation:

Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.

Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.

Answers

Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

Describe the bonding between ionic compounds

Answers

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Meteorologists often try to predict what the high temperature of a day will be several days beforehand. Why do meteorologists not try to predict the high temperature of a day six months in the future?

A. Weather does not follow any predictable patterns.

B. Meteorologists have this information but choose not to share it with the public.

C. It is impossible to know what season it will be six months in the future.

D. Weather is a highly complicated system that is very difficult to predict.

How does waste removal in a fetus differ from waste removal after birth?


A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.


B) Fetal waste is removed through the rectum; infant waste is removed through the chorion.


C) Fetal waste is removed through the ductus venosus; infant waste is removed through the rectum.


D) Fetal waste is removed through the large intestine; infant waste is removed through the ductus venosus.

Answers

Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.

Explanation:

A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.

Why are only four amino acids produced by 5 codons? I need this answer ASAP

Answers

Answer:

My answer (that the information we have about codon structure is limited to the observations we can make now) is similar to the first part of your answer: that the number of amino acids that can be encoded is a function of codon length, in that both imply the (circular) argument that we must need more than 14 amino acids (plus a start and a stop, making 16) because we observe three nucleotide codons rather than two nucleotide codons. It would be nice to have a noncircular argumentf for why the minimum number of distinct amino acids is more than 14, but that is beyond my ability to construct

A, T, C, and G are the only letters found in DNA, however, a protein may include up to 20 distinct amino acids. Codons assist in translating the DNA code into a protein code at this point.

What are genetic codons?

For the body to develop and work effectively, 20 different amino acids are required. All 20 of them are crucial for your health, but only 9 are considered to be absolutely necessary.

This is due to the degeneracy of genetic codes, one of their characteristics, the remaining 3 codons are called "stop" codons since they do not code for any amino acids. The sequences UAA, UAG, and UGA include the stop codon information.

Therefore, only 61 of the 64 possible codon combinations code for amino acids.

A. The birth rate was equal to the death rate.

B. The death rate was greater than the birth rate.

C.The rate of emigration was equal to the birth rate.

D. The rate of immigration was greater than the death rate.

Answers

Answer:

A. The birth rate was equal to the death rate.

Explanation:

The point X is the carrying capacity and this pajae could be ascribed as the plateau stage of population growth, whereby the maximum number of individuals of a particular species which the environment can support has been reached. Hence, giving a long, flat area of the logistic growth curve. At the stage marked x, growth would seize as the population hovers to attain equilibrium with the natality and fatality rate becoming equal, that is birth rate will be equal to the death rate in the population.
