Denaturation is done at a very high temperature of 95 degree Celsius for complete separation of mouse DNA.
What is PCR?The polymerase chain reaction, or PCR, is one of the most important uses of molecular biology. To amplify the target DNA molecule, PCR is utilised. In a thermal cycler, PCR is performed.
The three main stages to do PCR are as follows:
1. Denaturation 95 degrees Celsius is a very high temperature at which it is performed. This high temperature causes a process known as denaturation, which causes the DNA strands to split from one another.
2. The temperature is lowered to 55 degrees centigrade for renaturation in order to allow the denaturized DNA strands to anneal with one another.
3. DNA synthesis Deoxyribonucleotides, a thermostable DNA polymerase, and an RNA primer are added to the 3" ends of both strands to carry out the synthesis of new DNA strands relative to the template strands.

write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers
Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

Which best helps scientists determine the age of fossil
Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
The method that best helps scientists determine the age of fossils is radiometric dating. This method is highly accurate and reliable, providing precise numerical ages for fossils.
Radiometric dating is a technique that uses the decay of radioactive isotopes to calculate the absolute age of rocks, minerals, and fossils. Different isotopes have specific half-lives, which is the time it takes for half of the radioactive parent isotopes to decay into stable daughter isotopes.
By measuring the ratio of parent isotopes to daughter isotopes in a fossil or rock sample, scientists can determine how many half-lives have passed and calculate the age of the specimen.
This method is highly accurate and reliable, providing precise numerical ages for fossils and other geological materials, and helping scientists understand the timeline of Earth's history and the evolution of life on our planet.
Therefore, The method that best helps scientists determine the age of fossils is radiometric dating.

Write 5-6 sentences that explains roles of Heredity and probability.
Answer:
Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.

Hello there, kawissaehsshen!!!
The answer here would be A. The organism is a singular thing, so it should be first. The population comes next - it is all the same type of organism living in one ecosystem. Next is community - this is all the living organisms in the area. Lastly, there is the ecosystem - the organisms, their habitats, and everything else.
