Answer:

C. It allows scientists to quickly make many copies of DNA.

Explanation:

  • Polymerase chain reaction (PCR) is a technique using which several copies of a DNA template can be made.
  • For DNA fingerprinting the DNA is usually obtained from samples such as hair, saliva, blood, etc.
  • The amount of DNA in samples such as hair or saliva is not enough and thus, amplification of the amount using PCR allows a much reliable DNA fingerprinting to take place.

What is a greenhouse gases and what is Green House effect
TiliK225 [7]
Greenhouse gases(also known as GHGs) are gases in the earth's atmosphere that trap heat, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals.

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.

Color in poison dart frogs is controlled by a single gene with multiple alleles. A blue poison dart frog that is heterozygous fo
8_murik_8 [283]

Answer:

Cb>Cy>Co>Cr

Explanation:

First of al we need to do the Punnett square. As a result we get the genotypes:

CyCb

CyCr

CoCb

CoCr

Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.

Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.

The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.

As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.

Which approach to ecological investigations is illustrated by Biosphere 2? Defend your classification.
valentina_108 [34]

Answer:

The correct answer is : Biosphere 2 is a model based on the creation of a miniature ecosystem with life support systems.

Explanation:

Biosphere 2 is a small model of the biosphere, which is planned by scientists and engineers, that is closed and isolated from the outside world. In this study or research, the strategy for modeling is utilized to show the performance and conduct or behavior of a real biosphere.

Researchers made a model or an artificial situation that can uphold living things. It has a scaled-down model of a tropical forest, a grassland, a sea with a coral reef, a desert, and a mangrove biosphere. In these conditions, a wide range of animal varieties was contained. Furthermore, a group of eight individuals additionally fixed themselves inside it.
