In your own words, describe what information the visible DNA fingerprint provides for each DNA sample

Biology

Answer:

The visible DNA fingerprint can help extract DNA which, after analysis, can accurately identify the suspect or perpetrator of the crime.

Explanation:

DNA Fingerprinting:

  • DNA fingerprinting is a molecular analysis tool that can help identify a suspect in a crime through DNA extracted from fingerprints.
  • Specific patterns in the DNA, known as polymorphisms, can be identified through DNA fingerprinting.
  • The DNA fingerprinting process involves:
  1. Extraction and purification of the DNA from the fingerprint.
  2. PCR amplification to obtain high yield.
  3. Fragmentation of the DNA by use of restriction enzymes.
  4. Gel electrophoresis analysis of the fragmented DNA.
  5. Analysis of gel to compare the size of the bands.

If red foxes were to go extinct, what would be the two most likely effects on the ecosystem
wel
Red foxes are omnivores. Their diet includes small animals such as  birds, squirrels, rabbits and mice, but also berries, grasses and insects such as crickets, caterpillars, grasshoppers and beetles. Red foxes are therefore primary as well as secondary consumers, and even apex predators. Their removal from an ecosystem would most likely reduce the predation pressure on small animals and insects, and may result in population explosions of these prey animals. This in turn may result in additional pressure on the ecosystem as these animals exceed the carrying capacity, and could lead to other plant and animal species within the food web being decimated. Basically, the balance of the ecosystem would be lost until a new equilibrium can be established.

Can someone pls help me<br>​

Answer:

16. mitochondria

17. lysosomes

18. smooth Endoplasmic Reticulum

19. golgi body

20. golgi complex

Explanation:

16. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell

17.  While cells mainly use lysosomes to dispose of trash. Sometimes they simply hang onto their trash, performing the cellular equivalent of sweeping it under the rug

18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.

19.  The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.

20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.

Analyze the result of a cross between two organisms that are both heterozygous for two different genes (AaBb) use a Punnett squa
krok68 [10]
(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.

(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.

(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
