what is DNA fingerprinting
Answers
Answer: DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA
Explanation:
Answer:
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.
Explanation:
A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if the two DNA profiles do not match, then the evidence cannot have come from the suspect. DNA fingerprinting is also used to establish paternity.

Students investigate how onion cells react to salt (NaCl) solutions of different concentrations. They observe onion cells in three salt solutions under a microscope.
The image of an onion cell in a 3% salt solution is shown.
Onion Cell in 3% Salt Solution
Answers
Answer:
Less than 3%
Explanation:
I'm guessing that since the solution has a concentration of less than 3%, the water would go into the cell to maintain which would make it expand.
Onions cells can react in different ways when place in any solution. The image of an onion cell are said to be:
The first image is greater than 3% The second image is greater than 3%.
When the salt water is added to the onion tissue, cytoplasm pulls away in course of time from the cell wall. So, due to that, water begins to leave the onion cell where it was more highly concentrated to the area where it was less concentrated.
Onion cell does not burst when placed in a hypotonic environment due to the fact that it has strong cell wall, which hinders the burst from taking place.
Onion peel often shrinks in salt solution when water from cells cytoplasm moves out of the cell.

For many generations, a forest has been the home of a single species of bird; these birds primarily eat insects off the forest floor. One year, humans living in the area accidentally introduce a new
species of bird to the forest. This new species has the same diet as the existing species. Which description predicts what will most likely result from these two species of bird living in the same
ecosystem? (5 points)
O Both bird species cannot occupy the same niche and, therefore, one species will die off.
Both bird species would share the forest and have plenty of food and resources.

0
The established species will battle the introduced species of bird until death.
Answers
Answer:
Both bird species cannot occupy the same niche and, therefore, one species will die off.
Explanation:
Introducing a new species of bird will lead to competition among the organism. The food source will not be adequate for both species and competition will set in leading to survival of the fittest.
The population that best compete will most likely to chase away the other species who do not have food because hunger and starvation will lead to death of the other species and the species that is able to find food will survive and reproduce and remain in the niche.

Answers
Answer:
Explanation:
Mutations are effectively errors in the DNA copying or transcription processes. They can occur naturally or be caused by mutagens, either chemical such as benzene or environmental such as ultraviolet light. These mutations concern the basses on DNA and can be as small as one base changing to another or as complex and detrimental as the insertion of a new base along the strand. Such mutations can drastically change the proteins created by an organism and affect entire chromosomes or genes. Some mutations that affect gametes can be passed down from parent to offspring and are called germline mutations. Such mutations can create entirely new alleles and increase a populations genetic variation. One such genetic mutation that occurs in humans in cancer. Cancers are errors in a cells DNA caused by mutations that allow the cell to grow and multiply uncontrollably copying the mutated DNA along the way. One specific type of cancer is breast cancer. Breast cancer has two different types of mutations. There are the BRCA 1 and 2 varieties. According to the charts, the BRCA 1 mutation appears to be more deadly. If a woman carries the BRCA 1 mutation, she has, once again according to the chart, an 18 percent chance of death. All of the women in the table above had a family history of cancer. This would point to the fact that cancer can be passed down as well as contracted from a certain type of mutagen known as a carcinogen. The table also references preventative surgeries in a number of women carrying both the BRCA 1 and 2 mutations as well as some without either. Unfortunately, given the data shown, it is impossible to determine the effectiveness of such procedures. To be able to judge this, data about the survival rates of women who underwent the procedures versus those who did not would be required. The bar graph above the chart also mentions ages. It shows that the numbers of cases of breast cancer increase rather quickly until ages 50-59 and then steadily and slowly decline. Most breast cancer cases occur in women 50-59 years old. This tells us that the mutation takes quite a few years to manifest as it is a genetic mutation and is furthered by the sufferers decreased ability to fight off carcinogens with age. If cancer can be removed by surgeries or by the death of the afflicted, why does it still exist in our population? The answer is simple. Cancer can be passed on hereditarily but that is not the only way for it to be contracted. Carcinogens that exist as chemicals or as environmental factors are present everywhere and can mutate one’s DNA and therefore genes. This can then be passed on to offspring as well.
Genetic variations occur as a result of recombination and mutation. Variations enable organisms to adapt to environmental conditions.
What do you mean by genetic variations?Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination).
The genetic diversity has three different sources: mutation, recombination and immigration of genes. Mutation is the driving force of genetic variation and evolution.
Genetic diversity is important because it gives species a better chance of survival. However, genetic diversity can be lost when populations get smaller and isolated, which decreases a species' ability to adapt and survive.

Create an example in which a mutation entered the gene pool and due to predator pressure. Becomes predominate. For example, think about how the color of the Peppered moths during the industrial revolution changed. The moths were light in color, but due to all the pollution from industry the trees they lived on turned dark making the light moths an easy target for birds. The moths with the mutation for dark color were able to blend with the darker bark and survived. These dark colored moths passed their genes on to their offspring and over a relatively short period of time most of the moths became dark. When the pollution decreased, the lighter colored moths predominated once again.
*Write a paragraph or so it can be a little under. Ill give you brainiest.*
Answers
Answer:
The population of light colour Peppered moths decreases and dark Peppered moths increases.
Explanation:
During the industrial revolution, the population of light colour Peppered moths decreases and dark Peppered moths increases because due to industrial revolution, air pollution increases which spreads a black dust on the trees and as a result the light colour Peppered moths can easily be seen in the dark by its predator and feed on them while dark colour Peppered moths can't be seen in the dark so the predator is unable to feed and as a result the population of dark colour Peppered moths increases.

Scientists studied reproduction in the New Zealand mud snail to answer the question, “Are there benefits to reproducing sexually or asexually?” Which of these hypotheses would least likely aid the scientists as they worked to answer the question?
Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.
Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.
Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.
Answers
Answer:
Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
Explanation:
The main advantage of sexual reproduction is that it increases the genetic variation in the species by creating new combinations of alleles.
However, asexual reproduction produces more offspring, as it is usually a quicker method of reproduction. It also does not require the organisms to socialise to mate.
Sexual reproduction does not reduce the rate of mutation, which is influenced by environmental factors as well as the genome itself.
Answer:
Ur answer is D or Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

For a given trait, the dominant allele of the allelic pair is represented in capital letters (T and G), while the recessive allele is represented in small letters (t and g).
In the case of this plant, whose phenotype is tall and green —both dominant characteristics— and considered pure because both alleles are dominant, the genotype is TTGG.
In the case of a hybrid, the phenotype would be the same but the genotype would be TtGg. A recessive phenotype would be ttgg.You observe a sample under a microscope. It is 5 µm in diameter and has a nucleus. What would it most likely be?

The cell should be eukaryotic cell, as it is 5 micrometer in diameter.
What is eukaryotic cell?A nucleus, mitochondria, and an endoplasmic reticulum are membrane-bound organelles found in eukaryotic cells.
The nucleus of most eukaryotic cells contains the majority of the cell's DNA. The nucleus is the largest organelle in eukaryotes, measuring about 5 micrometers in diameter.
Eukaryotes are thought to have emerged from prokaryotes around 2.7 billion years ago, according to scientists.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells do not.
A nuclear membrane is found in eukaryotic cells. It contains mitochondria, Golgi bodies, and a cell wall.
It also has locomotory organs like cilia and flagella. The nucleus contains DNA, which contains all of the genetic information.
Thus, the cell is eukaryotic cell.
