Answer:
dna can be used because no dna is the same unless there are identical twins. with using dna to solve a crime, you can test the dna to see if there are any similariteis or if they are exact. If there are similarities that means that someone related to that person is the person in charge of the crime. This is why dna evidence is one of the most important parts when looking at a crime scene because it is the most exact and precise way of convicting someone
Explanation:
Answer:
Each person’s DNA is unique.
Scientists use variable regions in DNA to create a DNA profile.
DNA samples can be taken from blood, bone, hair, or other body tissues and
products.
DNA from a crime scene can be compared to DNA from a suspect.
DNA typing can be used to solve old cases.

Some salmon have been genetically modified to grow bigger and faster than wild salmon. They are grown in fish-farming facilities. These genetically modified fish should not be introduced into a natural habitat because
A)
the salmon would recycle nutrients at a rapid rate
B)
their rapid growth rate could cause them to outcompete native salmon
C)
they would not have enough oxygen for survival
D)
they would reproduce asexually once they were released
Answer:
B
Explanation:
Their growth rate would cause them to grow much larger than the native salmon meaning they require more habitat space and sustenance to live. This would drive out the native salmon as they wrestle for food and space.

How do convection currents work?
Answer:
Convection currents form because a heated fluid expands, becoming less dense. ... As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid.
Explanation:
Convention currents work by forming a heated fluid expanding making it less dense. As the current rises, it pulls cooler fluid down to replace it.
If a muscle contracts isometrically for a long period of time, an EMG (which records the electrical activity in the muscle) recording shows that as the amplitude (frequency of action potential) increases, the contractile force slowly decreases. What is the explanation for this?
Answer:
During the course of a continuous isometric contraction of given strength, the electrical activity progressively increases. This is due to recruitment of motor units taking place to compensate the decrease in force of contraction occurring in the fatigued muscle fibres.

According to the cell theory, which of the following best describes the role of cells in living organisms?
A:Cells are the basic building blocks of all living organisms.
B:Cells make up the tissues that are present in all forms of life.
C:Cells are produced spontaneously when living organisms need them.
D:Cells contain the same specialized organelles required for life in both prokaryotic and eukaryotic organisms.
Answer:
D
Explanation:
photosynthesis is an example of...
an exothermic reaction
an endothermic reaction
a reaction that gives off heat
a reaction that emits energy
Answer:
Endothermic reaction
Explanation:
Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.

The cell cycle of yeast cells grown in the nutrient-poor environment is approximately what percent of the cell cycle of yeast cells grown in the nutrient-rich environment.
Answer: 168
Explanation:
The cell cycle of yeast cells grown in the nutrient-poor environment is approximately 168 % of the cell cycle of yeast cells grown in the nutrient-rich environment. Hence option 1 is correct.
What is cell cycle?Cell cycle is defined as the cascade of cellular activities that lead to cell division into two daughter cells. The primary purpose of the cell cycle is to accurately divide the enormous amount of DNA found in the chromosomes into two daughter cells that are genetically identical. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide.
The interphase and M-phase are the two phases that make up the cell cycle. About 90% of the cycle is made up of interphase, during which the cell develops and copies its chromosomes in order to divide. Undifferentiated ESCs have a G1 and S cell cycle percentage of 15-20% and 60–70%, respectively, however as the ESCs differentiate, this ratio changes.
Thus, the cell cycle of yeast cells grown in the nutrient-poor environment is approximately 168 % of the cell cycle of yeast cells grown in the nutrient-rich environment. Hence option 1 is correct.

In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilities that the offspring can fold the tongue?
Explanation:
The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case: 1. dominant parent and recessive parent 2. heterozygous parents Answer: 1. dominant parent and recessive parent: dominant parents can be represented by LL and recessive parent is represented by II, so the gametes would be L, L and I, I. so, LL LI LI LI so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I|so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I| In this case, one is pure dominant and two heterozygous whereas only one is recessive the phenotype of offspring that cant fol the so, tongue would be: 75% = 3/4

Explanation:
Hurricanes tend to disperse after making landfall because the land is much hotter than the ocean water.
Answer: False
Explanation:
For a Hurricane to keep going it needs to have hot air constantly going up and cold air coming down. When it gets to land, it loses access to the heat and moisture of the sea which is greater than on land. This forces it to weaken and to eventually dissipate.
Therefore, hurricanes disperse after making landfall because land is not as hot as the ocean water.
