DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in parentage testing, to establish immigration eligibility, and in genealogical and medical research. DNA profiling has also been used in the study of animal and plant populations in the fields of zoology, botany, and agriculture.

Which of the following is true about molecules?
1. Composed of the two same atoms
2. Composed of two different atoms
3. H2O is an example of molecule
4. All of the above is true.
Answer:
4) All of the above is true.
Why?
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. This is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom. This is written as H2O.

10+6h=34 what does h equal?
Answer: h = 2.125
Explanation:
Simplifying
10h + 6h = 34
Combine like terms: 10h + 6h = 16h
16h = 34
Solving
16h = 34
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '16'.
h = 2.125
Simplifying
h = 2.125Answer:
The answer is h = 4.
Explanation:
1) Subtract 10 from both sides.
[tex]6h = 34 - 10[/tex]
2) Simplify 34 - 10 to 24.
[tex]6h = 24[/tex]
3) Divide both sides by 6.
[tex]h = \frac{24}{6} [/tex]
4) Simplify 24/6 to 4.
[tex]h = 4[/tex]
therefor, the answer is h = 4.
what is a rain shadow area
Answer:
Rainshadow is the area where rain is not experienced
Answer:
Explanation:
A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. ... On the other side of the mountain—the rain shadow side—all that precipitation is blocked. In a rain shadow, it's warm and dry.

WILL MARK BRAINLIEST Identify 2 organisms that would have a decreased food supply if insects were removed from the food web,
Answer:
Frogs and voles would have less food supply.
Explanation:
There would be more food for the rabbits and slugs, so their populations would increase. However, ( there would be less food for the frogs and voles), so their populations would decrease. This means less food for the foxes and hawks. However, there are likely to be more rabbits and thrushes for them to eat, so their populations might stay the same.

How does the support structure of echinoderms differ from that of arthropods?

Answer:
I would say the main difference is their covering. Arthropods have an exoskeleton, which protect their soft bodies while echinoderms have living endoskeletons. Overall, arthropods are more closely related to nematodes than echinoderms.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
a Phenylalanine, serine, leucine
b Serine, alanine, leucine
C Methionine, serine, leucine
d None of the above
Answer:
A A U C C
A AAA Lysine AUA ACA Threonine
A AAU Asparagine AUU ACU Threonine
A AAC Asparagine AUC ACC Threonine
The codon UUC encodes for the amino acid phenylalanine, the codon UCU encodes serine, and the codon CUU encodes leucine. So the correct answer is (a).
Organic substances known as amino acids have both amino and carboxylic acid functional groups. Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life.
A collection of instructions called the genetic code governs how DNA is converted into proteins. Codons, which are three-nucleotide sequences, are the building blocks of the code. Codons each represent each individual amino acid.
The codons UUC, UCU, and CUU all code for the amino acid phenylalanine. The third nucleotide in the codon determines the amino acid that is encoded. The codons UUA and UUG has different nucleotide from phenylalanine in the third position and thus code for leucine. The codon UCG encode for Serine.
Therefore, option (a) is right.

Answer: Sexual Intercourse (Sex)
Explanation: Sexual intercourse is when a biological male inserts their genitals into a biological women's genitals until semen, a liquid filled with fertilizing cells called sperm, travels into the women's uterus (a sack in the abdomen where a baby forms). If you are lucky, they will reach the eggs, produced by a woman every month after puberty, and a fetus (an unborn baby) will form over nine months. After those months, the woman's stomach will appear much bigger, until finally, the fetus is ready to be born. The woman's uterus will start squeezing out the fetus and the genitals will stretch, until finally, a baby emerges! The umbilical cord will be cut, tied, and become the baby's belly button. The baby should start to breathe, and the woman's organs will eventually go back to normal.
Which of the four factors that affect evolution apply to the finches that the Grants studied? Use
evidence from your research to support your answer. (15 points)
Answer:
Natural Selection in Real Time
"When we made the comparison between the size of the offspring generation and the population before selection, we found a measured, evolutionary response had taken place and it was almost identical to what we had predicted."
-Peter Grant
Darwin thought that evolution took place over hundreds or thousands of years and was impossible to witness in a human lifetime. Peter and Rosemary Grant have seen evolution happen over the course of just two years.
The Grants study the evolution of Darwin's finches on the Galapagos Islands. The birds have been named for Darwin, in part, because he later theorized that the 13 distinct species were all descendants of a common ancestor. Each species eats a different type of food and has unique characteristics developed through evolution. For example, the cactus finch has a long beak that reaches into blossoms, the ground finch has a short beak adapted for eating seeds buried under the soil, and the tree finch has a parrot-shaped beak suited for stripping bark to find insects.
The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.
The first event that the Grants saw affect the food supply was a drought that occurred in 1977. For 551 days the islands received no rain. Plants withered and finches grew hungry. The tiny seeds the medium ground finches were accustomed to eating grew scarce. Medium ground finches with larger beaks could take advantage of alternate food sources because they could crack open larger seeds. The smaller-beaked birds couldn't do this, so they died of starvation.
In 1978 the Grants returned to Daphne Major to document the effect of the drought on the next generation of medium ground finches. They measured the offspring and compared their beak size to that of the previous (pre-drought) generations. They found the offsprings' beaks to be 3 to 4% larger than their grandparents'. The Grants had documented natural selection in action.
While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that have the same size beaks. These factors together can add to the development of new species.
The Grants return each year to Daphne Major to observe and measure finches. They have been collecting data on the finches for over 25 years and have witnessed natural selection operating in different ways under different circumstances.
