Answer: The complementary base pairing helps in proper pairing of the bases.
Explanation:
The complementary of base pair shows that the adenine will only bind to the thymine and the guanine will only bind to the cytosine and with any other base pair.
So, the template no matter how long it is, the adenine in them will bind to the thymine and the cytosine will bind to the guanine.
The bonds in between are double hydrogen bond in case of adenine and thymine and triple hydrogen bond in case of guanine and cytosine.
This aids in pairing of 6 billion bases during the time of DNA replication in human beings.

The function of that macromolecule: it is the macromolecule that contains the genetic information of living organisms.
How it is related to forensic science (i.e. provide an example and explain its use in forensic science): DNA is used in forensic science for many applications, one of them is to identify a criminal form the samples of hair, saliva, blood etc. collected from a crime scene.
Explanation:
A macromolecule is a large molecule that is made up of smaller subunits.
DNA is a macromolecule that is made up of nucleic acids.
DNA is most commonly used in forensic science as it is commonly present in the samples such as saliva, hair, blood, etc. that can be easily obtained from a crime scene.
This DNA can then be used to match the person with the help of DNA fingerprinting.
The advantage is that even a small amount of DNA in the samples can be utilized as the technique of polymerase chain reaction (PCR) exists.

List and describe the role of the 3 types of rna.
There are three RNAs with a role in the synthesis of protein.
mRNA, or messenger RNA, is the link between a gene and a protein. The main role of this ribonucleic acid is in transcription (”reading“) of DNA. The DNA is transcribed by RNA polymerase, and the resulting product of this process is mRNA. This form of RNA can be modified post-transcriptionally with methylguanosine caps and polyadenosine tails. RNA carries the genetic information which is copied from DNA and the information has a form of three-base code (“words”), codons. Each of these codons specifies a particular amino acid.
tRNA or transfer RNA is the molecule with the main function in translation by "decoding" the mRNA message during this process. Each type of amino acid has its own type of tRNA and also has a three-base sequence (anticodon) that can bind complementary with the codons in the mRNA.
rRNA or ribosomal RNA is a main component of ribosomes. rRNA associates with a set of proteins to form ribosomes which catalyze the assembly of amino acids into polypeptide chains (protein).
There are also a few more types of RNA which have a regulatory function like, microRNA or siRNA.

What is the significance of mendel's experiments to the study of genetics?
The significance of Mendel's experiments in the study of genetics is Mendel's revelation significantly increased our understanding of how genes are passed down and inspired the creation of novel experimental techniques.
Who was Gregor Mendel?Gregor Mendel uncovered the basic principles of inheritance through his study on pea plants. He concluded that genes are inherited from each parent as separate, paired units.
Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the children. Mendel created three laws of inheritance that characterized the transmission of genetic features through pea plant breeding before anybody knew genes even existed.
Mendel's revelation significantly increased our understanding of how genes are passed down and inspired the creation of novel experimental techniques.
Therefore, Mendel's discovery greatly expanded our understanding of how genes are handed down and encouraged the development of novel experimental procedures, which is the relevance of Mendel's experiments in the study of genetics.

which situation is associated with shear?
A. new rock formations
B. convergent boundaries
C. frequent shallow earthquakes
D. volcanic mountain ranges
Answer:
Frequent shallow earthquakes
Explanation:
Shear is the response of a rock to deformation usually by compressive stress and forms particular textures.
During an earthquake when the earth shakes it produces a super shear earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity.
The mechanisms of shearing depend on the pressure and temperature of the rock and on the rate of shear which the rock is subjected to.

Why does DNA need to be copied into mRNA?
mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.
The transfer of information in a DNA strand to a new molecule of messenger RNA is known as transcription. Thus, the process of transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. However, DNA is copied into mRNA because mRNA will serve as reference book that contains information as the DNA and its sequence is complementary to the DNA template.
The hypothalamus, in addition to the cerebral cortex, is in control of emotional responses. the hypothalamus, in addition to the cerebral cortex, is in control of emotional responses.
a. True
b. False
The answer is A; true. Emotions are controlled by the limbic system of the brain that is composed of The amygdala, The hippocampus, Regions of the limbic cortex, and The septal area. These regions work in conjunction with the hypothalamus, thalamus and cerebral cortex in the regulation of feelings such as anger, fear, and pleasure.
Final answer:
The statement is true. The hypothalamus is a critical component of the limbic system, regulating emotional responses by interacting with the cerebral cortex, specifically through connections with the amygdala.
Explanation:
The statement that the hypothalamus, in addition to the cerebral cortex, is in control of emotional responses is true. The hypothalamus plays a crucial role in the limbic system, which is heavily involved in regulating emotions. It receives signals from the amygdala, a structure within the temporal lobe of the cerebral cortex known for its involvement in processing emotions. When emotional responses like fear or anxiety are triggered, the amygdala sends signals to the hypothalamus via the medial forebrain bundle, which can stimulate a fight-or-flight response and influence the release of stress hormones through control of the endocrine system.
The hypothalamus is also responsible for maintaining homeostasis and regulating body functions, such as food and water intake, energy expenditure, and body temperature. Furthermore, its connections with other parts of the brain, including the olfactory cortex and septal nuclei, allow it to regulate emotional states and physiological reactions. The cerebral cortex, particularly its frontal regions, also contributes to the modulation of emotional behaviors through higher cognitive processing and regulation. Therefore, both the hypothalamus and the cerebral cortex have integral roles in the complex network that governs emotional responses.

What were the conditions like on early Earth? (Be specific)
On early Earth, conditions were harsh with extreme heat, lack of oxygen, strong radiation, and significant geological upheaval and volcanic activity. The atmosphere was anoxic and filled with reduced inorganic chemicals, quite different from today's environment. The earliest life forms, prokaryotes, were adapted to these extreme conditions.
Conditions on Early Earth
The conditions on early Earth were very different from what they are today. The atmosphere was anoxic, meaning it lacked oxygen, and primarily composed of reduced inorganic chemicals. This reflects a stark contrast to the oxygen-rich atmosphere we have now. It is believed that early cells that formed on Earth were adapted to survive in these harsh conditions. These conditions include extreme heat, the absence of oxygen, and exposure to strong radiation.
Additionally, the geological landscape of early Earth was characterized by tumultuous geologic upheaval and frequent volcanic activity, which would later play a crucial role in the development of the planet's surface and atmosphere. The early atmosphere, largely made up of gases like methane, ammonia, and water vapor, differed vastly from today's nitrogen and oxygen-rich atmosphere.
The first organisms, known as prokaryotes, appeared during this tumultuous time and were well-suited to the high-temperature environments possibly around hydrothermal vents and protected from strong radiation beneath the ocean depths or Earth's surface. Evolution eventually led to microbial mats, which are considered to be some of the earliest forms of life, dating back to about 3.5 billion years ago.
