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.

In peas, the allele for round seeds (r) is dominant to the allele for wrinkled seeds (r). what would be the genotype and phenotype ratios of offspring from a cross between rr and rr individuals?
The genotype and the phenotype ratio of the cross between two homozygous recessive parents will be 100% homozygous wrinkled seeded-plants.
What is the genotype and phenotype?
The genotype of an organism is the complete set of its genetic material. Genotype of an organism can also be used to refer to all the alleles or variants of an individual which it carries in a particular gene or the genetic location.
Phenotype of an organism refers to an individual's observable traits, such as its height, eye color, plant characters, and blood type. An organism's phenotype is determined by both their genotype and the environmental factors.
In the cross between two homozygous recessive parents with wrinkled seeds, the genotypic and phenotypic ration of the F1 generation will be 100% homozygous recessive wrinkled seeded-plants.

Anorexia nervosa and bulimia nervosa are both eating disorders, but the main difference is that individuals with anorexia have a tendency to skip meals, while individuals with bulimia go through a cycle of binging (overeating) followed by vomiting. People with anorexia are usually extremely underweight and with an unhealthy figure, while the physical appearance of people with bulimia can be “normal” or sometimes underweighted.

A) a reduction in genetic variability.
B) an increase in genetic variation to accommodate changes in abiotic conditions.
C) no change in population size but an increase in favorable alleles.
D) a reduction in population size and an increase in genetic variability.
Genetic drift results in a reduction in genetic variability. Depending on the situation, there may be a reduction or increase in the population. So, the answer is A.
why does the warm air rise up and over the cold air at a cold front
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.
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.

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.

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.
Cells produce a variety of carbohydrates, including starch, glycogen and cellulose. The monomers of these large compounds are monosaccharides, such as the glucose molecule seen here. Cells assemble carbohydrates through dehydration synthesis, which means a(n) _____________ molecule is removed when the monomers are bonded together.
A) water
B) sugar
C) oxygen
D) carbon dioxide
When monosaccharides are joined to form disaccharides or carbohydrates, a water molecule is removed. This is called dehydration synthesis.
Cells assemble carbohydrates such as starch, glycogen, and cellulose through dehydration synthesis, in this reaction a molecule of water is removed when the monomers are bonded together. Thus, the correct option is A.
What is dehydration reaction?
Dehydration reaction or dehydration synthesis is the process in which the monomer units such as glucose molecules join together by forming glycosidic bonds to form the complex carbohydrates such as starch, glycogen, and cellulose.
The dehydration synthesis results into binding of the monomer units to synthesize a complex carbohydrate with the loss of a water molecule. Therefore, known as the dehydration synthesis. The synthesized carbohydrates can be reducing or non-reducing depending upon the proton and hydroxyl group present on the sugar.
Therefore, the correct option is A.
