Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.
How many chemical bonds can each carbon atom form?
Answer:
It has four valence electrons, which it can achieve a full outer energy level which forms four covalent bonds. When its bonds only with hydrogen, it forms compounds which is called hydrocarbons. Carbon can be form in single, double, or triple covalent bonds with other carbon atoms.
Explanation:
The valency of carbon is four. Therefore, carbon can form four chemical bonds.
What is a chemical bond?It is the attraction between two atoms, they share or exchange electrons to form molecules or compounds is known as a chemical bond. They share electrons to fulfill their valency. The number of bonds depends on the number of valencies.
There are three types of bonds and that are covalent, ionic, and metallic bond. A covalent bond or molecular bond is formed by sharing of electrons, it occurs in non-metals. Ionic bonds are formed by exchanging electrons, it occurs in both metal and non-metal. metallic bonds are present between two metals. The covalent bond is the strongest bond.
There are four valencies in carbon. Therefore, it can make four bonds.

Which type of tissue carries messages?
A. Nervous tissue
B. Connective tissue
C. Muscle tissue
D. Epithelial tissue
SUBN
Answer:
Nervous tissue
Nervous tissue is responsible for carrying messages throughout the body. It is made up of specialized cells called neurons, which are able to transmit electrical signals. These signals allow the body to respond to stimuli and coordinate its movements. Hence option A is correct.
Connective tissue provides support and structure to the body. It is made up of cells that are embedded in a matrix of fibers. The fibers can be made of collagen, elastin, or other proteins. Connective tissue can be found in many different parts of the body, including the bones, muscles, and skin.
Muscle tissue is responsible for movement. It is made up of cells that can contract and relax. There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle.
Skeletal muscle is attached to bones and is responsible for voluntary movement. Smooth muscle is found in the walls of internal organs and is responsible for involuntary movement. Cardiac muscle is found in the heart and is responsible for pumping blood.
Epithelial tissue covers the body and lines internal organs. It is made up of cells that are tightly packed together. Epithelial tissue protects the body from infection and helps to regulate body temperature.

true?
A. Jessica inherited both genes from her father.
I
B.
Jessica inherited both genes from her mother,
C. Jessica inherited one recessive form of the
gene from each parent.
D.
Jessica inherited one dominant form of the
gene from each parent.
Answer:
D
Explanation:
Dominant and the recessive allele are the traits present in the genes that get inherited from the parent to their offspring.
The trait that is visible in the phenotype is called dominant while the trait that gets masked in the proximity of the dominant allele is called recessive.
The correct answer is:
Option C. Jessica inherited one recessive form of the gene from each parent.
This can be explained by :
The genotype of Jessica's eyes = bb (light)The genotype of her parents = Bb (dark eyes)See the attached image below for the cross:
The genes gets independently assorted and Jessica inherits the recessive form of the genes from both of her parent.
Therefore, Jessica inherited recessive gene one from each parent.

Explanation:
Ions:
Those atoms which lose or gain(transfer) electrons are called ions.
Ionic Bond:
Ionic bond is the bond formed between two oppositely charged ions due to the result of transferring of electrons.
1. How does the equations help explain the role of
producers in the ecosystem?
1. Producers create energy for other organisms to consume.
2. Producers convert sunlight into usable energy and Nitrogen.
3. Producers convert carbon dioxide and water into sugar.
4. Producers create Carbon dioxide for other organisms.
2. Aerobic Cellular Respiration is important to organisms because
1. It allows plants to produce sugar for food.
2. It releases the oxygen needed by plants for photosynthesis.
3. It converts sugars to usable energy that all organisms need.
4. It helps animals digest the sugars when they eat plants.
Answer:
1. Producers create energy for other organisms to consume.
2. It converts sugars to usable energy that all organisms need
Explanation:
All living organisms require energy, which they obtain by feeding on one another in an ecosystem. The series of feeding steps involved is called FOOD CHAIN. Food chain always starts with an organism called PRODUCER, which is an autotroph i.e. capable of producing its own food by using light energy from sunlight e.g plants. All other organisms in the food chain are directly or indirectly dependent on plants to get energy. This is because plants and other autotrophs create the energy that is being transferred as the food chain progresses.
2. Cellular respiration is an important phenomenon for all living organism because it is the metabolic process by which they obtain the usable energy by their cells i.e. ATP. Food molecules in form of sugar (glucose) eaten by organisms are broken down in the presence of oxygen (aerobic) to yield ATP molecules, which is the energy currency of every living cell. This energy is used to perform the organism's life activities.
