What is Respiratory System?

The respiratory system is a biological system that involves organs and structures in the body that are responsible for exchanging gases, particularly oxygen (O2) and carbon dioxide (CO2), between the body and the environment. It includes the nose, mouth, trachea, bronchi, lungs, and diaphragm.

In addition, other parts of the body, such as the nose, mouth, and pharynx, play a role in the intake and filtration of air. The respiratory system works in conjunction with the circulatory system to transport oxygen to cells and remove waste products, such as carbon dioxide. Different animals may have different adaptations and structures within their respiratory system, depending on their evolutionary history and ecological niche.

At one end, the tRNA has an anticodon of 3'-UAC-5', and it binds to a codon in an mRNA that has a sequence of 5'-AUG-3' through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.

Answer:

Uracil

Explanation:

In RNA Adenine pairs with Uracil

In DNA Adenine pairs with Thymine

Thymine dos not exist in RNA

Hope this helps ^^

Adenine in DNA pairs with uracil in RNA. Therefore option “D” is correct.

There are five types of the nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases.  Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.

DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil.

Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.

B. Industrial Revolution

Explanation:

Industrial Revolution brought technology that made producing things far simpler. Therefore, humans got more things to grow with.

Answer:

if the number of wolves increase the number of deer decrease

Explanation:

because deers are prey and wolves are predators

Wolves and deer show a prey-predator relationship. This indicates that as the number of wolves increases, the number of deer decreases and if the number of deer increases it means that the number of wolves has been decreased.

Prey-predator relationship is a type of association seen in the environment. In this relationship, one species feeds upon the other species. The prey species is the animal being fed on, and the predator is the animal who feeds. The predator prey relationship develops over time.

As the prey population increases, there is more food for the predators. So, after a small time, the predator population increases as well. This number keeps on increasing till sufficient food is available. As the number of predators keeps on increasing, more prey are captured. This results in the decrease in prey population.

The relationship between the wolf and its prey, deer is very complex.  Wolves population keep deer moving, which provides an ecological benefit for the health of the deer and plant species which are damaged from over-browsing. This keeps the number of species constant.

Dr. Leary argues that muscle contraction occurs because muscle fibers undergo a physical process of shortening. His explanation is a Reduction .

Skeletal muscle fibers become shorter as a result of the interaction between dense and thin strands within sarcomeres, which shortens the sarcomere. Summation happens when multiple cues are combined to cause a stronger muscular contraction.

The combination of several spasms into one continuous movement is known as tetanus. Recruitment is the process by which the quantity of motor units triggered in a muscle grows as the number of motor neurons involved increases.

The human skeleton is composed mainly of a substance called bone, and there are primarily four types of cells that make up bone. These are the osteoprogenitor cells, osteoblasts, osteoclasts and osteocytes. Their names all start with the prefix “osteo,“ which is the Greek word for "bone."

Explanation:

Mitosis is a process of cell division that involves several distinct stages: prophase, metaphase, anaphase, and telophase.

During prophase, the chromosomes condense, the nuclear envelope breaks down, and the mitotic spindle forms.

In metaphase, the chromosomes align at the center of the cell.

During anaphase, sister chromatids separate and move towards opposite poles of the cell.

Telophase is characterized by the formation of new nuclear envelopes around the separated chromosomes, followed by cytokinesis, where the cytoplasm divides to form two daughter cells.

Mitosis is the process of cell division that occurs in eukaryotic cells, leading to the formation of two genetically identical daughter cells. It consists of several distinct stages, including prophase, metaphase, anaphase, and telophase.

Prophase: Chromatin condenses into visible chromosomes. The nuclear membrane dissolves, and the centrosomes move to opposite poles of the cell, forming spindle fibers.

Metaphase: The chromosomes align along the equator of the cell, known as the metaphase plate. The spindle fibers attach to the centromeres of the chromosomes.

Anaphase: The spindle fibers contract, pulling the sister chromatids apart at the centromere. The separated chromosomes move towards opposite poles of the cell.

Telophase: The chromosomes reach the poles of the cell, and the spindle fibers disassemble. The nuclear membrane reforms around each set of chromosomes, forming two distinct nuclei.

Cytokinesis: Following telophase, the cell undergoes cytokinesis, where the cytoplasm divides, and the two daughter cells are formed. In animal cells, a cleavage furrow forms, while in plant cells, a cell plate forms to separate the daughter cells.

The stages of mitosis ensure the accurate distribution of genetic material to the daughter cells, allowing for growth, development, and tissue repair in multicellular organisms.

Extragenital gonococcal bacteremia can lead to gonococci causing damage to the joints and skin, as well as rare cases of meningitis in the brain and endocarditis in the heart. Gonococcal bacteremia refers to the presence of the Neisseria gonorrhoeae bacteria in the bloodstream, which can occur as a result of an infection in a non-genital site.

When gonococci enter the bloodstream, they can disseminate to different parts of the body and cause complications. In cases of extragenital gonococcal bacteremia, the bacteria may reach the joints, leading to a condition known as gonococcal arthritis, characterized by joint inflammation and pain.

The bacteria can also affect the skin, causing skin lesions and rashes. Additionally, although rare, gonococci can invade the central nervous system, resulting in meningitis, an infection of the brain and spinal cord. Furthermore, they can infect the heart valves, leading to endocarditis, an inflammation of the inner lining of the heart chambers and valves. These severe manifestations highlight the importance of prompt diagnosis and treatment of gonococcal infections to prevent complications and their associated morbidity.
