b. respiratory anthrax has the least mortality rate .
What is anthrax infection?Anthrax is a serious infectious disease caused by gram-positive, rod-shaped bacteria known as Bacillus anthracis. Animals both domestic and wild are frequently impacted worldwide by this natural occurrence in soil. If people come into contact with diseased animals or contaminated animal products, they could become ill with anthrax.
The most harmful effects of anthrax include damage to numerous organ systems as a result of your body's inability to respond to infection correctly (sepsis) inflammation of the fluid and membranes that surround the brain and spinal cord, which can cause fatal hemorrhagic meningitis and severe bleeding. Some anthrax infections occur when people breathe in the spores of the bacteria.

Without genetic variation, natural selection would not be possible. Explain why.
Answer:
Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously exited in the population. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population. If every giraffe had the same neck length, there would be nothing to change and they would never have a long neck by now.

Answer:
True
Explanation:
Vocal cords are bands of smooth muscle tissue located in the larynx. When air passes through, the vocal cords vibrate.
What is the structure of a virus?
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
A virion consists of a nucleic acid core, an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell. The capsid is made up of protein subunits called capsomeres. Viruses may also contain additional proteins, such as enzymes

Which explanation describes why males are more likely to exhibit sex-linked disorders than females?
A male with a mutation in a gene on the X chromosome is typically affected with the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females.

Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)
Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.
The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.
The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.
What is the mechanism of pulmonary ventilation?The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.
Inhalation process in pulmonary ventilationThe inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.
The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.
Exhalation process in pulmonary ventilationThe exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.
Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

how are viroids different from viruses
Answer:
We are all familiar with the basics of viruses: These particles infect living cells and wreak havoc throughout the body. But viruses aren’t the only villains around causing chaos in living things. Other infectious agents called viroids and prions — which are also tiny but powerful — can take down both plant life and entire animals.
Viroids are free RNA molecules of low molecular weight without any protein coat, while viruses can have either RNA or DNA molecules encapsulated in a protein coat. Viroids are smaller in size than viruses.
Viroids not made of cells.
Viroids don’t transform energy.
Viroids can’t reproduce on their own.
