How much does this is the ability of the body to maintain internal balance by changing external conditions how does the Respiratory system to help maintain homeostasis respiratory system help maintain homeostasis
Answer:
The internal balance of the organism is given by a functional organization between all the systems of the human organism, that is why no closed system, all interact with each other.
Homeostasis is known as: A set of self-regulatory phenomena, leading to the maintenance of relative constancy in the composition and properties of an organism's internal environment.
The homeostasis of the lung works by means of partial gas pressures, as we already know all gases go from areas of higher partial pressure to one of lower partial pressure, that is why when in our body CO2 increases and we enter a hypercapnia the system Release pulmonary CO2 excessively to the external environment, in contrast to oxygen when the partial pressure of oxygen is greater in the atmosphere than in our body, oxygen diffuses through the alveoli and goes to the affected capillaries for respiration.
This phenomenon explains the importance of oxygen in the atmosphere must always be greater than inside our body, since the lotratrario will not be able to breathe.
Furthermore, the respiratory system regulates situations of metabolic acidosis or alkalosis through hyperventilation or increased respiratory rate.
Explanation:
The respiratory system along with other systems acts in a connected way, it never acts alone, that is why they have receptors and signals between them.
Each one seeks to maintain the homeostasis of his own system in order to generate a balance and at the end of the day maintain the homeostasis of the TOTALITY of the organism

Can science be ethical if the scientists conducting the work are not ethical? How would
you determine this?
Answer:
Explanation:
ntific progress, the driving force for the majority of the changes witnessed in the 20th century, requires a critical mind, free of prejudice and open to new ways of thinking. The rapid development of modern science since the Renaissance is due mainly to the postulate that scientific theories should be independent of theological or religious beliefs. In the 17th and 18th century, knowledge was mainly exchanged through scientific academies which disseminated new theories and thus accelerated scientific progress. At the beginning of the 19th century, there was a remarkable rise in academic research at universities, also labelled ‘pure’ research. Scientists were not interested in practicalities and were not concerned with the technological applications of the results of their endeavours. They proclaimed the neutrality of science, stating that the advancement of knowledge could not be considered good or bad. In this context, science was not responsible for its applications, and even less for their subsequent use.

A scientist observed a phenotypic change in a mouse in her laboratory. This change was passed to the mouse’s offspring. What inference could the scientist make that would be supported by the observation?
a.
The phenotypic change is due to a mutation in a gamete.
b.
This mutation causes a disorder.
c.
This mutation has a positive impact on the mouse’s ability to survive.
d.
This mutation is the result of insertion of nucleotides.
Answer:
A
Explanation:
Mutations can occur in either cell type. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.

What is the structure of the virus?
Viruses are simple microscopic structures. They are infectious in nature with the ability to multiply only in living cells of animals, plants, or bacteria.
These are extremely small, even smaller than bacteria. They have a single- or double-stranded nucleic acid as genetic material. The genetic material can be in the form of DNA or RNA. It is surrounded by a protein shell called a capsid. Some viruses have an outer envelope that is composed of lipids and proteins outside of the capsid. They have various varieties of shapes.
RNA viruses and DNA viruses are the two main classes of viruses. A virus is inactive when it is outside of a living cell. It can only multiply within an appropriate host cell.
The virus can overtake the metabolic machinery of the cell to produce new virus particles called virions.
Therefore, the correct option is A.
