Answer:

eukaryotic

Explanation:

Fungi (or Mushrooms) are eukaryotic and have a complex cellular organization.

Algae are eukaryotic cells, or cells that contain a nucleus, which makes them slightly more complex than bacteria

Protozoa are single-celled eukaryotic (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy.

Cystic fibrosis is genetic, meaning it can be passed from parent to child. What type of mutation causes cystic fibrosis? somatic

Tresset [83]

Answer: Germline mutation

A germline mutation is a mutation in the fully developed germ cells (sperm and ovum). These defective mutated cells fuse to form zygote. The zygote rapidly produces all somatic and germline cells in the offsprings which are also mutated. Therefore, mutation is transmitted from parents to offsprings. Cystic fibrosis is a result of germline mutation. This disease is hereditary in nature passes from parents to the offsprings. If a child receives CFTR (cystic fibrosis transmembrane conductance regulator) mutated gene from both the parents than the child will be affected by the symptoms of this disease. If the child receives a single copy of CFTR gene from either of the parent than the child will be the carrier of disease.The mutated gene may be present in the germline cells of the parent or on all the body cells.

Fill in the sentences to complete the statements about meiosis.

Debora [2.8K]

Answer:

23 chromosomes.

Explanation:

Meiosis is the process by which the chromosome number is halved during gamete formation. So chromosomes are 46 and get halved to 23 during the process of meiosis.

What is the difference between homeostasis and respiration

Verizon [17]

Answer:

Abstract

Respiratory homeostasis is concerned with the regulation of a blood gas composition that is compatible with maintaining cellular homeostasis. Provided that the lung-capillary exchange barrier does not prevent the exchange of gases, then blood leaving the lung will have oxygen and carbon dioxide partial pressures that are similar to the average values found in the alveoli. Alveolar ventilation establishes these values. If blood gas composition, especially of carbon dioxide, moves outside the homeostatic range, the change is detected by chemoreceptors and respiratory responses are promoted which change alveolar ventilation, alter alveolar gas composition and so reverse the change. Ventilation therapies provide the means of artificially restoring alveolar gas composition. In general terms, they do this by raising the partial pressure of oxygen within the alveoli either by using oxygen-enriched gas mixtures, or by improving the ventilation of alveoli using positive pressure.
