Answer:
According to Punnett Square, what can be concluded from Huntington's disease is that the disease is autosomal dominant.
Explanation:
Huntington's disease is characterized as a neurodegenerative condition, which affects body movements and progressively decreases some higher brain functions.
Inheritance plays a determining role in Huntinton's disease, being a disease transmitted from parents to children with an autosomal dominant pattern, that is, all <u>individuals with the defective gene (H) will have the disease</u>, while the <u>absence of the gene (rr) also guarantees the absence of this condition</u>.
The other options are not correct because:
- <em>Inheritance of Huntington's disease is not sex-linked.
</em>
- <em>The allele that determines the Hungtinton's disease is not recessive.</em>

Answer:
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Explanation:
dang it.
For staining flagella of bacteria use actively motile organisms 20 to 24 hours old, allow to diffuse in sterile water 20 to 30 minutes, transfer droplets of the suspension to clean slides and let evaporate without spreading. Then treat 2 to 4 minutes with the following mordant: tannic acid 10 or 20%, 50 cc.; ferric chloride 5%, 10 to 15 cc.; carbol fuchsin (Ziehl-Nielson), 5 cc.; hydrogen peroxide 3%, 6 to 8 cc. Wash and stain 2 to 3 minutes with a mixture of basic fuchsin, saturated alcoholic, 10 cc.; anilin oil (1 part) and 95% alcohol (3 parts) mixed, 5 cc.; distilled water, 30 cc.; acetic acid, 4%, 1 cc. Wash thoroly with water.
<span>Scientists consistently link two catastrophic events with the five major mass extinctions recorded throughout Earth's history. These two events are
A) global ice ages and the impact of asteroids.
Global ice ages led to the extinction of many populations over time, whereas when asteroids hit Earth, dinosaurs disappeared, among other species.
