Answer:
1/2
Explanation:
Father: is a heterozygote for this trait
. Meiosis: 1/2 is the frequency for the normal allele
Mother: has two recessive alleles (i.e., doesn't have the trait). Meiosis: 2/2 is the frequency for the normal allele
In consequence, the probability of having polydactyly is: (1/2) x (2/2): 1/2
Answer: B, D, and E.
Explanation:
Birds and reptiles are most closely related, Frogs are more closely related to birds than fish and fish are the most primitive are three statements that are correct because a cladogram is considering a diagram that is used in cladistics.
This type of diagram is there to show relations between organisms and in this case, it is true that birds and reptiles are related most closely, frogs are more closely related to birds and the fish( C is incorrect) is the most primitive( that is why answer A. is not correct).
A patient exhibiting respiratory distress as well as tracheal shift should be evaluated for pneumothorax.
<h3>What is pneumothorax? </h3>
This condition is also called collapsed lung. In this condition, the air from the lungs escapes into the pleural space around the lung.
This is caused due to an injury to the lung tissue and increased pressure on the lung tissue. This results in the leaking of air into the pleural space.
This condition can be traumatic or nontraumatic.
- Traumatic pneumothorax - When it is the result of an injury.
- Nontraumatic pneumothorax - When is the result of an already existing lung condition like chronic obstructive pulmonary disease (COPD).
Therefore, a patient exhibiting respiratory distress and tracheal shift should be evaluated for pneumothorax.
