Answer:
<em>In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.</em>
The nurse priority in this intervention is to asses the patient's condition of having to feel as if she is going to faint and the sudden change of color, because this is important for the nurse to note on before the client undergoes labor because this could be dangerous or could lead to complications when not assessed before she gives birth.
Answer:
The correct answer is a. resource partitioning
Explanation:
Resource partitioning is a strategy that species employ to avoid competition. It is based on the selection of different nutrition sources by different organisms that coexist in the same ecological niche, so there is no conflict between them. In the present case, each one of the eight species of woodpeckers feed on different trees, it means that each one select a different tree´s species or, if they select the same species, they use trees of different diameters.
A sex-linked trait is a trait that is carried by the X chromosomes in females but it is not expressed(the phenotype). Females are only carriers because they have two copies of the X chromosome [one of them carries the trait and the other does not]. Males who inherit one copy of the X chromosome often get the trait (because the trait is in either one copy or the other of the X chromosome) and express it while their Y chromosome would became recessive. Thus, only males express sex-linked traits such as hemophilia or color blindness
Answer:
The correct answer is a. absent spinal reflexes below the level of injury.
Explanation:
Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.
