Y chromosomes do not code for color in tortoiseshell cats. A female cat that has only orange fur (XOXO) is crossed with a male cat that has only black fur (XoY). How many of the offspring will exhibit tortoiseshell coloring? 1 in 4. 2 in 4. 3 in 4. 4 in 4.

Answer:

2 in 4

Explanation:

If a female cat with orange fur (XOXO) is crossed with a male cat with black fur (XoY) then:

P: XOXO  x  XoY

F1: XOXo  XOY  XOXo  XOY

This means that half of the offspring will be females with tortoiseshell color  (XOXo) and other half  of the offspring will be males with orange fur (XOY).

The orbital cavities , nasal cavity, paranasal sinuses, and the oral cavity are all located in what region of the body
trasher [3.6K]

These are all part of the head or skull. The cavities of the skull surround and protect the brain and sensory organs. There are five kinds of cavities of the skull which are:


nasal cavity (paranasal sinuses is included here) - The nasal septum split the respiratory system into two lateral halves, the nasal cavity is also part of the respiratory system.


<span>cranial cavity - The large cranial cavity is split into a posterior cranial fossa and an anterior cranial fossa, a middle cranial fossa. Its function is to support the brain.</span>

<span>
</span>

oral cavity - The oral, or buccal, cavity (commonly called the mouth) is a cavity of the head rather than a cavity of the skull because of its fleshy and muscular floor.


orbital cavity - supports and defends an eyeball and its linked muscle, vessels, and nerves.


<span>middle ear cavity - From outer to inner, three small bones-malleus, incus, and stapes are situated within the middle-ear cavities in the petrous part of the temporal bones.</span>

Mice21 [21]

Correct Completed  Questions; Susan, a 67 year old female is experiencing ataxia, or poor muscle coordination. Doctors perform a neurological exam and they find that Susan is not positive for the Romberg test. Describe what these findings suggest about the sources of Susan's ataxia.

Answer:s

In order to test for balance and positioning(proprioception)   as a measure of  neurological function, or to test level   of intoxication alcohol  during driving, Romberg test is usually conducted,which can be negative or positive.It is generally used to investigate the cause of loss of motor control in individuals.

Explanation:

A positive result  showed that her  ataxia was due to loss of positioning due to loss of  sensory from sensory neurons.However if negative as in the case of Susan, then it  is to due to abnormality/dysfunctions   in the cerebellum, and not due to loss of sensory functions,
