For each cross, describe whether genetics or temperature determines the sex of progeny produced from eggs incubated at 35 degree
goldenfox [79]

<u>Answer and Explanation</u>:

In reptiles, there are two mechanisms of sex determination:

-Genetic mechanisms, determined at the fertilization moment

-Environmental mechanisms, which are temperature-dependent.

Temperature is an environmental factor that affects different processes in organisms at a molecular level, biochemical level, or physiological level. In reptiles such as lizards, snakes, turtles, crocodiles, among other, temperature influences their embryonary development, their growth, daily activities, reproduction rate, sex determination, and etc.

In lizards, it occurs that whenever eggs are incubated at low temperatures, between 22 º and 27ºC, they produce a higher percentage of males, while eggs exposed to higher temperatures, 30ºC and above, produce more females. There are only a few degrees of temperature at which exposed eggs produce males and females equally.

The importance of knowing the mechanism of organisms´ sex determination lies in how climate change may be affecting wild populations due to fluctuations in temperature.

In the exposed example, the first cross between ZZ males and ZW females, genetics is the mechanism that determines the sex of progeny produced from eggs incubated at 24 and 35 degrees celsius. While in the second cross between ZZmales and ZZ females, temperature determines the sex of progeny produced from eggs incubated at 24 and 35 degrees celsius. This is, eggs exposed to temperatures below 28ºC will produce only males, so there won't be any female in the progeny. But eggs incubated at 30ºC and over will produce females, as shown in the table.

The sensory cells associated with this sense actually hyperpolarize in response to their stimulus modality...
vaieri [72.5K]

Answer:

Vision

Explanation:

Sensory cells may detect the information like taste, touch, hear and vision by the presence of receptors located on their surface.

Hyperpolarisation may be defined as the change in the cell's membrane potential towards more negative. The sensory vision cells are associated with the hyperpolarisation of cells and makes the cells environment more negative  in response to the stimuli.

Thus, the correct answer is option (d).
