Answer:
A) Pre-australopithecinerobust.
B) Australopithecinesgenus Homo.
Explanation:
Pre-australopithecinerobust.
The few findings indicate that he walked with his back straight, but the shape of the foot, with the big toe directed inward (as in the hands) instead of being parallel to the others, indicates that he should walk leaning on the outside of his feet and he couldn't travel great distances
Australopithecinesgenus Homo.
The first hominids that are certain that they were completely biped are the members of the Australopithecus genus, this type of hominin thrived in the wooded savannas of East Africa between 4 and 2.5 million years ago with remarkable ecological success, as evidenced by the radiation he experienced, with at least five different species scattered from Ethiopia and Chad to South Africa.
If my answer is correct, the conditions to which a reptile would be able to redirect blood is with the pressure of their lungs. This simple cardiac pump action enables the heart to force blood to other parts of the body.

Answer:
1. Heat tolerance: This will allow birds to maintain a body temperature around 10 degrees below the high air temperature.
2. Thermoregulation capabilities: Having thermoregulatory plasticity allows birds to adapt to warm conditions by increasing their evaporation rate and, therefore, increasing heat loss.
Explanation:
Today, it is extremely important for fauna to adapt to high temperatures that will become the "new normal" because of climate change and global warming.
Some species of birds have the ability to thermoregulate by behavioral or physiological processes. This will allow them to cope with increased temperatures and adapt to new climates. Other birds, however, are not able to withstand high temperatures, which could lead to high mortality and, therefore, increased population declines.
To adapt to these conditions birds should have a <u>high heat tolerance</u> threshold, <u>this will allow birds to maintain a body temperature around 10 to 15 degrees below the high air temperature</u>. For example, if the air temperature is around 30 ºC, their body temperature could remain below 20 ºC.
Also, they should have thermoregulation capabilities or plasticity. <u>This means that through different methods, such as reducing metabolism or increasing their evaporation rate, they will be able to cope by losing or exchaning heat with the environment.</u>
