Answer:

not always confined to blood vessels and is under lower pressure than in closed circulatory systems

Explanation:

In an open circulatory system, blood is not always confined to blood vessels and is under lower pressure than in closed circulatory systems. This is because an open circulatory system is a system where blood, may be directly open to the environment in various places throughout the body such as the digestive tract, as opposed to being sealed in arteries and veins. Such a system is mostly found in insects and some animals such as snails or clams.

Summarize how the climate of the Miocene epoch impacted the evolution of hominins
andrezito [222]

Answer with Explanation:

The Miocene epoch was deeply characterized by<em> seasonal conditions</em>, such as having more colder winters in the northern areas.

In the <em>late Miocene</em>,<u> open vegetation system expanded. </u>These included<em> grasslands, woodlands and shrublands.</em> As a result, more primates inhabited the area. Several habitats became diverse from each other, thus allowing the species to adapt, including their locomotion. For example, the species who used to live on trees, turn towards living on land (terrestrial life). Certain animals also came about such as <em>pigs, giraffes, monkeys, etc.</em> Scavenging hominins also scattered. When it comes to hominins, a major type of locomotion evolved called "bipedalism." <u>This allowed the hominins to walk using the lower limbs (two feet).</u>
