What evidence can be examined when determining common ancestry amongst hominids?
mars1129 [50]

We examined the biogeographic patterns implied by early hominid phylogenies and compared them to the known dispersal patterns of Plio-Pleistocene African mammals. All recent published phylogenies require between four and seven hominid dispersal events between southern Africa, eastern Africa, and the Malawi Rift, a greater number of dispersals than has previously been supposed. Most hominid species dispersed at the same time and in the same direction as other African mammals. However, depending on the ages of critical hominid specimens, many phylogenies identify at least one hominid species that dispersed in the direction opposite that of contemporaneous mammals. This suggests that those hominids may have possessed adaptations that allowed them to depart from continental patterns of mammalian dispersal.

Describe the Earth's crust, mantle and core. Include the thickness, composition, temperature and pressure of each layer in your
Alja [10]
Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust..The crust is made of solid rocks and minerals.

The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up 84% of Earth's total volume.

The core lies beneath the cool, brittle crust and the mostly-solid mantle. ... Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle.1

Match the human activity with its effect on groundwater.
fgiga [73]

Answer:

3. Household wastes

2. Landfills

1. Agriculture

Explanation:

The groundwater is more and more contaminated, and there are numerous ways in which the contamination occurs. The causes of pollution mainly come from the human activities. The humans use all sorts of chemicals, fossil fuels, paints, and often there is waste from them, waste that is dumped into the drainage, and occasionally reaches the groundwater. The leaking of linings also manages to cause lot of damage, as very often it can reach the groundwater, causing heavily contamination of it. The agriculture, as much as it is needed, is a big polluter too, and the pollution mainly comes from the usage of pesticides, herbicides, and fungicides, which wash through the soil and end up in the groundwater.

If a plant is living in a cold environment, which physiological change would help the most with the cool temperatures?
Novosadov [1.4K]

The plant species that live in the colder environment have some adaptations that makes them survive in that conditions

These plants have a well developed vascular system due to which they have the ability to trap every inch of sunlight available for the process of photosynthesis.

Some of the plants shed their leaves and stay in dormant conditions.

Evergreen trees have thick waxy coating that prevents the loss of water.

The plants that grow in arctic regions are small and they grow close to the ground in a specific shape that helps them to shed snow from them.
