<span>To find the number of trees per hectare, simply divide the two figures together. 11,025 (the number of trees) divided by 3,150 (the number of overall hectares in the plot of land) gives a value of 3.5 trees per hectare.</span>
1. Red-shift, which is basically the Doppler Effect, but with light. Because stars in other galaxies appear to give off red light, this shows that they are moving away from us (Earth). Red light is on the far left of the Visible Light Spectrum, so things moving away from us appear to be red, while things moving towards us appear blue (the other end of the spectrum). This suggests that the universe is expanding all the time - and therefore it might have started from a single explosion - the Big Bang.
2. Cosmic Microwave Background Radiation (CMBR) has been found by scientists to be coming from all directions in space, and is suspected to be 'left over' energy from the Big Bang.

Alright, sure thing.
Explanation:
Grizzly bears, like black bears, eat a lot of vegetation, but they also eat more meat than their cousins. Grizzly bears hunt deer, elk, moose, and bison regularly, along with fish like salmon and trout. When meat is not available, they prefer to eat wild beans, nuts, grass, and tubers (a thickened underground part of a stem).
the answer is b And vote me brainlyist
Answer: Regulation of activity by higher brain centers.
Explanation: The autonomic nervous system is part of the peripheral nervous system and is responsible for involuntary actions that occur without control, such as breathing and heart rate.
The somatic nervous system is also part of the peripheral nervous system but is responsible for the transmission of signals to the skeletal muscles and from receptors of external stimuli.
The peripheral nervous system regulates systems such as the nerves and ganglia that are found outside of the brain and spinal cord. Thus the autonomic and somatic nervous systems differ, but both are not involved in the regulation of activity by higher brain centers.
