Answer:
Explanation:
The population density of an area is a demographic tool used to measure the number of organisms or individuals in a particular area.
It is expressed as;
Population density = 
The unit is expressed as organisms/km²
An area with a high population density is often not desirable as it can lead to pressure on amenities and infrastructure.
Planet with 1/2 the gravitational force as the earth. the effect of the mass and weight of the space probe is described below.
Explanation:
- At an altitude of 2642 km (approx. 1641 miles) above the Earth's surface, the gravitational acceleration will be 4.89m/s^2, which is half of 9.78 m/s^2 (the gravity at the surface).
- When the distance between the 2 objects is halved, the gravitational force between the 2 objects is doubled. when the distance between the 2 objects is doubled then the gravitational force doubles.
- Yes, a space probe that weighs 1000 pounds (excluding fuel) sitting in its launch vehicle on the launch pad will weigh much more from launch until the rocket's engines shut off. At that point it will become weightless. It becomes weightless because it's in free fall, even though it is still heading away from the Earth.
- In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. ... However, if we went from Earth to Mars, our weight would change because Mars has less gravity than Earth. Gravity is a force pulling matter together.
Answer: population of bacteria can survive and flourish by using light independence reactions
Explanation: So like the bacteria perform chemical reactions which produce energy for them

Explanation:
Lysosomes are membrane bounded organelles found in animal and plant cells. They vary in shape, size and number per cell and appear to operate with slight differences in cells of yeast, higher plants and mammals. Lysosomes contribute to a dismantling and re-cycling facility.
hope this helped! :D
