What are two reasons bees are important beyond making honey

zhenek [66]

Answer:

Bees are perfectly adapted to pollinate, helping plants grow, breed and produce food. They do so by transferring pollen between flowering plants and so keep the cycle of life turning.

The vast majority of plants we need for food rely on pollination, especially by bees: from almonds and vanilla and apples to squashes. Bees also pollinate around 80% of wildflowers in Europe, so our countryside would be far less interesting and beautiful without them.

As hominids evolved, their eyes increased in size and became more forward facing. Which of the following can be inferred from th

lisabon 2012 [21]

The answer is Hominids became more dependent on vision over time and less so on their other senses. <span>This statement is related to the general decrease in the importance of smell and the increasingly significant use of vision. The stereoscopic (three-dimensional) vision and the appropriate perception of the resulting depth enabled the development of visual acuity over time.</span>

Which energy is affected by an object's mass?

statuscvo [17]

Answer:

A potential

B kinetic

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

$K.E = \frac{1}{2}MV^{2}$

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

$P.E = mgh$

Where, P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Both potential and kinetic energy is affected by an object's mass.
