Can people with different parents still have traits in common?
nirvana33 [79]
Technically, they can but you don't have to be related because you can have things in common with another person with are personality traits , and if they have different skin colors it doesn't matter , and you can still have many traits in common , because my sister is darker than me a lot but we still share same traits.

How do plants photosynthesize in winter? When they shed their leaves.​
butalik [34]

\Huge\green{\tt{✏Answer:}}

  • <em>Most trees do 'slow down' during winter, and deciduous trees that lose their leaves shut down photosynthesis entirely. Trees with needles (evergreen trees) that are retained over winter can actually photosynthesize during the winter.</em>

The minimum amount of energy needed to start a chemical reaction is known as:
nadya68 [22]

Answer:

The correct option is B. Activation energy

Explanation:

The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur, that is, the basic requirement for the reaction to proceed.

For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds are rejected. This requires energy (activation energy) and comes from the heat of the system, that, is, from translational, vibrational energy, etc of each molecule. If the energy is sufficient, the repulsion is overcome and the molecules are close enough for a rearrangement of the bonds of the molecules.

The concept of Activation energy was introduced by Arrhenius in 1889. Arrhenius suggested that molecules must prossess a minimum amount of energy to react. That energy comes from the kinetic energy of the clliding molecules. Kinetic energy serves to cause reactions, but if the molecules move very slowly, the molecules will only bounce when they collide with other molecules and the reaction does not happen. In order for the molecules to react, they must have a total kinetic energy that is equal to or greater than a certain minimum value of energy called activation energy.
