The main difference between millennials and Gen z is that millennials include people born around the 1980s and 1990s, while generation z includes people being born during the mid -90's and mid-2000s. Generation z is also branded as generation y. Millennials are the demographic unit which follows Generation X. They are the final generation to be born in the 20th century.

Millennials are the first generation to grow-up absorbed in the era of digital technology, which has had an enormous influence upon the moods and the mores of the culture and its society. Generation z is the demographic which follows the millennials. Social media is of significant importance to them. They tend to live a very fast-paced life. Also, this generation has a less traditional family balance.

Codominance and incomplete dominance are the two types of dominance in genetics. These two types of processes contain alleles that are not dominant and are not recessive. The difference between them usually shows on the appearances as the carried trait. In incomplete dominance, the traits occur simultaneously as one in the offspring; while in codominance, the traits are also produced together at the same time. Now, what makes them different from each other?

It is simply that in incomplete dominance, the mixture of alleles is experienced as a trait; while in codominance, the alleles also exist at the same time but not as a trait. Actually, incomplete dominance usually exists in human beings or animals, while codominance usually occurs in plants. For example, the mating of a man with curly hair and a woman with straight hair producing an offspring with wavy hair is an example of incomplete dominance. A yellow flower and green leaves combining with another yellow flower and red leaves producing a yellow flower with red and green leaves side by side is an example of codominance.

The correct answer to this question is A, Number of times gum is chewed. A controlled variable is also known as a scientific constant. This variable is something in a scientific experiment which says the same and doesn't change throughout the process.

Throughout the experiment, there are different brands used. As a result, the size of the bubble varies as well. Throughout the five brands of gum, the only constant is the number of times the gum is chewed. Continuous variables have no significance to the person experimenting, but they can influence and have an impact on the results.

Ionotropic receptors are transmembrane molecules that can open or close a channel that would allow smaller particles to come in or out of a cell. The name gives this clue, but an “ionotropic” receptor allows ions to travel in and out. They are not always open; they are usually closed until a ligand or neurotransmitter binds to the receptor.

Metabotropic receptors do not open or close. They are instead linked to a small chemical called a “G-protein.” As soon as a ligand bind to this kind of receptor, it activates the G-protein, which then activates another molecule. That next molecule is called a “secondary messenger.”

The correct answer to this question is energy loss. As each level is progressed through, the organism on the scale will lose any energy that may have been gained from the previous trophic. Wasted material and life processes are the cause of energy loss. There are seven of them, and MRS GREN is how one can remember them.

M stands for movement, R, for respiration, S for sensitivity, G for growth, R for reproduction, E for excretion, and N for nutrition. All of these are reasons why, throughout the food chain, energy is wasted away and lost. If there were more than four, energy from all the tropics would be lost, and there would be no point to the food chain.
