Answer:

The trait must make the individual more fit to survive. True

Explanation:

Darwin proposed that genetic variations are present in natural populations. Some genetic traits become beneficial under the changed environmental conditions. The organisms with these genetic traits are able to survive and reproduce better than the organisms that lack them. This results in an increased proportion of the beneficial genetic traits in the population over generations as the individuals having those traits reproduce more.

The presence of antibiotic resistance is a beneficial genetic trait that allows bacteria to survive in the presence of antibiotics. Natural selection favors the bacterial having antibiotic resistance and increases their proportions in the population over generations.

Cells will usually divide if they receive the proper signal at a checkpoint in which phase of the cell cycle? see concept 12.3 (
NeTakaya
The correct answer is the interphase.

The cell cycle consists of three phases: the interphase (G1, S, G2) the mitotic (M) phase, and cytokinesis. <span>The first checkpoint of the cell cycle is G1 checkpoint which is between G1 and S phase when cell checks its size, nutrients, molecular signals, DNA integrity. The second checkpoint is G2, just before the mitotic phase, when cell checks DNA integrity and DNA replication. Those two checkpoints are the ones before division, other like M checkpoint is during the mitosis.</span>

Is the statement "I joined the science club to make my parents happy" intrinsic motivation
Bess [88]
Depends on whether the person is talking to themselves, or someone else.
If they are talking to themselves, it is indeed intrinsic motivation, as they are convincing themselves they are also happy and motivated to join the science club as it makes their parents happy.
If they are talking to someone else, it would not be intrinsic motivation. This is because they are merely telling someone that they're doing something to make their parents happy.
As it is a statement, on the whole I would say, no. It is not intrinsic motivation.
