Because it’s more likely that chance events will significantly change the frequencies of alleles in the population
Answer:
a. Stabilizing selection
Explanation:
Babies lower than 5.5lbs would suffer from various disorder because of low birth weight as their body would not be able to compete as well they would have weak immune system and malnourishment. Whereas high birth weight carry the equally above risk as their body wont be able to cope up and organs become insensitive to various hormones. for the survival the birth weight should be within a median range so that it would be favorable for themselves and surroundings.
Stabilizing selection occurs when a population stabilizes on a particular trait value and genetic diversity decreases. As in this example, an average baby weight has to favour against extreme variation for it's better survival.
therefore, this is an example of stabilizing selection.
Answer:
Behavioural
Explanation:
There are three components of behaviour that makes us act and think in a way that allows us to run our lives the way we feel comfortable and these are
- Behavioural
- Cognitive and
- Affective
In terms of Behavior, this component is the one that drives the way a person will behave towards a certain thing. In this case, an undesired pregnancy. This will be for the benefit of the person in long or short term and will provoke them in a way to take precautionary measures.
Answer:
107 m/s
Explanation:
speed = distance / time taken
speed = 0.914 / 0.00854
speed = 107.0357 m/s
round off ( 107.0357 ) = 107 m/s
D) competition for resources is greater
The more in the population, the more resources needed. If they run out of resources, the population decreases. They are competing to stay alive. I hope this helps!
