A population of plants growing in a field is examined over a period of years. The plants have either white or yellow flowers.
What best explains the observations?
A. White flowers increase the plant's fitness, so the population is under directional selection.
B.Yellow flowers increase the plant's fitness, so the population is under directional selection.
C.Yellow flowers increase the plant's fitness, so the population is under disruptive selection.
D.White flowers increase the plant's fitness, so the population is under disruptive selection.
Answers
Thebest explanation for the observation is that white flowers increase the plant's fitness, so the population is under directional selection.
What is genetic variation?Genetic variation refers to the differences that exists in the genes of organisms of the same species or different species.
The gene for flower color in the plants has two alleles for yellow and white flower color.
Over time, the proportion plants with white-colored flower increased while that of yellow decreased.
Therefore, the best explanation for the observation is that white flowers increase the plant's fitness, so the population is under directional selection.

This treaty was signed in the year 1987 and became effective form 1989.
• Since the time that this treaty has come into force, there has been a significant improvement in the ozone hole that was observed over Antarctic as it's size has decreased.
• This improvement has been possible because the treaty helped to phase out chemicals such as chlorofluorocarbons, carbon tetrachloride, etc. that are responsible for ozone hole depletion.

A farmer is struggling to control the population of a certain insect on his farm. After researching population control techniques, he discovers that a particular bird is a predator of this insect. The farmer purchases a number of these birds and releases them onto his farm.
How might the farmer’s action most likely have a negative impact on the ecosystem?
The birds will increase biodiversity of native plant species.
The birds will pollinate native species, increasing genetic variation.
The birds will consume beneficial insects, as well as the pest species.
The birds will mate with native birds and create a new species.
Answers
One of the effects of the farmer's action on the ecosystem would be that the birds will consume beneficial insects along with the pest species.
Ecological effects of biological pest controlBiological control of pest requires that a living organism that will prey on the pests are introduced into the ecosystem
However, the most effective biological control of pests has to do with introducing biological agents that are very specific in action.
Using a bird species to control insect pests may lead to beneficial insects being consumed along with the insect pest in the ecosystem. The loss of beneficial insects will create a new problem in the ecosystem.

Nick is smiling even though he does not feel happy. After a short time he feels happier. The best explanation for Nick's change in mood is
O bottom-up processing
o facial feedback
selective encoding
O justification of effort
Answers
o facial feedback
When someone replicates a emotion, they tend to feel it
Nick is smiling even though he does not feel happy and after a short time he feels happier too. This change in mood is due to facial feedback. Therefore, the correct statement is option B.
What is the facial feedback mechanism?Facial feedback is a psychological theory that suggests that the expression on a face of a person can influence their emotions and mood also. Therefore, when a person smiles even when they are not feeling happy, it can trigger positive emotions in the brain that change in mood.
Nick is smiling even though he is not feeling happy. Therefore, this act of smiling can trigger positive emotions in his brain and changes his mood because of the facial feedback mechanism.
However, bottom-up processing is the processing of sensory information from the environment to create a perception, while selective encoding is a process of selectively attending to and encoding certain aspects of a stimulus while ignoring others.
Therefore, Nick is smiling even though he does not feel happy and feels happy after a short time due to facial feedback.
