Abiotic factors are things that aren't living that effect an environment, like pH (how acidic the soil is), the temperature, amount of light, and so on. These can effect a population by making it more difficult to survive, perhaps creating more competition over available resources and so on. So for example, if the soil is really acidic in an area, a population of plants may not be able to grow well in that environment.
Answer:
The flowering population is in Hardy Weinberg equilibrium.
Step by Step Explanation:
Total initial population size = 60
As both the populations are homozygous so the frequency of alleles will be,
P = 80/120= 0.66
q = 40/120= 0.33
The predicted frequencies for genotypes once the population has reached Hardy-Weinberg
p2 = 0.4356
2pq= 0.4356
q2 = 0.1089
The number of plants with each type of flower in a papulation of 420 is,
Homozygous dominant= 185
heterozygous= 185
Homozygous recessive= 50
Chi square analysis:
The observed values for red-flowered plants, pink-flowered plants, and white-flowered plants are not significantly different from the expected values predicted by Hardy Weinberg equilibrium.
Phenotype observed(o) expected (e) (o-e)2/e
Red 178 185 0.26
Pink 190 185 0.135
White 52 50 0.08
chi-square = 0.474
With 2 degree of freedom this chi-square gives a p value of 0.7 - 0.8, which is not significant.
When using the netcat command to test a network port, which option will provide output that is not useful for scripting, but is useful for the human eye?
The "-v" flag, which stands for verbose, is useful as it formats the command's output to be readable to human eyes.
This netcat command is necessary for human understanding as it stands for verbose and is used to test network ports.
However, it should be noted that it is not useful for scripting.
<h3>What is a Program Command?</h3>
This refers to the set of lines that are translated into machine-readable format and used to give instructions to the computer.
Hence, we can see that when using the netcat command to test a network port, the option that will provide output that is not useful for scripting, but is useful for the human eye is The "-v" flag, which stands for verbose

Answer:
The submucosa layer of the GIT contains blood vessels,so it can be the site of inflammation that leads to inflammatory bowel disease.
Explanation:
GIT has four layers , 1) mucosa the innermost layer 2) submucosa that is a layer of loose connective tissue that surrounds the mucosa. This layer also contains blood vessels, lymphatic vessels, and nerves. Glands may be embedded in this layer. 3) muscularis propia containing circular and longitudnal muscles 4)adventitia
As long as the blood vessels of the GIT are related, ischemia can cause inflammation that may lead to inflammatory bowel disease.
