Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
Answer:
(F) 0.84
Explanation:
In this population of cats, there are two possible phenotype related to the tail length, long tail and short tail. According with the information given, we have the following distribution of phenotypes and genotypes in the population:
- TT -> long tail (180)
- Tt -> long tail (240)
- tt -> short tail (80)
The frequency of cats with long tail in the population can be calculated as the fraction of the cats that have the phenotype "long tail" in the population
<em>Fraction of long tail phenotype</em>=(TT individuals + Tt individual)/(Total population)=(180+240)/(180+240+80)=420/500=0.84
So, the fraction of cats with long tail in the population is 0.84
The correct answer is gastritis
Ulcers are being caused by bacteria which is known as Helicobacter pylori. It can be transmitted from one person to the other by exposure to vomit or fecal matter or by close contact.
The infection which is caused by the bacteria weakens the mucus which protects the duodenum and stomach then it allows acid to go through to the sensitive lining.
If it is not treated it can cause gastritis. The gastritis can occur either gradually or suddenly. It can also go ahead to the peptic ulcer disease and it can also come up with stomach cancer.
Some of the symptoms include nausea, burping, bloating, and vomiting.
Answer:
Option C
Explanation:
Given -
Pressure in the glomerular capillary 
mm Hg
Pressure in the capsular space 
mm Hg
The colloid osmotic pressure 
mm Hg
Also no plasma proteins are filtered by the glomerulus
In this scenario -
Net filtartion pressure is equal to
Pressure in the glomerular capillary 
Pressure in the capsular space colloid osmotic pressure
Substituting the given values in above equation, we get -
mm Hg
Option C is correct
