Answer:
A) One of the genotype i.e true breed white is lethal
B) No
Explanation:
A) Two hamsters with white spots are crossed, 2/3 of the offspring possess white spots and 1/3 has no spots.
This means that the two white hamsters would be carrier for the trait of no spot.
The ratio for offspring signifies that one of the offspring dies because of lethal genotype.
B) No, because the true breed for white spotting is lethal.
However, heterozygous white spotting can be detected.
Okay, so overall, the unicellular (presumably bacterial) organisms are going to be the most similar when talking about genetic material as the genetic material doesn't have to code for as many proteins as it would in a multicellular organism. For example, in humans, our genome codes for every protein in every cell in every tissue in every organ in every system in your body. However, unicellular organisms have to code far less as they have a very limited amount of proteins that they actually have to form. You'll have some differentiation when it comes to diet, but overall, the answer should be organisms A and C.
1. Intentionally taking species over to another place. Think smuggling animals over, you might think a squirrel is cute and bring it home from your trip to Paris back to the US. That squirrel can now be an invasive species. Don't be spiderman and take a banana on the plane!
2. Unintentionally carrying a species over. This can be on boat propellers, water tanks in boats, airplane wheels, etc. Getting animals stuck in transportation can become invasive.
Answer:
The digestive system works very closely with the circulatory system to get the absorbed nutrients distributed through your body. ... While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine.
The right answer is A. It requires more coal mining.
In order to manufacture synthetic gasoline, the Fischer-Tropsch process involves the catalysis of carbon monoxide and hydrogen to convert them to hydrocarbon. In this chemical process, the most common catalysts are iron, cobalt or ruthenium, as well as nickel, but the latter will tend to form methane CH4 (this is called methanation). The interest of conversion is to produce synthetic crude oil from coal or gas. This process has a very good yield but requires very heavy investments, which makes it economically vulnerable to downward fluctuations in the price of oil.
