Answer:
The consumption of a drug that inhibits or block the enzyme primase will have problems for the replication of DNA, since it is not possible to synthesize a new strand without this enzyme.
Explanation:
During DNA replication, the enzyme primase is responsible for synthesizing the primers, RNA fragments necessary for the DNA polymerase III to synthesize the new DNA strand.
If for any reason the action of the primase is blocked, the primer could not be synthesized and the effect of DNA polymerase III would be null, so the new DNA strand could not be synthesized.
In DNA replication, the primase contributes to the formation of small fragments of DNA, by the action of polymerase III, which are called Okazaki fragments. These fragments will require the action of another enzyme, ligase, in order to form a continuous DNA strand.
The correct answer is: right ventricle
There are two types of blood circulation:
1. Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released and O2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.
2. System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from all tissues is then returned through the veins back to heart.
Blank 1: <u>hawks and owls</u>
Explanation: Tertiary consumers lie on the top of the food web or pyramid. They are dependent on other organisms for their food. These are carnivores by mode of nutrition. Here, the food web sequence would be like-
small birds----->snakes----->hawks and owls.
That's why they are the tertiary consumers.
Blank 2: <u>decomposers
</u>
Explanation: The organic matter of dead plants and animals is decomposed by decomposers. They breakdown the complex organic compounds into simpler substances.
Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.
