Answer:

c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.

Explanation:

Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.

Eddi Din [679]

Answer:

Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes

Explanation:

The specificity of the antibiotics to inhibits some  bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition  antibiotics are designed to  have a significant  destructive  effects on  the mechanisms of biochemical reactions in bacteria and its  physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus

Exercising causing ___________
goldfiish [28.3K]

Answer:

c. increase HDL levels

Explanation:

Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.

Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.

Explanation:

Green roofs are also known as eco-roofs in which a vegetative layer is placed on a flat or sloped roof. Beneath this roof, a waterproofing system is also placed. These roofs have been categorized based on the length on the plantation. Some of the major benefits of green roofs are –  

a) They are climatically oriented as they play an important role in regulating the temperature and purifying the air.

b) They prevent flow of rain water and saves energy.

c) Regulate the internal ambient temperature and urban heat island affect

d) Prevent particulate matter from the air  

Hence, option D is correct
