Archaea bacteria are different from eubacteria largely by​
telo118 [61]

Answer:

B)Genome

Explanation:

Archaea (Archaea) are single-celled microorganisms. Like bacteria, archaea lack a nucleus and are therefore prokaryotic. However, the differences at the molecular level between archaea and bacteria are so fundamental that they are classified into different groups. In fact, these differences are greater than there are, for example, between a plant and an animal. <u>Currently, archaea are considered to be </u><u>phylogenetically</u><u> closer to eukaryotes than to bacteria.</u>

Eubacteria are also known as "true bacteria", they are microscopic organisms that have prokaryotic cells. Because of their prokaryotic cells, they have a rigid cell wall, but they don't have mitochondria or other large organelles; They only have one chromosome, which is not found in the nucleus. Most of them reproduce asexually

Bang-up Motors will rent-a-wreck for $25 plus $0.15 per mile traveled. The rental cost is a function of the miles traveled a. Id
Kay [80]
A. The variables in the problem include the miles traveled, the cost to rent the car and the cost per mile traveled in the car. 
b. The rate of change in the problem is the amount of payment that is expected per mile traveled.
c.The y-intercept is the total cost of the miles traveled without including the deposit.
d. A straight-line function will work for this problem, where y = mx + c.
m = $0.15, c = $25 and x = total miles traveled. 
e. y = ($0.15)(1200) + $25
       = $180 + $25 
       = $205

Question 5 unsaved adding a unit to move a susceptible group enough to prevent metabolism is known as
mrs_skeptik [129]
<span>adding a unit to move a susceptible group enough to prevent metabolism is known as shifting.
These phenomena happen especially for liposoluble organism circulating in blood like drugs an hormones.
these molecules circulating blood can be divided into two forms : 
The free-form: which is the active part, it circulates freely in the blood, but are easily metabolised.
The bound form: it can be bound to other molecules from the organisms depending on its affinity like proteins (albumin, glycoproteins). this form is not active but is prevented from metabolism.

Competition for bounding proteins can happen between two drugs for example. If they have a different degree of affinity for proteins, then the most affine will displace the less affine from the protein and bound it, and that is call shifting</span>
