Good afternoon, Nicol3713. I think the answer would be B - Rough ER because the bound ribosomes are attached to the rough ER or nuclear envelope. It should be right. Let me know if you need any more help. Have a great day!!
Answer:
The correct answer is they show weak positive gram staining reaction.
Explanation:
<em>Mycobacterium phlei </em>is a rod-shaped species of the genus Mycobacterium. They are acid-fast bacteria with mycolic acids rich cell wall due to which gram stain cannot penetrate easily and show light purple color while staining.
When gram staining is performed on the <em>M.phlei </em>, they take light purple color which indicates that it is a gram-positive bacteria and is related to Actinobacteria phylum of the gram-positive bacteria.
Thus, <em>M. phlei</em> is a gram-positive bacteria.
The relationship between the fungus and algae of a lichen is known as a symbiotic relationship.
In this kind of relationship, the two organisms work together to create one stable unit.
Answer:
The answer is D.
Explanation:
In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel.

Survivorship curve = so, first of all, it's a curve, as in a graph.
It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.
However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.
So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.
