Cell wall - Adds structural support to the cell. Holds the cells together
Cell membrane - Serves as a barrier to the cell and allows more nutrient and molecules to move in and out of the cell without letting things that can harm the cell in. 
Outer membrane - Serves the same basic functions a the cell membrane. (Depending on how complicated the class your in is, I would visit this website for more information... https://en.wikipedia.org/wiki/Bacterial_outer_membrane )
Pili - Help the cell move and attach the bacteria to surfaces are other cells. 
DNA - Contains the genetic instructions on what the cell can physically do, operate, and reproduce. 
Flagellum - Helps the cell move. It kind of acts like a propeller for the cell so that it can move around.

how does the earth evlove around the sun while the moon evlolves around the earth with out those two planets colliding
ICE Princess25 [194]

Answer:

This is a rather complicated thing to explain so I'll try my best. To put it in simple term the sun has whats called a SOI (sphere of infleunce) and anything inside of this is effected by the gravity of that planet or sun in this case. The earth is inside of this sphere of influence. The earth has a constant velocity that is making it move away from the sun but since it's in the suns SOI the path in which the earth moves is changed in a way that causes it to spin around the sun. The same thing is happening with the moon. I'm not 100% sure on this but I think the reason the moon does not just fly away towards the sun is because it is closer to earth and is more effected by earths SOI. Hope this cleared things up for you.

elixir [45]

Answer:

The answer is: a. Climacteric

Explanation:

Climacteric is the time in the midlife of a woman that starts with the diminution in ovarian activity (less production of estrogen and progesterone) until the end of ovarian function. It is the compilation of gradual changes of ovarian function that happen before the menopause (cessation of menses) and continue for a while.

The phases of the climacteric are pre-menopause, menopause and post-menopause. During the pre-menopause, hormonal changes will take place, there is a decrease in estrogen and progesterone production.

What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP
Nady [450]

The given question is incomplete, the complete question is:

During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions. Condition Rate of carbon dioxide produced (mL/min) Germinating peas, 10ºC 0.01 Germinating peas, 20ºC 0.02 What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production. Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production. Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC. The rate of cellular respiration cannot be measured without knowing the rate of ATP production.

Answer:

The correct statement is that at 20 degree C, the germinating peas exhibits a higher rate of cellular respiration in comparison to the germinating peas at 10 degree C.

Explanation:

The process of respiration results in the production of carbon dioxide, respiration refers to a chemical reaction that generates water, carbon dioxide, and energy by undergoing oxidation of the glucose molecules. This phenomenon plays an essential role in the life of the organisms for obtaining energy from the food they consume to perform daily activities.  

From the question, it is evident that the peas, which were germinating at 20 degrees C exhibit a higher rate of cellular respiration as they are generating 0.02 milliliters of carbon dioxide in a minute, while on the other hand, the germinating peas at 10 degrees C are giving rise to 0.01 milliliters of carbon dioxide in a minute.
