A certain strain of bacteria divides every 2 hours. If a colony is started with 80 bacteria, then the time t (in hours) required
Mamont248 [21]

Answer:

The time required for the colony to grow two million bacteria is 29.22.

Explanation:

Time required for the colony to grow can be calculated by the following equation:

t=2log(N/80)/log 2.

Here t is time, N = 2 million  (require bacteria population).

t=2log(2,000,000/80)/log2

t ≈ 29.22

Time taken by bacteria to grow is 29.22.

The ________ division of the nervous system carries motor commands to muscles and glands.
taurus [48]

The answer is efferent division. The nervous system acts as an input-output system. The afferent nervous system conveys signals to the brain following a stimulus. After processing of the information, the brain sends out a signal in response. This response is carried by the efferent nerve to the requisite organ involved in the response.

PLEASE HELP!!!! 30 points!!!! Start a discussion on Homeostasis. List 2 facts and 2 opinions.
kipiarov [429]

Answer:

facts: The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

opinions: Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.

Distinguish between declarative and procedural memory , and semantic and episodic memory , and explain how these are interrelate
kupik [55]

Three different LTM kinds exist: Three types of memory exist: (1) semantic memory, which stores factual information, such as the distinction between afferent and efferent nerves; (2) episodic memory, which stores details of specific experiences.

Such as your first day of work; and (3) procedural memory, which stores instructions. While episodic memory is the recollection of specific facts, semantic memory is the recall of generic facts. The two categories of long-term memory are declarative memory and procedural memory. Declarative memory is the ability to recall events, facts, and data. The memory of how to perform things is referred to as procedural memory.

2 C2H6 + 702 — 4 CO2 + 6H2O
Andreas93 [3]

We calculate the number of moles of water given its mass by dividing the mass by the molar mass.  

                              n water = (36.04 g) / (18 g/mol)  

                               n water = 2 mols

From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.

                               n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)

                               n oxygen  = 2.33 mols O2
