If, and only blood sugar levels rise past a certain point, the cells will release a hormone called insulin. Insulin acts as a/an

in a homeostatic feedback loop

Answer:

When blood glucose level rises beyond the threshold levels, the pancreas secrets hormones insulin. The latter ensures entry of  glucose into the cells through Glut transporters for cellular utilization, therefore reducing the blood levels., and promotes storage as glycogen in the liver and muscles.  

How ever if  the glucose levels drops below the  set point, an hormone glucagon is also produce by the pancreas to cause the liver o withdrawal and breakdown glucose storage as  glycogen back to glucose thus raising the blood glucose level back to the normal levels.

This is an example of negative feedback mechanism, because the increase in the input levels (blood glucose levels) brings about a counter  mechanisms (insulin secretions)as output , to reduce the  elevated   levels by promoting  entry into the cells,, thus bringing the levels to threshold levels.

Thus insulin is acting in a negative feedback mechanism to control blood glucose levels

____ [38]

Based on the given scenario, Jill is experiencing sensory adaptation. A sensory adaptation is where sensory system that a person acquires has ability to change in a way that they could adapt in certain situations. It is seen above as the hot water made her feel uncomfortable as she does not intend to sit on the tub while it is still hot and later on, she manage to be comfortable with the hot water after her sensory system has adopted to the stimulus which is the hot water in the tub. The sensory adaptation makes a person’s sensory system feel a change in response of a factor that will affect the system into leading it cope up with the factor affecting it.

xxTIMURxx [149]

The oldest true fossils are trace fossils called Stromatolites found in Australia, and dated between 3.5 to 3.3 billion years old.

Raphael Baumgartner and their team have finally uncovered evidence of organic matter in the ancient rock formations known as stromatolites found at the Dresser Formation fossil site in the Pilbara region of Western Australia. They detail their findings in a new article published in the journal Geology.

With a variety of methods, including scanning electron microscopy, scanning transmission electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, nano-scale secondary ion mass spectrometry, and stable carbon isotope analysis, the researchers examined the samples in thin slices.

According to the team's analyses, pyrite, a mineral with many tiny pores, makes up the majority of the stromatolites. Additionally, the pyrite contains nitrogen-bearing organic material and strands and filaments of organic material that closely resemble the remains of microbial biofilm colonies.

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.
