Answer:

When glucose is high, camp is low : cap doesn't bind the lac operator, and RNA polymerase doesn't bind the lac promoter.

Explanation:

The lac operon is a molecule responsible for the rapid transport of lactose in Escherichia coli, mainly, but it can be found in other bacteria. This molecule is essential to regulate several factors within the bacterial cell, however the main factor regulated by it is the availability of glucose and lactose in the environment. WWhen glucose is high, camp is low: cap doesn't bind the lac operator, and rna polymerase doesn't bind the lac promoter.

When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent.  The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.

Why is the rate of movement of the air bubble not exactly the same as the rate of water loss from the plant?
OLEGan [10]

Answer:

Both depends on different factors.

Explanation:

The rate of movement of the air bubble is not exactly the same as the rate of water loss from the plant because both depends on different environmental factors. The higher rate of movement of the air bubble occurs due to removal of pressure while on the other hand, the rate of water loss from the plant occurs due to temperature. So both air bubble and transpiration process depends on different environmental factors.

How do mass extinctions affect the rate of evolutionary change?
ANEK [815]

The role of mass extinction in evolution. At the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendant species they might have given rise to. ... But mass extinction can also play a creative role in evolution, stimulating the growth of other branches.

Which does NOT occur in telophase? Cytokinesis is under way. The nuclear envelope is being reconstructed. The centromeres split
Lostsunrise [7]

Answer:

The centromeres split apart

Explanation:

Telophase is the last sage of cell cycle that ultimately result in the formation of daughter cells. The chromosome become more condense in this stage.

The nuclear envelope reconstructed and the cyotkinesis is under way in the telophase. The nucleolus reforms in the telophase. The centromeres are split part in the anaphase stage of the cell cycle.

Thus, the correct answer is option (3).

Explain the purpose of a quick body response like pulling a hand away from a hot stove
raketka [301]
The purpose of a quick body response is from your brain. Your brain has a nervous system that can tell you to do things that you should.
In this case, Pulling your hand away from a hot stove could be dangerous, so you nervous system quickly reacts to take your hand away from the stove.

I need helping finding 5,6,7&8

5. Contour interval of the map is 20m

6. Highest elevation of the map is 160m

7. Lowest elevation of the map is 20m

8. Distance between the top of the mountain and the depression is 9.5km approximately

Explanation:

Contours are the geographical lines representing a boundary or border of a place.

5) Contour interval of the map

We see that throughout the map contour lines are spaced at an interval of 20m E.g. 160,140,120,100 etc. Hence, the contour interval of the given map is 20m

6) The highest elevation of the map- Highest elevation of the map would be shown by contour lines of the highest order. Looking at the map we find that section” A” at the left-hand side is marked with 160m contour lines. Hence, the highest elevation is 160m

7) Lowest elevation for the depression- For lowest elevation, we have to look at the lowest contour lines. We see that maximum depth in the depression is marked by 20m contour lines. Hence the lowest elevation for the map is 20m

8) Kilometres from the top of the mountain to depression- For this, we need to calculate the distance between the mountain head and the depression. We can calculate the distance using a non-extendible nylon thread. Calculating it we get the distance of the thread as 9.5cm (approximately).

Since the scale of the map is 1 cm=1 km Hence the distance is 9.5km
