Function of the rod cellsResponsible for vision at low light levels

Biology
2 answers:
Darina [25.2K]2 years ago
5 0

Answer:

Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.

Answer:

There are 3 types of cones which we will refer to as the short-wavelength sensitive cones, the middle-wavelength sensitive cones and the long-wavelength sensitive cones or S-cone, M-cones, and L-cones for short.

The light levels where both are operational are called mesopic.

Researchers are studying the abnormal activity of kinases in relation to cancer. Theoretically, how might researchers use signal
myrzilka [38]

Answer:

I am pretty sure that the answer is A.

Explanation:

Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.

I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or  growth factors (not in the answer choices). Since one of the factors that  leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!

If you see a cell with blue fills of varying lengths representing the values, the cells most likely have ________ applied to the
ioda

When a person  see a cell with blue fills of varying lengths representing the values, the cells most likely have data bars applied to them.

<h3>What are Data bars?</h3>

Data bars are known to be a kind of  conditional formatting that alters based on the data that is said to been shown.

The bigger the number, the fact still remains that the  longer the bar that appears in a cell. They often do look like an advanced feature but they are said to be easier to input the data bars to a spreadsheet in Excel using few clicks.
