Can someone help me identify what A, B, C, and D are in the watershed diagram?? need help asap!
sukhopar [10]

To identify the parts of the watershed in the diagram above, we have the following:

A- Stream channel

B- Tributary

C- Watershed boundary

D- Estuary

<h3>What is a watershed?</h3>

Watershed refers to an area having a runoff that occurs as a result of rainfall and such waters gather at a common point. In other words, watershed is known as an area that "sheds" water into a particular water body.

We can see that watershed has tributary, boundary, estuary (water body) and a stream channel.

An article is bought and sold with a profit of 25% of selling price,find the profit percent​
zvonat [6]

Answer:

<h3>33.3%</h3>

Explanation:

profit percent = Sp-Cp/Cp * 100%

Sp is the selling price

Cp is the cost price

Let the selling price of the article be x

If it is sold with a profit of 25% of selling price, then;

Profit = 0.25x

Since Profit = Sp - Cp

0.25x = x - Cp

Cp = x - 0.25x

Cp = 0.75x

Substitute into the formula

Profit percent = 0.25x/0.75x * 100

Profit percent = 0.25/0.75 * 100

Profit percent = 1/3 * 100

Profit percent = 33.3%

Hence the profit percent is 33.3%

Reachers to study the relationship between glucose concentration oxygen level one ATP production in one type of Emanual Sam sale
astraxan [27]

Answer:Objective: To determine the combined effect of oxygen level and glucose concentration on cell viability, ATP production, and matrix synthesis of temporomandibular joint (TMJ) disc cells.

Design: TMJ disc cells were isolated from pigs aged 6-8 months and cultured in a monolayer. Cell cultures were preconditioned for 48 h with 0, 1.5, 5, or 25 mM glucose DMEM under 1%, 5%, 10%, or 21% O2 level, respectively. The cell viability was measured using the WST-1 assay. ATP production was determined using the Luciferin-Luciferase assay. Collagen and proteoglycan synthesis were determined by measuring the incorporation of [2, 3-(3)H] proline and [(35)S] sulfate into the cells, respectively.

Results: TMJ disc cell viability significantly decreased (P < 0.0001) without glucose. With glucose present, decreased oxygen levels significantly increased viability (P < 0.0001), while a decrease in glucose concentration significantly decreased viability (P < 0.0001). With glucose present, decreasing oxygen levels significantly reduced ATP production (P < 0.0001) and matrix synthesis (P < 0.0001). A decreased glucose concentration significantly decreased collagen synthesis (P < 0.0001). The interaction between glucose and oxygen was significant in regards to cell viability (P < 0.0001), ATP production (P = 0.00015), and collagen (P = 0.0002) and proteoglycan synthesis (P < 0.0001).

Conclusions: Although both glucose and oxygen are important, glucose is the limiting nutrient for TMJ disc cell survival. At low oxygen levels, the production of ATP, collagen, and proteoglycan are severely inhibited. These results suggest that steeper nutrient gradients may exist in the TMJ disc and it may be vulnerable to pathological events that impede nutrient supply.
