Answer:

Stoma represents the interface between the environment and the plant, helping to obtain the necessary CO2.

Explanation:

Stoma are groups of two or more specialized epidermal cells whose function is to regulate gas exchange and perspiration.

The frequency or density varies widely from a few tens to thousands per mm2, due to the influence of environmental factors, leaf morphology and genetic composition.

The following three resistors (Ohms) are in parallel with one voltage source. What is the total current running through circuit?

Zepler [3.9K]

Explanation:

The total resistance Rt is given by

1/Rt = 1/Ra + 1/Rb + 1/Rc = 1/5 + 1/4 + 1/7 = 0.593

or Rt = 1.69 ohms

The total current I running through the circuit is

I = V/Rt = 2.37 A

A remote-controlled boat traveled 18 feet heading west and 24 feet heading south, totaling 42 feet over the course of 10 seconds

Dominik [7]

Answer:

3 ft/s

Explanation:

given,

distance in west, d₁ = 18 ft

distance in south, d₂ = 24 ft

time taken to travel 42 ft = 10 s

speed of boat in north = x ft/s

Speed of the boat when heading west = (x - 3) ft/s

$Average\ speed = \dfrac{total\ distance}{total\ time}$

$v_{avg}= \dfrac{42}{10}$

$v_{avg}= 4.2\ ft/s$

again using the above formula

now, total time

t = t₁ + t₂

$10 = \dfrac{18}{x-3} + \dfrac{24}{x}$

on simplifying

10 x² -72 x + 72 = 0

On solving the above equation we get

x = 6 ft/s

Hence, speed of boat in west direction, 6 -3 = 3 ft/s

speed of boat in south direction = 6 ft/s
