[Done] Why does photosynthesis require water? A. Because water provides oxygen atoms B. Because water provides electrons C. Because water accepts electrons D. Because water acts as a catalyst

[Done] What statement is not true about photosynthesis? Select one: A. ATP and NADH are produced during the light-dependent reactions. B. Carbon dioxide is an input in the light-dependent reactions. C. Oxygen is a limiting factor in the rate of photosynthesis. D. The sun's energy is harnessed and converted into chemical energy.

[Done] Why is it a bad idea from an ecological and commercial standpoint for a company to fill a saltwater marsh with dirt and cement to create more land for oceanfront housing near an estuary?

[Done] Compared to the cnidaria, platyhelminthes has a ______. Select one: A. more complex nervous system B. more complex coelom C. less complex nervous system D. less complex coelom

[Done] The United States consumes 2.6 billion cases of bottled water per year. Assume that each case holds 24 half-liter bottles. Each case is 10.2 inches tall, 15.1 inches long, and 8.3 inches wide. 1. If all of these cases were lined up end-to-end at the equator, how many times would they go around the Earth? - Note: The circumference of the Earth's equator is 24,901 miles. 1 mile = 5280 feet. 2. What would be the perimeter and area of the base of all of these cases together? 3. What would be the total volume of all these cases?

[Done] A scientist finds a new life form and determines that it contains no nuclei. Which of the 6 kingdoms could it belong to? Select the list that contains all the possible kingdoms. A. Protista and Plantae B. Eubacteria and Archaebacteria C. Eubacteria, Archaebacteria, and Plantae D. Eubacteria, Archaebacteria, and Fungi

[Done] Which organelles are found in both plant and animal cells? A. Ribosomes and mitochondria B. A nucleoid and cell membrane C. Cell wall and genetic material D. A nucleus and a cell wall

[Done] Write an equation in slope-intercept form for each table below. Show how you found the slope and y-intercept. Table (1): | x | 0 | 1 | 2 | 3 | 4 | |---|---|---|---|---|---| | y | 0 | 2.5 | 5 | 7.5 | 10 | Steps to find the slope (m) and y-intercept (b): 1. Calculate the slope (m) using two points from the table: \( m = \frac{y_2 - y_1}{x_2 - x_1} \) Let's use the points (0, 0) and (1, 2.5): \( m = \frac{2.5 - 0}{1 - 0} = 2.5 \) 2. Determine the y-intercept (b) by identifying the y-value when x = 0: The y-intercept is 0. Equation in slope-intercept form: \[ y = 2.5x + 0 \] Or simply: \[ y = 2.5x \]

[Done] What is the y-intercept of the equation \( y = 11(9^x) + 3 \), if any?
