2. Question: What effect does the amount of water have on plant grow
Hypothesis:

Dependent variablel effect:
Hoi would I tort thir
Answer:
1. Hypothesis - If a plant doesn't have a good amount of light, then the plant will not grow.
Independent variable - The effect light has on plant growth
Dependent variable - How much your plant grows
How would I test this hypothesis? You will conduct a experiment with three different plants in three different areas with different amount of light, (in a window, outside in the dirt, inside in a closet) you will observe over two weeks how much each plant grows and record your results on a table.
2. Hypothesis - If the plant has too much water, then the plant will die
Independent variable - The effect water has on plants.
Dependent variable - How much growth will the plant go through with different amounts of water
How would I test this hypothesis? You will conduct a experiment with three different plants with three different amounts of water. One will have a quarter of a cup, two will have three quarters of a cup, three will have a whole cup of water. You will observe the growth over two weeks and record your results on a table.
Explanation:
Remember that a hypothesis is a educated guess based on what you will think will happen before performing a experiment. Also know that independent variables is what you are testing in a experiment and a dependent variable is what you're measuring in a experiment.

how does our water use affect the bay-delta ecosystem?
Answer:The Sacramento-San Joaquin Rivers Delta and San Francisco Bay (hereinafter “Bay-Delta”) is an important economic and environmental resource benefitting all of California and the nation. The Northern California Water Association (NCWA) and Sacramento Valley water resources managers recognize the importance to California’s future of a healthy Bay-Delta and providing high quality and reliable water supplies for all beneficial uses. For the past several decades, NCWA has been a strong and constructive participant in the various processes designed to help solve the challenges in the Bay-Delta. We will continue to play a constructive role in implementing necessary solutions to Bay-Delta problems, as long as the actions do not affect the ability to serve water for multiple beneficial uses in the Sacramento Valley, including cities and rural communities, fish, farms, birds and recreation.
NCWA and Sacramento Valley water resources managers have supported the state’s co-equal goals–providing a more reliable water supply for California and protecting, restoring and enhancing the Delta ecosystem–and have encouraged success in Voluntary Agreements as a new way forward in California.

A. Ticks draw blood from a deer and can travel from host to host.
B. Female seahorses lay eggs and the male seahorses carry the eggs.
C. Bumblebees eat the nectar
from flowers and then spread the flower pollen
D. Mountain goats evolved hooves that spread apart and have pointed edges in front so they can climb and live on steep cliffs
Answer:
C.
Explanation:
In the context of evolutionary biology, coevolution refers to the evolution of at least two species, which occurs in a mutually dependent manner. ... An example is the coevolution of flowering plants and associated pollinators (e.g., bees, birds, and other insect species)
Different types of cells can have certain organelles and structures in common. Which types of cells definitely contain cell walls?
SC.912 L 14.3
O plant and animal cells
0 plant and eukaryotic cells
o plant and prokaryotic cells
animal and eukaryotic cells
Answer:
plant and eukaryotic cells (B)
Explanation:
animal cells have a cell membrane but no cell wall and prokaryotic organisms lack a nucleus or any other membrane bound cell organelle.
Plant and prokaryotic cells definitely have a cell wall. So, the correct option is C.
What is Cell wall?Cell wall is defined as the structural layer that consists of polysaccharides and is present outside the plasma membrane which can be rigid, rigid and flexible. This provides protection to the cell from external factors that may be harmful to the cell and also provides structural support.
Plant and prokaryotic cells definitely have a cell wall. The cell wall of a prokaryotic cell is present under the capsule while the cell wall of a plant cell is a specialized form of extracellular matrix that surrounds each cell of a plant. This provides structural support to the cell and protects the cell against infection and mechanical stress
Therefore, the correct option is C.

the water in the solution moves into the plant cell.
the water in the solution moves out of the plant.
the solutes in the solution have a higher concentration than the solute concentration inside the plant cell.
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell.
the water is moving down its concentration gradient from high to low. the water is moving down its concentration gradient from low to high.
Answer:
The correct answer is -
the water in the solution moves into the plant cell
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell
the water is moving down its concentration gradient from high to low.
Explanation:
The hypotonic solution consists low concentration of solutes and a higher concentration of water as compared to the concentration of solutes and water of other solutions or cells. Water tends to move from a higher concentration of water to a lower concentration of water therefore the cell swell and then ultimately burst.
Water movement in such conditions is known as the movement down the concentration gradient as it moves from its higher concentration to a region of its lower concentration.

What is Clean water act?The Clean Water Act (CWA) establishes the fundamental framework for controlling the discharge of contaminants into American waters and for controlling surface water quality requirements.
The Federal Water Pollution Control Act, which served as the CWA's starting point, was passed in 1948; nevertheless, in 1972, it underwent a considerable organizational and growth. As the Act underwent modifications in 1972, "Clean Water Act" gained its widespread name.
The EPA has launched pollution control initiatives under the CWA, such as regulating industrial effluent. Moreover, the EPA has created national water quality guidelines and recommendations for contaminants in surface waterways.
