Three plants were grown to study the effects of nitrate and magnesium ion deficiency on their development. They were kept in the same conditions, except for the types of minerals supplied.
Use
Plant A was provided with all essential minerals.
Plant B was given all minerals except nitrate ions. Plant C was given all minerals except magnesium ions. State three conditions, other than water and the concentration of mineral ions, that would need to be kept the same for all the plants, in order to make the investigation a fair test
Answer:
Periods of light-timeTemperatureSubstrate/Soil typeExplanation:
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.

What do you think are the three biggest changes a household could make to reduce its use of water?
Answer:
turn water of when brushing teeth, take shorter showers and dont waste water
Explanation:
Compare and contrast passive transport, active transport, and osmosis
Answer:
Passive transport moves molecules and ions from a higher concentration to a lower concentration without any energy while active transport does the same thing only it uses energy. Osmosis deals with the net movement of solvent molecules through a membrane with a higher solute concentration. Osmosis and active transport both work together, while osmosis does its own movement the active transport moves the dissolved solutes across a membrane against a concentration gradient.
Active transport and passive transport are almost the same they function the same only one doesn't require energy while the other one does. Hence why active transport and osmosis work well together it's because of the energy that helps transport dissolved solutes.
Hope this helped :)

Plants that live in hot, dry climates have evolved mechanisms to help conserve limited water supplies. One example is the closing of leaf openings by guard cells during the day to decrease water loss from their leaves. This detection of and response to an environmental stimulus is an example of
Answer:
feedback mechanism
Explanation:
Feedback mechanism: In biology, the term "feedback mechanism" is described as a physiological loop that is responsible for bringing up the body either away or towards the steady or normal state. The feedback mechanism is also denoted as "feedback loop" and is responsible for either inhibiting or amplifying a specific biological pathway. Therefore, these pathways tend to return the body towards "homeostasis".
In the question above, the given statement is an example of a "feedback mechanism".

Which of these would provide the best evidence for the theory of evolution?
A
fossils of ancient tigers that had larger ears than tigers have today
B
oil found deep under the ice sheets of Antarctica
C
a person’s hair growing faster in the summer than it does in winter
D
ancient maps that show that countries had different borders long ago
Answer:A
Explanation:
The meaning of evolution-the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
So, B is incorrect since it is talking of the present. C, shows the growing of hair, but has no answer to evolution, since it does not show an organism growing from the past to present. D, shows evolution of land but no “living organism”
In conclusion, the best answer is A.

Resources.

Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.

I believe your answer is C.
A student uses a microscope to observe cells in the root tissue of an onion. He
concludes that the cells are reproducing by mitosis.
Which hypothesis is supported by his conclusion?
a. The root tissue cells all have the same set of chromosomes.
b. The root tissue cells each have a unique genetic make-up.
c. The root tissue cells produce identical gametes..
d. The root tissue cells split to form stem cells.
The correct answer is option a. The root tissue cells all have the same set of chromosomes as it clearly explains the hypothesis.
Onions (Allium cepa L.) have eight relatively large chromosomal pairs (2n = 16) that can easily detect CA.
Mitosis creates two identical daughter cells, each containing the same number of chromosomes as the parent cell. In contrast, meiosis produces four unique daughter cells, each with half the number of chromosomes in the parent cell. Therefore, during the mitotic cell cycle, the DNA content per chromosome doubles in the S phase (each chromosome begins as a chromatid and becomes a pair of identical sisters in the S phase). However, the number of chromosomes remains the same.
How many chromosomes do cells have after the G1, S, and M phases?Onion root cells have chromosome 16 in each cell after the G1, S, and M phases.
Thus it concluded that mitosis causes root tissue cells to all to have the same set of chromosomes.

Explanation:
The process of osmosis is best illustrated by the movement of a. water into root hair cells b. oxygen intro red blood cells c. carbon dioxide through stomates d. glucose through phloem
Answer:
a. water into root hair cells
Explanation:
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a semi-permeable from a region of high concentration to a region of lower concentration.
Hence, the process of osmosis is best illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.
what could cause a population to reach it's carrying capacity
Answer:
As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).
