How do I write a hypothesis in "If...then..." format?
Research question: "What vegetation type supports the highest abundance of life"
My answer is the savannah/woodland
Answer:
If I were you, I would make my hypothesis something like:
"If the vegetation type is a savannah/woodland, then it will support the highest abundance of life."
Explanation:
I know that hypothesis can be tricky to write at first, but if you turn the research question into a sentence, then you can write your hypothesis. Best of luck with your experiment.

how does renewable energy affect non-human organisms? (plants, animals, bacteria, fungi,etc.)
Answer:
Non Renewable Energy Impact on Environment
All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

What cellular process is occurring in the organelle labeled A?
(5 Points)
Students constructed a diagram to represent two related cellular processes.
F. Photosynthesis
G. Cellular respiration
H. DNA replication
J. Protein synthesis
Answer:
F. Photosynthesis
Explanation:
The organelle pictured (a chloroplast) seems to be absorbing energy from the sunlight and that is included in the process of photosynthesis.
The carbohydrates (glucose) are formed by the process of photosynthesis in the chloroplast of the cell which then sent to the mitochondria for the production of ATP through glycolysis. Thus, the correct option is F.
What is Photosynthesis?
Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (glucose). This process takes place in the chloroplast of plant cell where chlorophyll is present, this pigment (chlorophyll) is responsible for trapping the sunlight which is responsible for conduction of photosynthesis.
The products of photosynthesis (glucose) is sent to the mitochondria of cell for the production of ATP by the process of glycolysis. This ATP is then utilized by the cell in other cellular mechanisms.
Therefore, the correct option is F.

How does water polarity affect the way water interacts with different substances?
Answer:
Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules. ... Because of its polarity, water can form electrostatic interactions (charge-based attractions) with other polar molecules and ions.
Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. About two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?
Answer:
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling

The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?
Answer:
Time, t = 9.62 secs.
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex] ....equation 1
Making time the subject formula;
[tex]Time = \frac{distance}{speed}[/tex] .....equation 2
Given the following data;
Distance = 100m
Speed = 10.4m/s
Substituting into equation 2;
[tex]Time = \frac{100}{10.4}[/tex]
Time, t = 9.62 secs.

what happens to energy during cellular respiration
Answer:
During cellular respiration glucose and oxygen are converted into carbon dioxide and water and the energy is transferred to ATP.
Explanation:
What will happen if ATP and NADPH are already used up at night?
Answer:
If ATP and NADPH are already used up at night , the production of glucose will stop.
Explanation:
IMPORTANCE OF ATP AND NADPH -: To temporarily store energy, the light-dependent reactions generate ATP and either NADPH or NADH. In light-independent reactions, these energy carriers are used to drive the energetically unfavorable mechanism of "fixing" organically inorganic CO2.
ATP is the molecular energy "currency" in biological systems. All energy produced by living organisms' cellular respiration must end up being used as ATP to power it. NADPH is a hydrogen carrier molecule reduced by NADP (Nicotinamide Adenine Dinucleotide Phosphate). While the light-dependent reactions take place, energized electrons hop on to electron carriers excited by photon energy from the sun (On Photosystem 2) and finally get to Photosystem one.
If ATP and NADPH are already used up at night, the fixation of carbon dioxide into glucose will halt. In other words, the light-independent reaction of photosynthesis will stop.
There are essentially 2 reactions in photosynthesis:
light-dependent reactionlight-independent reactionIn the light-dependent reaction, radiant energy is used to excite electrons chlorophyll molecules while electrons in water replace the excited electrons. ATP and NADPH are generated in the process.
The ATP and NADPH produced during the light-dependent reaction of photosynthesis are essential for the reduction of carbon dioxide into glucose in the light-independent reaction.
Hence, unless the light-dependent reaction takes place to make ATP and NADPH available, there is no other way to produce the precursors for the fixation of carbon dioxide into glucose.

Which sphere in the Earth system is also part of the hydrosphere? O A. Atmosphere O B. Biosphere O C. Geosphere D. Cryosphere
A. atmosphere
explanation: there is water vapor in the atmosphere that is considered to be part of the hydrosphere.
In an ecosystem, atmosphere is a sphere in the Earth system which is also part of the hydrosphere.
What is an ecosystem?
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

how does water potential affect molarity or how is molarity and water potential related
Answer:
If the solute concentration of a solution increases, the potential for the water in that solution to undergo osmosis decreases. Therefore, the more solute that is added to a solution, the more negative its osmotic (solute) potential gets.
