a) My hypothesis is in this case is that the environmental conditions in the yard were too extreme which resulted in half of the trees dying.
b) I can test this hypothesis by asking myself, what environmental conditions were the trees in that caused half of them to die? I could read about different biomes and their climates and learn how well they support organic life such as grass, plants, crops, and even trees. I can then determine that half of the trees did not survive due to the extreme environmental conditions they were in.
Hope this helps!

The LED light source does not get hot. Explain why it is important that the pondweed remains at a constant
temperature?
The LED light source does not get hot because
Temperature affects rate of photosynthesis or rate of bubble production.Reaction or photosynthesis is controlled by enzymes.What is the LED explain?LED stands for Light Emitting Diode. LED lights produce light up to 90% more efficiently than incandescent bulbs. An electric current is passed through the microchip, which illuminates small light sources that we call LEDs, resulting in visible light. Compared to conventional light sources, which first convert electrical energy into heat and then into light, LEDs (light-emitting diodes) convert electrical energy directly into light, producing efficient light with little wasted electricity.

how is carbon dioxide produced in cells removed from our body?
Answer:
In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.
The main function of the circulatory system is to: Secrete (release) enzymesProduce hormones (testosterone/estrogen)Digest (break down) proteinsTransporting (moving) materials
To answer this question we need to look at each statement:
Secrete (release) enzymes: in this case is more propper of the digestive system since its function is to break food into usable nutrientes by the cells in the body.
Produce hormones (testosterone/estrogen): This is actually part of the endocrine system, that is in charge to produce and regulating hormone production.
Digest (break down) proteins: This is also part of the digestive system, as it was mentioned before their function is to break food into nutrients.
Transporting (moving) materials: This is correct, the circulatory system has the function to transport materials in and out of cells.

Use your understanding of free hydrogen and hydroxide ions in solution to explain why distilled water (pure H2O) would have a “neutral” pH (or a pH of 7.0)
Answer:
With all of this in mind, then, it would make sense if distilled water had a neutral pH of 7. The distillation process removes nearly all of its ionic, mineral and organic impurities, making it one of the purest forms of water available.
Botanical keys use (blank) contrasting statements which you must choose the most correct one. Enter a numerical answer.
Answer:
The keys are taxonomic literature based on the contrasting characters generally a pair called couplet.
The concentration of solutions is measured in a unit called moles (M). Now that you know this, use the picture to answer questions #1 - #5. The picture shows a red blood cell floating in a solution in a beaker. The picture also shows the concentrations of salt inside the red blood cell and the concentration of salt in the beaker.
Red blood cells (RBCs) would have a larger solute content outside of them than inside of them if they were detected in a concentrated salt solution.
Osmosis would cause the water to leak out of the cell, causing it to shrivel and stop functioning.
What occurs to red blood cells when they are exposed to a hypertonic solution?A red blood cell will swell up in a hypotonic solution and maybe rupture, but in a hypertonic solution it would shrink, making the cytoplasm thick and its contents concentrated, and may even perish.
Active transport involves the movement of chemicals from a low-concentration location to a high-concentration area in opposition to the concentration gradient. Being "active" means that this process uses energy (usually in the form of ATP).
Due to the diffusion mechanism, which asserts that water flows from a high concentration of water (RBC) to a low concentration of water when a cell is immersed in a concentrated solution (saline water).

When one phosphate group is removed by rupturing a phosphoanhydride bond during the process known as hydrolysis, energy is released and ATP is transformed into adenosine diphosphate.
When ATP degrades, which phosphate is released?Adenosine diphosphate (ADP), a version of the nucleotide with only two phosphates, is created when the outermost phosphate of ATP is removed to give energy. By adding a phosphate group to another molecule, ATP can change another molecule to power biological processes (a process called phosphorylation).
How does ATP release energy that living cells can utilize?The ATP molecule splits off one of its three phosphates when a cell has to expend energy to complete a task, resulting in the formation of ADP (Adenosine di-phosphate) + phosphate. It is now possible for the cell to use the energy that was previously bound to that phosphate molecule to carry out its operations.

Four steps of Cellular Respiration
Glycolysis. During glycolysis, the six-carbon sugar glucose is going thru some of chemical changes. In the end, it's miles converted into molecules of pyruvate, an natural molecule with 3 carbons.Oxidation of pyruvate. The mitochondrial matrix, the inner most compartment of the mitochondria, gets every pyruvate produced for the duration of glycolysis.Cycle of citric acid. A four-carbon molecule and the created acetyl CoA engage and go through a chain of events, in the end renewing the preliminary four-carbon molecule.Phosphorylation through oxidation A gradient is created as protons are pumped out of the matrix as electrons flow down the chain, liberating power as they do so. Through the introduction of ATP through the enzyme ATP synthase, protons float returned into the matrix.Chemical Energy: C6H12O6 6O2 → 6CO2 6H2O (in ATP)According to the equation, oxygen (O2) and glucose (C6H12O6) react to provide carbon dioxide (CO2) and water (H2O), which releases power.

The history of life as recorded by fossils, which are the remains or imprints of species from past geological eras preserved in sedimentary rock, is known as the fossil record. Continents that were once together must have been together in the geological past, according to fossils of the same genus or species. The dead and organic remains of extinct species that were buried deep in the earth millions of years ago are known as fossils. It is defined in a more straightforward manner as the remains or evidence of plants and animals that once lived in the past.
When an organism or fossil demonstrates a process of steady change over time, it is said to have undergone an evolution. Extinction, on the other hand, is the event in which species vanish from the ecosystem as a result of any method, such as habitat destruction.

how are speciation and niches interconnected concepts?
Specification and niches are related ideas:
The process by which populations divide into distinct species is known as speciation. Cladogenesis describes the division of lineages as opposed to anagenesis, or phyletic evolution within lineages. Biologist Orator F. Cook used it for the first time in 1906.
A species' niche is its role within the ecosystem. In other terms, an organism's "niche" is how it "earns a living." A niche will include an organism's role in the movement of energy across the ecosystem.
Closely related species (such as sister taxa) frequently occupy incredibly diverse ecological niches and may have noticeably different geographic ranges despite sharing a shared evolutionary history.
The concept of "budding speciation" is one method that could help to explain how disparities in niche and dispersion features might swiftly evolve. "Budding speciation" is the process through which new species appear as initially small, colonizing colonies that reach reproductive isolation. This theory of species origin predicts that distributions of sister species should be noticeably lopsided at the time of speciation.
