what is the pH of a solution with a H+ ion concentration of 1 x 10^-4

Answers

Answer 1

Answer:

A logarithmic scale condenses the range of acidity to numbers that are easy to use. Consider a solution with [H + ] = 1.0 × 10 -4 M. That is a hydrogen-ion concentration that is 1000 times higher than the concentration in pure water. The pH of such a solution is 4.00, a difference of just 3 pH units.

All living things need matter and energy to survive. Organisms get matter and energy from food.

Describe how organisms use matter and energy.

Answers

Animals drink and eat food to obtain the matter and energy they need for their life processes. Some organisms, such as plants, can make their own food. An organism that makes its own food is called a producer. Plants are able to use the energy from sunlight to produce sugars, which are a source of energy and matter.

Answer:

Explanation:

Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).

The reaction of an exploding firework occurs at a faster rate than a burning candle.

The activation energy required for an exploding firework is less than the activation energy required for a burning candle.

Answers

Answer:

In the explanation-----

Explanation:

The first statement is correct since the gun explosive powder explodes since they light a fuse at first, and once the fuse reaches the end it explodes as a reaction. However, for a candle it relies on the lit fire. Wax is a tough and a longer substance to melt compared to a exploding firework.

For the activation energy for the firework, it uses that energy in a result of the fuse reaching the end and reacting with the gun powder.

The diagram below represents part of a process that occurs in cells. Which process is represented?

Answers

The process in cells represented by the diagram would be translation or protein synthesis.

The translation is a process in cell biology during which the genetic codes in messenger RNA are decoded into their respective amino acids and linked together by peptide bonds. The process usually takes place in the ribosome of eukaryotic cells.

During translation, the genetic codes on mRNA are read and the amino acid corresponding to each code is released. The small ribosomal unit first binds to the mRNA at the beginning. Thereafter, the tRNA binds to the start codon on the mRNA before the binding of the large ribosomal subunit to complete the initiation complex.

The plasma membrane is a thin flexible boundary between a cell and its enviorment.All cells have a plasma membrane. How does a plasma membrane maintain homeostasis within a cell

Answers

Answer:

The plasma membrane maintains homeostasis in the cell by keeping cell contents in and foreign material out, and by providing controlled routes for the transportation of fuel, fluids and waste.

The plasma membrane is very important because it allows a cell to maintain homeostasis by:

Controlling the flow of foreign substances into the cellControlling the movement of materials out of the cell Transporting materials within the cell

Homeostasis refers to the inner environment of the cell being maintained such that it can carry out its duties.

The plasma membrane helps with that by first controlling what materials come into the cell to ensure that the inner environment isn't disrupted. It also limits those going out for the same reason.

Substances need to move around in the cell and the membrane handles this as well to ensure that substances get to the part of the cell where they help with maintaining the cell.

In conclusion, the plasma membrane is hugely important to the cell as it maintains homeostasis.

In a woodland ecosystem, the number of species of microorganisms in the soil that do not
harm plants increases. How does this rise in biodiversity affect the sustainability of the
ecosystem?
A The rise in biodiversity makes the ecosystem less sustainable.
B The rise in biodiversity makes the ecosystem more sustainable.
C The rise in biodiversity does not change the sustainability of the ecosystem.
D The rise in biodiversity makes the ecosystem only temporarily less sustainable.

Answers

Answer:

I think it’s B

Explanation:

Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.

What is the rise in biodiversity in woodland ecosystem?

In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.

Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.

Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.

Therefore, The rise in biodiversity makes the ecosystem more sustainable.
