1:5 dilution = 1/5 dilution = 1 part sample and 4 parts diluent in a total of 5 parts. If you need 10 ml, final volume, then you need 1/5 of 10 ml = 2 ml sample. To bring this 2 ml sample up to a total volume of 10 ml, you must add 10 ml - 2 ml = 8 ml diluent.

Difference between direct and indirect effect
Direct effects, as the name suggests, while not manipulated or communicated by a third party, deal with the direct influence of one entity on another. Indirect effects can be described as the influence, mediated or passed on by a third, of one organism or species on another.
Name 2 body systems that interact to maintain
homeostasis in the human body and explain how they do
Answer:
Internal Temperatures
Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin's surface.
OR,
The nervous and endocrine systems exert the ultimate control over homeostasis because they coordinate the functions of the body's systems. Regulation of body temperature, blood pressure, pH, and glucose concentration are four examples of how the body maintains homeostasis.

Describe the sodium potassium pump using as much detail as possible. Bonus if you can accurately describe how this relates to cystic fibrosis. and i will make u brainliest
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell

Why might a company decide against using hydroelectric Energy as an alternative energy source
A. Gathering it requires pulling from unclean sources
B. Gathering it creates noise pollution for surrounding areas
C. Gathering it releases carbon dioxide gases into the air
D. Gathering it can have a negative affect on natural habitats
The company's decision against using hydroelectric Energy as an alternative energy source might be Gathering it can have a negative affect on natural habitats.
Why is hydroelectric power not a good energy source?Hydropower can also cause environmental and social problems. Waterholes drastically change the landscape and rivers they are built on. Dams and reservoirs can decrease river flows, raise the water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.
Thus, the correct option is "D".

When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.
Answer:
If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

What important soil function does soil structure influence ?
Answer:
A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants will die!

An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure performs a similar function? A. cell membrane B. cytoplasm C. nucleus D. vacuole
Answer:
A. Cell membrane
Explanation:
The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.
The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.
Thus, the correct answer is option (A).

Explain how the electron transport chain makes ATP.
Answer:
t
Explanation:
While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.
Answer:
Explanation:
during electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix through ATP synthase, producing ATP
Which of the following is created from amino acids linking together?

Explanation:
The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.
