Which has the most buffering capacity at pH -6?

Biology
1 answer:
kati45 [8]3 years ago
7 0

Answer:

D. A 1M solution of Alanine

Explanation:

Buffering capacity is the capacity of a solution or substance to change the Ph of another substance when added to it in 1, so the buffering capacity of all of them, since they have the same Ph, would depende solely on the amount of moles os the given substance that you will add, in this case the substance that has the most matter would be D. A 1M solution of Alanine, that option would have the most buffering capacity since it is a full mole of matter.

How does one determine the number of protons, neutrons, electrons in an atom
KengaRu [80]

Remember that the number of electrons are equal to the number of protons, and to find the number of protons you have to look and see the atomic mass of the atom is equal to the number of protons, and to find the number of neutrons you have too subtract the atomic mass to the atomic number.

Example:

You want to find out how many protons, neutrons, and electrons are in Platinum:

  • Atomic number is equal to the number of protons:
  • 78 = 78
  • So platinum has 78 protons and electrons.
  • Subtract atomic mass to atomic number:
  • 195 - 78 = 117 (forgetting about the decimals)

So platinum has "78 protons, and electrons, and has 117 neutrons."

Hope this helps!

Which of the following organelles assembles proteins? ribosomes Golgi apparatus nuclear envelope or endoplasmic reticulum
Artist 52 [7]

The right answer is Ribosomes

The ribosome is a complex composed of RNA and ribosomal proteins, associated with a membrane (in the granular endoplasmic reticulum) or free in the cytoplasm. Common to all cells (prokaryotes and eukaryotes), the ribosome (and especially its composition) varies according to the organisms, even if it is always composed of two distinct subunits.

The ribosome is a huge ribonucleoprotein complex that allows the translation of mRNAs into proteins.

Place the steps of endochondral ossification in order, starting with the creation of a cartilage model and ending with the prese
Ratling [72]

The correct  steps of endochondral ossification is:

  1. A periosteal bone collar develops.
  2. spongy bone and the medullary cavity form in the diaphysis.
  3. The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
  4. The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
  5. The spongy bone forms in epiphysis.

<h3>Which bones grow by endochondral ossification?</h3>

Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.

Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.

Staphylococcus epidermis appears _________, whereas escherichia coli appears _________ after the gram stain.
BigorU [14]

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.

Staphylococcus is a Gram-Positive Bacteria i.e. it takes up the Gram stain.

Escherichia coli or E. coli is a Gram-Negative Bacteria i.e. it does not take up the Gram stain.

Gram Staining is done by immersing the bacterial sample in a solution of dye and then observing it under microscope after proper rinsing.

Gram Positive Bacteria are those bacteria that show a positive outcome on staining. Gram Positive Bacteria appear Stained after staining.

Gram Negative Bacteria are those bacteria that show a negative outcome on staining. Gram Negative Bacteria does not take up the stain and appear stainless.

The epidermis of Staphylococcus which is a Gram-Positive Bacteria appears to take up the stain whereas Escherichia coli which is a Gram-Negative Bacteria does not take up the stain.

Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.
