Which organisms can be treated with penicillin g (benzylpenicillin)? (select all that apply.)?

1 answer:

6 0

The question does not give any options, I found the excercise on the web and here are the options:
a. Methicillin-resistant Staphylococcus au-reus
b. Neisseria meningitidis
c. Pseudomonas aeruginosa
d. Streptococcus pyogenes
e. Treponema pallidum

The correct choices are: B, D, E

Penicillin G is the primary medication of choice for N. meningitidis. It is a medication of first choice for contaminations caused by sensitive gram-positive cocci, including S. pyogenes. It is a medication of choice for T. pallidum. It isn't powerful against methicillin-resistant S. aureus or P. aeruginosa.

An individual's complete collection of genes is called his or her:

BabaBlast [244]

The right answer is genotype.

The genotype is the information carried by the genome of an organism, contained in each cell in the form of deoxyribonucleic acid DNA. Carried by the chromosomes, it is located inside the nucleus in eukaryotes and in cytoplasm in prokaryotes.

In humans, it is estimated that the number of genes is between 25,000 and 30,000.

The net energy yield from this pathway, where glucose is broken down through several steps forming pyruvate, is ________ molecul

stepan [7]

Answer:

2 molecules of ATP and 2 molecules of NADH

Explanation:

Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.

Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.

In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase

All the DHAP molecules get converted to G-3-P in order to enter the next phase.

In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.

Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.

What is the purpose of cells?

Nezavi [6.7K]

Explanation:

Hey there!

The main function of cell is to make a life possible in the universe by performing various type of vital activities.
Various type of cell performes various type of activities. The same type of cell combine together to form tissue. Similarly, similar tissue combine and form organ. Now, Organs combinly form form a system and all system form a whole body. They combinly perform task for sustaining life in the universe.
Cancer are caused mainly due to abnormal growth of cells. It shows various type of symptoms. Such as;

The wounds donot heal faster, instead it may be worse.
Unwanted bleeding may occur from nose, mouth, or other parts.
You may see lump in some parts of body.(Thickness of skin).
They also may have problem of hair loss in more amount.

Explain how the ages of the rocks on the ocean floor support the theory of seafloor spreading

Dafna11 [192]

The Drilling sample of the Seafloor spreading theory helped in determining rock ages on the floor of ocean.

Explanation:

The formation of crusts of ocean by the process of volcanic eruptions in the ridges of the middle ocean is the theory of seafloor spreading proposed by Hammond Hess. The movement of tectonic plates continuously forms sea floors through spreading of seafloor. The several evidences in support of this theory has been seen, of which some are – molten material eruptions, magnetic stripes in rocks and rock ages.

The drilling evidence is the final one that was proved by taking samples of rock by drilling in ocean and by bringing them with pipes. The observation of these rocks proved that older rocks were collected from farther ridges and youngers are found in the central ridges.
