which structure can perform all the activities required for life?
A) DNA molecules
B) cells
C) organelles
D) nuclei

Answers

Answer 1

All the tasks necessary for life can be carried out by nuclei.

The "command center" of the cell is the nucleus, a large organelle that contains the DNA of the cell (deoxyribonucleic acid). The nucleus uses the genetic data in the DNA to control all cellular processes, including growth and metabolism.

The nucleolus, a more compact part of the nucleus, contains the RNA (ribonucleic acid). The instructions from the DNA are passed on to the rest of the cell with the help of RNA, which serves as a template for protein synthesis.

An organelle is a subcellular structure that, similar to an organ in the body, performs one or more particular functions for the cell. Some of the more important cell organelles include the ribosomes, which assemble proteins, the mitochondria, which provide chemical energy, and the nucleus, which stores genetic material.

what type of testing can be done in the clinical lab to determine which antimicrobial agents will most likely be effective at targeting a particular strain of organisms?

Answers

Antibiotic susceptibility testing can be done in the clinical lab to determine which antimicrobial agents will most likely be effective at targeting a particular strain of organisms.

Antimicrobials that will stop the growth of the bacteria or fungus causing a particular ailment are identified using a process called susceptibility testing. The outcome of this test will assist a medical professional in identifying the medications most likely to be successful in treating a patient's infection.

A culture of a suspected infection site, such as a wound, urine, or blood, is typically requested concurrently with a susceptibility test. The test, however, is typically only run when the culture is positive for one or more pathogens. In order to evaluate which antimicrobial medicine would be more successful in treating the infection and to assess whether the organism has developed resistance, the test may also be ordered when an infection fails to respond to therapy.

Why is DNA replication said to be semi-conservative?

Answers

DNA replication is said to be semi-conservative because of the process of replication, where the resulting double helix is composed of both an old strand and a new strand. Each strand of the double helix DNA would serve as a template for synthesis of a new strand. DNA replication process occurs during the Synthesis (S) phase of the eukaryotic cell cycle. As each DNA strand has the same genetic information, both strands of the double helix can serve as templates for the reproduction of a complementary new strand. The two resulting double helices, which each contain one "old" strand and one "new" strand of DNA, are identical to the initial double helix.

a protein called met18 has a pi of 5.65. in a buffer at ph 5 will it be positively charged,negatively charged, or neutral? what about at ph 7.5?

Answers

Met18 will carry a net positive charge if below pH 5.65 (at pH 5) and Met18 will carry a negative charge if above (at pH 7.5).

pl (isoelectric point) is the pH state when amino acids do not carry an electric charge or are neutral. The pI value is also defined as the pH value when amino acids do not migrate under an electric field.

The isoelectric pH (pI) of amino acids can be determined using the following principle. The pI is calculated as the average of the pKa values ​​of the group that gives the amino acid a +1 charge and the pKa of the group that causes the amino acid to have a charge of 0.

Solution pH < pKa (acid pH environment)

Amino acids will accept H+ (understand protonation).The amino acid group that can accept a proton will have a +1 charge

Solution pH > pKa (alkaline pH environment)

Amino acids will release H+ (deprotonate).Groups of amino acids that can release a proton will be charged -1

b. describe the three main ways in which epithelia carry out this barrier function, giving details of the mechanisms employed.

Answers

The three main ways in which epithelia carry out this barrier function are: Mechanical barriers, Chemical barriers, and Microbial barriers.

1) Mechanical (physical) barriers:

Tight connections between epithelial cells prevent infections from passing between the cells and entering the underlying tissues. Furthermore, air and fluid pass over epithelial surfaces, oxygenating and flushing the surface and reducing anaerobic bacterial growth and temporary adherence.

2) Chemical barriers:

The epithelium generates a number of chemical compounds that interfere with microbe adhesion and multiplication. The skin releases a number of chemical compounds that inhibit microbe adhesion to epithelium and multiplication.

The skin's sebaceous glands generate fatty acids, which contribute to an acidic environment that inhibits the development of many germs. Lysozyme, an enzyme that inhibits bacterial cell wall production, is released in tears, saliva, and perspiration. Antimicrobial peptides are released by all protective epithelial cells.

3) Microbiological barriers: 

Many epithelial surfaces are colonized by a flora of non-pathogenic commensal bacteria, which acts as an additional barrier against infection.

These microorganisms compete with pathogenic germs for space and resources, and they occasionally create antimicrobial proteins that further hinder epithelial adhesion.

Fst values are the measure of genetic variation. Allele frequencies of a population can shift over generations due to genetic drift, a process of evolution (sampling error).

Although genetic drift affects populations of all sizes, its impacts are most pronounced in small populations. Some alleles, including advantageous ones, may be lost as a result of genetic drift, while others may be fixed, or increase in frequency. A change in the frequency of alleles (gene variants) in a population through time is referred to as evolution in population genetics.

which membrane potential opens a sufficient number of the voltage-gated na n a channels to cause a significant change in the membrane potential (making it much less negative).

Answers

The membrane potential that opens a sufficient number of voltage-gated Na+ channels to cause a significant change in the membrane potential (making it much less negative) is called the action potential threshold.

The action potential threshold is the minimum depolarization of the membrane potential required to activate voltage-gated Na+ channels and initiate an action potential. When the membrane potential reaches the action potential threshold, a sufficient number of Na+ channels open, allowing Na+ ions to flow into the cell and further depolarizing the membrane. This depolarization causes even more voltage-gated Na+ channels to open, leading to a rapid and brief positive spike in the membrane potential known as the action potential. This rapid and self-propagating change in the membrane potential allows for the rapid transmission of signals along the axon of a neuron, and the initiation of a nerve impulse.
