Psychology is a science because it follows the empirical method. ... We can directly observe and carefully measure externals such as what a person does, says, and marks down on a psychological test. We cannot directly observe a person's mind (e.g., internal thoughts, emotions).
How does penicillin kill bacteria? Penicillin augments the body's natural ability to enzymatically degrade bacterial peptidoglycan, causing the cells to lyse Penicillin targets a cross-linking reaction in cell wall manufacture. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan. Penicillin targets muramic acid in the cell wall. By damaging a key component of the cross-linking reaction, the cell can't build a strong peptidoglycan mesh and quickly breaks apart. Penicillin damages the lipid membrane of bacterial cells by enzymatically removing peptidoglycan from the membrane's outer surface. The weakened cells quickly lyse.
Answer:
The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.
Explanation:
Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.
These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.
Explain the cause of circulatory in frog
Answer:
In the frog, Rana, venous blood is driven into the right atrium of the heart by contraction of the sinus venosus, and it flows into the left atrium from the lungs. A wave of contraction then spreads over the whole atrium and drives blood into the ventricle, where blood from the two sources tends to remain separate.

Ahmad is using technic cross-pollination for his mango plants in his orchard. He said combines genetic materials from two parent plants of the same species will has many advantages. Justify the statement.
Answer:
Due to some extra features.
Explanation:
Genetic materials from two parent plants of the same species has many advantages because the offspring produced from two parents having characteristics from both parents which make it different from their parents. Due to this non-identical nature of offspring which has many new features which enables the plant to resist many diseases, faster growth and high productivity so that's why sexual reproduction has many benefits to organism.

why is climate change a serious threat to the least developed countries practicing agriculture as their main occupation mountain region island and low lying countries
Answer:
Increase in sea level on the low lying countries which leads to degradation and salinification thereby making the soil non-arable. Meanwhile on the mountain regions, melting glaciers caused by rain falling on snow leads to mountain floods, avalanches and extreme rockslide and thereby disrupting agricultural produce and wildlife.

The question is kind of confusing but from what I understand; missense mutations happen when an amino acid is changed to another amino acid. To find out more specifically, look at a codon chart trust me it helps so much lol (just search codon chart and go to images). missense mutations can also cause a premature stop codon so look for a changed amino acid and a stop codon when u look at the codon chart. maybe if u see the different pairs you can get a more specific answer. I hope this helps :)
Normally, this region is imprinted in the sperm, but not the egg. This means that the DNA on the ____________ copy of the chromosome will be methylated at the imprinting center, while the DNA on the ____________copy of the chromosome will not be methylated in this region.
Answer: The DNA on the paternal copy of the chromosome will be methylated at the imprinting center, while the DNA on the maternal copy of the chromosome will not be methylated in this region.
Explanation:
Chromosomes are DNA structures associated with proteins such as histones. They are found in the nucleus of cells and contain genetic information for the development and functioning of an organism. Human beings are diploid, meaning that they possess two copies of each of the 23 chromosomes (a total of 46).
Gametes, which are sex cells such as the sperm (produced by the male) and the egg (produced by the female) that are haploid. This means that they possess only one chromosome of each pair. During fertilization, a male gamete fuses with a female gamete to generate a zygote, which will give rise to a new human being. This new individual will possess half of the genetic material from its father and half from its mother. Thus having a total of 46 chromosomes, 23 from each parent.
Genetic imprinting modulates gene expression by chemical modification of DNA and/or modification of chromatin structure. Often, genetic imprinting causes a gene to be expressed only on the chromosome inherited from one of the parents. One example of imprinting is DNA methylation, which is a process by which methyl groups are added to DNA. Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed, that is, it will not produce a protein encoded by that gene. So, if a region of DNA is imprinted in the sperm cell, the paternal chromosome inherited from this sperm will be methylated in the genes of the offspring. And the offspring will only express the maternal copy inherited, which will not be methylated.
An inflatable balloon with the volume of 0.75 L at 303 K was placed inside the freezer where the temperature is 263 K. Find out what will happen to the volume of the balloon if the pressure remains constant.
Answer:
Final volume, V2 = 0.66 Litres
Explanation:
Given the following data;
Initial volume = 0.75 L
Initial temperature = 303 K
Final temperature = 263 K
To find out what will happen to the volume of the balloon if the pressure remains constant, we would use Charles' law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles' law is given by the formula;
[tex] VT = K[/tex]
[tex] \frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]
Where;
V1 and V2 represents the initial and final volumes respectively.T1 and T2 represents the initial and final temperatures respectively.Making V2 as the subject formula, we have;
[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]
[tex] V_{2}= \frac{0.75}{303} * 263 [/tex]
[tex] V_{2}= 0.0025 * 263 [/tex]
Final volume, V2 = 0.6575 ≈ 0.66 Litres

How does wet heat sterilization, such as an autoclave, work to inactivate bacteria and other infectious pathogens?
Answer and Explanation:
The microorganisms such as bacteria and fungi are basically composed of biological macromolecules (lipids, proteins, polysaccharides). As the temperature increases, the structure of proteins is disrupted and they lose their function. For example, enzymes that catalyze biological reactions are inactivated.
Therefore, wet heat sterilization is a process in which the material is heated during a certain time at a certain high temperature to destroy the microorganisms by producing the denaturation of structural proteins and enzymes.
