Choose the term that best matches the description given. Treatments that destroy or decrease the growth of a microbe infection in a patient ______ a. Disinfects b. Antiseptics c. Sterilization d. Antimicrobials e. Quarantine
Answer: The correct option is D (Antimicrobials).
Explanation:
Antimicrobial treatment is defined as therapies that are given to patients to either inhibit or kill the growth of microorganisms IN their body cells. The antimicrobial treatment can be grouped into two based on their mechanism of action. These includes:
--> Microbiocidal therapy: This type of treatment when given, kills the microorganisms in the cells of the patient.
--> Microbiostatic therapy: This type of treatment aims at inhibiting the growth of microorganisms when administered to a patient.
The antimicrobial drugs achieve their role usually through their different modes of action which includes:
--> cell wall inhibition
--> inhibition of cell membrane function
--> protein and nucleic acid synthesis inhibition.
Disinfects, antiseptic and sterilisation are all different ways of eliminating microorganisms but not used as invitro (within) treatment for patients. Therefore the term that best matches the description given is antimicrobials.

[50 points... Will give brainliest] Explain how natural selection is impacted by genetic differences, variation, and survival.
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Which of the following would lead to a lower rate of photosynthesis?
A
decrease in CO2
B
decrease in O2
C
increase in CO2
D
increase in O2
Answer:
A. Decrease in CO2
Explanation:
This is due to the fact that in photosynthesis plants use carbon dioxide, water and sunlight to make sugar and oxygen. So Oxygen would have no impact on the rate photosynthesis occurs. And a increase in CO2 would increase its rate. Only when there is a lack of CO2 will the plant rate be impacted

An Olympic sprinter has just broken the world record for the 100-meter dash. Which process will her body likely use to recover from her “oxygen debt”?
Answer:
Anaerobic respiration
Explanation:
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
The process through which the Olympic sprinter's body will likely use to recover from her “oxygen debt” is: an anaerobic respiration.
Anaerobic respiration can be defined as a chemical and biological process that involves the use of electron acceptor rather than oxygen to make energy (adenosine triphosphate) from carbohydrates (sugars).
Hence, an anaerobic respiration can take place or occur in the absence of oxygen.
On a related note, an anaerobic respiration is used to regain lost energy through the actions of electron acceptor when oxygen is lacking in the body.
In conclusion, the Olympic sprinter's body will likely use anaerobic respiration to recover from her “oxygen debt.”

A day on saturn takes about 10 earths hours. Which fact would best explain this short day?
Answer:
Saturn rotates faster than Earth!
Explanation:
A day is one rotation of a planet, so a planet that rotates faster has "shorter" days.
Hope this helps!
The rotation and revolution of the planets around the Sun determine the length of day and night on the planets. The Earth takes 24 hours to rotate, Mars takes 24.6 hours, while Saturn takes 10 hours.
The fact that described the short day of Saturn is that Saturn rotates faster than the Earth.
It can be explained as:
Earth is the only habitable planet in the solar system, which rotates on its axis in approximately 24 hours. Earth takes 365 days to revolve around the Sun. Mass and density of the planet determine the rotation of the planets. Saturn is a gaseous planet, which is also an outer planet. The day length on Saturn is 10 hours long, which is shorter than the Earth hours.
Thus, Saturn rotates faster than Earth and has a shorter day length.

ATP stands for Adenosine Triphosphate. It is the compound by which energy is stored and transferred in a cell.
It is made up of a nitrogenous base, the sugar and three phosphate groups.
The compound is produce as a product of photosynthesis and use to store energy.Energy is produced from this compound in the following steps,
a cell in need of energy spends the ATP currencyfrom the three phosphorous groups attached to the tail, one is split of.ATP then becomes ADP, Adenosine Di- phosphateit is the energy holding the phosphate group that is released and is used by the body.Slowing signals between neurons is a function of __________. A. excitatory receptors B. excitatory neurotransmitters C. inhibitory receptors D. inhibitory neurotransmitters
Answer:
D
inhibitory neurotransmitters
Explanation:
Slowing signals between neurons is a function of inhibitory neurotransmitters. Neurotransmitters are the chemical messengers. Thus, the correct option is D.
What are inhibitory transmitters?Neurotransmitters are the chemical messengers in the body. These are released by the axon terminals of neuron and transmit the nerve impulse (message) to the neighboring cell (a muscle cell or a nerve cell).
There are primarily two types of neurotransmitters in the body, which are:
1. Excitatory neurotransmitter and 2. Inhibitory neurotransmitter
Inhibitory neurotransmitter have inhibitory effect on the neuron, they reduce the chances that a neuron will fire an action potential. They are responsible for slowing signals between neurons. Example: GABA (gamma amino butyric acid) is a common inhibitory neurotransmitter.
Therefore, the correct option is D.

Tim and Stephanie (from #2) are pregnant again! This time with a baby girl. They are nervous that she too may get hemophilia. Based on what you know about Tim and Stephanie, what is the probability that they do have a daughter with the disease? Show a Punnett square to support your answer.
Answer:
The probability that they will have a daughter with the disease is zero, 0.
Note: Further information about the couple is given in the previous question shown below:
Tim and Stephanie are devastated when they find out their newborn son has hemophilia - a sex-linked recessive disease. Tim is shocked because he doesn't have hemophilia, and figures if his son has it he would have gotten it from him. Is Tim correct in his thinking? Explain. Also explain what their genotypes must be in order for neither of them to have the disease but have a son who does.
Explanation:
Hemophilia is a sex-linked recessive disease which results in the inability of the blood to clot normally. The abnormal gene for the inheritance of this disease is present in the X-chromosome. Males are not carriers of this disease as any male who have the abnormal X-chromosome will always have the disease but women can be carriers of the disease if the abnormal gene is only on one XX-chromosome.
From the information provided above, it can be determined that the genotype of Tim and his wife is XY and XhX, such that the wife is a carrier (Xh is the abnormal gene for hemophilia while X is the normal gene) and Tim is a normal male.
In the event that Tim and Stephanie now have a baby girl, the likely genotype of the baby girl can be obtained using the Punnett square shown in the attachment below.
The probability that they will have a daughter with the disease is zero, 0.
what is the difference between the process of photosynthesis in dark and in sunlight
Answer: The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light.
The difference between the process of photosynthesis in dark and in sunlight is that the light reaction utilizes direct use of sunlight, it runs in the thylakoid region, and the final products are ATP and NADPH. While the dark reaction utilizes an indirect source of sunlight, it runs in the stroma region, and the final product is carbohydrates (glucose).
What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some algae synthesize their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.
