Computer simulation is becoming a commonly used process to efficiently model and evaluate the impact of a variety of proposed solutions when facing a complex real-world problem. Reasons for using computer simulation over actual production of possible solutions include all except:
A) costs associated with testing and prototyping too high
B) computers are not as trustworthy as actual prototypes are
C) trial system would not withstand significant testing desired
D) time necessary to acquire and analyze results prohibitively long
Answer:
The correct answer is option B) "computers are not as trustworthy as actual prototypes are"
Explanation:
It is false to affirm that results obtained from computer simulations towards looking for solutions of real-world problems are not as trustworthy as results obtained from actual prototypes. In most cases, computer simulations had proved to be reliable, particularly when the programers use validating arithmetic and algorithms. There are multiple companies dedicated to develop computer simulations to solve real-world problems, which are constantly used and tested in scientific investigations.

Explain photosynthesis in a paragraph.
Answer:
Photosynthesis is the synthesis of glucose from carbon dioxide and water in the presence of sunlight and chlorophyll with oxygen as a by-product it occurs in green plants,photosynthetic bacteria and some algae it is an anabolic(building) process and nearly all life depends on it it comprises many coordinated biochemical reactions that are necessary for the survival of the species it is divided into two phases 1 light reaction(Z-scheme) 2 dark reactions(Calvin cycle)
Explanation:
I hope this will help you:)
Answer:
Photosynthesis is the process through which autotrophs are bale to produce their own food. The Process is named so because photo means sun's light and synthesis means creating. It involves the Plants or other autotrophs absorbing the sun's light and also carbon dioxide released into the atmosphere by respiration. As a result of Photosynthesis, we obtain what is known as oxygen. This is, in fact, the biproduct of the process. Mainly, Photosynthesis occurs due to the presence of Chlorophyll which give leaves their green colour.
Key:
Autotrophs: Those who have the ability to produce their own food.
Biproduct: The extra result of a scientific equation.
Chlorophyll: a green pigment, present in all green plants and in cyanobacteria, etc.

A DNA template is used to create an mRNA strand.
An mRNA template is used to create a DNA strand.
A DNA template is used to create a ribosome.
An mRNA template is used to create a tRNA strand.
Answer:
A DNA template is used to create an mRNA strand.
Explanation:
Transcription basically means a written or printed representation of something, if we connect that analogy to DNA, we are using the DNA as our template to write/create an mRNA strand out of it, basically transcribing the DNA.
What is the role of DNA template?
The DNA template is used by RNA polymerase to produce a strand of RNA with a nucleotide sequence that is the same as the coding strand for the production of functional RNA units and mRNA for making proteins.
How do you get mRNA from DNA?
mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II.

Your classmate describes a growing baby as “a ball of multiplying cells that eventually grows large enough to form a baby.” Explain why this statement isn’t completely accurate.
Answer:
Please, see the answer below.
Explanation:
The statement is inaccurate because a growing baby is not just a ball of multiplying cells that eventually grows large enough to form a baby.
After fertilization and the formation of a single-cell zygote, the zygote continues to divide to form a ball of cells. However, at some points, the cells start to differentiate to give rise to various organs that make up the baby.
Without differentiation, there is not way the dividing cells will give rise to baby. Hence, a growing baby should be rather viewed as a ball of multiplying cells that eventually differentiates to form a baby.
Answer: Embryos start as a ball-like structure of rapidly dividing cells. However, at a certain point in development, these cells diversify and bind together to form larger structures, such as tissues, organs, and, eventually, full systems.

How are viruses different from bacteria?
Answer:
Your correct answer is option A. Viruses contain only RNA
Explanation:
Viruses are smaller than any bacteria. In fact, the largest virus is actually way smaller than the smallest bacterium ever. All viruses have a protein coat and a core of genetic material of either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to the cells. In most cases, they definitely reprogram the cells to make new viruses until the cells burst and die. In other cases, they turn normal cells into malignant or cancerous cells. Also unlike bacteria, most of the viruses do indeed cause disease and they are quite specific about the cells they attack.
The correct statement that highlights the difference between viruses and bacteria is "Viruses cannot survive outside a host." The correct option is B.
Viruses are obligate intracellular parasites, meaning they require a host cell to carry out their life cycle.
They do not possess the necessary cellular machinery or metabolic processes to replicate on their own.
Viruses invade host cells and hijack their cellular machinery to reproduce.
When a virus infects a host, it injects its genetic material into the host cell.
The viral genetic material then takes control of the host cell's machinery and directs it to produce new virus particles.
Viruses can have either RNA or DNA as their genetic material, but not both. Viruses have RNA genomes, while others have DNA genomes.Viruses are significantly smaller than bacteria. Viruses are typically composed of a nucleic acid core (either RNA or DNA) surrounded by a protein coat called a capsid. Viruses are not cells and do not have cellular structures. They are considered acellular particles because they lack the essential characteristics of living organisms.Thus, the correct option is B.

A spring was at its resting position where it is attached to a wall at its left side and a block at its right side as shown below. The spring constant is k=75.0\,\dfrac{\text N}{\text m}k=75.0
m
N
k, equals, 75, point, 0, start fraction, start text, N, end text, divided by, start text, m, end text, end fraction. The block is moved leftwards and the spring's right end is displaced from the position of 0.250\,\text m0.250m0, point, 250, start text, m, end text to 0.150\,\text m0.150m0, point, 150, start text, m, end text where it is held in place. All positions are measured from the origin OOO of the wall.
Answer:
The force of spring will be "3.75 N". The further explanation is given below.
Explanation:
The given values are:
Spring constant, K = 75.0 N/m
x₁ = 0.200 m
x₂ = 0.150 m
So that,
⇒ [tex]x=x_{1}-x_{2}[/tex]
⇒ [tex]=0.200-0.15[/tex]
⇒ [tex]=0.05 \ m[/tex]
Now,
Force of spring will be:
⇒ [tex]F=K\times x[/tex]
On putting the estimated values, we get
⇒ [tex]=75\times 0.05[/tex]
⇒ [tex]=3.75 \ N[/tex]
Answer:
−8.25N
Explanation:
Hooke’s law says the restorative spring force is directly proportional to the change of the spring length x on top, but is opposite in direction to the change in spring length.
emphysema and asthma are respiratory disorders that may both be attributed to smoking; they also share many symptoms in common. As a physician, how would you distinguish between these two disorders when diagnosing a patient? explain.
Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged. Chronic bronchitis is when the tubes that carry air to your lungs (bronchial tubes) get inflamed. Smoking is the most common cause of those conditions (and COPD).
Some people have asthma and COPD at the same time. If you have symptoms of both diseases, your doctor may call it asthma-COPD overlap syndrome.
People who smoke or breathe in pollution or chemicals at work for many years have higher chances of having COPD. That's why the condition often starts in middle age or later in life.
Asthma is sometimes caused by gene changes that are passed down through families. If one of your parents has the disease, you're more likely to have it. Symptoms often start in childhood.
Since asthma and COPD both make your airways swell, they both can cause shortness of breath,coughing, and wheezing.
One main difference is that asthma typically causes attacks of wheezing and tightness in your chest. COPD symptoms are usually more constant and can include a nasty cough.
To figure out which condition you have, your doctor will start with a physical exam and questions about your medical history. They’ll look at your nose and throat and listen to your lungs with a stethoscope. Your doctor will also want to do a test called Spirometry that checks how well your lungs work.

Answer:
vaccines inject either weaker strain or dead viruses into the body in order for the immune system to produce antibodies that will help fight off the disease in the future.
hope this helps
Answer:
Vaccines help develop immunity by imitating an infection.
It causes the immune system to produce T- lymphocytes and antibodies.
once the imitation infection goes away, the body is left with a supply of T- lymphocytes, as well as B- lymphocytes that will fight the disease in future.
