Answer:
algal growth due to eutrophication
Explaination:
Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.

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.

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.

An earthquake originated in New York State. The P-wave travel time for this earthquake was recorded in the data table below for four widely separated seismic stations, A, B, C, and D If the first P-wave arrived at seismic station A at 10hrs:22min:30sec, what was the origin time for the earthquake?
The provided question is incomplete as it lacks the essential information to give answer. however, the complete question is attached as image.
Answer:
The correct answer is option : c. 10hrs: 14min: 10sec.
Explanation:
The question provides the following information to answer the question:
The P wave takes time to reach Seismic station A = 8 min:20 sec
P-wave arrived at seismic station A at : 10hrs:22min:30sec
So, the origin time of earthquake would be: 10hrs:22min:30sec - 8 min:20 sec = 10hrs: 14min: 10sec.
Thus, the correct answer is : 10hrs: 14min: 10sec.

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.
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.

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.
