If mutated DNA Sequence #1 occurred in a single cell on the membrane of a fish, how might it impact the organism?
Answer and Explanation:
This would cause defective proteins to be created in the body that would not form the fish membrane correctly and promote problems with the control and functioning of that membrane. This could harm the organism in many activities, limit its life expectancy, cause discomfort and cause a strain that presents the same problem, since these flaws can be inherited genetically.
A mutated DNA sequence is a DNA molecule that has nucleotides in the wrong order, which causes a mutation and does not allow the correct formation of proteins.

Use the student's hypothesis to predict which parachute, A, B or C, will hit the ground first. Give a reason for your answer?
Answer:
The heavier will come first to hit the ground.
Explanation:
That parachute will come faster and hit the ground first which has more weight than other parachutes because the heavier objects comes to the earth at faster rate as compared to light objects. So if all the three parachute has same size and shape but difference in weight than the heavier one comes to the ground first as compared to other two parachutes.

A.Chlorophyll
B.Anaerobic
C.Flaccid
D.Aerobic
E.Turgor
Answer: E. Turgor
Explanation: can i help u with more?
Turgor pressure gives the non-woody plants their shape. Thus, the correct option is E.
What is Turgor pressure?Turgor pressure is the force which is present within the cell that pushes the plasma membrane against the cell wall. It is also called as hydrostatic pressure, and also defined as the pressure in a fluid which is measured at a certain point within itself when the fluid is at equilibrium.
Generally, the turgor pressure is caused by the osmotic flow of water and occurs in the plants, fungi, and bacteria which contain cell wall. The phenomenon is also observed in the protists which have cell walls. This system is not seen in the animal cells, due to the absence of a cell wall in the cell which would cause the cell to lyse when placed under too much pressure condition.
Therefore, the correct option is E.

Explain surface runoff. HELP PLSSSSSSS
Explanation: Surface runoff is water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle. Runoff that occurs on surfaces before reaching a channel is also called overland flow. A land area which produces runoff draining to a common point is called a watershed
Explanation:
surface runoff also called soil erosion is the washing away of top soil by the actions of moving water after rainfall. It occurs when the surface of soil is exposed to direct rainfall.
One theory of early life on Earth states that the first life forms did not use oxygen for respiration and were unable to make their own food. Based on this theory, which types of organisms were most likely present?
aerobic, autotrophic bacteria
aerobic, heterotrophic bacteria
anaerobic, autotrophic bacteria
anaerobic, heterotrophic bacteria
Answer:
Early organisms would have to be anaerobic, as air was likely non existent. This rules out the first two options.
Autotrophic can be called producers, and heterotrophic can be called consumers.
The question states that "did not use oxygen for respiration and were unable to make their own food"
Only one option satisfies the question:
anaerobic, heterotrophic bacteria

Anaerobic, heterotrophic bacteria

Infectious diseases have an easier time spreading now than they did several hundred years ago. What about society has changed that makes this possible? Describe at least TWO reasons.
Answer:
see below :)
Explanation:
Infectious are more easily spread nowadays becuse of an increased population. The more the population increases, the bigger the advantage an infectious disease has. As of right now, because everyone is wearing masks, their immune systems are being weakened. Another reason for this is because of the increase in chemicals in our foods, which are now being transferred to our bodies. All of the medications people are taking also have an affect on the spread of disease; it gives diseases a chance to mutate.

A certain microscopic single-celled organism is important to the dairy industry because when placed in milk, it consumes sugars in the milk and releases substances that react with the milk, adding flavor and thickening it. What kind of organism is this?
Answer:
I think its a type of bacteria but im not really sure, is there any choice options?
Explanation:
The dairy business depends on bacteria tiny single-celled organisms because, when added to milk, it consumes milk sugars and produce chemicals that react with the milk to taste and thicken it.
How dairy industry use bacteria?Temperature, pH, water activity, salt-in-moisture levels, and other factors all have a significant impact on how quickly bacteria thrive in dairy goods.
In order to acidify the cheese milk before and during the preparation of dairy foods, starter microorganisms must be used. Streptococcus thermophilus, Lactobacillus sp., and Lactococcus lactis.
However, dairy firms now often standardize the process by adding domesticated bacterial cultures, such as strains of Lactococcus lactis, Streptococcus thermophilus, and Lactobacillus sp. it can be done by naturally existing lactic acid bacteria in the milk.
Therefore, the dairy business depends on bacteria tiny single-celled organisms.

A fire sits 72 feet from the abs of 125 foot tall building. Find the angle of Evel at ion from the fire to the top of the building
Answer:
60°
Explanation:
From the attachment,
Opposite side of the triangle= 125 feet
Adjacent=72 feet
Angle of elevation= (θ)
From trigonometry,
Tan (θ)= Opposite side /Adjacent adjacent
Where
(θ)=angle of elevation
If we substitute to above expresion we have
tan(θ)= 125/72
tan(θ)= 1.736
Tan^-1(1.736)=60°
θ= 60°
Hence, the angle of Evel at ion from the fire to the top of the building is 60°
