In a strand of DNA, if the percentage of thymine is 30%, what would the percentage of cytosine in the same DNA strand be?
Answer: 20%
Explanation:
I haven't learned this exactly yet, but if there is 30% of thymine, then there has to be 30% of adenine because they match. That would leave 40% for other Guanine and Cytosine, and since they also match that means that it is exactly half, meaning that there is 20% Guanine and 20% Cytosine.

What are some of the issues that come with catching shrimp in the wild? What are some of the problems associated with fish farms?
Answer:
Explanation:
There are many issues that can be thought of when it comes to both wild shrimp catching and fish farming. When catching wild shrimp, many fishers like to overfish. This can cause shrimp population levels to drop, and cause them to become endangered. There are also parasites, such as tapeworms in brine shrimp, which turn them bright red and make them very easy prey for bird species and such, and Orthione griffenis, better known as Griffen's isopod, which is a small isopod that attaches to a shrimp's gills and sucks the life out of them. Not only are these revolting, they're causing shrimp species to plummet.
Fish farming is known of, and is a very profitable business. However, there are many concerns that can arise. One of these concerns is unethical treatment of the fish. Some farmers may starve or overfeed their fish, meanwhile others may overbreed them. There's also concerns of how the fish are acquired. If fish are taken from the wild to be farmed, some may see this as cruel or inhumane. Quality of life for the fish is a large concern, as if a fish is unhappy or ill, it can cause the consumer to fall ill from the product, which wound cause trouble for many.
There are many more issues that could arise, but overall, these are some of the most major issues when it comes to shrimp catching and fish farming.

Each group of three mRNA bases specifies a particular
A.nucleic acid.
B. protein.
C.amino acid.
D.gene.
Answer: C its Amino Acid
Explanation:
Answer:
Amino acids
Explanation:
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon.

Describe your diagnosis for the patient. How did the chlorine gas affect concentration difference, diffusion distance, and surface area in the patient’s lungs? Explain how these affected the diffusion rate.
The concentration difference and surface area lead to decrease but the diffusion distance increases due to application of chlorine.
The difference in the concentration of a substance between two regions is known as the concentration gradient.
Surface area is the total area that the surface of the object occupies.
Diffusion rate is defined as the change in the quantity of diffusing molecules inside the cell in a specific period of time.
The chlorine gas greatly affected the concentration difference because it lowers the value. The gas increases the diffusion distance but decreases the surface area of the patient's lungs. The decrease in the concentration difference leads to slower the diffusion rate.
It is because there is less difference in the concentration of both regions i.e. lungs and the surrounding atmosphere and when there is equal amount on both sides the diffusion of gas molecules stopped so we can say that decrease occur in the concentration difference and surface area but increase occur in the diffusion distance

Explain how the grunion depends on the changes in tide for the survival of its species.
Answer:
These creatures depend on the sea water for nutrients, protection and to move about. At low tide,many of these creatures are exposed to the air, leaving them at risk of predator attacks andoxygen depletion. The whole eco-system of the tide pools would simply not exist without theconstant movement of the tides
Explanation:
The grunion depends on the changes in tide for the survival of its species.
It is because the grunion comes to the beach to lay eggs with the help of high tides. Grunions spawn on the beaches when the tides are at their highest during the full moon and the new moon. The high tides ensures that the eggs will submerged which is important because it allows them to get enough oxygen which is necessary for its survival so we can conclude that grunion depends on the tide for the survival of its species.

Explanation:
1. A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.
Dependent Variable: ______________________ Control Group: ____________________________
Independent Variable: _____________________ Experimental Group: _______________________
Answer:
Independent variable: Jazz
Dependent variable: Amount of time used to sleep
Control group: The group that was placed in a quiet room
Experimental group: The group that was placed in a room where jazz music played softly
Explanation:
In an experiment, the independent variable refers to the variable being changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment, the independent variable is the JAZZ used.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the AMOUNT OF TIME SPENT SLEEPING.
Control groups are the groups in an experiment that do not receive the experimental treatment (jazz music). Hence, the GROUP THAT WAS PLACED IN A QUIET ROOM is the CONTROL GROUP.
Experimental group, on the other hand, is the group that receives the experimental treatment in an experiment. In this case, the experimental group is the GROUP THAT WAS PLACED IN A ROOM WHERE JAZZ MUSIC WAS PLAYED SOFTLY.

What are the two types of venomous snakes? Describe each type and include an example.
Answer:
The King Cobra and the Black Mamba
EXPLANATION:
The black mamba is a species of highly venomous snake belonging to the family Elapidae. It is native to parts of sub-Saharan Africa. First formally described by Albert Günther in 1864, it is the second-longest venomous snake after the king cobra; mature specimens generally exceed 2 m and commonly grow to 3 m
The king cobra, also known as the hamadryad, is a venomous snake species in the family Elapidae, endemic to forests from India through Southeast Asia. It is threatened by habitat destruction and has been listed as Vulnerable on the IUCN Red List since 2010. It is the world's longest venomous snake.
Answer:
The two types of venomous snakes are Elapine snakes, and Viperine snakes. Elapine snakes have shorter fangs and venom that paralyzes the respiratory system. Cobras and coral snakes are Elapine snakes. Viperine snakes have longer hollow fangs and venom that attacks red blood cells. Rattlesnakes are viperine snakes.
