Using the data from the paraquat experiment, explain how you know that paraquat did not cause the coral bleaching.
Answer:
paraquat is a herbicide.
Explanation:
Paraquat did not cause the coral bleaching because paraquat is a herbicide which is used to kill weeds not algae. We know that coral have small algae attached to its body which is responsible for its colour so if we apply paraquat, it does not kill the algae and so coral bleaching did not occur. if we apply another chemical which kills algae so it causes coral bleaching and the coral becomes white.

An epeirogenic change:
O creates very high mountians
O
leaves the crust undeformed
O
results in highly volcanic regions
occurs when rock layers are lifted out of sequence.
Answer:
leaves the crust undeformed
Explanation:
An epeirogenic change leaves the crust undeformed. It is significantly different from an orogenic change which makes the crust deformed.
This change produced by epeirogenesis is notable in stable continental regions called a craton. Long wavelength folds leaving the landform rolling and undulating are typical signatures of this deformational patterns. In an orogenic deformation, there is a noticeable change in the landform.High average daily temperature and heavy annual precipitation are found in a?

C. Has less than 10 bp per turn of its helix.
D. Is more negatively charged due to additional phosphates per turn of the helix.
E. Is found in most cells.
2.)How many complete rotations would most likely correspond to a positively supercoiled DNA molecule that is 100 bp in length?
A.) 0
B.) 5
C.) 10
D.) 15
E.) 100
Answer:
1.
C. Has less than 10 bp per turn of its helix.
2.
D.) 15
Explanation:
Negatively supercoiled DNA
(deoxyribonucliec acid) is the twisting against the helical conformation which is a twist in a left handed direction that loose and straightens the helix at low twisting stress, and knot the DNA into negative supercoils at high twisting stress.
Supercoiling will occur where the DNA helix must uncoiled for the function of a macromolecular assembly.
Supercoiling allows DNA to be packed into small spaces, It allows for more negative charge and can be found in many cells. But it does not have less than 10 bp per turn of its helix.
15 rotations will correspond positively supercoiled dna molecule of 100base pair.

Explain why the biodegradation of plastic might be more hazardous to the environment than the presence of plastic as marine
debris.
Answer:
simplified: the toxic breakdown of plastics have potential to do more damage than marine debris.
Explanation:
while plastic marine debris is hazardous and dangerous to marine organisms, the toxic breakdown products of plastics have the potential to do even more damage.
The biodegradation of plastic might be more hazardous to the environment than the presence of plastic as marine debris, as the plastic in the marine environment causes many harmful effects to the animals, such as when it enters the marine animal's body.
What are the hazards of marine pollution?Because of the world's overpopulation, rapid industrialization pollutes various natural sources such as water bodies and land, but chemicals, plastics, and debris cause more pollution in marine or water bodies that have a variety of negative impacts on marine life and ecosystems. It causes habitat damage, and contamination of seafood has a negative impact on human health as well as economic growth.

Besides organic pollutants, dead zones are also affected by nitrogen compounds. Denitrifying bacteria in the anoxic dead zones can use nitrates and nitrites as electron acceptors, thereby generating nitrous oxide, a potent greenhouse gas. What is the term used for this process?
a. assimilatory nitrogen reduction
b. dissimilatory nitrogen reduction
c. nitrification
d. nitrogen fixation
Answer: The correct answer to the question bus option B
DISSIMILATORY NITROGEN REDUCTION .
Explanation: When we talk about Dissimilaritory nitrogen reduction we simply mean an alternate form of respiration which occurs in the anoxic grown bacteria example purple photosynthetic bacteria.
Dissimilaritory nitrogen reduction is actually a type of denitrification which entails the denitrifying bacteria using nitrates or nitrites as electron acceptor and then reduce them to nitrogen gas. A series of intermediates are formed in this process of which Nitrous oxide is one of them, Nitrous oxide is a green house gas.
However,the main difference we can see between assimilatory and dissimilatory nitrogen reduction is that in the assimilatory pathway of nitrate reduction, ammonia will be formed which is utilized for the biosynthesis as a source of nitrogen. While in dissimilatory pathway, ammonia formation do not take place.

How is detritus important to wetland ecosystems?
Answer:
Detritus is important too wetland ecosystems, because it provides a food source for a variety of aquatic organisms.
Explanation:
Plants' stem and leaves break down in the water and make organic material that is fed by the fishes and provide a good source of the organic compound used for energy and is important for wetland ecosystems.
What is detritus?In the water, dead plant leaves and stems degrade into small particles of organic material called "detritus." This enriched material feeds a variety of small aquatic insects, shellfish, and small fish.
Which then in turn feed larger predatory fish, lizards, amphibians, birds, and mammals. Detritus, in ecology, is matter composed of leaf and other plant parts, animal remains, waste products, or other organic particles.
Much energy may flow through to the detritus food chain as opposed to the grazing chain or pathway detritus, in ecology, waste products, and other organic debris that falls over onto soil or into bodies of water.
Therefore detritus is organic material made from a leaf of plants that are consumed by small fish and small fish is eaten by larger fish provide important to the wetland ecosystem.

Which action is the best way to turn an electromagnet off?
Answer: 1) The strength of the electromagnet increases → Place a magnetic core inside the coil of wire
2) The electromagnet turns off → Turn off the battery supply
3) The poles of the electromagnet reverse → Change the direction in which the current flows
Explanation:
when current passes through a coil it behaves a an electromagnet.
Magnetic field strength is given by
B = μ N I
N is no of turns and
I is the current through coil
μ is permeability of the medium or core in the coil.
1). Magnetic core increase permeability μ so it will strengthen magnetic field:
B = μ N I
2). When the battery turns off current becomes zeroi.e I=0
So B = μ N * 0
⇒ B = 0
so electromagnet turns off
3). Direction of magnetic field can be determine by right hand rule, i.e curl the fingers in the direction of current, thumb will point in the direction of north pole.
so changing current direction will change direction of magnetic field.

They have genetic material from two parents is true about sexual reproduction.
What is sexual reproduction?
Sexual reproduction is the process of combining the genetic information of two individuals of the opposite sex to create new organisms. Genetic information is carried on chromosomes within the nuclei of gametes, which are specialized sex cells.
These gametes are called sperm in males and eggs in females. During sexual reproduction, two gametes participate in a fusion process called fertilization to create a fertilized egg.
The fertilized egg is the progenitor cell of the embryonic offspring and receives half of its DNA from each parent. In humans, the fertilized egg contains 46 chromosomes.
Therefore, They have genetic material from two parents is true about sexual reproduction.

If a population is steady at its carrying capacity, but then a group of organisms from that species moves in to the same space occupied by the original population, what will happen to the carrying capacity of the combined population?
Answer:
It will remain relatively stable
Explanation:
The carrying capacity (k) of an environment is a factor that represents the maximum number of organisms of a particular species such environment can support based on the resources it has.
Below the carrying capacity, the population of a species still has the potential to increase due to resource availability, and above the carrying capacity, the population has the potential to reduce due to the overstretching of the available resources. Factors that keep the population from expanding significantly beyond the carrying capacity include competition for resources, natural disasters, disease outbreaks, etc.
Hence, if a population is steady at its carrying capacity and a group of organisms from that species moves into the same space occupied by the original population, the carrying capacity will only increase temporarily before factors such as competition and natural disasters operate to bring the carrying capacity to the normal level.

Explain why it is important to be skeptical of statistical results reported in the media.
Answer:
Firstly, many statistics are taken from a small group of people used to represent the general population. Say a news channel reported that 81% of teenagers in America were planning on going to a four-year college. This statistic is most likely taken from a randomly selected group of teenagers, and calculated with a margin of error. Because after all, it's nearly impossible to survey every single teenager in America. This can lead to some statistics that are not really representative of the actual percentage of people. This only gets more likely the larger the general population being "surveyed" is. Another reason is that the media is not always truthful with statistics. Things can be altered and not many people will notice. Hope this helps!
