Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
Answers
Forested floodplain wetlands are rich in nutrients, and the flooding pattern from the river promotes nutrient flow from the land to the water and from the water to the land. This would resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream.
Forested floodplain wetlands are rich in nutrients.This nutrient-rich environment sustains diverse wildlife, including rare and endangered species such as the Louisiana pine snake and the black bear. Floodplains, particularly in the Mississippi Valley, also support high-value agriculture.
Because of the value of floodplain land for agriculture, there has been significant human activity in these areas over the years.
Humans have built structures such as levees, berms, and channels to control the flow of floodwaters.
The results of this human activity have been both positive and negative.
Negative effects of human activity include the fact that humans have cut off floodplains from rivers, which reduces the natural exchange of water and nutrients between the land and the water.
Without regular flooding, the nutrients that would have been deposited on the land are carried downstream by the river, and the soil in the floodplain becomes depleted over time.
This depletion of nutrients in the soil and the fact that the water no longer reaches the land can lead to long-term damage to the ecosystem and a reduction in biodiversity.
This reduced biodiversity could lead to the extinction of rare or endangered species that depend on this environment for survival.
Positive effects of human activity include the construction of levees and other structures that prevent flooding and protect people from the negative effects of flooding.
This allows people to live and farm in flood-prone areas without being exposed to the risks associated with flooding. The downside is that these structures can reduce the amount of water that reaches the land, which can lead to the depletion of nutrients in the soil.
As a result, it is essential to find a balance between protecting people and the environment.

A man and woman have a son who is color blind, a recessive sex-linked trait carried on the X chromosome, but neither parent is color blind. The woman is now pregnant with their second child. Which of the following statements is true about the second child? A daughter will be color blind because the father is a carrier of the recessive allele. A son will be color blind because the mother is a carrier of the recessive allele. A daughter will not be color blind because the father is not a carrier of the recessive allele. A son will be color blind because the father’s mother must have been a carrier for recessive allele.
Answers
Answer:
A daughter will not be color blind because the father is not a carrier of the recessive allele
A man and woman have a son who is color blind, a recessive sex-linked trait
carried on the X chromosome, but neither parent is color blind therefore the
daughter will not be color blind because the father is not a carrier of the
recessive allele
Color blindness trait is sex-linked because the trait is carried on the
chromosomes. The female have XX chromosomes while the male have XY
chromosomes. The color blind trait in the son(XY) is as a result of the
woman donating the X chromosomes which is defective and the Y
chromosome came from the man which has no issues.
in this scenario, half of their male children will have normal vision while the
other half will be color blind. The father's X chromosome is normal and all the
girls(XX) will have normal vision but will have the color blind trait in their
chromosomes because the XX chromosome are donated from both the man
and woman.

4. The inner membrane of the mitochondria is impermeable to ions. How does this fit with what
you've learned about membrane structure? Why is this important to cellular respiration?
Answers
Answer:
The inner mitochondrial membrane contains proteins involved in the electron transport chain. This chain releases energy that is then used to generate an electrochemical gradient, which is subsequently used to synthesize ATP
Explanation:
Mitochondria are membrane-bound organelles that have an inner membrane separated from an outer membrane by the intermembrane space. Moreover, the mitochondrial matrix is located within the inner membrane. The inner mitochondrial membrane contains proteins involved in the electron transport chain and ATP synthesis. Oxidative phosphorylation (electron transport chain) is the third stage of cellular respiration in aerobic organisms in which ATP is generated by transferring electrons from NADH or FADH2 to O2 by a series of electron carriers located in the inner mitochondrial membrane. The trans-membrane complexes of electron carriers are multiprotein enzyme complexes (I–V) and electron carriers (i.e., coenzyme Q10 and cytochrome c) required for the communication between complexes. The electron transport chain is coupled to proton transfer from the matrix out to the intermembrane space, thereby generating a proton gradient which is then used by ATP synthases to synthesize ATP.
Why does frozen water take on the pattern it does (hint: it has to do with water’s polarity)?
Answers

What temperature is best for enzymes ?This is because the graph shows that the rate of enzyme activity increases as the temperature increases from 0°C to 25°C. However, the rate of enzyme activity decreases as the temperature increases above 25°C. This is because the enzyme denatures at high temperatures, which means that it loses its shape and function.

The correct answer is A.
From the given graph, the condition that is best for enzyme activity can be inferred as the temperature of about 25°C.
Enzymes are organic molecules that act as catalysts and aid the biochemical reactions that occur in living organisms. Enzymes usually function under specific optimal conditions, including temperature, pH, and salt concentration. Changes in these conditions may affect the enzyme's performance and ultimately cause a decrease or cessation of the reaction's activity.Temperature, in particular, has a significant effect on enzyme activity. The reaction rate increases as the temperature rises until it reaches the optimum temperature, where the enzyme activity is at its peak. As a result, the optimum temperature promotes the highest possible reaction rate, while high or low temperatures may reduce the enzyme's efficacy and cause a decrease in the reaction rate.According to the graph, the optimum temperature for the enzyme activity is approximately 25°C. At 25°C, the relative rate of enzyme activity is maximum, indicating that the enzyme performs optimally at this temperature. In contrast, a temperature of about 0°C would be too low, causing the enzyme to freeze and become inactive. A temperature above 30°C would still be high, causing the enzyme to denature and lose its activity. Lastly, a temperature below 20°C would be too low, causing the enzyme to become inactive due to a lack of energy. Therefore, the optimal temperature for enzyme activity is 25°C.For such more questions on enzyme

Answers
Answer:
Explanation:
This question is a practical question, however the processes involved in obtaining proteins after "sacrifice" is similar.
After removing the desired muscle sample from the fish during sacrifice, the muscle sample can be stored temporarily in a phosphate buffer saline which can also help remove blood and some other contaminants around the muscle sample. The sample can then be removed and weighed with the desired mass cut into small pieces in order to achieve a smaller surface area which assists for easy homogenization and buffer interaction. The homogenization buffer (which can be a phosphate buffer) is added to this small pieces and then "vortexed" so that the buffer can interact properly with the pieces. The purpose of the homogenization buffer is to prevent osmotic damage in the muscle cells while maintaining a constant pH (depending on the protein to be obtained). After homogenization with an homogenizer, the muscle cell membrane is ruptured and the soluble proteins dissolves into homogenization buffer (which must also be soluble to the desired protein) with a mass of suspended muscle tissues also in the buffer. This mixture is then centrifuged so as to obtain the dissolved/soluble protein (in the homogenization buffer) and separate it from the suspended masses in the mixture.
