(30 points) Mosquitoes can carry and transmit many diseases to humans. In the past, the insecticide DDT was heavily used to reduce mosquito populations in order to reduce instances of disease transmission. However, after some time, mosquito populations developed a resistance to DDT, which made the DDT less effective in reducing mosquito populations.
Based on what you’ve learned about natural selection, in 3–5 sentences, describe how mosquitoes may have come to develop this resistance.
Mosquitoes resistant to DDT are also immune to mosquito net insecticide. A single genetic mutation causes resistance to DDT and pyrethroids according to new research in the diary Genome Biology.
What is DDT and why was it banned?Dichlorodiphenyltrichloroethane (DDT) is an insecticide used in agri company . The United States prohibited the use of DDT in 1972. Some nations outside the United States still use DDT to manage of mosquitoes that laid malaria.
Thus, Mosquitoes resistant to DDT are also resistant to mosquito net insecticide.

Mosquitoes may have developed resistance to DDT through the process of natural selection. Initially, within a mosquito population, there may have been genetic variation in their response to DDT exposure.
Some mosquitoes may have possessed genetic traits that made them more tolerant to the effects of DDT, while others may have been more susceptible. When DDT was heavily used, the susceptible mosquitoes were killed, while the tolerant ones survived and reproduced. Over time, this led to an increase in the proportion of mosquitoes with the genetic traits for DDT resistance, as they were the ones passing on their genetic information to the next generation. This process of natural selection favored the survival and reproduction of mosquitoes with DDT resistance, resulting in the development of a resistant population.

Do you think human population growth is a concern in the United States? Explain your reasoning.
Answer:
In my opinion, Yes the human population growth is a concern in the United States because Human population growth impacts the Earth system in a variety of ways, including:
Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans. The process of removing resources, in turn, often releases pollutants and waste that reduce air and water quality, and harm the health of humans and other species.Increasing the burning of fossil fuels for energy to generate electricity, and to power transportation (for example, cars and planes) and industrial processes.Increase in freshwater use for drinking, agriculture, recreation, and industrial processes. Freshwater is extracted from lakes, rivers, the ground, and man-made reservoirs.Increasing ecological impacts on environments. Forests and other habitats are disturbed or destroyed to construct urban areas including the construction of homes, businesses, and roads to accommodate growing populations. Additionally, as populations increase, more land is used for agricultural activities to grow crops and support livestock. This, in turn, can decrease species populations, geographic ranges, biodiversity, and alter interactions among organisms.Increasing fishing and hunting, which reduces species populations of the exploited species. Fishing and hunting can also indirectly increase numbers of species that are not fished or hunted if more resources become available for the species that remain in the ecosystem.Answer:

Explain how (will they increase/decrease in size) and why( will water be leaving the potato by
osmosis or moving into the palato by osmosis) tube 1 and tube 2 would look different after one
hour.
The size of tube 1 will eventually rise due to the entry of water. As a result of this, it will swell due to osmosis. While tube 2 would stay the same as the initial size.
What is Osmosis?Osmosis may be defined as the process through which the movement of solute molecules may take place from a lower concentration of solution to a higher concentration of solution through a semipermeable membrane. It is also called the net movement of water across a semipermeable membrane.
According to the context of this question, the actual reason for this increase in the size of the tube is due to osmosis, water will enter tube 1 in order to dilute the sucrose. Due to this, tube 1 may increase in size. But on contrary, the size of tube 2 remains the same because there is no need for dilution of the solution in which it is placed.
Therefore, the size of tube 1 will eventually rise due to the entry of water. As a result of this, it will swell due to osmosis. While tube 2 would stay the same as the initial size.

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins?
osmosis
passive transport
active transport
diffusion
Answer:
osmosis
Explanation:
I'm so sorry if I'm wrong, I'm pretty sure that's it though
The movement of particles that would be most affected by a disorder causing damage to carrier proteins is active transport.
What is active transport?Active transport is a cellular process that requires the use of energy to move particles across a cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. Carrier proteins play a crucial role in active transport by facilitating the movement of specific molecules or ions across the cell membrane. These proteins bind to the particles being transported and undergo conformational changes that allow them to move the particles across the membrane.
If there is damage to the carrier proteins due to a disorder, their ability to bind to and transport particles may be compromised. This impairment can disrupt the active transport process, leading to a decrease or complete loss of the movement of particles against their concentration gradient. Consequently, the normal cellular functions that rely on active transport, such as nutrient uptake, ion regulation, and maintenance of cellular homeostasis, would be significantly affected.
