Answer:
Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase.
Explanation:
The trait that would make an individual ( pest ) survive in a pest population that feeds on pest-resistant plants is : Possession of Pesticide resistant genes
In a pest infected population most pests can be eliminated with the use of pesticides. therefore when pesticides are administered in the population, the pests that posses genes resistant to pesticides will survive and continue their reproduction cycle. while pests without pesticide resistant genes will be eliminated.
Hence the trait that a pest( individual ) should posses to survive in a pest population is; the Possession of Pesticide resistant genes .

In an ecosystem, a group of birds eat fruit from a tree. When the birds drop the fruit on the groundthe mice ea the fruit. Seeds are spread around the area by both the birds and mice and new trees grow. What is this an example of ?
Answer:
The correct answer is - interdependence.
Explanation:
In this ecosystem, all the organisms, tree mice, and birds all depend on one another for their food and growth. Birds get their food from fruits from the tree and the fruits that dropped by the birds to the ground used by the mice for their food.
In return mice and birds spread the seeds of the tree to the area which helps in the growth of the more trees. This relationship among the organisms is an example of interdependency.

What conditions are necessary for rocks to melt?
Answer:
In explanation.
Explanation:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
The rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts. The different types of rocks need different temperatures.
What is the effect of temperature on different substances?Temperature plays an important roles in different substances, such as high and low temperatures, each with its own set of tasks. The high temperature can melt the solid substance into a liquid, and further heating converts the liquid into gas. Because of the high pressure and temperature in the earth's core, the rock is in a molten state, but when it comes out of the earth's core, after solidifying, it converts into solid rock. The low temperature converts the liquid into a solid, and food preservation is carried out by this process.
Hence, the rock can be melted when high pressure and high temperature are applied to it, and due to the compression relaxation, the rock melts.

There are now several effective antimalarial drugs that can treat people who have malaria or prevent them from getting the disease altogether. Predict what will happen to the frequency of the sickle cell allele over the next 100 years as these drugs become more widely used by people living in areas where malaria is endemic: _____________ Predict what will happen to the frequency of the sickle cell allele over the next 100 years in areas like Boston MA, where there is no incidence of malaria: __________ stay the same ; stay the same decrease ; increase increase ; increase increase ; decrease decrease ; decrease
Answer:
decrease, decrease
Explanation:
By using antimalarial drugs in order to prevent malaria, the frequency of the sickle cell allele decreases in both areas where malaria is endemic and the areas where no incidence of malaria occurs because there is no necessity of sickle cell allele in the population to prevent malarial disease. Sickle cells have high significance in prevention of malarial diseases so when there is no malaria happens in the population so there is no need for it and the allele slowly removed from the population and decrease occurs in its frequency.

If sea lamprey increase in population and decrease the native fish population, the sea lamprey population will eventually collapse (decrease rapidly). This would be an example of _______ feedback. 1. Positive 2. Negative 3. Neutral 4. None of the above
Answer:
Negative feedback
Explanation:
Feedback mechanism is activated due to the change in the system that result into an output.
A negative feedback mechanism is a pathway that is caused by deviation in the output that result in a change in output direction which is usually opposite to the initial deviation.
The process of feeding of sea lamprey on the fish started as a normal pathway the deviation started when they could not feed on the fish again as a result of reduced population and they start dying of hunger. It is a negative feedback

Which of the following substances is/are involved in
oxidative phosphorylation of cellular respiration?
Answer:
the answer will be
ADP
Oxygen
ATP
so its all the above
Explanation:
The substances involved in oxidative phosphorylation are the electron transport chain, oxygen, and ATP synthase.
The substances involved in oxidative phosphorylation of cellular respiration are:
Electron transport chain: It consists of a series of protein complexes located in the inner mitochondrial membrane. Electrons from carrier molecules, such as NADH and FADH2, are passed along the electron transport chain, resulting in the generation of a proton gradient.
Oxygen (O2): Oxygen acts as the final electron acceptor at the end of the electron transport chain. It combines with hydrogen ions to form water (H2O).
ATP synthase: This enzyme is located in the inner mitochondrial membrane and utilizes the energy from the proton gradient to generate ATP through the process of chemiosmosis.
