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.

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.

Explain what scientists might be able to learn about the seawater that existed millions of years ago by studying rocks that came into contact with seawater at that time in the past . Use evidence from the text to support your inference.
Answer:
About composition of water and organisms that lives there.
Explanation:
scientists might be able to learn about the composition of seawater that was present millions of years ago if we study those stones that comes in contact to that ancient seawater because the traces of particles still present on it. This study provides valuable information about ancient times of earth and its natural resources. These rocks also provides animals that were present in that sea water at that time.
Geologists using the aspects of geology and paleontology can study and analyze the evolutionary, physiology and ecological relation of plants, animals and other microorganisms with abiotic and other biotic factors.
The scientists will be able to understand the composition of the organism and the water that resided in the region.
This inference can be supported by:
The stones and rocks present in the seawater will depict the characteristics as they will have traces of particles present on them from the past years.This evaluation will provide insights into the natural resources and organisms present during the ancient times on the planet.This will also give data about the organism living in aquatic or terrestrial areas.Therefore, it will give the composition of water and organisms.

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.
