What two diseases have been studied together that provide evidence of evolution in
humans?
A)malaria and ebola
B)sickle cell anemia and malaria
C)cytochrome c disease and plasmodium fever
D)iron-deficient anemia and yellow fever
Answer:
sickle cell anemia and malaria
Explanation:
Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.
The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.
What is sickle cell mutation?
The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.
The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.

Yuki has a bowl of ice. She places the ice in a warm room and watches as it melts into liquid water. Yuki then places the liquid water over a Bunsen burner and heats it until it vaporizes. Explain what happens to the water molecules in Yuki's experiment; from the beginning to the end of the experiment.
Answer:
ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

by the data if...
A. traits independently assorted in
approximately a 9:3:3:1 ratio.
B. the traits for white fur and red eyes were
always inherited together.
C. all the F1 offspring had the same phenotype.
Answer: B
the traits for white fur and red eyes were always inherited together.
Explanation:
The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.
What is law of independent Assortment?The law of independent assortment selects alleles of two extra genes into gametes independently of each other.The allele acquired for one gene is unrelated to the allele obtained for another.Mendel's experiment constantly shown that the progeny's distinctive combinations are always unique from their parents'.He formulated the Law of Independent Assortment on this premise.So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time?
Answer:
Determine how many groups you will have.
Prepare ping-pong balls.
Collect egg cartons.
Prepare the egg cartons.
Prepare “energy tokens.”
Post signs in the classroom.
Prepare filled H20 and C02 “molecules.”
Explanation:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
Answer:
This new model may better explain the elements required for photosynthesis to occur. Sunlight, water, and carbon dioxide are required for the plant to produce its own food. Someone who is unfamiliar with the process of photosynthesis must begin with the basics and then build on this knowledge.

Which of these statements explains why the plants in Groups E and F died? The high sugar content caused too much water to move into the root cells. The high sugar content caused too much water to move into the root cells. The high sugar content clogged the pores in the cell membranes. The high sugar content clogged the pores in the cell membranes. The high sugar content prevented the plant from capturing energy. The high sugar content prevented the plant from capturing energy. The high sugar content caused too much water to move out of the root cells.
Answer:
The high sugar content caused too much water to move out of the root cells.
Explanation:
Too much causes transpiration to occur, in this case too much water killed the plant.
The statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.
What do you mean by High sugar content?
High sugar content in plants may be defined as the amount of carbohydrates (glucose) and their components get accumulated in the different parts of the plants in a high ratio. It also affects the rate of photosynthesis.
High sugar content leads to the loss of water (transpiration) in plants. In this condition, water loss is maximum which results in the scarcity of water in the root cells. And hence the plant died.
Therefore, the statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

Which 3-carbon molecule is one of the final products of glycolysis? (1 point)
oxaloacetic acid
NAD+
O pyruvic acid
O ADP
Answer:
pyruvic acid
Explanation:
Glycolysis involves the breaking of glucose molecule into two molecules of a 3-carbon compound called pyruvate (pyruvic acid) & two other molecules of ATP
Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Thus, option C is correct.
What is the significance of glycolysis?Glycolysis is the metabolic process by which glucose produces cellular energy, glycolysis is significant.
The most crucial source of energy for all living things is glucose. Most cells in the human body prefer glucose as a fuel because red blood cells cannot use anything else.
Most living things engage in some form of glycolysis. It represents the initial phase of cellular respiration.
It is a glycolysis route that results in the partial conversion of pyruvate from glucose. The common mechanism for both aerobic and anaerobic respiration is glycolysis.
Therefore, pyruvic acid is a 3-carbon molecule which is the final products of glycolysis.

b) For example,
specialized cells in the leaves of trees detect the decrease in sunlight
as winter approaches. Chloroplasts then reduce production of green
chlorophyll. As existing chlorophyll is broken down, other coloured
particles are revealed, creating the beautiful red- and orange-coloured
leaves we see during autumn. Th e leaves eventually die and fall off . In

Why do surface currents move in circular patterns?
Answer:
Ocean water moves in predictable ways along the ocean surface. Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change.
Surface currents are created by three things:
global wind patterns
the rotation of the Earth
the shape of the ocean basins
Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
Answer:
The Coriolis effect causes winds and currents to form circular patterns.

4. In a field that is mostly green because of regular rain, the coat color of the mice species that lives there is mostly dark colors. Over a period of 10 years, there is a drought, and the grass has a lot more dead material, making the field have a much lighter over all color. What happens to the population of mice (coat colors) and why?
5. Make up your own scenario (tell me it) and then describe how natural selection would take place with changes.
Answer:
Population of mice having dark coat colors decreases by changing of features of natural selection.
Explanation:
The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.
