A male cardinal’s red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males’ feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
increased variation in the shades of red because there is no advantage in one specific color
increased variation in the shades of red because the cardinals try different ways to impress the females
decreased variation in the shades of red over time because no form of the trait is advantageous
decreased variation in the shades of red after a single generation
Answer:
decreased variation in the shades of red over time because no form of the trait is advantageous
Explanation:
If the vibrant red feathers are no longer used to attract mates, then it is no longer useful to the males, so it will cease to exist.
Answer:
C. decreased variation in the shades of red over time because no form of the trait is advantageous

Which refers to the sum of all the forces that act upon an object?
A. net force
B. absolute force
C. balanced force
D. positive force
Answer:
Net force
Explanation:
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
Answer:
net force
Explanation:
How do the circulatory and respiratory systems deliver important
substances?
Answer:
Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.
A plant cell has a 5%, percent salt concentration. It is placed into a solution
containing a 12%, percent salt concentration.
Explain what will happen to the cell and why?
Answer:
Water in cells moves toward the highest concentration of salt. ... If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt.

Human blood consists of blood groups A, B, and O. However, there is one more blood group, AB, which contains alleles A and B in the same genotype. What is this phenomenon called?
A.
coinheritance
B.
codominance
C.
incomplete dominance
D.
polygenic inheritance
Answer:
B. codominance
Explanation:
because if the placement of the A and B molecules on each cell is controlled by the proteins that are coded by different versions of the same gene, then IA and IB are codominant but both are dominant to Io. If a person receives an IA allele and a IB allele, their blood type is type AB, in which characteristics of both A and B antigens are expressed.
Which of the following solutions would have solute concentration that is lower than the concentration found inside the cell
Answer:
hypotonic solution
A hypotonic solution has a lower solute concentration than inside the cell (the prefix hypo is Latin for under or below). The difference in concentration between the compartments causes water to enter the cell.

In your own words, explain how stalagmites are formed in caves.
Explanation:
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite. Speleothems form at varying rates as calcite crystals build up.What causes changes in cells?

How is the changing environmental quality posing a challenge to agricultural industries?
Soil polluted with heavy metals causes crops to grow more quickly.
Higher birth rates in livestock are due to land pollution.
Water and land pollution make it more difficult to grow healthy crops and livestock.
Droughts cause more people to move to rural areas.
Answer:
Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive, or poorly timed application of pesticides, irrigation water, and fertilizer. Industrial farming practices, such as monocropping and intensive tillage, have also compromised soil health over time. ... Excessive fertilizer use can also cause a buildup of salts in soil, heavy metal contamination and accumulation of nitrate (which is a source of water pollution and also harmful to humans
Explanation:
However agriculture is both cause and victim of water pollution. It is a cause through its discharge of pollutants and sediment to surface and/or groundwater, through net loss of soil by poor agricultural practices, and through salinization and waterlogging of irrigated land.

Numerous atp and naphtha are produced during light reaction why
Answer: cracking of naphtha. It is important to ensure that the feedstock does not crack to form carbon, which is normally formed at this temperature. This is avoided by passing the gaseous feedstock very quickly and at very low pressure through the pipes which run through the furnace Shale naphtha is obtained by the distillation of oil produced from bituminous shale by destructive distillation. Petroleum naphtha is a name used primarily in the United States for petroleum distillate containing principally aliphatic hydrocarbons and boiling higher than gasoline and lower than kerosene.
Explanation: Light naphtha can refer to either a finished product used as a petrochemical feedstock or a distillation cut commonly called light straight run naphtha. It is composed of pentane and slightly heavier material. In a refinery, light naphtha is often blended directly into gasoline.

How does soil erosion affect streams and rivers?
Explanation:
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

4. Choose the microscopy technique that would best fit the needs of each scenario.
Scenario 1: Scientists are attempting to identify the specific type of leukemia a person has based on cell surface structures. ___
Scenario 2: Researchers are studying chemotaxis in white blood cells. Chemotaxis is the movement of living cells in response to a particular substance. ___
Scenario 3: Cell biologists are interested in measuring the distance between the inner and outer nuclear membranes, and need an instrument capable of producing images where the tiny distance between these two membranes is clear. __
Answer: Scenario 1: SEM
Scenario 2: Light
Scenario 3: TEM
Explanation:
The technique applied to observe and analyze objects that cannot be seen with the bared eye is called the microscopic technique.
1. The technique used will be SEM. A scanning electron microscope (SEM) is used to generate an image on the individual surface with the help of electron lasers.
It is useful in apprehending cell surface fabrication and topography.Therefore, to study the cell surface structure of leukaemia SEM is best.2. The light microscopy technique can be applied to study chemotaxis.
When there will be a movement in the living cell due to response towards chemical then the light microscope can be used to visualise the cells.Therefore to study chemotaxis light microscopy should be employed.3. The transmission electron microscope (TEM) method can be used to know the gap between the inner and outer layers. They are used for observing very thin segments of specimens.
Through the thin fragments, the electron flows easily and the image is produced.Therefore, TEM should be used by scientists to measure the distances.To learn more about the microscopy techniques follow the link:
