1. If an animal cell is placed into a solution whose concentration of dissolved substances is
higher than that inside the cell(osmosis). What will happen?
Answer:
Water will move out of the cell causing it to eventually shrink.
Explanation:
The tonicity of solutions determine the direction of water movement. Hypertonic solution is a solution whose concentration is higher than that of its external solution while hypotonic solution is a solution whose concentration is lower than that of its external solution. In this case, an animal cell is placed into a solution whose concentration of dissolved substances is higher than that inside the cell.
This means that the extracellular solution is HYPERTONIC to the cell's solution. Based on OSMOSIS, which is the movement of water from a region of lower solute concentration (high water conc.) to a region of higher solute concentration (low water conc.) via a semipermeable membrane, water will move out of the animal cell into the extracellular solution via the cell membrane (semipermeable membrane).
This movement of water out of the cell will eventually cause it to shrink and die.

PLEASE HELP///3. Heather had a color blindness test, and she was surprised to discover she suffered from red-green colorblindness. She told her biology teacher, who said, “Your father is color-blind too, right?” How did her teacher know this? Why did her teacher not say the same thing to the color-blind males in the class?
Answer:
In order for a woman to have the colorblind trait, they need to be X^cX^c, meaning that they have to get the trait from both their parents. Males can either have X^cY or X^CY and since Heather has it, it is definitive that her father had X^cY, which means that he is colorblind. Males in her class, on the other hand, can get it from either their mother or father.

Please help! Cells inside the body work to keep the dog's temperature stable. True or False?
Answer:
False!
Explanation:
Regulation of the temperature in any body is mostly done by the nervous system. But if a dog wants to maintain homeostasis they will pant as a way to cool off. This physical behavior is their way for regulating their internal temperature, which keeps them from overheating
A: None of the potential offspring would be male, because the potentially male zygote would have two X chromosomes, and the Y chromosome would be ignored.
B: The male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosome.
C: The male offspring would have full-color vision, because of the presence of the extra X chromosome
D: There would be no change to the phenotypes of the possible offspring, because the extra X chromosome would not be active.
Answer: C the male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosomes
Explanation: College board got it correct
The male offspring would all be red-green colour-blind, because of interference from alleles on the Y chromosome. Hence, option B is correct.
What is colour blindness?a diminished capacity to tell some colors apart. Frequently, the condition is hereditary. Medications and specific eye conditions are additional factors. Men are affected more than women.
Inherited color blindness is not treatable. Treating the underlying issue may be helpful if another condition is the cause of color blindness.
The X chromosome is where the genes that might cause red-green color blindness is handed down. Men are more likely than women to have red-green color blindness since it is X-chromosome-inherited. This is due to the fact that males inherit just one X chromosome from their mothers. Hence, option B is correct.

How do enzymes reduce the amount of activation energy needed to make a chemical reaction go?
Answer:
Enzymes reduce the amount of activation energy needed by breaking substrate molecules
Explanation:
Enzymes break down substrate molecules to lower the amount of activation energy required.
What is activation energy?The least amount of energy necessary to bring atoms or molecules into a state where they may cause chemical transformation or physical transport is known as the activation energy in chemistry.
The differential of energy content between atoms or molecules in an active or transition-state configuration and the same atoms and molecules in their original configuration is known as the activation energy in transition-state theory. In mathematical formulas for values like the reaction rate constant, the activation energy is typically denoted by the symbol Ea.
Experimental rate constants or diffusion coefficients that are determined at various temperatures are used to calculate activation energies.
Therefore, Enzymes break down substrate molecules to lower the amount of activation energy required.

what happens when oceanic crust collides with continental crust at plate boundary
Explanation:
When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.
The composition of ocean water can change.
True
False
Ocean Composition can change only if wastes, or substances are introduced into it.
Ocean Composition change?Ocean Composition cannot change because it already contain the fixed amount of constituents in it.
It can change also if some particles or substances are introduced into it.
Ocean refer to water that have more concentration of salt. It is also called seawater and it contain mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of some substances such as particles, gases, dissolved organic and inorganic substances.
Therefore, Ocean Composition cannot change because it already contain the fixed amount of constituents in it.

which of the following requires ATP
A. facilitated diffusion
B.Simple diffusion
C.Active transport
D.None of the above
Answer:
Active transport
Explanation:
The process is considered "active" due to the use of ATP and actively requiring energy to transport molecules. Simple diffusion simply occurs through the membrane and facilitated diffusion uses transport proteins, but not ATP, hence why both are considered forms of "passive" transport.

The DNA sequence TTT codes for the amino acid lysine. The DNA sequence TTC
also codes for lysine. What can you conclude from this information?
Answer:
The genetic code is degenerate and therefore mutations may go unnoticed.
Explanation:
Each triplet of nucleotide bases, which is known as a codon, encodes for a specific amino acid during translation. However, a single amino acid may be coded by different codons. It is for that reason that the genetic code is considered to be degenerate. In this case, Lysine amino acid can be encoded by both TTT (UUU in the mRNA) and TTC (UUC) codons, thereby a mutation T>C at the third nucleotide codon position does not affect the resulting protein (i.e., it is a silent mutation).

What is the equation for calculating the change in water potential? In other words, this equation allows you to determine which way the water will move in response to two different concentrations.
Answer:
The correct answer is - Ψ = ΨS + ΨP.
Explanation:
The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).
Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.
Ψ = ΨS + ΨP.
What are the possible results of speciation?
Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
